Description

Technical Field

[0001] This invention belongs to the field of display panel testing, specifically relating to an automatic snap-opening assembly and feeding structure and testing equipment. Background Technology

[0002] To effectively ensure the quality of display modules, technicians conduct a series of performance tests during the production process. A display module includes a display panel, connectors, and a PCB board. These modules undergo performance testing at different workstations before leaving the factory. To facilitate transfer between these workstations, existing display modules are placed on a carrier board, forming a complete loading unit (see...). Figure 1 The material is loaded to different testing stations by transferring the carrier plate.

[0003] Currently, to prevent the display module from detaching from the carrier plate and being damaged during the transfer and loading process of the loading unit, the carrier plate is usually equipped with a clip (L-shaped structure) to press the display module onto the carrier plate by flipping it.

[0004] However, existing snap-fit ​​devices typically include a pressing end and a flipping end, with the connection between the pressing end and the flipping end hinged to a carrier plate (see...). Figure 2 To avoid interference between the flip end and the detection equipment directly above the display module during testing at different workstations, the flip end is relatively short. Conventional displacement modules have low accuracy, which easily leads to a certain gap (in the height direction) between the push block and the buckle. This often makes it difficult to drive the push block to drive the flip end to flip. Summary of the Invention

[0005] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides an automatic unbuttoning assembly and feeding structure and testing equipment. Its purpose is not only to make the push block in the drive module and the pressing end fit together easily and tightly, reducing the accuracy requirements of the displacement module, but also to prevent the push block from being broken during the process of the push block fitting tightly to the pressing end and driving the flipping end to flip, thus ensuring the service life of the push block.

[0006] In a first aspect, the present invention provides an automatic buckle-opening assembly and feeding structure, the assembly and feeding structure comprising a movable plate and a buckle-opening assembly;

[0007] The buckle-opening assembly includes a driving component and at least one driving module. The driving component is located on the movable plate. The driving module includes a support block, a movable rod, a push block, and an elastic element. The output shaft of the driving component is connected to the support block to drive the support block to move in a first direction. The movable rod extends in a second direction and is movably inserted into and passes through the support block in the second direction. One end of the movable rod has a limiting protrusion that abuts against the support block. The other end of the movable rod is connected to the push block. The push block is used to push the buckle on the carrier plate to flip. The elastic element is sleeved on the movable rod, and both ends of the elastic element abut against the support block and the push block respectively, so that the push block is pressed tightly against the pressing end of the buckle.

[0008] Optionally, the drive module further includes a guide rod, which is parallel and spaced apart from the movable rod. One end of the guide rod is fixed to the push block, and the other end of the guide rod is movably inserted into the support block.

[0009] Optionally, a bushing is inserted into the support block, and the other end of the guide rod is inserted into the bushing.

[0010] Optionally, the limiting protrusion is a gasket, which is locked to one end of the movable rod by bolts.

[0011] Optionally, the push block has a clearance notch for accommodating the flip end of the buckle.

[0012] Optionally, the push block includes a first plate, a second plate, and two connecting plates. The first plate and the second plate are parallel and offset, and are vertically connected by the two connecting plates. The first plate is vertically connected to the other end of the movable rod, and the clearance notch is located on the second plate.

[0013] Optionally, the assembly and feeding structure further includes a displacement component, which includes a first displacement module and a second displacement module. The output end of the first displacement module is connected to the second displacement module in a transmission connection to drive the second displacement module to move along a second direction. The output end of the second displacement module is connected to the movable plate in a transmission connection to drive the movable plate to move along a third direction.

[0014] Optionally, the displacement assembly further includes a support base, on which the first displacement module is located.

[0015] Optionally, the number of drive modules is two, and the drive element is a finger cylinder.

[0016] Secondly, the present invention provides a testing device, which includes an automatic buckle-opening assembly and feeding structure as described in the first aspect.

[0017] The aforementioned improved technical features can be combined with each other as long as they do not conflict with each other.

[0018] In summary, the beneficial effects of the above-described technical solutions conceived by this invention compared with the prior art include:

[0019] In the automatic buckle-opening assembly and feeding structure provided in this embodiment of the invention, the displacement module drives the movable plate to move in space, so that the push block on the drive module is in close contact with the pressing end of the buckle. Since the elastic element is sleeved on the movable rod, and the two ends of the elastic element abut against the support block and the push block respectively, the elastic element will be compressed at this time, and the limiting protrusion will be lifted and spaced from the support block. Under the elastic force of the elastic element, the displacement module can have a high degree of freedom to descend, thereby making it easy for the push block in the drive module to be in close contact with the pressing end, reducing the accuracy requirements of the displacement module.

[0020] Furthermore, the movable rod extends along the second direction and is movably inserted into and passes through the support block along the second direction, allowing the movable rod to move up and down in the vertical direction. Since the push block is tightly against the pressing end, and there is a certain gap R between the hinge shaft of the latch and the connection point between the pressing end and the flipping end (the arc formed with this gap as the radius and the hinge shaft as the center is the arc trajectory S of the push block during movement), the push block will move up and down a certain distance H in the vertical direction during the lateral movement that pushes the pressing end to flip. This allows the push block to move up and down by the movement of the movable rod in the support block during lateral movement, preventing the push block from breaking while it is tightly against the pressing end and driving the flipping end to flip, thus ensuring the service life of the push block. In addition, after the latch is automatically opened, under the elastic force of the elastic element, the push block and movable rod will quickly move down to prepare for the next opening, preventing the movable rod from being stuck in the support block and unable to move down, thus affecting the next opening.

[0021] In other words, the automatic unbuttoning assembly and feeding structure provided by the embodiments of the present invention not only allows the push block in the drive module to easily and tightly attach to the pressing end, reducing the accuracy requirements of the displacement module, but also prevents the push block from being broken during the process of tightly attaching to the pressing end and driving the flipping end to flip, thus ensuring the service life of the push block.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0034] Example:

[0035] Figure 3 This is a schematic diagram of an automatic buckle-opening assembly and feeding structure provided in an embodiment of the present invention, as shown below. Figure 3 As shown, the assembly and feeding structure includes a movable plate 1 and an opening and closing assembly 2.

[0036] Figure 4 This is a structural schematic diagram of the buckle-opening component provided in an embodiment of the present invention, as shown below. Figure 4 As shown, the latching assembly 2 includes a driving member 21 and at least one driving module 22. The driving member 21 is located on the movable plate 1. The driving module 22 includes a support block 221, a movable rod 222, a push block 223, and an elastic member 224. The output shaft of the driving member 21 is connected to the support block 221 to drive the support block 221 to move along a first direction (X-axis direction). The movable rod 222 extends along a second direction (Z-axis direction) and is movably inserted into the support block along the second direction. 221 passes through the support block 221. One end of the movable rod 222 has a limiting protrusion 2221 that abuts against the support block 221. The other end of the movable rod 222 is connected to the push block 223. The push block 223 is used to push the buckle 200 on the carrier plate 100 to flip. The elastic element 224 is sleeved on the movable rod 222, and both ends of the elastic element 224 abut against the support block 221 and the push block 223 respectively, so that the push block 223 is close to the pressing end 201 of the buckle 200.

[0037] In the automatic buckle-opening assembly and feeding structure provided in this embodiment of the invention, the movable plate 1 is moved in space by the displacement module, so that the push block 223 on the drive module 22 is in close contact with the pressing end 201 of the buckle 200. Since the elastic element 224 is sleeved on the movable rod 222, and the two ends of the elastic element 224 abut against the support block 221 and the push block 223 respectively, the elastic element 224 will be compressed at this time, and the limiting protrusion 2221 will be lifted and spaced apart from the support block 221. Under the elastic force of the elastic element 224, the displacement module can have a high degree of freedom to descend, so that the push block 223 in the drive module 22 can be easily and tightly attached to the pressing end 201, reducing the accuracy requirements of the displacement module.

[0038] Furthermore, the movable rod 222 extends along the second direction and is movably inserted into and passes through the support block 221 along the second direction, allowing the movable rod 222 to move and rise vertically. Since the push block 223 is in close contact with the pressing end 201, and there is a certain gap R between the hinge shaft 203 of the latch 200 and the connection points of the pressing end 201 and the flipping end 202 (see...) Figure 2 The arc formed with the interval as the radius and the hinge shaft 203 as the center is the arc trajectory S of the push block 223 during movement. Therefore, during the process of the push block 223 moving laterally to push the pressing end 201 to flip, it will rise and fall a certain distance H in the vertical direction. This allows the push block 223 to rise and fall through the movement of the movable rod 222 in the support block 221 during the lateral movement, preventing the push block 223 from breaking while it is in close contact with the pressing end 201 and driving the flipping end 202 to flip, thus ensuring the service life of the push block 223. In addition, after the push buckle 200 is automatically opened, under the elastic force of the elastic element 224, the push block 223 and the movable rod 222 will quickly move down to prepare for the next opening, preventing the movable rod 222 from being stuck in the support block 221 and unable to move down, thus affecting the next opening.

[0039] In other words, the automatic unbuttoning assembly and feeding structure provided by the embodiments of the present invention not only allows the push block 223 in the drive module 22 to easily and tightly attach to the pressing end 201, reducing the accuracy requirements of the displacement module, but also prevents the push block 223 from being broken during the process of tightly attaching to the pressing end 201 and driving the flipping end 202 to flip, thus ensuring the service life of the push block 223.

[0040] It should be noted that the drive component 21 can be a cylinder or a linear module. The elastic component 224 can be a spring.

[0041] In one implementation of the invention, the number of driving modules 22 can be two, corresponding to the case where there are two clips 200 on the carrier plate 100. The two clips 200 further ensure the reliability of the display module 300 being pressed in. In this case, the driving component 21 can correspond to a finger cylinder, that is, the finger cylinder simultaneously drives the two support blocks 221 to move closer or further apart.

[0042] For example, the support block 221 includes a first support plate and a second support plate, the first support block and the second support block are vertically connected, and the first support block is located on the output shaft of the drive member 21, while the movable rod 222 is inserted into the second support plate.

[0043] See also Figure 4 The drive module 22 also includes a guide rod 225, which is parallel and spaced apart from the movable rod 222. One end of the guide rod 225 is fixed on the push block 223, and the other end of the guide rod 225 is movably inserted into the support block 221.

[0044] In the above embodiment, the guide rod 225 can guide the lifting and lowering of the movable rod 222, making the process of the movable rod 222 driving the push block 223 to rise and fall more stable.

[0045] Furthermore, a bushing is inserted into the support block 221, and the other end of the guide rod 225 is inserted into the bushing, which not only allows for precise positioning of the guide rod 225, but also reduces the frictional force on the movable rod 222.

[0046] In one implementation of the present invention, the limiting protrusion can be a gasket. The gasket is locked to one end of the movable rod 222 by bolts, thereby facilitating the fixing of the gasket at the top of the movable rod 222. The gasket also serves to limit the movable rod 222 when the push block 223 does not contact the buckle 200, preventing the movable rod 222 from falling off the support block 221.

[0047] Figure 5 This is a schematic diagram of the pusher block provided in an embodiment of the present invention, as shown below. Figure 5 As shown, the push block 223 has a clearance notch 2231, which is used to accommodate the flip end 202 of the latch 200.

[0048] It is easy to understand that by setting the clearance notch 2231, reliable contact can be achieved between the push block 223 and the flip end 202 of the buckle 200 during the lateral movement of the push block 223, so as to prevent the two from separating and ensure that the buckle 200 flips reliably.

[0049] Furthermore, the push block 223 includes a first plate 2232, a second plate 2233 and two connecting plates 2234. The first plate 2232 and the second plate 2233 are parallel and offset, and are vertically connected by the two connecting plates 2234. The first plate 2232 is vertically connected to the other end of the movable rod 222, and the clearance notch 2231 is located on the second plate 2233.

[0050] It is easy to understand that the first plate 2232 and the second plate 2233 are parallel and offset, and connected by two connecting plates 2234, so that the push block 223 has an overall Z-shaped structure, reducing its mass and allowing it to avoid obstructing the detection equipment while also preventing the push block 223 from being too heavy. In addition, the two connecting plates 2234 can increase the connection strength between the first plate 2232 and the second plate 2233, preventing breakage when pushing the top latch 200.

[0051] For example, the first plate 2232, the second plate 2233, and the two connecting plates 2234 are integrally formed. In addition, the second plate 2233 has a U-shaped structure.

[0052] See also Figure 3 The assembly and feeding structure also includes a displacement component 3 (i.e., the displacement module mentioned above). The displacement component 3 includes a first displacement module 31 and a second displacement module 32. The output end of the first displacement module 31 is connected to the second displacement module 32 to drive the second displacement module 32 to move along the second direction (Z-axis direction). The output end of the second displacement module 32 is connected to the movable plate 1 to drive the movable plate 1 to move along the third direction (Y-axis direction).

[0053] For example, after the carrier plate 100 is placed, the second displacement module 32 first drives the movable plate 1 to move along the Y-axis to directly above the carrier plate 100. Then, the first displacement module 31 drives the second displacement module 32 and the movable plate 1 to descend along the Z-axis, so that the push block 223 is in close contact with the pressing end 201 of the latch 200. Finally, the drive component 21 drives the drive module 22 to move along the X-axis, thereby causing the latch 200 to flip and thus automatically open. After the latch 200 is opened, the drive component 21 drives the drive module 22 to continue moving along the X-axis and disengage from the latch 200. Then, the second displacement module 32 drives the movable plate 1 to move backward along the Y-axis. Finally, the first displacement module 31 drives the second displacement module 32 and the movable plate 1 to rise along the Z-axis, while the drive component 21 drives the drive module 22 to move backward along the X-axis, thereby making space for the robot to place the display module 300 onto the carrier plate 100 and preparing for the next latch opening.

[0054] For example, the first displacement module 31 and the second displacement module 32 can be cylinders or linear modules. Additionally, this assembly and loading structure may also include a controller, which is electrically connected to the drive unit 21, the first displacement module 31, and the second displacement module 32, thereby achieving automated control.

[0055] Furthermore, the displacement assembly 3 also includes a support base 33, on which the first displacement module 31 is located. The support base 33 serves to raise the first displacement module 31 in the Z-axis direction, preventing the first displacement module 31 from having an excessively large lifting stroke.

[0056] This invention also provides a testing device, which includes an automatic buckle-opening assembly and feeding structure as described above.

[0057] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
