It enables efficient and rapid handling, pressing, and alignment of the product, improving testing stability and alignment accuracy. At the same time, by changing the action flow and movement sequence of pressing and alignment with the testing device, from the testing device pressing down to the support component actively aligning and pressing with the testing device under the action of the lifting drive component, the pressure burden on the support device is reduced, and the hidden dangers caused by the low load-bearing rigidity of the base are eliminated.

[0038] Figure 5 This diagram shows the connection between the third guide rail and the mounting platform provided in an embodiment of the present invention. Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not the entire structure.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" 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 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] In this invention, unless otherwise expressly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0042] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0043] The existing bearing mechanism has drawbacks when used for testing new products with an area three times larger or even larger than the original one. These include high manpower consumption for loading and unloading, poor product alignment, and low rigidity of the base, making it unsuitable for bearing large-sized products. The original pressing test uses an upper descending pressing mechanism and an upper alignment mechanism for alignment. For new products with an area three times larger, this pressing method requires a redesign of a large-volume pressing mechanism. The large-volume pressing mechanism and alignment mechanism will place a huge pressure burden on the overall equipment, thus creating potential problems for the test.

[0044] To address the shortcomings of existing technologies, this utility model provides a supporting device, combined with... Figure 1-5 As shown, the support device includes a base 1, a rotating component 3 mounted on the base 1 via a mounting platform 2, a lifting drive component disposed between the mounting platform 2 and the base 1, and a support component 5 mounted on the output end of the rotating component 3. The side surface of the support component 5 away from the rotating component 3 is used to support the product to be tested.

[0045] The base 1 is provided with a first guide rail group and a second guide rail group, such as Figure 4 As shown, the first guide rail group is located on the side surface of the base 1 near the mounting platform 2 and extends along the X direction, while the second guide rail group is located on the two opposite sides of the base 1 along the X direction and extends along the Z direction.

[0046] The lifting drive assembly includes a drive component 41 and a third guide rail group slidably connected to the first guide rail group via a connecting plate 42. The connecting plate 42 can drive the third guide rail group to move in the X direction under the action of the drive component 41.

[0047] The third guide rail group extends along the X direction and is inclined from one end to the other along the Z direction.

[0048] The mounting platform 2 is slidably connected to the second guide rail group and is relatively connected to the base 1 through the second guide rail group; the mounting platform 2 is slidably connected to the third guide rail group and is relatively connected to the connecting plate 42 through the third guide rail group.

[0049] The mounting platform 2 can move along the first guide rail group with the connecting plate 42, causing the rotating component 3 and the bearing component 5 to rise and fall in the Z direction along the second and third guide rail groups. The bearing component 5 carries the product under test to rise, so that the product under test can be aligned and pressed with the pressing mechanism of the testing device and conduction.

[0050] In a specific embodiment, such as Figure 4-5 As shown, the first guide rail group includes multiple first guide rails 6 arranged in an array on the base 1. The first guide rails 6 extend along the X direction, enabling the connecting plate 42 to drive the third guide rail group to move smoothly along the X direction. The base 1 has multiple weight-reducing holes 10 arranged in an array, reducing the overall weight of the load-bearing device without affecting the structural strength and load-bearing rigidity of the base 1. The multiple first guide rails 6 are respectively arranged on two opposite sides of the weight-reducing holes 10 in the X direction, forming the first guide rail group. The multiple first guide rails 6 together guide the movement of the connecting plate 42 in the X direction, improving the stability of its movement.

[0051] like Figure 4 As shown, the second guide rail assembly includes multiple second guide rails 7 evenly distributed on two opposite sides of the base 1 along the X direction. The second guide rails 7 extend along the Z direction. The four edges of the mounting platform 2 are slidably connected to the second guide rails 7, which guide and limit the lifting and lowering of the mounting platform 2, so that it can only move in the Z direction and not in the X direction.

[0052] The third guide rail group includes multiple third guide rails 8 disposed on the side of the connecting plate 42 away from the base 1. The third guide rails 8 are arranged in a one-to-one correspondence with the first guide rails 6. The third guide rails 8 are inclined guide rails, extending along the X direction and inclined from one end to the other along the Z direction. When the connecting plate 42 moves relative to the base 1 in the X direction under the action of the driving member 41, the third guide rails 8 and the mounting platform 2 move relative to each other. Since the displacement of the mounting platform 2 in the X direction is restricted by the second guide rail group, the mounting platform 2 is pushed by the third guide rails 8 and rises and falls in the Z direction.

[0053] like Figure 5 As shown in Figures a and b, when the connecting plate 42 moves along the X direction, causing the connection end between the mounting platform 2 and the third guide rail 8 to move from the lowest end to the highest end, the mounting platform 2 rises along the second guide rail 7, allowing the product under test and the testing device located on the bearing assembly 5 to be pressed and connected. When the connecting plate 42 moves along the X direction, causing the connection end between the mounting platform 2 and the third guide rail 8 to move from the highest end to the lowest end, the mounting platform 2 descends along the second guide rail 7 to load and unload the product.

[0054] In one specific embodiment, the mounting platform 2 is mounted on the third guide rail 8 via a slider 20. The slider 20 includes an inclined groove 201 that corresponds to and cooperates with the third guide rail 8, and a mating surface 202 located on the side of the inclined groove 201 away from the third guide rail 8. The mating surface 202 is parallel to the horizontal plane. The surface of the mounting platform 2 away from the rotating component 3 is fixedly engaged with the mating surface 202, so that the rotating component 3 and the bearing component 5 can be horizontally mounted on the base 1. The connecting plate 42 is driven to move in the X direction by the driving member 41, causing relative movement between the third guide rail 8 and the slider 20, thereby driving the mounting platform 2 to rise and fall along the second guide rail 7.

[0055] In one specific example, the driving component 41 includes a drive motor 411 and a lead screw 412 fixed to the output end of the drive motor 411. A moving block is provided on the lead screw 412, which can move along the lead screw 412 as it rotates. The connecting plate 42 is fixedly connected to the moving block. The drive motor 411 drives the lead screw 412 to rotate, and the moving block drives the connecting plate 42 to move in the Z direction. In other examples, the driving component 41 can also be a horizontal cylinder, which drives the connecting plate 42 to move in the Z direction through the extension and retraction of the cylinder rod.

[0056] In a specific embodiment, such as Figure 3 As shown, the rotating assembly 3 includes a rotating motor 31 and an annular track that are fixed to the side surface of the mounting platform 2 away from the base 1. The rotating motor 31 is located at the center of the annular track, and the output shaft of the rotating motor 31 is arranged along the Z direction. The bearing assembly 5 is fixed to the output shaft and can rotate around the Z direction with the output shaft.

[0057] In this embodiment, the bottom of the support component 5 is slidably connected to the annular track, and can rotate around the Z direction along the annular track under the action of the rotary motor 31. The annular track ensures the smoothness of the movement of the support component 5.

[0058] In a specific embodiment, such as Figure 3 As shown, the annular track includes a track section 321 with an annular structure and a slider section 322 slidably disposed on the track section 321. The slider section 322 has an annular structure and is coaxially disposed with the track section 321. The bottom of the bearing assembly 5 is fixedly connected to the slider section 322, and can rotate along the track section 321 with the slider section 322 under the drive of the rotary motor 31, thereby improving the smoothness of the movement of the bearing assembly 5.

[0059] Furthermore, in a specific example, such as Figure 3As shown, a first support unit and a second support unit are fixedly attached to the top of the slider part 322. The first support unit and the second support unit are symmetrically arranged about one diameter of the slider part 322. The top of the first support unit and the second support unit are provided with pin holes 3230, and the bottom of the bearing assembly 5 is provided with mounting holes. The pin holes 3230 and the connecting holes are connected by pins 324 to connect and fix the bearing assembly 5 and the slider part 322.

[0060] In this embodiment, the first support unit and the second support unit each include five support blocks 323. The support blocks 323 are fixed to the top of the slider part 322, connecting the slider part 322 and the bearing assembly 5. They serve to raise the bearing assembly 5 to prevent the bottom part of the bearing assembly 5 from colliding with the annular track, and also to support the bearing assembly 5. Each support block 323 has a pin hole 3230 on its top. A pin 324 connects the pin hole 3230 to the mounting hole at the bottom of the bearing assembly 5 to fix the bearing assembly 5 to the slider part 322.

[0061] In one specific embodiment, the carrier device includes at least two testing stations, each performing different testing operations. The rotating component 3 drives the carrier component 5 to move between the testing stations, ensuring that the pressing area of ​​the product under test carried by the carrier component 5 is aligned and pressed with the testing device at the corresponding testing station. In a specific example, the carrier device includes two testing stations. After the carrier component 5 completes testing at the first testing station, based on preset conditions, it is determined whether the carrier component 5 needs to be rotated by the rotating component 3 to the second testing station for subsequent testing.

[0062] In one specific embodiment, a position sensor 50 is provided at the bottom of the support component 5. The position sensor 50 is used to sense the position of the support component 5 and determine whether it has rotated to the designated detection station.

[0063] Correspondingly, a sensing component 21 is fixedly attached to the side of the mounting platform 2 near the bearing assembly 5. The sensing component 21 is correspondingly set on the outer side of the circular track, and is set to cooperate with the position sensor 50 at each detection station of the bearing device. When the bearing assembly 5 moves between different detection stations, the position sensor 50 moves with the bearing assembly 5 under the drive of the rotating assembly 3 from a state cooperating with one sensing component 21 to a state cooperating with the next sensing component 21. The position sensor 50 locates the position of the bearing assembly 5 by sensing the sensing component 21, and determines whether it has moved to the corresponding detection station, thereby improving the accuracy of the displacement of the bearing assembly 5 and further ensuring the accurate alignment between the product under test and the testing device.

[0064] In one specific embodiment, the carrier component 5 is used, for example, to carry the display module to be tested, such as... Figure 2 As shown, the supporting component 5 includes a supporting plate 51, a support structure located below the supporting plate 51, and a lifting structure 52; wherein, the support structure includes a plurality of support units arranged in an array; the plurality of support units are used to support the object to be supported.

[0065] In this embodiment, the lifting structure 52 is used to drive the support structure so that the support end of the support unit moves to a position above the top surface of the carrier plate 51. That is, through the driving of the lifting structure 52, the support end of the support unit extends out of the top surface of the carrier plate 51 and abuts against the object to be carried. Then, the lifting structure 52 drives the support unit to descend so that the product to be tested is placed on the carrier plate 51.

[0066] In addition, the support structure in this embodiment includes two first sides arranged opposite to each other, such as Figure 2 As shown, the two first sides can be, for example, the left and right opposite sides or the front and back opposite sides of the support structure. The height of the support unit corresponding to the edge of the two first sides is higher than the height of the support unit between the edges of the two first sides.

[0067] In a specific example, the two first sides are left and right opposite sides. The support structure includes several columns of support units arranged along the row direction. The middle area between the left and right sides includes several columns of support units. The height of a column of support units at the edge of the left side and a column of support units on the right side are higher than the height of several columns of support units between the left and right sides, respectively. So when the support units abut against the display module, the two columns of support units located on the left and right opposite sides abut against the display module first, and then the several columns of support units located between the left and right sides contact the display module.

[0068] In another specific example, the two first sides are front and rear opposite sides, and the support structure includes several rows of support units arranged along the column direction. The middle area between the front side and the rear side includes several rows of support units. The height of a row of support units at the edge of the front side and a row of support units at the edge of the rear side are higher than the height of several rows of support units between the front and rear sides and the rear side, respectively. So when the support unit abuts against the display module, the support unit located on the front and rear opposite sides abuts against the display module first, and then the several rows of support units located between the front and rear sides contact the display module.

[0069] In this embodiment, the support component 5 first drives the support structure through the lifting structure 52 to move the support ends of several support units upward to a position above the top surface of the support plate 51. At the same time, the robotic arm lifts the display module to be tested and moves it above the support unit. The robotic arm places the display module above the support end of the support unit, and the display module abuts against the support end of the support unit. Since the height of the support unit corresponding to the two first side edges of the support structure is higher than the height of the support unit between the two first side edges, the display module is recessed.

[0070] Subsequently, the lifting structure 52 drives the support unit to move downward, thereby causing the display module to move downward synchronously. This ensures that the display module descends in sync. The recessed part of the display module first contacts the carrier plate 51, and then the side of the display module contacts the carrier plate 51. This ensures that the air between the display module and the carrier plate 51 is completely expelled, so that the display module and the carrier plate 51 are flat and fit together. This effectively improves the flatness of the product under test and ensures that there are no gaps between the product under test and the carrier plate 51, which facilitates subsequent testing operations. In addition, it can also avoid the problem of the display module breaking due to uneven placement during vacuuming.

[0071] Furthermore, after the inspection is completed, the lifting structure 52 drives the support unit to move the display module upward. The height of the support unit corresponding to the two first side edges is higher than the height of the support unit between the two first side edges, so that the position of the display module corresponding to the first side edge first contacts the support unit and is lifted up. Then, the support unit between the two first sides then abuts against the display module, thereby driving the entire display module to detach from the carrier plate 51. Finally, a robotic arm is inserted between the display module and the carrier plate 51, lifting the display module and moving it to the next work station. This embodiment can realize the rapid peeling of the display module, which is convenient for the robotic arm to lift the display module subsequently. It works well with existing robotic arms and prevents damage to the display module caused by the direct lifting of the display module by the existing robotic arm. At the same time, it improves the efficiency of picking up and placing the display module and the inspection efficiency.

[0072] In one specific embodiment, the support plate 51 covers the functional area of ​​the support structure, that is, the support plate 51 covers several arrayed support units, thereby making the structure of the support component 5 more compact and saving the space occupied by the support component 5. At the same time, the support plate 51 can also protect the support structure and prevent the support structure from scratching other equipment.

[0073] In one specific implementation, such as Figure 2As shown, the support structure includes several support units arranged along the X direction. Each support unit includes several support rods 53 arranged along the Y direction, which is perpendicular to the X direction. The end of the support rod 53 away from the lifting structure 52 is the support end of the support unit, and the two first sides are opposite sides in the X direction.

[0074] In a specific example, such as Figure 2 As shown, the support structure includes several support units arranged along the X direction, and each column of support units includes several support rods 53 arranged along the Y direction, wherein, as shown... Figure 2 As shown, the support structure includes 8 columns of support units, and each column of support units includes 6 support rods 53. The top of the support rod 53 is the support end of the support unit. In this specific example, the two first sides are two opposite sides, which are arranged opposite each other in the row direction.

[0075] In another specific example, the support structure includes several support units arranged along the Y direction, and each column of support units includes several support rods 53 arranged along the X direction. The support structure comprises 6 columns of support units, and each column of support units includes 8 support rods 53. The top of each support rod 53 is the support end of the support unit. In this specific example, the two first sides are front and rear sides, which are arranged opposite each other in the column direction.

[0076] In one specific embodiment, the support plate 51 includes a plurality of through holes 510 corresponding to the support rods 53, through which the support rods 53 can pass. Specifically, the support rods 53 pass through the through holes 510. In a specific example, in the initial state, the supporting end of the support rod 53 is located inside or below the through hole 510; in the working state, the lifting structure 52 drives the support rod 53 through the through hole 510, so that the supporting end of the support rod 53 is located above the top surface of the support plate 51. This embodiment, by providing through holes 510, can protect the support rods 53 when not in use. In addition, the through holes 510 can also ensure that the support rods 53 can move vertically up and down, preventing the support rods from tilting, thereby ensuring effective support for the display module.

[0077] In one specific embodiment, the support end of the support rod 53 is provided with a negative pressure suction nozzle. In the initial state, the negative pressure suction nozzle is located inside or below the through hole 510. In the working state, the lifting structure 52 drives the support rod 53 through the through hole 510, and the negative pressure suction nozzle is located above the top surface of the support plate 51. The negative pressure suction nozzle is connected to a negative pressure device for adsorbing and fixing the product to be tested.

[0078] In one specific embodiment, the support structure includes a plurality of support units arranged side by side between the two first side edges, and the height of the support unit between the two first side edges decreases in the direction extending from the two first side edges toward the center.

[0079] In a specific example, the two first sides of the support structure are a left side and a right side arranged opposite to each other. The support structure includes several columns of support units arranged along the row direction. Each column of support unit includes several support rods 53 arranged along the column direction. The middle area between the left side and the right side includes several columns of support units, such as... Figure 2 As shown, the central area includes six columns of support units, divided by the center line of the central area into three columns on the left and three columns on the right. These three columns are symmetrically arranged with respect to the center line of the central area. Furthermore, the height of the three columns on the left decreases from the left side towards the center; similarly, the height of the three columns on the right decreases from the right side towards the center.

[0080] In one specific implementation, such as Figure 2 As shown, the lifting structure 52 includes a support frame 521 for supporting the support rod 53 and a motor 522 that is connected and fixed to the support plate 51. The support frame 521 is connected and fixed to one end of the support unit away from the support end. The support frame 521 is configured to drive the support structure to move along the Z direction under the action of the motor 522.

[0081] In a specific example, the support frame 521 is fixedly connected to the bottom end of the support rod 53 on the side near the bearing plate 51. The motor 522 is used to drive the support frame 521 to move vertically up and down, thereby driving the support rod 53 on the support frame 521 to move upward through the through hole 510 or downward into the through hole 510.

[0082] In one specific implementation, the plane of the support frame 521 is parallel to the plane of the bearing plate 51. In a specific example, both the support frame 521 and the bearing plate 51 are horizontally arranged, thereby ensuring that the bottom end of the support rod 53 arranged on the support frame 521 is located on the same horizontal plane, that is, ensuring that the support rod 53 moves synchronously from the same horizontal plane along the support direction of the support structure, ensuring the stability of the display module supported by the support rod 53, and preventing the display module from tilting.

[0083] In one specific embodiment, the output shaft of the motor 522 is connected to a transmission element, and is connected to a transmission screw extending along the Z direction via the transmission element. The support frame 521 has a nut fitted onto the transmission screw, with the nut located on the upper and lower sides of the support frame 521. Driven by the motor 522, the transmission element drives the transmission screw to rotate, causing the nut to move up and down via threaded transmission, thereby driving the support frame 521 to move up or down.

[0084] In a specific example, motor 522 may be a servo motor, for example. It is understood that motor 522 may also be replaced by a hydraulic cylinder drive. The output end of the hydraulic cylinder is fixedly connected to the support frame 521, and the support frame 521 is driven to move in the Z direction by the extension and retraction of the cylinder rod.

[0085] In one specific embodiment, the supporting device further includes multiple alignment components 9 disposed on the surrounding sidewalls of the supporting plate 51. Each alignment component includes an alignment rod, a first cylinder driving the alignment rod to move along the Z direction, and a second cylinder driving the alignment rod to move along the X or Y direction. During the placement of the product under test on the supporting plate 51, the top of the alignment rod is lower than the surface of the supporting plate 51 to prevent the alignment rod from abutting the bottom of the product under test. After the product under test is placed on the supporting plate 51, the alignment rod, driven by the first cylinder, moves upward until its top is flush with or exceeds the product under test, ensuring that the alignment rod remains to the side of the product under test during its ascent. Then, driven by the second cylinder, the alignment rod moves towards the product under test to contact its edge. The multiple alignment components 9 cooperate to center the position of the product under test relative to the supporting plate 51, thereby improving the alignment accuracy during subsequent crimping and connection with the testing device.
