[0002] When the display module is being tested, it can be fixed on the carrier. In this way, the carrier can carry the display module and transfer it between different testing equipment, avoiding the need to press the display module with each testing equipment separately, thereby improving testing efficiency.

[0063] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

Furthermore, the figures are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale.

[0064] Although relative terms such as "upper" and "lower" are used in this specification to describe the relationship of one illustrated component to another, these terms are used herein for convenience only, such as in accordance with the orientation of the illustrations in the accompanying drawings. It will be understood that if the illustrated device were flipped upside down, the component described as "upper" would become the component "lower." When a structure is referred to as "on" another structure, this may mean that the structure is integrally formed with the other structure, that the structure is "directly" disposed on the other structure, or that the structure is "indirectly" disposed on the other structure via the other structure.

[0065] The terms "a", "an", "the", "said" and "at least one" are used to indicate the presence of one or more elements / components / etc.; the terms "including" and "having" are used to express open-ended inclusion and mean that additional elements / components / etc. may be present in addition to the listed elements / components / etc.; the terms "first", "second" and "third" etc. are used only as labels and are not intended to limit the quantity of their objects.

[0066] The embodiments of the present disclosure provide a carrying platform and a detection device that cooperates with the carrying platform. Specifically, a base on the detection device that cooperates with the carrying platform is provided.

[0067] Referring to Figures 1 to 3, the carrying platform CA includes a carrying platform CA1 for carrying the display module MDL and a suction nozzle NOZ arranged on the carrying platform CA1; the carrying platform CA also includes a negative pressure component (not shown in Figures 1 to 3); wherein, the negative pressure component is used to provide negative pressure to the suction nozzle NOZ so that the suction nozzle NOZ can adsorb the display module MDL located on the carrying platform CA1.

[0068] In this embodiment, when the display module MDL needs to be inspected, the display module MDL can be carried on the carrier CA1 of the carrier CA, and then negative pressure is provided to the suction nozzle NOZ through the negative pressure component, so that the suction nozzle NOZ can adsorb the display module MDL with the help of the negative pressure, thereby fixing the display module MDL. In this embodiment, the suction nozzle NOZ is located below the display module MDL, so it will not be restricted by the edge position and shape of the display module MDL, and can be applied to display modules MDL of various forms, overcoming the defect that the clamping mechanism cannot be applied to fix heterogeneous display modules MDL and large-angle display modules MDL (such as the display module MDL of the waterfall screen). Therefore, the carrier CA of this embodiment has strong versatility, which can reduce the cost of display module MDL inspection. In addition, in the related art, when the clamping mechanism clamps the display module MDL, there is a risk of damage to the display module MDL. In the embodiment of the present disclosure, the carrying platform CA absorbs the display module MDL through the suction nozzle NOZ, which does not cause clamping damage to the display module MDL, thereby reducing the risk of damage to the display module MDL during the fixing process.

[0069] As follows, the structure, principle and effect of the carrying platform of the embodiment of the present disclosure are further explained and illustrated with reference to the accompanying drawings.

[0070] Figure 4 shows a schematic diagram of the structure of the mutual cooperation of the carrying platform CA, the base BA and the display module MDL in one embodiment. Referring to Figure 4, the carrying platform CA is used to carry the display module MDL and fix the carried display module MDL by adsorption. The base BA is provided on the detection device and is used to be detachably connected to the carrying platform CA so that the carrying platform CA and the display module MDL carried by the carrying platform CA are fixed on the detection device. When the display module MDL needs to be transferred to another detection device for detection, the carrying platform CA can be separated from the base BA of the current detection device, and then the carrying platform CA can be transferred and fixed to the base BA of another detection device, thereby realizing the flow of the display module MDL between different detection devices. Figures 5-1 to 5-3 illustrate a schematic diagram of the process of the display module MDL flowing from the first detection device AA1 to the second detection device AA2 in one embodiment. Referring to Figure 5-1, the first detection device AA1 and the second detection device AA2 are each provided with a base BA, and the carrying platform CA carrying and fixing the display module MDL is fixedly connected to the base BA of the first detection device AA1. When the display module MDL is in circulation, the carrier CA carrying the display module MDL can be separated from the base BA of the first inspection device AA1 (as shown in Figure 5-2), and then the carrier CA carrying the display module MDL can be fixed to the base BA of the second inspection device AA2 (as shown in Figure 5-3). In this way, the display module MDL does not need to be separated from the carrier CA during circulation, avoiding repeated pressure connection between the display module MDL and the carrier CA, and further reducing the risk of quality damage to the display module during the inspection process.

[0071] In one embodiment of the present disclosure, referring to FIG3 , the display module MDL includes a display panel and a flexible circuit board bound and connected to the display panel. In the display device, the flexible circuit board can be connected to a control component (such as a circuit board, etc.) so that the signal of the control component can be sent to the display panel. When performing a display module MDL inspection, the inspection device can send a signal to the display panel through the flexible circuit board, and then detect the response of the display panel (including but not limited to electrical response and optical response). It will be understood that in some embodiments, the display module may also include other components, such as a glass cover plate, a back plate, etc.

[0072] In one embodiment of the present disclosure, referring to FIG3 , the carrying platform CA may further include a crimping platform CA2, on which a crimping joint JA is provided. The display panel of the display module MDL may be carried on the carrying platform CA1 and fixed by adsorption through the suction nozzle NOZ. The flexible circuit board of the display module MDL may be crimped with the crimping joint JA to achieve electrical connection. In this way, the display module MDL to be inspected forms a circulating workpiece with the carrying platform CA. Referring to FIG4 and FIG6 , the base BA of the inspection device has a fixing mechanism BA1 and a switching circuit BA4; the base BA may fix the carrying platform CA through the fixing mechanism BA1; the switching circuit BA4 may be detachably electrically connected to the crimping joint JA. In this way, the inspection device may load a signal to the display module MDL through the switching circuit BA4 of the base BA and the crimping joint JA of the carrying platform CA, and perform corresponding inspections. When the inspection is completed, the circulating workpiece may be separated from the base BA, specifically, the fixing mechanism BA1 of the base BA releases the carrying platform CA and the switching circuit BA4 is separated from the crimping joint JA. In this way, the transferred workpiece can be transferred to the next testing device for the next testing process. In one example, the transfer circuit BA4 can be a probe module (POGO module).

[0073] In one embodiment of the present disclosure, the carrier platform CA1 is detachably connected to the crimping platform CA2. In this way, when it is necessary to test a new display module MDL, the crimping platform CA2 can be determined based on the flexible circuit board of the new display module MDL. When the crimping joint JA of the original crimping platform CA2 does not match the new flexible circuit board, the carrier platform CA can be replaced with an adapted crimping platform CA2 to enable the carrier platform CA to be applicable to the new display module MDL. In this way, the parts of the carrier platform CA other than the crimping platform CA2 can be shared in different display module MDL tests, which can improve the versatility of the carrier platform CA, thereby reducing the cost of the carrier platform CA and reducing the switching time when switching between different display module MDL tests.

[0074] In one example, the crimping platform CA2 is located on one side of the carrier CA1 in the first direction. When the display module MDL is placed on the carrier CA, the display panel is placed on the carrier CA1 and secured by the suction nozzle NOZ. The flexible printed circuit board is located on one side of the display panel in the first direction, extending toward and connecting to the crimping joint JA.

[0075] In the disclosed embodiment, the two orthogonal directions within the plane of the carrier CA are referred to as the first direction and the second direction, respectively. The crimping platform CA2 is located on the first side of the carrier CA1. The direction perpendicular to the plane of the carrier CA is referred to as the third direction. The first, second, and third directions are mutually perpendicular.

[0076] In one embodiment of the present disclosure, the carrying platform CA further includes a base plate CA3. Referring to FIG2 , the carrying platform CA1 and the crimping platform CA2 are both fixed to the same side of the base plate CA3. For example, the carrying platform CA1 and the crimping platform CA2 are both located on the third side (above) of the base plate CA3.

[0077] Optionally, the crimping platform CA2 is detachably connected to the base plate CA3, so that the carrier CA1 and the crimping platform CA2 are detachably connected. When the carrier CA needs to be replaced with the crimping platform CA2, the original crimping platform CA2 can be separated from the base plate CA3 and the new crimping platform CA2 can be connected to the base plate CA3.

[0078] In one embodiment of the present disclosure, as shown in FIG7 , a receiving cavity DPG is defined between the base plate CA3 and the carrier CA1, and the negative pressure assembly DP is at least partially housed within the receiving cavity DPG. Thus, the negative pressure assembly DP is at least partially housed within the carrier CA, improving the neatness of the carrier and avoiding the increased difficulty in operation and maintenance caused by placing the negative pressure assembly DP externally.

[0079] Optionally, the accommodating chamber DPG is opened on the carrier platform CA1, and the bottom plate CA3 covers the opening of the accommodating chamber DPG. For example, the carrier platform CA1 includes a top plate and side walls connected to the edge of the top plate; the top plate and the side walls surround the accommodating chamber DPG, and the bottom plate CA3 covers the opening of the accommodating chamber DPG. A nozzle cavity for accommodating the suction nozzle NOZ is provided on the top plate. In this example, the accommodating chamber DPG is opened on the carrier platform CA1 and opens downward, and the bottom plate CA3 is located below the accommodating chamber DPG and covers the opening of the accommodating chamber DPG to protect the negative pressure component DP located therein.

[0080] In one example, the sidewalls include two first sidewalls located on either side of the top plate in the second direction. Along the second direction, the top plate is sandwiched between the two first sidewalls. Along the third direction, the first sidewalls are sandwiched between the top plate and the bottom plate CA3. Thus, along the second direction, the first sidewalls enclose the accommodating cavity DPG, preventing foreign matter, etc., from entering the accommodating cavity DPG from either side (either side in the second direction).

[0081] It is understandable that the bottom plate CA3 may also have other side walls, or support columns for supporting between the top plate and the bottom plate CA3, etc., and the present disclosure does not make any special limitation on this.

[0082] Of course, it is understandable that in other embodiments of the present disclosure, the accommodating chamber DPG may also be opened on the bottom plate CA3, and the carrier platform CA1 may serve as a top plate to cover the accommodating chamber DPG. In this case, the side wall between the top plate and the bottom plate CA3 may be located on the bottom plate CA3. Alternatively, the accommodating chamber DPG may include a first accommodating chamber opened on the carrier platform CA1 and a second accommodating chamber opened on the bottom plate CA3; the first accommodating chamber and the second accommodating chamber have openings opposite to and connected to each other, and together constitute a accommodating chamber DPG for accommodating at least part of the structure of the negative pressure assembly DP.

[0083] In one embodiment of the present disclosure, referring to FIG7 , the negative pressure assembly DP includes an air chamber structure DPA and a negative pressure control member DPB, wherein the air chamber structure DPA has an air chamber with a variable capacity; the negative pressure control member DPB is used to control the capacity change of the air chamber to control whether negative pressure is generated. The air chamber is connected to the suction nozzle NOZ. Exemplarily, the negative pressure control member DPB can squeeze the air chamber structure DPA or stretch the air chamber structure DPA to achieve control of the capacity of the air chamber; for example, the negative pressure control member DPB can squeeze the air chamber structure DPA or stretch the air chamber structure DPA along a first direction. It can be understood that when the suction nozzle connected to the air chamber is blocked, if the capacity of the air chamber increases, the air pressure in the air chamber will drop.

[0084] Optionally, each air chamber structure DPA is disposed in the accommodating cavity DPG to ensure the stability of the air chamber structure DPA and the neat appearance of the carrying platform CA.

[0085] Optionally, the negative pressure control member DPB may be partially located outside the accommodating cavity DPG and connected to the air chamber structure DPA. In this way, an operator may control the air chamber structure DPA outside the carrying platform CA.

[0086] In one embodiment of the present disclosure, the air chamber structure DPA is elastic; the negative pressure control member DPB is used to compress the air chamber structure DPA to compress the air chamber; the compressed air chamber structure DPA can cause the compressed air chamber to rebound during the rebound process, thereby generating negative pressure in the air chamber. In this way, when negative pressure is needed to be applied to the suction nozzle NOZ, the negative pressure control member DPB can compress the air chamber structure DPA and then release the negative pressure control member DPB. At this time, due to the elasticity of the air chamber structure DPA, the air chamber structure DPA rebounds, causing the compressed air chamber to rebound. This rebound causes the air chamber volume to expand, thereby generating negative pressure within the air chamber. If the display module MDL is located at the suction nozzle NOZ, the display module MDL will block the suction nozzle NOZ and be sucked into the suction nozzle NOZ. In this case, the negative pressure in the air chamber connected to the suction nozzle can be maintained. When the negative pressure control member DPB compresses the air chamber structure DPA again, it can compress the air chamber, thereby eliminating the negative pressure at the suction nozzle NOZ, thereby releasing the display module MDL.

[0087] In one embodiment of the present disclosure, the air chamber structure DPA includes an elastic hollow sphere DPA1 (as shown in FIG8 ), an elastic airbag, a resilient box DPA2 (as shown in FIG11 ), or a resilient cylinder, or may be another elastic air chamber structure DPA. The elasticity of the air chamber structure DPA may be derived from the elasticity of the material of the air chamber wall, or an additional elastic member DPA22 may be provided in the air chamber structure DPA to provide the elasticity required for air chamber rebound.

[0088] For example, the material of the elastic hollow ball DPA1 and the elastic airbag (ie, the material of the air chamber wall) may be one or more of elastic silicone, elastic rubber, or elastic plastic, or may be other elastic materials.

[0089] In one example, referring to FIG8 , the air chamber structure DPA is an elastic hollow ball DPA1. The material of the elastic hollow ball DPA1 is elastic silicone, and the cavity of the elastic hollow ball DPA1 is connected to the suction nozzle NOZ as an air chamber. Referring to FIG9 , when the elastic hollow ball DPA1 is squeezed by the negative pressure control part DPB, the volume of the elastic hollow ball DPA1 shrinks, causing its air chamber to shrink and discharge some of the air therein. When the negative pressure control part DPB is released (the negative pressure control part DPB is no longer squeezed to squeeze the elastic hollow ball DPA1), the elastic hollow ball DPA1 has a rebound tendency under the action of the elastic force, that is, the air chamber has an expansion tendency. During the rebound process of the elastic hollow ball DPA1, if the suction nozzle NOZ contacts the display module MDL, the suction nozzle NOZ will be blocked by the display module MDL, causing the inside of the hollow ball to generate and maintain negative pressure, thereby causing the suction nozzle NOZ to adsorb the display module MDL. It is understood that when the suction nozzle NOZ is attached to the display module MDL, the elastic hollow ball DPA1 can fully or partially rebound, so that a negative pressure is generated and maintained in the air chamber. It is understood that if the suction nozzle NOZ is not in contact with the display module MDL, the elastic hollow ball DPA1 will draw air through the suction nozzle NOZ during the rebound process under the action of the negative pressure, thereby rapidly reducing the negative pressure in the air chamber to zero; accordingly, the suction nozzle NOZ will not attach to the display module MDL.

[0090] For another example, referring to Figure 11, the resilient box DPA2 includes a box DPA21 (for example, a flexible box DPA21 or a foldable box DPA21), and an elastic member DPA22 located inside the box DPA21; the internal space of the box DPA21 serves as an air chamber and is connected to the suction nozzle NOZ. Referring to Figure 12, when the negative pressure control member DPB compresses the box DPA21, the elastic member DPA22 is deformed and a rebound force is generated. During this compression process, the volume of the box DPA21 shrinks, causing its air chamber to shrink and expel some of the air therein. When the negative pressure control member DPB is released (the negative pressure control member DPB no longer squeezes the box DPA21), the elastic member DPA22 rebounds, causing the air chamber to expand, that is, the box DPA21 rebounds under the rebound force of the elastic member DPA22. In this way, negative pressure is generated in the air chamber and provided to the suction nozzle NOZ. During the rebound process of the cabinet DPA21, if the suction nozzle NOZ contacts the display module MDL, the suction nozzle NOZ will be blocked by the display module MDL, causing negative pressure to be generated and maintained inside the cabinet DPA21, thereby causing the suction nozzle NOZ to adsorb the display module MDL. It is understandable that when the suction nozzle NOZ adsorbs the display module MDL, the cabinet DPA21 can rebound completely or partially, so that negative pressure is present and maintained in the air chamber. It is understandable that if the suction nozzle NOZ does not contact the display module MDL, the cabinet DPA21 will inhale air from the suction nozzle NOZ under the action of negative pressure during the rebound process, thereby causing the negative pressure in the air chamber to be rapidly weakened to disappear; accordingly, the suction nozzle NOZ will not adsorb the display module MDL. In this embodiment, the reboundable cabinet DPA2 uses the elasticity of the elastic part to achieve rebound, which can ensure the rebound effect and improve the life of the reboundable cabinet DPA2.

[0091] In one example, the elastic member DPA22 within the resilient housing DPA2 can be a compression spring. When compressed, the compression spring can provide a rebound force. Furthermore, the compression spring extends in a direction that aligns with the deformation direction of the housing DPA21; for example, the compression spring extends in a first direction.

[0092] In one example, the foldable enclosure DPA21 may be an accordion enclosure DPA21.

[0093] For another example, a resilient cylinder includes a cylinder body, a piston, and an elastic member. An air chamber is defined between the cylinder body and the piston, and the elastic member is disposed within the air chamber. When the negative pressure control member compresses the cylinder, for example, by applying extrusion forces in opposite directions to the cylinder body and the piston, the piston and the cylinder body slide relative to each other, compressing the air chamber and thereby expelling some of the air in the air chamber. During this process, the elastic member deforms and generates a rebound force. When the negative pressure control member is released, the elastic member rebounds and pushes the piston or cylinder, causing the air chamber to rebound and expand.

[0094] It can be understood that in each of the above examples, the negative pressure component DP and the way of generating negative pressure are exemplified by taking the example of the negative pressure control component DPB compressing the air chamber structure DPA and then expanding the air chamber. In the above examples, the negative pressure control component DPB compresses the air chamber structure DPA, and then compresses the air chamber to discharge some of the air in the air chamber. When external force is no longer applied to the negative pressure control component DPB, the air chamber structure DPA expands the air chamber under the action of the rebound force, and generates negative pressure during the expansion of the air chamber. In these examples, when negative pressure is needed, the operator only needs to squeeze the air chamber structure DPA through the negative pressure control component DPB, and then stop controlling the negative pressure control component DPB. There is no need to lock or tighten the negative pressure control component DPB, etc., which has the advantage of simple operation.

[0095] In other embodiments of the present disclosure, negative pressure can also be generated by expanding the air chamber structure DPA using the negative pressure control component DPB. For example, the negative pressure control component DPB can stretch the air chamber structure DPA to expand the air chamber, thereby generating negative pressure in the air chamber. At this time, if the suction nozzle NOZ contacts the display module MDL, the display module MDL will block the suction nozzle NOZ and cause the display module MDL to be adsorbed under negative pressure; the negative pressure control component DPB can be locked by the locking component to prevent the negative pressure control component DPB from rebounding and causing the air chamber to rebound, thereby maintaining negative pressure in the air chamber. When the air chamber structure DPA retracts and causes the air chamber to retract, for example, the negative pressure control component DPB is released and causes the air chamber structure DPA to retract under the action of its own rebound force, or an external force controls the negative pressure control component DPB to squeeze the air chamber structure DPA and causes the air chamber structure DPA to retract, the negative pressure in the air chamber can disappear and the adsorbed display module MDL can be released.

[0096] In one embodiment of the present disclosure, referring to FIG7 , the number of the air chamber structures DPA is multiple and corresponds one-to-one to the multiple suction nozzles NOZ, and any one of the air chamber structures DPA is used to provide negative pressure to the corresponding suction nozzle NOZ. In this way, the air chamber structure DPA and the suction nozzle NOZ that provide negative pressure are set one-to-one, which can ensure the stability of adsorption and reduce the risk of adsorption failure. When the adsorption of any suction nozzle NOZ fails, only the negative pressure in the air chamber structure DPA corresponding to the suction nozzle NOZ will be dissipated, without affecting other air chamber structures DPA, thereby avoiding affecting the adsorption of the display module MDL by other suction nozzles NOZ.

[0097] In one embodiment of the present disclosure, the negative pressure control member DPB includes a push rod, which is used to compress or expand the air chamber of the air chamber structure DPA. By pulling or pushing the push rod, the compression or expansion of the air chamber structure DPA can be achieved. It can be understood that the compression or expansion of the air chamber structure DPA is not necessarily caused by the movement of the push rod. For example, when the compressed air chamber structure DPA rebounds and expands under the action of a rebound force, the source of power for the expansion may be the rebound force of the air chamber structure DPA itself rather than the pulling force of the push rod. In some cases, the push rod can also act as a follower and be pushed as the air chamber structure DPA expands. For another example, when the expanded air chamber structure DPA rebounds and contracts under the action of a rebound force, the source of power for the contraction may be the rebound force of the air chamber structure DPA itself rather than the pushing force of the push rod. In some cases, the push rod can also act as a follower and be pulled as the air chamber structure DPA contracts.

[0098] In one embodiment of the present disclosure, referring to Figures 10 and 13, the push rod includes a first push rod DPB1 and a second push rod DPB2 that cooperate with each other; the first push rod DPB1 is used to apply a first extrusion force to the air chamber structure DPA, and the second push rod DPB2 is used to apply a second extrusion force to the air chamber structure DPA. The first extrusion force and the second extrusion force are of the same magnitude and in opposite directions, for example, both are along the first direction. In this way, the air chamber structure DPA can be compressed under the extrusion of the first push rod DPB1 and the second push rod DPB2. In one example, since the air chamber structure DPA is squeezed on both sides of the first direction at the same time, the air chamber structure DPA can exhibit a centripetal contraction characteristic. This is conducive to maintaining the stability of the center of the air chamber, and further helps to maintain a relatively stable positional relationship between the air chamber structure DPA and the suction nozzle NOZ, avoiding uneven force on the air chamber structure DPA and center displacement, and further avoiding the displacement affecting the suction nozzle NOZ and causing damage to the adsorbed display module MDL.

[0099] Of course, in another embodiment of the present disclosure, there is no need to set up two push rods that cooperate with each other, but instead a push rod is used to achieve compression of the air chamber structure DPA. Specifically, a blocking member can be set to block the air chamber structure DPA to prevent the air chamber structure DPA from shifting under the push of the push rod, or a fixing member can be set to fix the air chamber structure DPA. In this way, when the push rod squeezes the air chamber structure DPA, the air chamber structure DPA is not displaced but compressed. For example, a blocking member (such as a baffle pre-fixed on the top plate or bottom plate CA3) is provided on one side of the air chamber structure DPA, and the push rod is used to apply an extrusion force to the other side of the air chamber structure DPA. In this way, under the joint extrusion of the blocking member and the push-pull rod, the air chamber structure DPA can be squeezed and exhausted.

[0100] In one embodiment of the present disclosure, referring to Figures 10 and 13 , there are multiple air chamber structures DPA, and the negative pressure control member controls each air chamber structure DPA simultaneously.

[0101] For example, the push rod includes a handle, a main rod body DPBB and a plurality of transmission mechanisms DPBA; the handle is provided at the end of the main body and is located outside the carrying platform; the plurality of transmission mechanisms DPBA are connected to the main rod body DPBB and are connected one-to-one with each of the air chamber structures DPA. In this way, the operator can push or pull the main rod body DPBB through the handle, and the main rod body DPBB drives the transmission mechanism DPBA, so that each transmission mechanism DPBA simultaneously applies a force to each air chamber structure DPA, such as applying an extrusion force or an expansion force. In this embodiment, the transmission mechanism DPBA is connected to the air chamber structure DPA, which can be connected through a hinge or a flexible joint so that the transmission mechanism DPBA and the air chamber structure DPA become a whole, or the air chamber structure DPA and the transmission mechanism DPBA are in contact with each other (for example, abutting). In one example, the transmission mechanism DPBA can be a side branch rod body, a side plate, a lever mechanism or other structure that can apply a force to the air chamber structure DPA according to the movement of the main rod body DPBB.

[0102] In the examples of Figures 10 and 13, thick black arcs are used to indicate that the main rod body DPBB of one push rod and the transmission mechanism DPBA of the other push rod do not interfere with each other. For example, the two push rods can be arranged at different heights to avoid each other, or the main rod body DPBB of one push rod and the transmission mechanism DPBA of the other push rod can be arranged at different heights, or the bamboo rod of one push rod can be bent to avoid the transmission mechanism DPBA of the other push rod, or the transmission mechanism DPBA of one push rod can be provided with a through hole to allow the main rod body DPBB of the other push rod to pass through, etc.

[0103] In other embodiments of the present disclosure, the negative pressure assembly may include a negative pressure pump assembly and a control switch assembly; under the control of the control switch assembly, the negative pressure pump assembly is capable of providing negative pressure to the suction nozzles. It is understood that the negative pressure pump assembly may include one or multiple negative pressure pumps. The control switch assembly may include one or multiple control switches. In one embodiment of the present disclosure, the negative pressure pump assembly includes a negative pressure module and a negative pressure control valve corresponding to each suction nozzle; the negative pressure module includes one or more negative pressure pumps for generating negative pressure. The suction nozzles are connected to the negative pressure module via corresponding negative pressure control valves. The control switch assembly is used to control the opening or closing of each negative pressure control valve, or the degree of opening of each negative pressure control valve, thereby controlling whether the negative pressure pump assembly provides negative pressure to the suction nozzles. In this embodiment, the negative pressure module may include one negative pressure pump, or multiple negative pressure pumps connected in parallel or in series, so that the negative pressure pumps can provide negative pressure to the negative pressure control valves. Of course, if necessary, the negative pressure module may also include other structures, for example, the negative pressure module may also include a buffer chamber, the suction port of each negative pressure pump is connected to the buffer chamber, and each negative pressure control valve is connected to the buffer chamber. In this embodiment, when a suction nozzle requires negative pressure, the negative pressure control valve corresponding to the suction nozzle can be opened by controlling the switch group, or the opening of the negative pressure control valve can be controlled, thereby enabling the negative pressure module to provide negative pressure to the suction nozzle.

[0104] In one example, when the suction nozzle requires negative pressure, the control switch group can make the negative pressure control valve corresponding to the suction nozzle continuously conductive, so that the negative pressure module continuously provides negative pressure for the suction nozzle, reducing the risk of failure of the suction nozzle.

[0105] In another example, when the suction nozzle requires negative pressure, the control switch group can turn on the negative pressure control valve corresponding to the suction nozzle, and close the negative pressure control valve after the suction nozzle obtains negative pressure. At this time, the display module blocks the suction nozzle, thereby maintaining the negative pressure in the suction nozzle. For example, the control switch group can turn on the negative pressure control valve and then turn it off after a preset time, for example, the negative pressure control valve is turned on and then turned off after 1 to 3 seconds. For another example, the negative pressure component can also be provided with a pressure sensor for monitoring the negative pressure in the suction nozzle. After the control switch group turns on the negative pressure control valve, the corresponding negative pressure in the suction nozzle can also be obtained according to the pressure sensor. After the negative pressure in the suction nozzle reaches the expected negative pressure, the control switch group can control the negative pressure control valve to close.

[0106] In one example, the control switch group may include control switches corresponding to each negative pressure control valve one by one, and these control switches may include one or more mechanical switches such as button switches and touch switches, or electronic switches.

[0107] In another example, the control switch group may include a remote control module; the remote control module can obtain and execute control instructions for each negative pressure control valve through Bluetooth, WIFI, NFC or other wireless communication methods, thereby controlling the conduction or closing of each negative pressure control valve, or controlling the opening of the negative pressure control valve.

[0108] In one example, the negative pressure module may further include a negative pressure release valve; the control switch group is further configured to control the opening or closing of the negative pressure release valve. When the display module needs to be released, the negative pressure release valve can be opened, and the negative pressure control valve corresponding to the suction nozzle with negative pressure can be opened, thereby releasing the negative pressure in the suction nozzle and, in turn, releasing the display module. Of course, in other examples of the present disclosure, a negative pressure release valve may not be provided, and other methods may be used to achieve a controlled release of the negative pressure in the suction nozzle.

[0109] It can be understood that the above description of the negative pressure module, negative pressure control valve, and control switch group is merely an exemplary description; the negative pressure module, negative pressure control valve, and control switch group in this embodiment are not limited to the above examples.

[0110] In another embodiment of the present disclosure, the negative pressure pump assembly may include multiple negative pressure pumps corresponding to each suction nozzle, and the negative pressure pumps are connected to the corresponding suction nozzles. The control switch assembly controls whether each negative pressure pump is turned on or off, thereby controlling whether each suction nozzle can obtain the negative pressure provided by the negative pressure pump. When a suction nozzle requires negative pressure, the control switch assembly can control the negative pressure pump corresponding to the suction nozzle to operate, thereby providing the required negative pressure to the suction nozzle.

[0111] In one example, the control switch group may include control switches corresponding to each negative pressure pump one by one, and these control switches may include one or more mechanical switches such as button switches and touch switches, or electronic switches.

[0112] In another example, the control switch group may include a remote control module; this remote control module can obtain and execute control instructions for each negative pressure pump via Bluetooth, Wi-Fi, NFC, or other wireless communication methods, thereby controlling which negative pressure pumps are active. In one embodiment of the present disclosure, referring to Figures 14 and 15 , the suction nozzle NOZ is a retractable suction nozzle NOZ. In a first state, referring to Figure 14 , the suction nozzle NOZ is retracted within the suction nozzle cavity and cannot contact the display module MDL; in this state, the suction nozzle NOZ cannot absorb the display module MDL. In a second state, referring to Figure 15 , the suction nozzle NOZ extends from the suction nozzle cavity; in this state, the suction nozzle NOZ can contact the display module MDL and absorb the display module MDL. In this way, by controlling which suction nozzles NOZ are in the first state and which are in the second state, the number and distribution of suction nozzles NOZ used to absorb the display module MDL can be controlled to accommodate the absorption requirements of different display modules MDL. This significantly improves the versatility of the carrier CA for display modules MDLs of various shapes and sizes.

[0113] For example, in the example of Figure 16, the display module MDL is a structure with protrusions on both sides, so the suction nozzles NOZ located on both sides can be pulled out and placed in the second state, and the suction nozzle NOZ located in the middle can be compressed and placed in the first state. In this way, the display module MDL can be adsorbed at the protrusions, which can ensure the stability of the display module MDL after adsorption. For another example, in the example of Figure 17, the display module MDL is a structure with a protrusion in the middle, so the suction nozzle NOZ located in the middle can be pulled out and placed in the second state, and the suction nozzles NOZ located on both sides can be compressed and placed in the first state. In this way, the display module MDL can be adsorbed at the protrusions, which can ensure the stability of the display module MDL after adsorption.

[0114] Therefore, in this embodiment, by arranging a plurality of retractable suction nozzles NOZ on the carrier platform CA1, the suction nozzles NOZ can adjust their own states according to the structural characteristics of the display module MDL, thereby achieving the optimal adsorption effect and improving the stability of the display module MDL after adsorption.

[0115] In one embodiment of the present disclosure, referring to FIG19 , the carrier CA includes a plurality of suction nozzles NOZ distributed in an array, for example, M*N suction nozzles NOZ distributed in an array, and these suction nozzles NOZ are arranged in M ​​rows and N columns. Wherein, M and N are positive integers not less than 2. In the embodiment of the present disclosure, the first direction DH is used as the row direction, and the second direction DV is used as the column direction. In other words, the suction nozzle row includes a plurality of suction nozzles NOZ arranged in sequence along the second direction; the suction nozzle column includes a plurality of suction nozzles NOZ arranged in sequence along the first direction.

[0116] Optionally, multiple suction nozzles NOZ are densely arranged, for example, the spacing between two adjacent suction nozzles NOZ is not more than 25 mm. In this way, the carrying platform CA is provided with multiple densely distributed suction nozzles NOZ, so that the carrying platform CA can be suitable for display modules MDL of various shapes. According to the shape of the display module MDL, some of the suction nozzles NOZ can be extended out of the suction nozzle cavity and serve as action suction nozzles NOZ (in the second state), and these action suction nozzles NOZ can be adapted to the back of the display module MDL to adsorb the display module MDL. The remaining suction nozzles NOZ (in the first state) are in the suction nozzle cavity and do not participate in the adsorption of the display module MDL.

[0117] For example, in the example of Figure 19, the carrier CA is provided with three nozzle rows, each of which has six nozzles NOZ. It is understood that as the carrier CA1 of the carrier CA is larger, more nozzle rows are provided, and the number of nozzles in each nozzle row is greater.

[0118] Of course, in another embodiment of the present disclosure, the carrier CA can be provided with suction nozzles NOZ arranged at a lower density and in a regular pattern, for example, the spacing between adjacent suction nozzles NOZ is not less than 35 mm. In this way, the carrier CA can be suitable for adsorbing the flat display module MDL.

[0119] In one example, referring to FIG20 , a plurality of nozzle rows (e.g., two nozzle rows) are provided on the carrier CA, and each nozzle row includes a plurality of nozzles NOZ, e.g., 2 to 8 nozzles NOZ (e.g., four). Of course, it is understood that, as the size of the carrier platform CA1 of the carrier CA becomes larger, more nozzle rows are provided, and the number of nozzles in each nozzle row becomes greater.

[0120] In some other embodiments of the present disclosure, the suction nozzles NOZ on the carrying platform CA may be arranged irregularly to accommodate the special-shaped display module MDL.

[0121] In one example, as shown in Figure 21, along the second direction DV, the carrier platform CA1 is divided into three areas: a first area XA, a second area XB, and a third area XC. The width of the nozzle rows in the first and third areas XA and XC is greater than the width of the nozzle rows in the second area XB. No nozzles NOZ are provided at either end of the second area XB. This carrier platform CA is therefore suitable for use with a C-type concave-convex display module MDL.

[0122] In one example, referring to FIG22 , along the second direction DV, the carrier CA1 is divided into three areas: a first area XA, a second area XB, and a third area XC. In the first area XA and the third area XC, the nozzle row includes a plurality of nozzles NOZ arranged in sequence at equal intervals. A nozzle row may also be provided in the second area XB, but no nozzles are provided in the middle part of the second area XB. In other words, no nozzles may be provided in the middle area of ​​the carrier CA1. In this way, the carrier CA can be suitable for adsorption and fixation of asymmetric display modules MDL such as S-shaped ones.

[0123] In one example, as shown in Figure 23 , the carrier platform CA1 includes, along the first direction DH, a fourth area YA, a fifth area YB, and a sixth area YC. Nozzle rows are provided in the fourth and sixth areas YA and YC, each including a plurality of nozzles arranged at equal intervals along the second direction DV. No nozzles NOZ are provided in the fifth area YB. This allows the carrier platform CA to be suitable for display modules MDL having a uniquely shaped center portion.

[0124] In one example, referring to FIG24 , along the second direction DV, the carrier CA1 is divided into three areas, namely the first area XA, the second area XB and the third area XC. Rows of suction nozzles are provided in the first area XA, the second area XB and the third area XC. Among them, the row of suction nozzles located in the second area XB includes a plurality of suction nozzles arranged at equal intervals. The row of suction nozzles located in the first area XA and the row of suction nozzles located in the third area XC are the same width as the row of suction nozzles in the second area XB; however, the row of suction nozzles located in the first area XA and the row of suction nozzles located in the third area XC do not have suction nozzles in the middle area of ​​the first area XA and the middle area of ​​the third area XC. In this way, the carrier CA can be suitable for a display module MDL with three asymmetric sections (for example, the far, middle and near sections) of the display module MDL.

[0125] In some embodiments of the present disclosure, see Figures 19 to 22 , the suction nozzle NOZ may be a circular nozzle. Of course, as needed, see Figures 23 to 24 , other shapes of suction nozzles may also be provided, such as an elliptical nozzle or a regular polygonal nozzle (e.g., a square nozzle, a regular hexagonal nozzle, etc.).

[0126] In one embodiment of the present disclosure, referring to FIG18 , a flexible positioning member CA5 may be attached to the supporting surface of the supporting platform CA1. The flexible positioning member is removably adhered to the surface of the supporting platform CA1; the flexible positioning member is configured to engage with the edge of the display module to position the display module. For example, flexible positioning members CA5 are provided on both sides of the display module in a first direction to facilitate positioning of the display module, thereby improving both the stability of the display module fixed to the supporting platform and the accuracy of the positioning of the display module on the supporting platform.

[0127] In this embodiment, when the carrying platform CA needs to carry a new display module, the position of the flexible positioning member CA5 can be adjusted according to the new display module, thereby enabling the carrying platform CA to adapt to different display modules.

[0128] In this embodiment, the flexible positioning member CA5 is flexible, so it can avoid quality damage to the edge of the display module and can play a certain buffering effect, which is conducive to maintaining the quality of the display module.

[0129] In one example, the flexible positioning member may be made of foam, such as a foam block or a foam strip. Foam has good compression capability, can more firmly position the edge of the display module and provide a better cushioning effect.

[0130] In one embodiment of the present disclosure, referring to Figures 1 to 3 , the carrying platform CA may further include a connecting portion CA4 located at an end of the carrying platform CA1 away from the crimping platform CA2. When the carrying platform CA is connected to the base BA, a fixing mechanism BA1 on the base BA can connect with the connecting portion CA4 to secure the connecting portion CA4.

[0131] Of course, it is understood that the fixing mechanism BA1 on the base BA can also be fixed to other parts of the carrier CA. For example, referring to Figure 4, when the carrier CA is connected to the base BA, the fixing mechanism BA1 on the base BA is fixed to the crimping platform CA2 and the connecting portion CA4 to further enhance the stability of the fixation.

[0132] In one example, the crimping platform CA2 and the connecting part CA4 are both provided with a crimping groove CAP at the edge; the fixing mechanism BA1 has a grabbing clamp, which can extend into the crimping groove CAP to grab (for example, press or clamp) the carrying platform CA to achieve fixation of the carrying platform CA.

[0133] In one example, the fixing mechanism BA1 further includes a cylinder mechanism, which is used to control the clamping.

[0134] In an example, the crimping platform CA2 is provided with two crimping grooves CAP, which are respectively located at two opposite edges of the crimping platform CA2. Specifically, the two crimping grooves CAP are respectively located at two sides of the crimping platform CA2 in the second direction.

[0135] In one example, the connection portion CA4 is provided with two crimping grooves CAP, which are respectively located at two opposite edges of the connection portion CA4. Specifically, the two crimping grooves CAP are respectively located at both sides of the second direction of the connection portion CA4.

[0136] In one embodiment of the present disclosure, the carrier CA is further provided with a positioning hole CAH extending along a third direction through the carrier CA. The base BA is provided with a positioning post BA2 configured to engage with the positioning hole CAH. When the carrier CA is secured to the base BA, the positioning post BA2 is inserted into the positioning hole CAH to position the carrier CA.

[0137] In one embodiment of the present disclosure, the fixing mechanism BA1 and the positioning column BA2, which are used with the same carrier CA, are collectively referred to as a set of positioning connection components. The base BA is provided with multiple sets of positioning connection components, each of which can be used with a carrier CA of a certain size. Different sets of positioning connection components can be used with carrier CAs of different sizes. In this way, the base BA can be adapted to a variety of different carrier CAs, thereby improving the versatility of the inspection equipment.

[0138] For example, in the base BA shown in Figure 6 , the base BA is equipped with two sets of positioning and connection assemblies, each of which includes multiple positioning posts BA2 and four fixing mechanisms BA1. The first positioning and connection assembly accommodates a smaller load platform CA than the second positioning and connection assembly. In the example shown in Figure 4 , the load platform CA and the second positioning and connection assembly cooperate to secure the load platform CA to the base BA.

[0139] In one embodiment of the present disclosure, a push rod hole HA for the push rod to pass through can be provided on the side of the connecting part CA4 (the side on the first direction side), the main rod body DPBB of the push rod passes through the push rod hole HA, and the handle is provided on the outside of the connecting part CA4.

[0140] Of course, when the negative pressure control member DPB includes two mutually cooperating push rods, a push rod hole HA for the push rod to pass through can also be provided on the side of the pressing platform CA2 (the side facing the first direction), with the main push rod body DPBB passing through the push rod hole HA, and a handle provided on the outside of the pressing platform CA2. In this way, the carrying platform includes two handles arranged opposite each other along the first direction, and the display module can be attracted and released by controlling the two handles.

[0141] In one embodiment of the present disclosure, the connection portion CA4 and the carrying platform CA1 are located on the same side of the bottom plate CA3, for example, both are located above the bottom plate. Furthermore, the connection portion CA4 and the carrying platform CA1 can be an integrally formed structure.

[0142] In one embodiment of the present disclosure, referring to FIG2 , the carrying platform CA is provided with a prism avoidance cavity CAG on both sides of the carrying platform CA1 in the second direction; at least a portion of the base BA cooperating with the carrying platform CA is provided with a prism assembly BA3; the prism assembly BA3 can be accommodated in the prism avoidance cavity CAG to detect the side of the display module MDL. With the help of the refraction and / or reflection of light by the prism assembly BA3, the detection equipment can detect the edge position of the display module MDL, especially the side of a large-angle screen or a special-shaped screen. Furthermore, the prism assembly BA3 has an angle adjustment mechanism and a prism, and the angle adjustment mechanism can adjust the angle of the prism.

[0143] In one embodiment of the present disclosure, the base plate CA3 of the carrier CA is an integrated structure. A gap may be provided between the crimping platform CA2 and the connecting portion CA4 to reduce the consumables and weight of the crimping platform CA2 and the connecting portion CA4 while maintaining the structural strength of the carrier CA, thereby reducing the cost of the carrier CA.

[0144] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the invention disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.
