Description

Technical Field

[0001] This application relates to the field of backlight transfer technology, and more particularly to a backlight transfer mechanism. Background Technology

[0002] Backlight components need to be moved and positioned across workstations on the module assembly line. These components are thin and brittle, with surfaces covered by optical films or light guide plates, allowing for minimal surface indentations and contamination. Furthermore, production lines often involve mixed production of multiple specifications, requiring the transfer equipment to be compatible with backlights of different lengths, widths, and areas while maintaining stable cycle time without stopping the line for changes.

[0003] Existing transfer mechanisms typically employ a single-axis linear mechanism along the production line direction for lateral drive, coupled with a vertical lifting mechanism to complete the pick-and-place action. The suction unit usually consists of several fixed arrays of disc-shaped suction cups connected in parallel to a unified negative pressure source for overall start-up and shutdown. Different specifications can be adapted by changing the suction cup arrangement or fixtures when necessary. Some devices utilize single-camera detection for positioning, but suction cup start-up and shutdown are still primarily controlled by the entire unit.

[0004] However, the suction cups in the existing transfer mechanism are fixedly arranged and uniformly ventilated, making it impossible to selectively activate the corresponding suction points based on the length, width and area of ​​the backlight. This results in excessive suction distribution for small parts and insufficient support for large parts, requiring the replacement of fixtures for adaptation, which leads to long line change times and affects transfer efficiency. Utility Model Content

[0005] In view of this, it is necessary to provide a transfer mechanism that can adaptively adsorb backlights in order to solve the above problems.

[0021] An embodiment of this application provides a backlight transfer mechanism, including a base, a propulsion device, and a transfer mechanism. The propulsion device includes a first propulsion component and a second propulsion component disposed on the first propulsion component. The first propulsion component is disposed on the base and is movable along a first direction. The second propulsion component is located on the side of the first propulsion component away from the base and moves along a second direction perpendicular to the first direction. The transfer component includes a carrier and a plurality of transfer components. The carrier is disposed on the side of the second propulsion component away from the first propulsion component, and the plurality of transfer components are arranged in a ring around the carrier for moving the backlight. The transfer mechanism further includes an identification component disposed on the carrier and electrically connected to each of the transfer components. The identification component identifies the backlight in the direction in which the transfer component is positioned, thereby controlling the corresponding transfer component to grasp the backlight.

[0022] The aforementioned backlight transfer mechanism utilizes multiple transfer components arranged in a ring along a carrier, allowing for flexible combination and operation based on the size and shape of the backlight, achieving multi-point or localized adsorption. The identification component not only detects the backlight's position but also identifies its shape and placement, thus determining its specifications and type. Based on the identification results, the system automatically activates the corresponding transfer component to perform the adsorption operation, achieving intelligent grasping according to shape matching. The dual-propulsion component provides a smooth composite displacement path, and the collaborative work of the identification component and the ring-shaped transfer components ensures a smooth transfer process with high repeatability. This overall structure reduces uneven stress on the backlight during transfer, achieving low-damage grasping and efficient transport of the backlight.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] Please see Figures 1-5This application provides a backlight transfer mechanism 1000, including a base 10, a propulsion device 20, and a transfer mechanism. The propulsion device 20 includes a first propulsion component 21 and a second propulsion component 22 disposed on the first propulsion component 21. The first propulsion component 21 is disposed on the base 10 and is movable along a first direction. The second propulsion component 22 is located on the side of the first propulsion component 21 away from the base 10 and moves along a second direction perpendicular to the first direction. The transfer component 30 includes a support member 31 and a plurality of transfer members 32. The support member 31 is disposed on the side of the second propulsion component 22 away from the first propulsion component 21, and the plurality of transfer members 32 are arranged around the support member 31 for moving the backlight. The transfer mechanism further includes an identification component 40, which is disposed on the support member 31 and electrically connected to each of the transfer members 32. The identification component 40 identifies the backlight in the direction in which the transfer member 32 is positioned, so as to control the corresponding transfer member 32 to grasp the backlight.

[0025] Specifically, in this embodiment, it should be noted that the backlight transfer mechanism 1000 is provided with a base 10 as an installation and positioning reference; the propulsion device 20 includes a first propulsion component 21 and a second propulsion component 22 that are orthogonal to each other, wherein the first propulsion component 21 is mounted on the base 10 and moves along a first direction, and the second propulsion component 22 is disposed on the side of the first propulsion component 21 away from the base 10 and moves along a second direction perpendicular to the first direction, thereby forming a two-dimensional linear positioning degree of freedom in the same plane.

[0026] Furthermore, the transfer assembly 30 includes a carrier 31 and a plurality of transfer members 32 arranged circumferentially around the carrier 31. The carrier 31 is fixed on the second propulsion assembly 22 and located on the side opposite to the first propulsion assembly 21. The plurality of transfer members 32 face the backlight to be transported to perform gripping and releasing actions.

[0027] Furthermore, the identification component 40 is fixed on the carrier 31, arranged in the direction of the transfer component 32, and electrically connected to each transfer component 32. It is used to identify the shape and posture of the backlight and generate corresponding control signals to selectively trigger the corresponding transfer component 32 to perform grasping or releasing.

[0028] In summary, the above structural arrangement allows end-effector recognition and end-effector execution to be located on the same end actuator, shortening the link between perception and execution. At the same time, the two-dimensional propulsion provides the carrier 31 with precise in-plane alignment between pick-up and drop positions, and the ring-shaped transfer components 32 can be combined and activated as needed to match backlights with different boundary sizes and prioritize force support in the surrounding area.

[0029] In one specific embodiment, the transfer component 30 further includes a plurality of negative pressure components 33 disposed on the carrier 31, each of the negative pressure components 33 being connected to each of the transfer components 32 to individually control the gripping or releasing of each of the transfer components 32.

[0030] Specifically, in this embodiment, it should be noted that the transfer assembly 30 further includes a plurality of negative pressure assemblies 33 disposed on the support member 31. The plurality of negative pressure assemblies 33 are distributed circumferentially along the support member 31 and are respectively disposed corresponding to each transfer member 32. Each negative pressure assembly 33 is connected to the corresponding transfer member 32 through its own negative pressure channel, and each air passage is isolated from each other within the support member 31.

[0031] Furthermore, the control system issues opening and closing commands to each negative pressure component 33 to independently control the gripping or releasing action of the corresponding transfer component 32; the unselected negative pressure component 33 remains closed, and the selected negative pressure component 33 opens according to a preset sequence to complete the pick-up and drop. By directly arranging the negative pressure component 33 on the carrier component 31, the length of the negative pressure channel and the volume of the air chamber are reduced, thereby shortening the start-stop response time and reducing the pressure drop and hysteresis caused by excessive pipeline length.

[0032] In one specific embodiment, the identification component 40 includes a first camera 41 and a second camera 42 disposed on the side of the carrier 31 opposite to the transfer member 32, with a gap between adjacent two transfer members 32, and the first camera 41 and the second camera 42 respectively located at one of the gaps.

[0033] Specifically, in this embodiment, it should be noted that the identification component 40 includes a first camera 41 and a second camera 42, both disposed on the side of the carrier 31 opposite to the transfer member 32; multiple transfer members 32 are arranged circumferentially around the carrier 31, with gaps formed between adjacent transfer members 32 to allow light to pass through. The first camera 41 and the second camera 42 are respectively arranged at the gaps, so that their imaging optical axes can directly view the backlight source to be transported through the gaps. Since the identification component 40 is located on the side opposite to the carrier 31 and the transfer member 32, the camera body does not mechanically interfere with the adsorption and clamping actions of the transfer member 32.

[0034] Furthermore, the two cameras occupy the gap position respectively, and can obtain two separate fields of view in the same actuator, which are used to identify the backlight outline, positioning reference or accessible area online; the identification result is transmitted to the corresponding transfer member 32 through the electrical connection in the carrier member 31 to realize the start and stop control of the end piece by piece.

[0035] In one specific embodiment, the first camera 41 is disposed in front of the second camera 42 along a first direction, and the first camera 41 is disposed on the side of the carrier 31 near the second propulsion component 22, and the second camera 42 is disposed opposite to the first camera 41.

[0036] In one specific embodiment, the identification component 40 further includes a third camera 43, which is disposed on the carrier 31 and located at the geometric center of the carrier 31, for identifying the backlight.

[0037] Specifically, the first camera 41 is positioned in front of the second camera 42 along a first direction, meaning the two are arranged in a front-to-back configuration on the carrier 31 along the first direction of the production line. The first camera 41 is mounted on the side of the carrier 31 closest to the second push assembly 22, and the second camera 42 is positioned opposite the first camera 41, forming a front-to-back dual field of view on the carrier 31. Both cameras image towards the direction in which the transfer member 32 is positioned, and their imaging optical axes are projected onto the backlight to be transported through the gap between adjacent transfer members 32, thereby avoiding mechanical interference and field-of-view obstruction with the transfer member 32.

[0038] Furthermore, the front-mounted first camera 41 can acquire the shape and posture information of the backlight as the platform moves along the first direction, in order to predict the touchable area and select points; the rear-mounted second camera 42 performs verification and fine alignment during the final approach or arrival stage. Since the first camera 41 is located on the side closer to the second propulsion component 22, its relative cantilever distance with the second direction moving component is shorter, which can effectively reduce the impact of small swaying and structural deformation on imaging stability under high acceleration and deceleration and frequent start and stop conditions.

[0039] In one specific embodiment, the transfer member 32 includes a connecting end 321 and an adsorption end 322 arranged sequentially. The connecting end 321 extends into the carrier member 31 and communicates with the negative pressure component 33. The adsorption end 322 extends along the side away from the connecting end 321. When the adsorption end 322 adsorbs the backlight, the adsorption end 322 retracts toward the side of the connecting end 321 to adsorb the backlight.

[0040] Specifically, in this embodiment, it should be noted that the transfer member 32 includes a connecting end 321 and an adsorption end 322 arranged in sequence. The connecting end 321 extends into the carrier member 31 and communicates with the corresponding negative pressure component 33 to form a negative pressure channel from the inside of the carrier member 31 to the internal cavity of the transfer member 32. The adsorption end 322 extends outward along the side away from the connecting end 321 and is used to contact the backlight surface and establish a seal.

[0041] Furthermore, when the negative pressure component 33 is activated, the pressure inside the adsorption end 322 decreases, causing it to contract and displace along the axial direction of the transfer component 32 toward the connection end 321, thereby maintaining contact with the workpiece surface while forming axial clearance and self-compliant contact.

[0042] In one specific embodiment, the transfer member 32 has a plurality of parallel annular portions 333 formed on the side near the adsorption end 322. Each annular portion 333 has an annular inner cavity, and each annular inner cavity is connected to the negative pressure component 33. When adsorbing the backlight, the opposite ends of each annular portion 333 are compressed inward.

[0043] Specifically, in this embodiment, it should be noted that the transfer member 32 has a plurality of parallel annular portions 333 integrally formed on the side near the adsorption end 322, preferably coaxial concentric rings arranged radially in sequence. Each annular portion 333 has an independent annular cavity inside, and each annular cavity is connected to the negative pressure component 33, so that negative pressure can be established nearby in each annular portion 333.

[0044] Furthermore, when the backlight is adsorbed, under the action of negative pressure, each annular part 333 shortens along its own axis, and its opposite ends contract inward, thereby forming the required pressure and state for adhesion and maintenance in the area close to the backlight. This can adapt to the thickness tolerance and slight warping of the backlight at the moment of grasping, reducing out-of-plane deflection and edge sagging.

[0045] In one specific embodiment, the first propulsion component 21 includes a first slider 211 and a second slider 212. The first slider 211 is disposed on the base 10, and the second slider 212 is disposed on one side of the first slider 211 and connected to the second propulsion component 22 on the other side, for driving the second component to move along a first direction.

[0046] Specifically, in this embodiment, it should be noted that the first propulsion assembly 21 includes a first slider 211 and a second slider 212. The first slider 211 is disposed on the base 10 and is used to provide sliding guidance along the first direction; one side of the second slider 212 is mounted on the first slider 211 and can slide smoothly relative to the first slider 211 in the first direction, and the other side of the second slider 212 is fixedly connected to the second propulsion assembly 22.

[0047] Furthermore, during operation, the control system drives the first propulsion assembly 21, causing the second sliding member 212 to carry the second propulsion assembly 22 in a reciprocating motion in a first direction; the second propulsion assembly 22 maintains a second direction of motion capability orthogonal to the first propulsion assembly 21, thereby forming a planar positioning degree of freedom with the base 10 as the reference. The first sliding member 211 and the second sliding member 212 are in a sliding fit with a suitable fitting clearance to ensure smooth guidance and repeatable positioning under load and acceleration / deceleration conditions; the connection between the second sliding member 212 and the second propulsion assembly 22 is a rigid connection to ensure the synchronization and stability of motion transmission.

[0048] Furthermore, through the sliding cooperation of the first slider 211 and the second slider 212, the second propulsion assembly 22 is provided with independent linear motion in the first direction. The second propulsion assembly 22 is decoupled from the second direction motion of itself, which helps to reduce inter-axis interference and improve in-plane alignment accuracy and repeatability. The second propulsion assembly 22 is directly supported by the second slider 212 and driven in the first direction, which can shorten the force transmission link, reduce motion lag and cumulative error, and improve cycle stability.

[0049] In one specific embodiment, the second propulsion component 22 includes a third slider 221 and a fourth slider 222. The third slider 221 is disposed on the second slider 212, and the fourth slider 222 is disposed on one side of the third slider 221 and connected to the transfer component 30 on the other side, for driving the transfer component 30 to move along the second direction.

[0050] Specifically, in this embodiment, it should be noted that the second propulsion component 22 includes a third slider 221 and a fourth slider 222. The third slider 221 is disposed on the second slider 212 and is used to provide linear guidance in the first direction. One side of the fourth slider 222 is disposed on the third slider 221, and the other side is connected to the transfer component 30. During operation, the second slider 212 drives the third slider 221 to slide linearly along the first direction. The third slider 221 serves as a bearing platform to maintain guidance and position reference in the first direction. Based on this, the fourth slider 222 slides relative to the third slider 221 along the second direction, and through its connection with the transfer component 30, enables the transfer component 30 to be positioned and moved in the second direction. The third and fourth sliders 222 are coupled by linear sliding to ensure smooth guidance and stable repeatable positioning under load and acceleration / deceleration conditions.

[0051] Furthermore, the movement in the second direction is achieved by the fourth slider 222 relative to the third slider 221. Due to the simple structure and clear motion relationship, the gap superposition and deformation accumulation are reduced, which not only helps to improve the positioning consistency and repeatability, but also reduces the error caused by gap superposition.

[0052] In one specific embodiment, the fourth sliding member 222 includes a slide rail 2221, a fixing plate 2222, and a limiting member 2223. One end of the fixing plate 2222 is slidably connected to the slide rail 2221, and the other end is fixedly connected to the transfer assembly 30. The fixing plate 2222 has a limiting groove 2222a along the second direction. The limiting member 2223 is disposed on the slide rail 2221 and extends into the limiting groove 2222a.

[0053] Specifically, in this embodiment, it should be noted that the fourth sliding member 222 includes a slide rail 2221, a fixed plate 2222, and a limiting member 2223. One end of the fixed plate 2222 is slidably connected to the slide rail 2221, and the other end is fixedly connected to the transfer assembly 30. The fixed plate 2222 has a limiting groove 2222a along the second direction, and the limiting member 2223 is disposed on the slide rail 2221 and extends into the limiting groove 2222a. During operation, the fixed plate 2222 slides linearly along the second direction under the guidance of the slide rail 2221, and the limiting member 2223 moves relative to the fixed plate 2222 and is guided within the limiting groove 2222a, limiting the travel range of the fixed plate 2222 and constraining its direction of movement. The transfer assembly 30 achieves positioning and movement in the second direction with the fixed plate 2222. Furthermore, the sliding engagement between the slide rail 2221 and the fixed plate 2222 provides stable linear guidance for the second direction, ensuring that the transfer assembly 30 moves in the predetermined direction; at the same time, the engagement between the limiting member 2223 and the limiting groove 2222a serves as a mechanical limit and stroke constraint to prevent overtravel and improve the consistency and repeatability of positioning.

[0054] Furthermore, the engagement of the limiting member 2223 within the limiting groove 2222a also provides lateral constraint, suppressing the offset and swaying of the fixed plate 2222 in directions other than the second direction, thus maintaining the stability of the end-effector posture. Since the fixed plate 2222 is directly connected to the transfer assembly 30, the transmission link is shorter, thereby reducing the impact of the superposition of mating clearances on positioning accuracy.

[0055] Therefore, the backlight transfer mechanism 1000 provided above uses multiple transfer components 32 arranged in a ring along the support component 31, which can flexibly combine to work according to the size and shape of the backlight, realizing multi-point adsorption or local adsorption. The identification component 40 is not only used to detect the position of the backlight, but also to identify the shape and placement posture of the backlight, thereby determining the specifications and type of the backlight; the system automatically activates the corresponding transfer component 32 to perform the adsorption operation based on the identification result, realizing intelligent grasping according to shape matching. The dual propulsion component provides a smooth composite displacement path, and the identification component 40 and the ring-distributed transfer components 32 work together to make the transfer process smooth and highly repeatable. The overall structure reduces the problem of uneven force on the backlight during the transfer process, realizing low-damage grasping and efficient transfer of the backlight.

[0056] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
