Description

Technical Field

[0001] The utility model relates to the technical field of COB substrate mounting, in particular to a COB substrate mounting pre-positioning platform. Background Art

[0002] COB mounting is to mount multiple chips on a joint substrate composed of multiple substrates. During mounting, the substrate needs to be positioned to ensure that the mounting mechanism can accurately mount multiple chips on the joint substrate. For the positioning of the substrate, workers usually manually or conveying equipment transfers the substrate to the positioning area of ​​the positioning mechanism to achieve pre-positioning of the substrate.

[0003] However, when the substrate is transferred manually or by conventional conveying equipment, the longitudinal position, lateral position and posture of the substrate are uncertain, which increases the difficulty of subsequent precise positioning. If the substrate is transferred using precision equipment such as a robot, it is not only inefficient but also has high hardware costs. Utility Model Content

[0007] A push cylinder is fixedly arranged at the axis of the receiving tray, and a correction push plate is arranged at one end of the push cylinder;

[0008] The pushing cylinder intermittently pushes the correction push plate, so that the substrate moved into the receiving groove between the correction push plate and the positioning table is pushed onto the positioning table.

[0009] Furthermore, it also includes a material receiving platform arranged on one side of the positioning platform, the material receiving tray is rotatably arranged on the material receiving platform, and one side of the positioning platform is in an arc shape that matches the gap of the edge of the material receiving tray, and the top of the positioning platform and the bottom of the material receiving trough are at the same horizontal height.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figures 1 to 3As shown, a COB substrate mounting pre-positioning platform includes a positioning platform 1 arranged below a mounting mechanism, and also includes a receiving tray 2 rotatably arranged on one side of the positioning platform 1, the receiving tray 2 is annular and rotates intermittently, and the receiving tray 2 is provided with a plurality of receiving grooves 3 arranged around its rotation axis, and the receiving grooves 3 penetrate the inner peripheral side wall and the outer peripheral side wall of the receiving tray 2;

[0023] A push cylinder 4 is fixedly arranged at the axis of the receiving plate 2, and a correction push plate 5 is arranged at one end of the pushing cylinder 4. The width of the receiving groove 3 is greater than the width of the substrate and the correction push plate 5.

[0024] The pushing cylinder 4 intermittently pushes the correction push plate 5 so that the substrate moved to the receiving groove 3 between the correction push plate 5 and the positioning table 1 is pushed onto the positioning table 1 .

[0025] Specifically, the substrate is manually loaded by a worker or transported to the receiving trough 3 by a conveying device. The width of the receiving trough 3 is greater than the width of the substrate to facilitate the placement of the substrate and to avoid the substrate from getting stuck when moving in the receiving trough 3 due to the error in the positioning accuracy of the receiving tray 2, that is, the receiving trough 3 is not parallel to the movement path of the correction push rod.

[0026] When the receiving trough 3 containing the substrate rotates with the receiving tray 2 and moves to the alignment position between the correction push plate 5 and the positioning table 1, the pushing cylinder 4 pushes the correction push plate 5 through the receiving trough 3, and pushes the substrate in the receiving trough 3 onto the positioning table 1. Since the pushing distance of the correction push plate 5 is fixed and the side of the correction push plate 5 close to the positioning table 1 is flat, the longitudinal position and posture of the substrate pushed onto the positioning table 1 are determined, thereby realizing the pre-positioning of the substrate.

[0027] Since the width of the receiving slot 3 is greater than the width of the substrate, the position of the substrate in the width direction of the receiving slot 3 is uncertain. After the substrate is transferred to the positioning platform 1, the substrate is repositioned in the length direction of the substrate to achieve accurate positioning of the substrate.

[0028] The utility model receives the substrate via a receiving tray 2 provided with a plurality of receiving grooves 3. After the receiving groove 3 with the substrate moves between the positioning platform 1 and the correction push plate 5, the pushing cylinder 4 drives the correction push plate 5 to pass through the receiving groove 3 with the substrate. During the process, the posture of the substrate is adjusted with the aid of the correction push plate 5, so that the longitudinal position and posture of the substrate on the positioning platform 1 are determined to realize the pre-positioning of the substrate. The structure is simple and reliable, which is conducive to reducing hardware costs and subsequent use costs.

[0029] The pre-positioning platform also includes a receiving platform 6 arranged on one side of the positioning platform 1, and the receiving tray 2 is rotatably set on the receiving platform 6, and one side of the positioning platform 1 is in an arc shape that matches the gap between the edge of the receiving tray 2, and the top of the positioning platform 1 and the bottom of the receiving trough 3 are at the same horizontal height, so as to facilitate the stable transfer of the substrate from the receiving tray 2 to the positioning platform 1 and to improve the aesthetics.

[0030] In addition, a circular boss 7 is provided on the material receiving platform 6, the material receiving tray 2 is rotatably sleeved on the boss 7, and the pushing cylinder 4 is arranged on the top of the boss 7. The function of the boss 7 is to position the material receiving tray 2 and provide a position for the installation of the pushing cylinder 4.

[0031] In addition, a downwardly inclined unloading slope 8 is provided on the side of the positioning table 1 away from the receiving table 6. When the substrate on the positioning table 1 is mounted and the next substrate is transferred to the positioning table 1, it will be pushed onto the unloading slope 8 by the next substrate and slide along the unloading slope 8 to the collection device or transfer device below.

[0032] In addition, a driving wheel 9 is rotatably provided on the receiving platform 6, a gear ring 10 meshing with the driving wheel 9 is sleeved on the receiving tray 2, and the driving wheel 9 is connected to a servo motor, thereby realizing intermittent rotation of the receiving tray 2.

[0033] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the embodiments disclosed above are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
