[0036] Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention and other matters necessary for those skilled in the art to readily understand the content of the present invention will be described in detail. In the following description, singular expressions include plural expressions as well as singular expressions unless explicitly stated in the context.

[0037] Figure 1 This is a front view of a mobile device according to an embodiment of the present invention.

[0038] Reference Figure 1 The moving device 10 may include a tray TRY, a ball spline BSP, a motor MT, a bracket BRK, a first pulley PUL1, a second pulley PUL2, a belt BLT, a first support shaft SPA1, a second support shaft SPA2, a first bushing BS1, and a second bushing BS2.

[0039] The moving device 10 can be used to supply or discharge a product PD loaded on a tray TRY to an inspection device. For example, the product PD may be a display panel. That is, after the product PD is loaded on the tray TRY, the moving device 10 can move the product PD in the z-axis or -z-axis direction. The moving device 10 can move the product PD in the z-axis direction to supply it to the inspection device, and can move the product PD in the -z-axis direction to discharge it from the inspection device. However, the moving device 10 according to the embodiments of the present invention is not limited to this, and can be used to supply or discharge a product PD to other equipment, and can move the product PD in directions other than the z-axis direction.

[0040] The tray TRY can be connected to the ball spline BSP. The ball spline BSP may include a moving part MP and a moving guide shaft MGA. For example, the moving part MP may be mounted on the moving guide shaft MGA, and the moving guide shaft MGA may be connected to the tray TRY.

[0041] Specifically, the ball spline BSP can receive power from the motor MT to move the tray TRY in the z-axis or -z-axis direction. That is, the moving part MP can rotate along the moving guide shaft MGA and move in a linear direction. Thus, the tray TRY can move in the z-axis or -z-axis direction.

[0042] Each of the first support shaft SPA1 and the second support shaft SPA2 can be connected to the tray TRY in the same manner as the movable guide shaft MGA. The first support shaft SPA1 and the second support shaft SPA2 can be connected to the first bushing BS1 and the second bushing BS2, respectively. That is, the first bushing BS1 and the second bushing BS2 can be mounted on the first support shaft SPA1 and the second support shaft SPA2, respectively.

[0043] The first bushing BS1 and the second bushing BS2 can move linearly along with the movement of the moving part MP. That is, the first bushing BS1 and the second bushing BS2 can move along the first support shaft SPA1 and the second support shaft SPA2 respectively, corresponding to the movement of the moving part MP in the z-axis or -z-axis direction. Due to the first bushing BS1 and the second bushing BS2, the tray TRY can move smoothly and easily in a linear direction.

[0044] Additionally, the first support shaft SPA1 and the second support shaft SPA2, together with the moving guide shaft MGA, can support the tray TRY. Thanks to the first support shaft SPA1 and the second support shaft SPA2, the tray TRY can remain horizontal and move without tilting to one side.

[0045] The electric motor MT can be fixed to the bracket BRK and connected to the first pulley PUL1. The electric motor MT generates power, which is then transmitted to the first pulley PUL1. The first pulley PUL1 can be connected to the electric motor MT and receive power from the electric motor MT, transmitting the power to the belt BLT that wraps around the first pulley PUL1. The belt BLT can wrap around the first pulley PUL1 and the second pulley PUL2, transmitting the power received from the first pulley PUL1 to the second pulley PUL2. The second pulley PUL2 can be connected to the ball spline BSP, transmitting the received power to the ball spline BSP. Therefore, the ball spline BSP can receive power from the electric motor MT through the first pulley PUL1, the belt BLT, and the second pulley PUL2, thus moving the tray TRY.

[0046] Figure 2 It is a brief illustration Figure 1 The front view of a portion of the mobile device.

[0047] exist Figure 2 For ease of explanation, only the first pulley PUL1, the second pulley PUL2, the belt BLT, the motor MT, and the bracket BRK are shown.

[0048] Reference Figure 2 The first pulley PUL1 and the second pulley PUL2 can be spaced apart from each other. The belt BLT can simultaneously wrap around both the first pulley PUL1 and the second pulley PUL2, connecting them. The belt BLT can simultaneously wrap around the outer circumference of each of the first pulley PUL1 and the second pulley PUL2. That is, through the belt BLT, the power of the first pulley PUL1 can be transmitted to the second pulley PUL2.

[0049] Each of the first pulley PUL1 and the second pulley PUL2 may include a wing WP protruding from its outer peripheral surface. The wing WP included in the first pulley PUL1 may be spaced apart from each other in the z-axis direction, and the wing WP included in the second pulley PUL2 may also be spaced apart from each other in the z-axis direction. A belt BLT may be disposed between the wing WPs included in the first pulley PUL1 in the portion enclosing the first pulley PUL1, and may be disposed between the wing WPs included in the second pulley PUL2 in the portion enclosing the second pulley PUL2. That is, since the wing WP protrudes from the outer peripheral surface of each of the first pulley PUL1 and the second pulley PUL2, the belt BLT disposed between the wing WPs may be located on the outer peripheral surface and not detached from it.

[0050] The first pulley PUL1 can be connected to the electric motor MT. The electric motor MT may also include a motor rod MTR protruding in the z-axis direction. The motor rod MTR can be attached to the first pulley PUL1, and the first pulley PUL1 and the electric motor MT are connected to each other.

[0051] The bracket BRK can be configured between the first pulley PUL1 and the motor MT. The bracket BRK can be connected to the motor MT and fix the motor MT in place. The motor rod MTR included in the motor MT can be connected to the bracket BRK.

[0052] The bracket BRK can be separated from the first pulley PUL1 by a predetermined interval. This prevents the bracket BRK and the first pulley PUL1 from colliding and being damaged.

[0053] Figure 3 It is a brief illustration Figure 2 The first pulley, bracket, and cross-sectional view of the motor.

[0054] Reference Figure 3The first pulley PUL1 may have a first hole HL1 and a second hole HL2. The first hole HL1 may be adjacent to the bracket BRK and located in the center of the first pulley PUL1. The second hole HL2 may be connected to the first hole HL1 and has a smaller diameter than the first hole HL1. That is, the first hole HL1 and the second hole HL2 form a large hole penetrating the center of the first pulley PUL1, but the diameter of the second hole HL2 is smaller than the diameter of the first hole HL1, so a step may be formed at the boundary between the first hole HL1 and the second hole HL2.

[0055] The motor rod MTR can be joined in the first hole HL1. One end of the motor rod MTR can contact the step between the first hole HL1 and the second hole HL2. That is, the motor rod MTR can be integrally joined to the first hole HL1, except for the second hole HL2, which is inaccessible due to the step. Therefore, the length L2 of the motor rod MTR located inside the first hole HL1 can be substantially the same as the length L1 of the first hole HL1.

[0056] By integrally engaging the motor rod MTR with the first hole HL1, pushing phenomena caused by incomplete engagement between the motor MT and the first pulley PUL1 can be prevented. Furthermore, the relative positions of the motor MT and the first pulley PUL1 remain unchanged, thus maintaining a constant position for each of the motor MT and the first pulley PUL1. In other words, the position of each of the motor MT and the first pulley PUL1 can be standardized. Moreover, by always integrally engaging the motor rod MTR with the first hole HL1 and standardizing the position of each of the motor MT and the first pulley PUL1, assembly deviations between the motor MT and the first pulley PUL1 can be avoided.

[0057] The first pulley PUL1 can be separated from the bracket BRK by a predetermined interval g. For example, the first pulley PUL1 and the bracket BRK can be separated by more than about 2 mm. If the predetermined interval g between the first pulley PUL1 and the bracket BRK is less than about 2 mm, the possibility of collision between the first pulley PUL1 and the bracket BRK may increase, thereby increasing the possibility of damage to both the first pulley PUL1 and the bracket BRK. That is, even if the motor rod MTR and the first hole HL1 are integrally connected, the first pulley PUL1 and the bracket BRK can avoid colliding with each other under any circumstances by being separated by the predetermined interval g.

[0058] The first pulley PUL1 may include a first part PT1 and a second part PT2. Specifically, the first part PT1 may be the portion adjacent to the bracket BRK, and the second part PT2 may be the portion adjacent to the first part PT1 in the z-axis direction but spaced apart from the bracket BRK.

[0059] The first part PT1 may include a fastening hole FHL on its outer peripheral surface. The fastening hole FHL may extend through the first part PT1. The motor rod MTR may also include a hole corresponding to the fastening hole FHL.

[0060] A headless bolt SSC can be inserted into the fastening hole FHL. The headless bolt SSC can be inserted through the first part PT1 and the motor rod MTR. That is, the first part PT1 and the motor rod MTR can be connected by the headless bolt SSC. The moving device 10 also includes a headless bolt SSC, which can increase the connection force between the motor MT and the first pulley PUL1 and fix the relative position of the first pulley PUL1 and the motor MT.

[0061] The second part PT2 may include wings WP protruding from the outer peripheral surface on the top and bottom surfaces respectively. The belt BLT wraps around the second part PT2 and is positioned between the wings WP, so that the wings WP can prevent the belt BLT from detaching from the second part PT2.

[0062] Figure 4 Is only shown Figure 3 Cross-sectional view of the first pulley.

[0063] Reference Figure 4 The width W1 of the first portion PT1 can be smaller than the width W2 of the second portion PT2. The first portion PT1 can serve as the insertion part of the headless bolt SSC. If the width W1 of the first portion PT1 becomes larger, the headless bolt SSC may not reach the motor rod MTR, or the headless bolt SSC may become excessively long. Therefore, the width W1 of the first portion PT1 can be made smaller than the width W2 of the second portion PT2. However, the embodiments according to this utility model are not limited to this.

[0064] In one embodiment, the diameter D1 of the first hole HL1 can be larger than the diameter D2 of the second hole HL2. The diameter D1 of the first hole HL1 can be approximately 2 mm or more larger than the diameter D2 of the second hole HL2. For example, the diameter D1 of the first hole HL1 can be approximately 18 mm or more, and the diameter D2 of the second hole HL2 can be approximately 16 mm or more. However, the embodiments according to this utility model are not limited thereto.

[0065] When the diameter D1 of the first hole HL1 is less than approximately 2mm larger than the diameter D2 of the second hole HL2, the step ST between the first hole HL1 and the second hole HL2 is small and engages with the first hole HL1. Figure 3The motor rod MTR may not engage with the step ST. That is, the motor rod MTR engaging with the first hole HL1, or the step ST between the first hole HL1 and the second hole HL2, may wear down due to repeated use of the moving device 10. Consequently, the motor rod MTR may not contact the step ST and may enter the second hole HL2. In this case, the relative position between the first pulley PUL1 and the motor MT changes, and the distance between the first pulley PUL1 and the motor MT may decrease. That is, a collision may occur between the first pulley PUL1 and the bracket BRK.

[0066] In one embodiment, the length L1 of the first hole HL1 can be greater than the length L3 of the second hole HL2. That is, the proportion occupied by the length L1 of the first hole HL1 can be more than 50% compared to the length L4 of a through hole that combines the first hole HL1 and the second hole HL2.

[0067] By ensuring that the length L1 of the first hole HL1 is greater than the length L3 of the second hole HL2, the motor rod MTR can be more stably connected to the first pulley PUL1. If the length L1 of the first hole HL1 is less than or equal to the length L3 of the second hole HL2, the length L1 of the first hole HL1, which is the part where the motor rod MTR can be connected, becomes relatively smaller, and therefore the connection force between the motor MT and the first pulley PUL1 may be further reduced. However, since the length L1 of the first hole HL1 is greater than the length L3 of the second hole HL2, the length L1 of the first hole HL1, which is the part where the motor rod MTR is connected, becomes relatively larger, and the connection force between the motor MT and the first pulley PUL1 can be further increased.

[0068] Figure 5 It is shown Figure 3 The first pulley, the electric motor, and the tooling fixture are cross-sectional views.

[0069] For example, Figure 5 This is a diagram showing how the device is moved out of the moving unit 10 in order to replace the first pulley PUL1.

[0070] Reference Figure 5 The diameter D2 of the second hole HL2 can be greater than or equal to the width W3 of the tooling fixture FXT that engages with the second hole HL2. Preferably, the diameter D2 of the second hole HL2 can be substantially the same as the width W3 of the tooling fixture FXT. In this case, the tooling fixture FXT can be a gear puller.

[0071] When the second hole HL2 is greater than or equal to the width W3 of the tooling fixture FXT, the tooling fixture FXT can be engaged with the second hole HL2. For example, when the tooling fixture FXT is a gear remover, the second hole HL2 can be used when the gear remover is removed from the first pulley PUL1. That is, when the first pulley PUL1 is replaced, the gear remover can be used, thus preventing damage to other structures of the moving device 10 (e.g., bracket BRK, motor MT, etc.) used by other tools (e.g., hammer).

[0072] The technical concept of this utility model has been specifically described based on the foregoing embodiments; however, these embodiments should be noted as illustrative and not limiting.
