Description

[Technical Field]

[0001] The present invention relates to a container door panel, and more particularly to a door panel structure for a substrate container. [Background technology]

[0002] Conventional containers for placing substrates mainly have an opening formed at one location on either the top or side, and the substrates are loaded into the container one by one and arranged at intervals, and then the opening is closed with a door panel to prevent the contents from spilling out during transportation or movement of the container. Summary of the Invention [Problem to be solved by the invention]

[0003] However, the door panel is designed with a pivoting mechanism such as a knob, which drives a tenon or other structure within the door panel to protrude from the side edge of the door panel and engage with the opening of the container to close it. These knobs are provided with a locking hole for rotating, and an operator can insert the knob into the locking hole and rotate it manually, using a tool, or using an automated device. However, current designs are prone to vibration due to external forces such as movement or shaking, which can cause the locking hole to rotate unevenly and move away from its intended position. When using an automated device, the device and the locking hole will no longer be aligned directly, which can prevent the door from closing or locking properly.

[0004] Therefore, the inventors of the present invention believed that the above drawbacks could be improved, and after extensive research, they came up with the present invention, which effectively improves the above issues through rational design.

[0005] The present invention was made in consideration of the above circumstances, and its main purpose is to provide a door panel structure for a substrate container that uses a friction method to prevent structures such as lock holes from being displaced by vibration, thereby enabling the lock holes to be maintained in a predetermined position and enabling automated equipment to operate as expected.

[0006] Another object of the present invention is to provide a door panel structure for a substrate container that eliminates the need for assembly using members such as screws and achieves the goal of high-speed assembly.

[0007] Yet another object of the present invention is to provide a door panel structure for a substrate container that can more stably maintain the door panel in a locked state and prevent the door from being accidentally unlocked due to external forces such as vibration.

[0008] Yet another object of the present invention is to provide a door panel structure for a substrate container that more tightly engages the door panel with the substrate container and prevents problems such as the door panel shaking due to gaps existing between the substrate containers. [Means for solving the problem]

[0009] To achieve the above object, one aspect of the present invention provides a door panel structure for a substrate container, comprising a first plate body, a second plate body, a drive turntable, and at least one engagement plate member. The second plate body has a second plate portion and a frame portion surrounding the second plate portion, and the first plate body is fitted to the frame portion, with at least one through-hole formed in the frame portion. The drive turntable is pivotally mounted between the first plate body and the second plate body, and the drive turntable has a disk and at least one drive portion mounted on the disk. The engagement plate member is installed between the first plate body and the second plate body, and has an actuator, an actuator portion mounted on the actuator, and at least one engagement portion facing from the actuator body toward the through-hole in the frame portion. When the actuator portion is pushed by the drive portion and the drive turntable rotates, the actuator portion is pushed by the drive portion, thereby pushing the actuator, and the engagement portion passes through the through-hole and protrudes out of the frame portion of the second plate body. At least one resistance member is disposed between the first plate body and the second plate body, and the resistance member is located at an outer peripheral location relative to the driving turntable and abuts against the disc of the driving turntable in a frictional manner.

[0010] To achieve the above-mentioned other object, in one aspect of the present invention, the door panel structure for a substrate container preferably has the first plate body having a first plate portion and a plurality of first outer engagement portions provided on the first plate portion, the first plate portion having an outer edge, the first outer engagement portions being distributed so as to be disposed along the outer edge of the first plate portion, and the frame portion of the second plate body is provided with a plurality of second outer engagement portions for engaging the first outer engagement portions.

[0011] In order to achieve the above-mentioned further object, a door panel structure for a substrate container which is one aspect of the present invention preferably further includes at least one elastic force limiting element for abutting against the engagement plate member so as to prevent the engagement portion of the engagement plate member from retracting into the through hole.

[0012] To achieve the above-mentioned further object, a door panel structure for a substrate container according to one embodiment of the present invention preferably has at least one protrusion on the surface of the disk of the drive turntable, the protrusion having a guide surface that gradually becomes thicker from the surface, and an abutment portion that abuts against the surface on the operating portion of the engagement plate member. As the disk rotates, the guide surface of the protrusion rotates toward the abutment portion, and the engagement portion of the engagement plate member can slide toward one of the plate bodies (e.g., the first plate body or the second plate body), thereby more tightly engaging with the substrate container and preventing problems such as the door panel shaking due to a gap when the engagement portion 42 is inserted into the substrate container.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The following describes in detail the embodiments of the present invention, but the present invention is not limited to these, and various modifications are possible within the scope of the description. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention.

[0016] FIG. 1 is an exploded view showing a door panel structure for a substrate container according to one embodiment of the present invention.

[0017] The door panel structure for a substrate container of the present invention is installed on a substrate container (not shown) to close the substrate container and prevent the substrates inside from falling, and comprises a first plate body 1, a second plate body 2, a driving turntable 3, and at least one engaging plate member 4.

[0018] 1 and 2, the first plate body 1 has a flat plate shape and includes a first plate portion 10 and a plurality of first outer engagement portions 11 provided on the first plate portion 10. The first plate portion 10 has an outer edge 100, and the first outer engagement portions 11 are distributed so as to be arranged along the outer edge 100 of the first plate portion 10, and the first plate portion 10 is provided with a plurality of first inner engagement portions 12 located within each of the first outer engagement portions 11.

[0019] In this case, as shown in FIGS. 1 and 3, the second plate body 2 includes a second plate portion 20 and a frame portion 21 surrounding the second plate portion 20. The second plate body 2 fits the first plate body 1 onto the frame portion 21. The frame portion 21 further includes a plurality of second outer engaging portions 210 for engaging with the first outer engaging portions 11 of the first plate body 1. In this embodiment, each of the second outer engaging portions 210 is an engaging hole, and each of the first outer engaging portions 11 has a tenon 110 for engaging with the engaging hole. The second plate portion 20 also includes a plurality of second inner engaging portions 22 corresponding to the first inner engaging portions 12. The first plate body 1 and the second plate body 2 are connected to each other using the above-described engaging method, thereby achieving the goal of high-speed assembly. This reduces the assembly time required for assembly using screws or other fasteners.

[0020] 1 and 2, the driving turntable 3 is installed between the first plate body 1 and the second plate body 2. Specifically, it is located at the center of the first plate body 1 and the second plate body 2, but the present invention is not limited thereto. The driving turntable 3 has a disk 30 and at least one driving part 31 provided on the disk 30. The disk 30 is used to pivot to the second plate body 2, and the second plate body 2 is provided with a plate body pivot part 23. The disk 30 is provided with a turntable pivot part 300. The plate body pivot part 23 and the turntable pivot part 300 are pivotally connected to each other. In this embodiment, the plate body pivot part 23 is a pivot rod, and the turntable pivot part 300 is a pivot hole into which the pivot rod is inserted for pivoting. Furthermore, the disk 30 has at least one drive hole 301 formed on one side facing the first plate body 1, and the first plate body 1 has at least one arc-shaped track 101 corresponding to the drive hole 301. An operator can slide the drive hole 301 along the arc-shaped track 101 manually or by operating a tool, or by using an automated device, etc., thereby driving the drive turntable 3 to rotate.

[0021] As described above, the engagement plate member 4 is installed between the first plate body 1 and the second plate body 2 and is drivingly connected to the drive turntable 3. In this embodiment, there are two engagement plate members 4, each corresponding to the upper and lower sides of the frame portion 21 of the second plate body 2. Each engagement plate member 4 has an actuating body 40, an actuating portion 41 provided on the actuating body 40, and at least one engagement portion 42 directed from the actuating body 40 toward the frame portion 21. A recessed inner actuating edge 410 is formed in the actuating portion 41, and the shape of the inner actuating edge 410 matches the shape of the drive portion 31 of the drive turntable 3. When the drive turntable 3 rotates, the drive portion 31 presses against the actuating portion 41 along the inner actuating edge 410, thereby driving the engagement plate member 4 to reciprocate toward the frame portion 21 of the second plate body 2 via the engagement portion 42. The frame portion 21 has through holes 211 corresponding to each of the engagement portions 42, so that when the drive portion 31 of the drive turntable 3 presses against the actuating portion 41 along the actuating inner edge 410 and the engagement portion 42 of the engagement plate member 4 is pressed toward the frame portion 21 of the second plate main body 2, the engagement portion 42 passes through the through hole 211 and protrudes outside the frame portion 21 of the second plate main body 2, and the protruding engagement portion 42 enables the door panel to engage with the substrate container (not shown).

[0022] 2 and 4, the first plate body 1 and the second plate body 2 are provided with at least one resistance member 13 therein. The resistance member 13 is made of a material such as rubber and is fixed to the inner surface of either the first plate body 1 or the second plate body 2, and is located at an outer peripheral portion of the driving turntable 3. The resistance member 13 frictionally contacts the disc 30. In this embodiment, there are two resistance members 13, and each resistance member 13 may have a joint 130 fixed to the inner surface of either the first plate body 1 or the second plate body 2, and an abutment 131 protruding from the joint 130 toward the disc 30. This reduces the occurrence of situations where the contact portion 131 and the disk 30 come into frictional contact and the drive turntable 3 is prone to rotating unevenly due to external forces such as movement or shaking when pivoted to the first plate body 1 or the second plate body 2, and prevents problems such as the drive hole 301 being displaced from its designated position, making it impossible for the automated device to align its position or becoming inoperable.

[0023] 1 and 3, the present invention further includes at least one elastic force limiting element 5 that abuts against the engaging plate member 4 to maintain the engaging portion 42 protruding out of the frame portion 21 of the second plate body 2 through the through-hole 211, preventing the engaging portion 42 from retracting into the frame portion 21 due to an external force such as vibration of the engaging plate member 4, thereby preventing accidental unlocking. The elastic force limiting element 5 includes a flexible elastic force lever 50 and a support end 51 provided at the end of the flexible elastic force lever 50, which is used to fix the flexible elastic force lever 50 at an appropriate position between the first plate body 1 and the second plate body 2. In this embodiment, an embedding space 24 is provided on one side of the frame portion 21 of the second plate body 2, and the support end 51 is fixed in the embedding space 24, with the flexible elastic force lever 50 extending toward the engaging plate member 4. The front end of the flexible elastic lever 50 has a toggle end 500 that abuts against the operating body 40 of the engagement plate member 4, and the flexible elastic lever 50 pushes the operating body 40 toward one side of the engagement portion 42 (see Figure 5).

[0024] As described above, in detail, a plurality of ribs 400 for abutting the toggle end 500 are provided at the center of the actuating body 40 of the engagement plate member 4, and the ribs 400 are arranged at intervals so as to extend toward the toggle end 500. These ribs 400 not only provide structural strength to the engagement plate member 4, but also enable the flexible elastic force lever 50 and the actuating body 40 to maintain their operating positions at the center of the actuating body 40. In this way, when the engagement plate member 4 is displaced to reciprocate, the generation of angular momentum is prevented, and furthermore, operation is made smooth and stable.

[0025] Therefore, the door panel structure for a substrate container according to the present invention is obtained through the above structure.

[0026] As a result, as shown in Figure 4, when the door panel is unlocked, the drive portion 31 of the drive turntable 3 fits within the inner operating edge 410 of the operating portion 41 of the engagement plate member 4, and the disc 30 of the drive turntable 3 is rubbed against the abutment portion 131 of the resistance member 13, making it less susceptible to external forces such as vibrations and less likely to rotate unbalanced. This ensures that the automated device is accurately facing the drive hole 301 so as to be locked. At this time, the elastic force limiting element 5 is pushed by the operating body 40 of the engagement plate member 4 and bends (see Figure 5).

[0027] 6, to lock the door panel, an operator rotates the drive turntable 3 by manually operating a tool or by using an automated device, etc., which pushes the drive portion 31 of the drive turntable 3 against the actuating portion 41 along the inner actuating edge 410 of the actuating body 40 of the engagement plate member 4, driving the engagement plate member 4 so that the engagement portion 42 displaces toward the through-hole 211 of the frame portion 21 of the second plate body 2 and causes the engagement portion 42 to protrude out of the through-hole 211, thereby achieving the purpose of engaging the door panel with the substrate container (not shown). At this time, the disk 30 of the drive turntable 3 is subject to friction with the abutment portion 131 of the resistance member 13, making the disk 30 less susceptible to external forces such as vibration and less likely to rotate unbalanced, thereby ensuring that the automated device is accurately facing the drive hole 301 to release the lock. In this case, as shown in Figure 7, in the unlocked state, the elastic force limiting element 5 is subjected to a bending elastic force, which pushes the engaging portion 42 of the engaging plate member 4 into the through hole 211 and maintains the locked state (see Figure 8).

[0028] 1 and 2, the present invention further provides at least one protrusion 32 on the surface of the disk 30 of the drive turntable 3, the protrusion 32 having a guide surface 320 that gradually thickens from the surface, and the actuating portion 41 of the engaging plate member 4 having a butting portion 411 that abuts against the surface. When unlocked, the butting portion 411 abuts against the surface of the disk 30 (see FIG. 9). When locked, as the disk 30 rotates, the guide surface 320 of the protrusion 32 rotates toward the butting portion 411 (see FIG. 10). The butting portion 411 moves along the guide surface 320, deflecting the actuating portion 41 toward two positions on the second plate body 1. This allows the engaging portion 42 of the engaging plate member 4 to swing toward the first plate body 1 and engage more tightly with the substrate container. This prevents problems such as the door panel shaking due to a gap when the engaging portion 42 is inserted into the substrate container.

[0029] The present invention can be embodied in various other forms without departing from its spirit or essential characteristics. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as limiting. The scope of the present invention is defined by the scope of the utility model registration claims and is not bound by the specification. Furthermore, all modifications and alterations within the scope of the utility model registration claims are within the scope of the present invention. [Explanation of symbols]
