Technical Field

[0001] The utility model relates to the technical field of FCBGA packaging substrate production, in particular to a locking device, a cover plate and a hanging basket. Background Art

[0002] With the rapid development of semiconductors, the production of IC substrates has more stringent requirements on production line particles. In the substrate production process, copper needs to be plated on the substrate. In the copper deposition process, the substrate needs to be immersed in a copper deposition pool. The tool for immersing the substrate in the copper deposition pool is called a hanging basket. The hanging basket is used to fix the substrate. When the substrate is fixed in the hanging basket, a cover plate needs to be set on the hanging basket frame to fix the substrate. The existing upper cover and the method of fixing the cover plate are manually operated. Manual operation will cause the stains on the hands to contact the board, causing pollution to the board and reducing the quality of the board. In addition, the manual operation method of fixing the cover plate is inefficient. Utility Model Content

[0003] In order to overcome the defects in the prior art, the embodiments of the utility model provide a locking device, a cover plate and a hanging basket, which can automatically fix the cover plate on the locking device, and the cover plate is firmly fixed, which can realize full automatic non-human contact with the panel, reduce direct contamination of the panel, improve the quality of the panel, and improve production efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The first aspect of the utility model discloses a locking device, comprising:

[0006] A fixing member, wherein a first end of the fixing member is provided with a fixing groove extending from the first end of the fixing member to the second end of the fixing member;

[0007] A support member, the support member is disposed around the fixing member and is fixedly connected to the fixing member, and the upper end of the support member is at the same height as the bottom of the fixing groove;

[0008] A locking member, wherein the locking member is arranged at the first end of the fixing member and is rotatably connected to the fixing member. The locking member cooperates with the supporting member to lock other components by rotating. When the locking member and the supporting member are in a locked state, the locking member locks the component to be locked between the locking member and the supporting member.

[0009] The above technical solution fixes the component to be fixed on the fixing member by setting a fixing groove at the first end of the fixing member, and sets a rotatable locking member and a supporting member to cooperate in locking the component to be fixed. The component to be fixed can be automatically fixed on the locking device, and no personnel can contact the panel, thereby improving efficiency.

[0010] Preferably, the locking member includes a locking portion and a connecting portion, and a pin hole is provided on the first end of the fixing member and the locking portion, a pin is passed through the pin hole, and the pin passes through the pin hole to rotatably connect the locking member to the fixing member.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In addition, the drawings of the utility model are only simple schematic illustrations and are not depicted according to actual sizes. Please note in advance.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0041] It should be understood that, although the terms "first", "second", "third", etc. may be used herein to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used herein may include any one or more combinations of the associated listed items depending on the actual situation.

[0042] Reference Figure 1-2 , the present application shows a front view and a rear view structure of a locking device. Figure 1 As shown, the locking device 7 includes a fixing member 1, a supporting member 2, a locking portion 4 and a connecting portion 5. The first end of the fixing member 1 is provided with a fixing groove extending along the first end of the fixing member 1 toward the second end of the fixing member 1. The fixing groove is preset with a groove depth, and the depth of the fixing groove can be set according to actual conditions. In a possible embodiment, the fixing groove is set to an irregular groove shape, so that the first end of the fixing member 1 forms two fixing units 3 connected to the fixing member 1 body, and the fixing unit 3 is set to a symmetrical trapezoidal structure.

[0043] It should be noted that the first end and the second end in the above embodiment are only for the convenience of explaining the positions of the structural components of the fixing member 1, and do not limit the setting positions of the specific structures.

[0044] The cross-sectional diameter of the notch of the fixing groove near the first end of the fixing member 1 is larger than the cross-sectional diameter of the notch away from the first end of the fixing member 1. When the component to be fixed slides down from the top of the fixing groove to the bottom 6 of the fixing groove, the larger cross-sectional diameter of the notch near the first end of the fixing member 1 can facilitate the falling of the component to be fixed, while the smaller cross-sectional diameter of the notch near the bottom 6 of the fixing groove can enable the component to be fixed to fall accurately to the fixed position and fix the component to be fixed.

[0045] Reference Figure 3, the present application shows a top view of a locking device. Figure 3 In the embodiment, the cross section of the bottom 6 of the fixing groove is set to be square. In other feasible embodiments, the cross section of the bottom 6 of the fixing groove can also be set to other shapes, which will not be described in detail in this application.

[0046] The bottom 6 of the fixing groove is used to cooperate with the fixing groove to fix the component to be fixed. In the embodiment of the present application, the component to be fixed is a cover plate 8. The cover plate 8 is arranged above the substrate when the substrate is subjected to chemical copper deposition to fix the substrate. Figure 4 , this application shows a structural diagram of a cover plate 8. Figure 4 As shown, the cover plate 8 is configured as a long strip structure, and fixing portions 20 are provided at both ends of the short sides of the cover plate 8. The fixing portions 20 are used to clamp the cover plate 8 on the bottom 6 of the fixing groove, thereby fixing the cover plate 8 on the locking device 7. A plurality of tooth grooves 21 are connected to the cover plate 8, and the tooth grooves 21 are used to clamp the substrate.

[0047] The second end of the fixing member 1 is used to fix the fixing member 1 to other components. In a possible embodiment, a bolt hole is opened at the second end of the fixing member 1, and the fixing member 1 is fixed to the hanging basket by bolts.

[0048] The fixing member 1 is fixedly connected with a support member 2, which is arranged around the fixing member 1 and forms a through hole with the fixing member 1. The cross-sectional profile of the structure formed by the through hole and the bottom 6 of the fixing groove is T-shaped, which can support the cover plate 8 when fixing the cover plate 8, so that the cover plate 8 is more firmly fixed on the locking device 7. The end surface of the upper end of the support member 2 is at the same height as the bottom 6 of the fixing groove, and the upper end of the support member 2 is the end close to the first end of the fixing member 1. When locking the cover plate 8, the support member 2 can play a reinforcing role, so that the cover plate 8 remains stable when fixed on the locking device 7.

[0049] The first end of the fixing member 1 is connected with a locking member, which is rotatably connected to the fixing member 1, and the locking member includes a locking portion 4 and a connecting portion 5. In a possible embodiment, the locking portion 4 and the connecting portion 5 are arranged on the outside of the first end of the fixing member 1. When the connecting portion 5 is arranged on the outside of the first end of the fixing member 1, the locking member can be rotated in only one direction, so as to ensure that the cover plate 8 is prevented from being separated from the device to be locked 7 when the cover plate 8 is subjected to the buoyancy of liquids such as water. Pin shaft holes are provided on the fixing unit 3 and the locking portion 4, and a pin shaft is passed through the pin shaft hole. The pin shaft passes through the pin shaft hole to rotatably connect the locking portion 4 with the fixing unit 3.

[0050] The locking part 4 has a connecting end and an extending end, one side of the connecting end is used to connect with the connecting part 5, and the other side extends along the upper end surface of the connecting end in a first direction to form an extending end, and the angle formed by the first extending direction and the upper end surface of the connecting end is in the range of 15° to 60°. The upper end surface of the extending end has an inclination, which enables the cover plate 8 to be placed above the locking device. Due to the inclination of the extending end and the gravity of the cover plate 8, the locking piece is easier to rotate, so that the cover plate 8 can slide down to the bottom 6 of the fixing groove more easily. The applicant found that when the angle formed by the extending direction of the extending end and the upper end surface of the connecting end is in the range of 15° to 60°, the automatic rotation effect of the locking piece is better. In a possible embodiment, the locking part 4 can be set as an inverted L-shaped structure as a whole, and the corresponding positions on the extending end and the fixing unit 3 are both provided with a pin shaft hole, and a pin shaft is passed through the pin shaft hole to rotatably connect the extending end with the fixing unit 3.

[0051] The locking member locks the cover plate 8 on the locking device 7 by rotating and cooperating with the support member 2. When the locking member and the support member 2 are in a locked state, at least a portion of the cover plate 8 is locked between the locking member and the support member 2. When the cover plate 8 is locked, there is a gap between the bottom of the extension end and the cover plate 8, and the gap is used for the robot to rotate the locking member to release the locking state of the locking member.

[0052] Reference Figure 5 , as shown in the figure, when the locking device 7 locks the cover plate 8, the working principle of the locking device 7 automatically locking the cover plate 8 is: the manipulator places the cover plate 8 above the fixing groove, and due to the influence of the cover plate 8's own gravity, the cover plate 8 falls to contact with the locking part 4, and since the locking part 4 is rotatably connected to the fixing unit 3, the cover plate 8 is pressed on the locking part 4 to rotate the locking part 4, and the cover plate 8 slides down, and the fixing part 20 is stuck at the bottom 6 of the fixing groove. Part of the cover plate 8 is supported on the support member 2, and the locking member automatically rotates to the original position to lock the cover plate 8. When the cover plate 8 needs to be removed, the manipulator rotates the locking member to take out the cover plate 8.

[0053] By means of the above structure, a fixing groove is set at the first end of the fixing part, and a supporting part is set to cooperate with the rotatable locking part to lock, so that the cover plate can be automatically locked, and the cover plate is firmly fixed, which can prevent the stains on the hands of personnel from contacting the cover plate during operation, and when the cover plate is immersed in water or other liquids, the stains are transferred to the water or other liquids, causing contamination of the plate, which can improve the quality of the plate, and the cover plate can be taken and placed by a robot, which can reduce manpower and reduce costs.

[0054] Reference Figure 6-7The present application shows a schematic diagram of a hanging basket structure. The hanging basket as a whole forms a frame-like structure, including a bottom frame and a side frame. The bottom frame includes a first support rod 9 arranged along the length direction and a first cross bar 10 arranged along the width direction.

[0055] The side frame is arranged around the bottom frame, and the side frame includes a support frame 11 arranged in the vertical direction. The hanging basket is provided with four support frames 11, which are arranged at the four corners of the bottom frame. One end of the support frame 11 is connected to the first support rod 9 and the first cross bar 10, and the other end is connected to the second support rod 12. The second support rod 12 is arranged along the width direction, and a hook 13 is provided on the second support rod 12.

[0056] The side frame is connected with a plurality of first cross bars 10 , which are arranged on the side frame in sequence and spaced apart in the vertical direction and connected to the support frame 11 . The first cross bars 10 are provided with a plurality of connecting shafts 19 .

[0057] The support frame 11 is connected with a second cross bar 14 and a third support bar 15 along the length direction. The first support bar 9, the second cross bar 14 and the third support bar 15 are arranged on the hanging basket in sequence and spaced apart along the vertical direction. The support frame 11 and the second cross bar 14 and the third support bar 15 are surrounded to form the side frame.

[0058] The hanging basket is connected to a plurality of clips 16, which are respectively fixed on the bottom frame and the side frame. The clips 16 are provided with supporting parts 18, and the clips 16 are connected and fixed to the bottom frame with the first supporting rod 9 through the supporting parts 18. The connecting shaft 19 on the first cross bar 10 is connected to the supporting parts 18 to fix the clips 16 to the side frames.
