Description

Technical Field

[0001] This utility model belongs to the field of keyboard assembly tooling technology, specifically relating to a scissor-leg gripper mechanism and a scissor-leg assembly tooling. Background Technology

[0002] Scissor-switch switches are a crucial component of keyboards. Located beneath the keycaps, they connect the keycaps to the keyboard support plate, allowing the keycaps to rise or fall, thus engaging or disengaging with the spring switches on the flexible circuit board. The thin and compact nature of scissor-switch switches makes them difficult to handle and assemble. Appropriate force is required during handling and assembly; otherwise, they are easily damaged. Current assembly methods primarily rely on manual labor, which is inefficient. Alternatively, grippers are used, but the clamping force is difficult to control, making the scissor-switch switches prone to damage.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a scissor-leg gripper mechanism that can stably grip the scissor legs and prevent damage to the scissor legs during the gripping process.

[0005] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:

[0006] A scissor-leg gripper mechanism includes:

[0007] The first clamping member has a clamping surface;

[0008] The second clamping member is slidably connected to the first clamping member. The second clamping member has a first abutting surface and a second abutting surface connected to each other, and there is an included angle greater than 0 degrees between the first abutting surface and the second abutting surface.

[0009] The first abutting surface, the second abutting surface, and the clamping surface form a clamping space.

[0010] In one or more embodiments of the present invention, a first cylinder is mounted on the first clamping member, and the piston rod of the first cylinder is connected to the second clamping member.

[0011] In one or more embodiments of the present invention, the second clamping member has a second slot, and the piston rod of the first cylinder engages with the second slot.

[0012] In one or more embodiments of the present invention, the second clamping member includes a detachably connected main frame portion and a sliding cover portion, the main frame portion and the sliding cover portion forming a sliding space, and the first clamping member passing through the sliding space.

[0013] In one or more embodiments of this utility model, a pressure member is provided at one end of the second clamping member facing the clamping surface.

[0014] In one or more embodiments of this utility model, the pressing element is a rubber pad.

[0015] In one or more embodiments of the present invention, the scissor-leg gripper mechanism further includes a fixed base, and the first clamping member is slidably mounted on the fixed base.

[0016] In one or more embodiments of this utility model, a second cylinder is mounted on the fixed base, and the piston rod of the second cylinder is connected to the first clamping member.

[0017] In one or more embodiments of this utility model, a sliding groove is provided on the fixed base, and a slider that is slidably connected to the sliding groove is provided on the first clamping member.

[0018] A specific embodiment of this utility model also provides a scissor-leg assembly fixture, including the aforementioned scissor-leg gripper mechanism.

[0019] Compared with the prior art, the scissor-leg gripper mechanism of this utility model forms a clamping space between the first abutment surface, the second abutment surface, and the clamping surface. During the clamping process, the scissor leg is located within the clamping space, that is, the scissor leg simultaneously abuts against the first abutment surface, the second abutment surface, and the clamping surface. In other words, the scissor-leg gripper mechanism of this utility model uses three surfaces to clamp and restrict the scissor leg. Therefore, it is not necessary to clamp too tightly during the clamping process to stably clamp the scissor leg. This avoids the problem of excessive clamping force causing damage to the scissor leg, and insufficient clamping force causing the scissor leg to be unstablely clamped by the gripper mechanism, resulting in the scissor leg falling off or its placement position shifting, making it impossible to align it with the designated position on the keyboard.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0026] like Figure 1 and 2 As shown, the scissor-leg gripper mechanism in one embodiment of the present invention includes a first gripper 1 and a second gripper 2; the first gripper 1 has a gripping surface 11; the second gripper 2 is slidably connected to the first gripper 1, and the second gripper 2 has a first abutting surface 23 and a second abutting surface 24 connected to each other, and there is an included angle greater than 0 degrees between the first abutting surface 23 and the second abutting surface 24; wherein, a gripping space 4 is formed between the first abutting surface 23, the second abutting surface 24 and the gripping surface 11.

[0027] It is understood that the scissor legs are located within the clamping space 4 during the clamping process, meaning that the scissor legs simultaneously abut against the first contact surface 23, the second contact surface 24, and the clamping surface 11. In other words, the scissor leg gripper mechanism of this utility model uses three surfaces to clamp and restrict the scissor legs. This means that the scissor legs do not need to be clamped too tightly during the clamping process, and can be stably clamped. This avoids the problem of excessive clamping force causing damage to the scissor legs in the prior art, and insufficient clamping force causing the scissor legs to be unstablely clamped by the gripper mechanism, resulting in the scissor legs falling off or their placement position shifting, making it impossible to align them with the designated position on the keyboard.

[0028] It should be noted that, since there is an angle greater than 0 degrees between the first abutment surface 23 and the second abutment surface 24, the scissor legs also form a certain angle with the horizontal plane during the clamping process. That is, during the installation of the scissor legs onto the keyboard, one end of the scissor legs first contacts and engages with the clip or groove on the keyboard. Then the scissor leg clamping mechanism will move. Since one end of the scissor legs has already been engaged with the keyboard and the first abutment surface 23, the second abutment surface 24 and the clamping surface 11 are in cooperation, the scissor legs are not clamped by a large force. Therefore, the scissor legs will not move (that is, the scissor legs will gradually fall off from the clamping space 4). The first abutment surface 23 or the second abutment surface 24 on the scissor leg clamping mechanism or other parts on the second clamping member 2 will abut against the scissor legs and press the part of the scissor legs that is not in contact with the keyboard onto the keyboard, thereby realizing the assembly of the scissor legs and the keyboard.

[0029] In one specific embodiment, a first cylinder 12 is mounted on the first clamping member 1, and the piston rod of the first cylinder 12 is connected to the second clamping member 2. The first cylinder 12 is used to control the sliding position of the second clamping member 2 on the first clamping member 1. In addition, cylinder control helps to improve the degree of automation and accurately control the sliding position of the second clamping member 2.

[0030] Specifically, the second clamping member 2 has a second slot 25, and the piston rod of the first cylinder 12 is engaged with the second slot 25, thereby connecting the second clamping member 2 and the piston rod of the first cylinder 12.

[0031] Specifically, the second clamping member 2 includes a detachably connected main frame portion 21 and a sliding cover portion 22, which together form a sliding space 26. The first clamping member 1 passes through the sliding space 26. That is, the second clamping member 2 is sleeved on the outside of the first clamping member 1. This arrangement can limit the sliding direction of the second clamping member 2 and also connect the second clamping member 2 and the first clamping member 1.

[0032] Specifically, the second clamping member 2 has a pressure member 27 at one end facing the clamping surface 11. That is, during the assembly of the scissor legs, the pressure member 27 serves to press the scissor legs firmly onto the keyboard.

[0033] Preferably, the pressing component 27 is a rubber pad. The rubber pad has good elasticity and softness, preventing damage to the scissor legs during the pressing process.

[0034] like Figure 1 and 2As shown in one specific embodiment, the scissor-leg gripper mechanism further includes a fixed base 3, and a first gripper 1 is slidably mounted on the fixed base 3. When the scissor-leg gripper mechanism picks up the scissor legs from the tray or installs the scissor legs onto the keyboard, the first gripper 1 can slide against the fixed base 3 to approach the scissor legs and / or the keyboard. Then, the first gripper 1 cooperates with the second gripper 2 to realize the process of picking up the scissor legs or installing the scissor legs onto the keyboard.

[0035] Specifically, a second cylinder 32 is installed on the fixed base 3, and the piston rod of the second cylinder 32 is connected to the first clamping member 1. The second cylinder 32 is used to control the sliding position of the first clamping member 1 on the fixed base 3. In addition, cylinder control helps to improve the degree of automation and accurately control the sliding position of the first clamping member 1.

[0036] Furthermore, the first clamping member 1 has a first slot 13, and the piston rod of the second cylinder 32 engages with the first slot 13, thereby connecting the first clamping member 1 and the piston rod of the second cylinder 32.

[0037] Specifically, the fixed base 3 is provided with a sliding groove 31, and the first clamping member 1 is provided with a slider 14 that is slidably connected to the sliding groove 31. This arrangement can limit the sliding direction of the first clamping member 1 and support the sliding of the first clamping member 1. A specific embodiment of this utility model also provides a scissor-leg assembly fixture, including the above-mentioned scissor-leg gripper mechanism.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
