Keyboard spring turnover mechanism

Abstract

The utility model provides a keyboard spring turnover mechanism. In order to save the occupied space when the product is placed and avoid the situation that the springs are not knotted mutually, the springs can be stored in a material preparation area at a specific placing angle, and the springs stored at certain angles need to be installed on the product at another angle. The springs in the material preparing area can be carried and placed in the containing groove through the carrying module, then the air cylinder drives the pushing head to push one side of the overturning block to be overturned upwards so as to drive the springs in the containing groove to be overturned to the angle where the springs can be installed in the installation area, and therefore the angles of the springs can be reset or adjusted. The angle-adjusted spring can be directly clamped and mounted on a product by a mounting clamp or a mechanical arm or other mechanisms; the utility model belongs to the technical field of automation equipment.

Description

Technical Field

[0001] This utility model belongs to the technical field of automation equipment, and in particular relates to a keyboard spring flipping mechanism. Background Technology

[0002] To save space and prevent springs from tangling, springs (especially torsion springs or extension springs) can be stored at a specific angle. However, if these springs are to be installed at another angle, their orientation must be reset or adjusted before assembly. Utility Model Content

[0003] The purpose of this invention is to provide a keyboard spring flipping mechanism to address the technical deficiencies described in the background section.

[0004] The keyboard spring flipping mechanism includes:

[0005] The base has a bearing connecting it to the flipping block. The top surface of the flipping block has a placement groove. A cylinder is located below one side of the flipping block. The cylinder drives a pusher head to push one side of the flipping block upward.

[0006] The material preparation area is used to place springs to be installed;

[0007] The transport module is used to transport and place the springs in the preparation area into the placement slot, so that the cylinder-driven pusher can push the flipping block to flip up one side, thereby causing the springs in the placement slot to flip to an angle that can be installed in the installation area.

[0008] Based on the aforementioned technical solution, the present invention achieves the following beneficial effects:

[0009] 1. To save space when placing products and to prevent springs from getting tangled, springs are stored in the preparation area at a specific angle. When springs stored at one angle need to be installed on the product at another angle, the springs in the preparation area can be moved and placed into the placement slot by the handling module. Then, the cylinder drives the pusher to push the flipping block to flip up one side, causing the spring in the placement slot to flip to an angle that can be installed in the installation area. This resets or adjusts the angle of the spring so that the installation fixture or robot can directly clamp the adjusted spring and install it onto the product.

[0010] 2. When loading springs that are stored haphazardly, the springs in the preparation area can be moved and placed into the placement slot by the transport module. Then, the cylinder drives the pusher to push one side of the flipping block upward, thereby causing the spring in the placement slot to flip to an angle that can be installed in the installation area, thus realizing the reset or adjustment of the spring angle.

[0011] To further optimize the above technical solutions, they can be combined with one or more of the following implementation methods without conflict.

[0012] In some embodiments, the base is equipped with a tension spring connected to one side of the flipping block. After the spring in the placement slot is moved to the installation area for installation, the cylinder drives the push head to reset, and the tension spring is used to pull the flipping block to reset.

[0013] Based on the aforementioned technical solution, the handling module can place the next spring into the placement slot for flipping, thereby improving the flipping efficiency for a large batch of springs.

[0014] In some embodiments, one side of the bottom wall of the flipping block is provided with a relief arc surface for contacting the pusher head;

[0015] Based on the aforementioned technical solution, the friction or resistance between the pusher and the flipping block is reduced during the period when the tension spring pulls the flipping block to reset and during the period when the cylinder drives the pusher to reset, thereby improving the lifespan of the placement block and the pusher.

[0016] In some embodiments, a limiting surface is provided on the other side of the bottom wall of the flipping block so that the limiting surface contacts the base after the tension spring pulls the flipping block to reset.

[0017] Based on the aforementioned technical solution, during the resetting of the flip block by the tension spring and after the resetting of the push head driven by the cylinder, the tension of the tension spring is avoided from being applied to the push head, thereby reducing the load on the cylinder.

[0018] In some embodiments, the keyboard spring flipping mechanism further includes a transfer module, which drives a drive block away from the preparation area. A base is mounted on the drive block so that after the transport module places the spring in the placement slot, the transfer module drives the drive block to move the spring away from the preparation area.

[0019] Based on the aforementioned technical solution, since the transfer module drives the drive block to move the spring away from the material preparation area, there is sufficient space around the base to allow the installation mechanism to easily remove the spring from the placement slot.

[0020] In some implementations, limit buffers that contact the drive block are installed at both ends of the transfer module;

[0021] Based on the aforementioned technical solution, when the transfer module drives the drive block away from the material preparation area or resets, the drive block can accurately reach the set position, thereby enabling the installation mechanism to stably remove the spring from the placement slot and the transport module to stably place the spring into the placement slot.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, this specific embodiment will be described in further detail with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown in the figure, this specific embodiment provides a keyboard spring flipping mechanism, which includes a material preparation area 4, a transfer module 5, a base 1, and a transport module.

[0031] Preparation area 4 refers to the place where torsion springs to be installed are placed, which can be a material tray or packaging box, etc.

[0032] The transfer module 5 is driven by a drive block 51 located away from the material preparation area 4. The transfer module 5 can be a lead screw module, a cylinder 3 module, or a transmission belt module, etc., that can drive the drive block 51 away from the material preparation area. Limiting buffers 52 that contact the drive block 51 are installed at both ends of the transfer module 5.

[0033] The base 1 is mounted on the drive block 51, and the base 1 is connected to the flip block 2 by a bearing. The top surface of the flip block 2 is provided with a placement groove 21. A cylinder 3 is provided on one side of the flip block 2. The cylinder 3 drives a push head 31 for pushing one side of the flip block 2 to flip up. One side of the bottom wall of the flip block 2 is provided with a relief arc surface 22 for contacting the push head 31.

[0034] The base 1 is equipped with a tension spring 11 connected to one side of the flip block 2. The other side of the bottom wall of the flip block 2 is provided with a limiting surface 23. After the tension spring 11 pulls the flip block 2 to reset, the limiting surface 23 contacts the base 1.

[0035] The transport module can be a robotic arm or a fixture module capable of movement along the xyz axes. The transport module is used to transport the springs from the preparation area 4 into the placement slot 21, so that the cylinder 3 drives the pusher 31 to push one side of the flipping block 2 upwards, causing the spring in the placement slot 21 to flip to an angle suitable for installation in the mounting area. The mounting area refers to the location where the spring is to be installed, that is, the location in the keyboard where the torsion spring needs to be installed.

[0036] The following is a description of the operation of a keyboard spring flipping mechanism as described in this specific embodiment.

[0037] The transport module transports the springs in the preparation area 4 and places them in the placement slot 21. Then, the transfer module 5 drives the drive block 51 to move the springs away from the preparation area 4. Next, the cylinder 3 drives the push head 31 to push one side of the flipping block 2 upwards, moving the placement slot 21 to an angle suitable for installation in the mounting area. Then, the mounting mechanism removes the springs from the placement slot 21. The mounting mechanism can be another robotic arm or a clamping module capable of moving along the xyz axes, etc., to remove the springs from the placement slot 21. Next, the cylinder 3 drives the push head 31 to reset. At this time, the spring pulls the flipping block 2 to reset until the limiting surface 23 contacts the base 1. At this time, there is a gap between the push head 31 and the flipping block 2. Then, the transfer module 5 drives the drive block 51 to reset, allowing the transport module to transport the next spring from the preparation area 4 and place it in the placement slot 21.

[0038] During the process of the air supply cylinder 3 driving the pusher head 31 to push the flipping block 2 to flip up one side and move it into the placement slot 21 to an angle that can be installed in the installation area, the orientation angle of the spring can be selectively positioned by a vision positioning system (i.e., an industrial camera), thereby controlling the air volume of the cylinder 3, that is, controlling the stroke of the cylinder 3 driving the push.
