Description

Technical Field

[0001] This utility model relates to the field of positioning and adjusting devices, and in particular to a brush positioning device. Background Technology

[0002] Electronic products typically have a protective film adhering to their surface. After assembly, this protective film needs to be removed. Manually peeling the film leaves fingerprints and other marks on the product surface. Therefore, existing film-peeling mechanisms use robotic arms and grippers to peel the film, and a brush cleans away any residual film on the grippers.

[0003] However, in the existing film-tearing mechanism, when the brushes clean the grippers, the grippers pass through the middle of the two sets of brushes and are cleaned by the brushes. There is a chance that the brushes will move up and down with the grippers, making it difficult for the brushes to effectively clean the waste film. Because the brushes are relatively parallel, the grippers press the brushes down, and the elastic force of the brushes is upward. When the grippers open, there is a chance that the residual waste film on the grippers will be bounced onto the surrounding processing equipment, resulting in contamination and difficulty in cleaning. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that waste film is easily bounced back when the brush cleans the gripper in the prior art, thereby providing a brush positioning device.

[0005] To solve the above-mentioned technical problems, this utility model provides a brush positioning device, comprising:

[0006] An adjustment mechanism, comprising: a first adjustment component and a second adjustment component, wherein the angle between the centerlines of the first adjustment component and the second adjustment component is an acute angle;

[0007] The first adjustment component and the second adjustment component both include: a support tube, a support frame, a screw, and a rotating component. The support frame is movably disposed on the support tube and is located on opposite sides of the support tube. The screw is rotatably connected to the support tube and threadedly connected to the bracket. The support frame is rotatably connected to the support tube through the rotating component. The support frame is used to install the brush to be adjusted.

[0008] In one embodiment of the present invention, the support frame includes: a first support part, a connecting part, and a second support part connected in sequence, wherein the first support part and the second support part are respectively located on opposite sides of the support tube, and the two ends of the connecting part are respectively connected to the first support part and the second support part.

[0009] In one embodiment of the present invention, the second support is disposed on the side close to the first adjustment component and the second adjustment component, and the second support is used to install the brush to be adjusted.

[0010] In one embodiment of the present invention, the first support portion has a threaded hole and a coaxial threaded sleeve, and the screw is adapted to the threaded hole and the threaded sleeve.

[0011] In one embodiment of the present invention, the support tube is provided with a rotating shaft, and the second support parts of the first adjustment component and the second adjustment component are both connected to hinge parts on the side of their proximity. The second support parts are rotatably connected to the support tube via the rotating shaft.

[0012] In one embodiment of this utility model, a bearing seat is fixedly connected inside the support tube, and the end of the screw passes through the support tube and is rotatably connected to the support tube through the bearing seat.

[0013] In one embodiment of this utility model, the screw is also adapted to be fitted with a nut, which can abut against the first support portion.

[0014] In one embodiment of the present invention, the second support portion is detachably mounted with a support base.

[0015] In one embodiment of the present invention, the support base includes: a first plate and a second plate connected together, the included angle between the planes containing the first plate and the second plate is an acute angle, the first plate is detachably mounted on the second support portion, and the second plate is used to detachably mount the brush to be adjusted.

[0017] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0018] The brush positioning device of this utility model adjusts the angle of two sets of brushes by setting a first adjustment component and a second adjustment component, so that the two sets of brushes are kept facing each other and tilted downwards. When the gripper passes through the middle of the two sets of brushes, the brushes on both sides form a V-shape with the brushes facing downwards, thereby increasing the probability of film removal and preventing waste film from rebounding upwards to the surrounding processing equipment and causing pollution. At the same time, it can centrally clean up waste film. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0026] Example

[0027] Reference Figures 1-4 As shown, a brush positioning device of this utility model includes:

[0028] An adjustment mechanism, comprising: a first adjustment component and a second adjustment component, wherein the angle between the centerlines of the first adjustment component and the second adjustment component is an acute angle;

[0029] The first adjustment component and the second adjustment component both include: a support tube 1, a support frame 2, a screw 5, and a rotating component. The support frame 2 is movably disposed on the support tube 1 and is located on opposite sides of the support tube 1. The screw 5 is rotatably connected to the support tube 1 and threadedly connected to the bracket. The support frame 2 is rotatably connected to the support tube 1 through the rotating component. The support frame 2 is used to install the brush to be adjusted.

[0030] The brush positioning device of this utility model allows for the adjustment of the brushes after they are installed on the support frame 2. The first and second adjusting components are rotated to make the two sets of brushes tilted relative to each other, and the angle of the brushes in space can be adjusted. If the brush needs to be closer to the workpiece surface, the rotatable screw 5 can be used to rotate the support frame 2 around the rotating component as a hinge point. If the brush tilt angle needs to be adjusted, the screw 5 can be rotated. The screw 5 is rotatably connected to the support tube 1 and engages with the support frame 2 through a thread, converting the rotational motion into linear displacement of the support frame 2. This, in conjunction with the rotating component, causes the support frame 2 to rotate around the support tube 1.

[0031] Reference Figure 1 As shown, the support frame 2 includes a first support part 21, a connecting part 22, and a second support part 23 connected in sequence. The first support part 21 and the second support part 23 are located on opposite sides of the support tube 1, and the two ends of the connecting part 22 are connected to the first support part 21 and the second support part 23, respectively. The first support part 21 is located on one side of the support tube 1 and mainly undertakes the connection function with the screw 5. It has sufficient thickness and strength to transmit the adjustment force and ensure the reliability of the connection. The second support part 23 is located on the other side of the support tube 1 and is directly used to install the brush to be adjusted. Its structure needs to be adapted to the brush installation requirements, such as opening mounting holes and slots. The connecting part 22 serves as an intermediate transition structure, rigidly connecting the first and second support parts 23. It can be welded or integrally formed to form a gate-shaped structure that spans the support tube 1, ensuring that the movement of the two support parts is synchronized. When the screw 5 drives the first support part 21 to move linearly, the connecting part 22 transmits the movement to the second support part 23, realizing the synchronous displacement of the brush.

[0032] Reference Figures 3-4 As shown, the second support part 23 is located on the side close to the first adjustment component and the second adjustment component, and the second support part 23 is used to install the brush to be adjusted. When the screw 5 of the first adjustment component rotates, its first support part 21 moves along the screw 5, and drives the second support part 23 to move towards the middle area through the connecting part 22; similarly, the rotation of the screw 5 of the second adjustment component drives its second support part 23 to move towards the middle area synchronously, which can adjust the tilt angle of the brush and accurately adapt to the surface of the workpiece to be cleaned.

[0033] Reference Figure 4 As shown, the first support portion 21 has a threaded hole and a coaxial threaded sleeve 9. The screw 5 is adapted to the threaded hole and the threaded sleeve 9. The wear resistance of the threaded sleeve 9 is superior to that of the base material of the first support portion 21, such as aluminum alloy, which can effectively reduce thread wear when the screw 5 rotates and extend the connection life. At the same time, the coaxiality requires ensuring the fitting accuracy between the screw 5 and the threaded sleeve 9 to avoid jamming or abnormal wear caused by eccentricity. The long engagement length increases the connection strength and can withstand greater adjustment force.

[0034] Reference Figure 3As shown, the support tube 1 is equipped with a rotating shaft 3. Hinges 24 are connected to the adjacent sides of the second support parts 23 in both the first and second adjustment components. The second support parts 23 are rotatably connected to the support tube 1 via the rotating shaft 3. When the brush tilt angle needs to be adjusted, an external force is applied to rotate the second support part 23 around the rotating shaft 3. At this time, the first support part 21 will move adaptively along the axis of the screw 5. Because the support frame 2 is an integral structure, structural stability is ensured. For example, if the brush needs to contact the workpiece at a 45° angle, the linear position of the second support part 23 can be adjusted via the screw 5, causing the second support part 23 to rotate to 45° around the rotating shaft 3 via the hinge 24, thus achieving brush posture adjustment. Thread self-locking is achieved after adjustment.

[0035] A bearing seat 10 is fixedly connected inside the support tube 1. The end of the screw 5 passes through the support tube 1 and is rotatably connected to the support tube 1 via the bearing seat 10. To ensure the smooth rotation and axial stability of the screw 5, the bearing seat 10 is fixed inside the support tube 1, and the end of the screw 5 passes through the support tube 1 and is rotatably connected to the support tube 1 via the bearing seat 10. A rolling bearing is installed inside the bearing seat 10. The rolling bearing converts the sliding friction of the screw 5 into rolling friction, significantly reducing rotational resistance and preventing jamming during long-term use. It also restricts the movement of the screw 5 along the axis, ensuring that the thread engagement between the screw 5 and the support frame 2 is always reliable. If the screw 5 moves axially, it will cause changes in the thread engagement length or even disengagement, resulting in failure of the adjustment function.

[0036] Reference Figure 4 As shown, the screw 5 is also fitted with a nut 4, which abuts against the first support part 21. To prevent the screw 5 from reversing due to vibration after adjustment, a matching nut 4 is fitted onto the screw 5. The nut 4 abuts against the first support part 21. After adjusting to the appropriate position, the nut 4 is rotated to abut against the first support part 21, and friction prevents the screw 5 from reversing. When readjustment is required, the nut 4 is rotated in the opposite direction to disengage it. This effectively prevents the screw 5 from reversing, ensuring the stability of the support frame 2, and is especially suitable for vibration scenarios. The detachable design allows for flexible adjustment without additional tools, and an elastic washer can be configured to enhance locking reliability.

[0037] Reference Figure 2 As shown, in some embodiments, the second support portion 23 is detachably mounted with a support base 6. To improve the versatility of the device and adapt to different brush types, the support base 6 is detachably mounted on the second support portion 23.

[0038] The support base 6 includes a first plate 61 and a second plate 63 connected together. The included angle between the planes containing the first plate 61 and the second plate 63 is an acute angle. The first plate 61 is detachably mounted on the second support part 23, and the second plate 63 is used to detachably mount the brush to be adjusted. To expand the brush posture adjustment range and adapt to inclined working surfaces, this solution designs the support base 6 as an angular structure: including a first plate 61 and a second plate 63 connected together, with an acute angle between their planes. The first plate 61 is detachably mounted on the second support part 23, and the second plate 63 mounts the brush. The connection method is detachable mounting. Angle pre-configuration: By changing the included angle of the angular structure, the mounting angle of the brush can be directly adjusted. For example, if the included angle is 60°, when the first plate 61 is installed horizontally, the second plate 63 is tilted at 60°, and the brush can contact the workpiece at a 60° angle. If the angle needs to be adjusted, only the support base 6 with a different included angle needs to be replaced, without changing the structure of the adjustment component. The detachable design is compatible with a variety of brushes, enhancing versatility; the 6-module support base reduces replacement costs; and multiple connection methods adapt to different usage scenarios.

[0039] Both the first plate 61 and the second plate 63 have oblong holes 62 and multiple positioning holes 64 spaced apart along their length. The second support part 23 or the brush to be adjusted has mounting holes adapted to the oblong holes 62 or positioning holes 64. To achieve fine-tuning and precise positioning of the installation position, this solution provides oblong holes 62 along the length of the first and second plates 63 of the support base 6, and multiple positioning holes 64 spaced apart. The second support part 23 / brush has matching mounting holes, which can increase the stroke for extended installation and adjustment. The oblong holes 62 provide fine-tuning flexibility to adapt to different workpiece sizes; the positioning holes 64 ensure installation accuracy and avoid operational errors; the combined design improves installation efficiency and eliminates the need for additional measuring tools.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
