Description

Technical Field

[0001] The utility model relates to the field of instrument repair, in particular to a glue application device for instrument repair. Background Technique

[0002] The repair of instruments and meters refers to the restoration of faulty or damaged instruments and meters using various tools so that they can work properly. Generally, there are glass discs or transparent plastic discs on the instrument panel for staff to observe, which are connected to the instrument panel through adhesive. During repair, the glass disc or transparent plastic disc needs to be removed first. After the repair is completed, the residual glue needs to be cleaned up, and then glue is applied again and the glass disc or transparent plastic disc is reinstalled on the instrument panel.

[0003] Traditional glue application devices require staff to apply glue along the glue application track of the instrument relying on experience, with a high probability of applying the glue crooked, and it is difficult to control the uniformity of glue application for instruments of different sizes. Content of the Utility Model

[0004] In order to overcome the shortcomings that traditional glue application devices require staff to apply glue along the glue application track of the instrument relying on experience, with relatively low glue application accuracy, and it is difficult to control the uniformity of glue application for instruments of different sizes, the utility model provides a glue application device for instrument repair that can align the instrument, improve the accuracy of glue application, and can adjust the radius of the glue application movement track according to the instrument size by the glue outlet head to adapt to instruments of various sizes.

[0005] The technical solution is as follows: A glue application device for instrument repair includes a chassis. Two positioning frames are slidably connected to the chassis. The two positioning frames are symmetrically arranged. A threaded rod is rotatably connected to the chassis. The threaded rod is threadedly connected to the two positioning frames. One end of the threaded rod is fixedly connected with a rotating handle.

[0006] As an improvement of the above solution, it further includes a support frame. The support frame is fixedly connected to the top of the chassis. A motor is provided on the support frame. The output shaft of the motor passes through the support frame. A guide frame is fixedly connected to the support frame. The guide frame is located below the motor. A guide groove is opened on the guide frame of the support frame. Two guide posts are slidably connected in the guide groove of the guide frame. The two guide posts are symmetrically arranged. An installation frame is fixedly connected between the two guide posts. The installation frame is located below the guide frame. The output shaft of the motor is fixedly connected to the installation frame.

[0007] As an improvement of the above solution, it further includes a sliding frame. The sliding frame is slidably connected to the installation frame. A first spring is provided between the sliding frame and the installation frame. A glue outlet head is provided on one side of the sliding frame.

[0008] As an improvement to the above solution, it further includes a limit frame. The limit frame is slidably connected to the bottom frame. A card slot is opened in the upper part of the limit frame. An inclined surface is provided on the upper part of the limit frame. A second spring is provided between the limit frame and the bottom frame. A contact frame is fixedly connected to one side of the sliding frame close to the glue outlet head. The contact frame is located in the card slot in the upper part of the limit frame. The limit frame catches the contact frame, and the contact frame contacts the inclined surface on the limit frame.

[0009] As an improvement to the above solution, it further includes rollers. The rollers are rotatably connected to the lower part of the contact frame.

[0010] The utility model has the following advantages: 1. The instrument to be glued is placed on the bottom frame by the staff, and then the rotary handle is rotated. The rotation of the rotary handle drives the threaded rod to rotate. Under the action of the thread, the two positioning frames are driven to move horizontally in the direction of approaching each other to align the instrument, improving the accuracy of gluing.

[0011] 2. The staff pushes the limit frame in the direction away from the contact frame. The limit frame no longer catches the contact frame. The first spring will rebound and drive the sliding frame to move in the direction away from the limit frame. The movement of the sliding frame drives the glue outlet head to move in the direction away from the limit frame. The movement of the glue outlet head drives the contact frame to move in the direction away from the limit frame. When the contact frame moves to the position in contact with the instrument and no longer moves, at this time, the glue outlet head is above the position where the instrument needs to be glued, enabling the glue outlet head to adjust the radius of the gluing movement trajectory according to the size of the instrument and adapting to instruments of various sizes.

[0017] The technical solution will be further described below in conjunction with specific embodiments. It should be noted that: The words indicating directions such as up, down, left, and right in this article are only in terms of the positions of the shown structures in the corresponding drawings. The serial numbers assigned to the components in this article, for example: first, second, etc., are only used to distinguish the described objects and do not have any sequential or technical meanings. And as used in this application, terms such as: connection, coupling, unless otherwise specified, all include direct and indirect connection (coupling).

[0018] Embodiment 1: A glue application device for instrument repair, as Figures 1-4 shown, includes a chassis 1. Two positioning frames 2 are slidably connected to the chassis 1. The two positioning frames 2 are symmetrically arranged and are used to position the instrument. A threaded rod 3 is rotatably connected to the chassis 1. The threaded rod 3 is threadedly connected to the two positioning frames 2. The threaded rod 3 is used to drive the two positioning frames 2 to move. One end of the threaded rod 3 is welded with a rotary handle 4, and the rotary handle 4 is used to drive the threaded rod 3.

[0019] It further includes a support frame 5. The support frame 5 is bolted to the top of the chassis 1. A motor 6 is provided on the support frame 5. The support frame 5 is used to mount the motor 6. The output shaft of the motor 6 passes through the support frame 5. A guide frame 7 is fixedly connected to the support frame 5. The guide frame 7 is located below the motor 6. A guide groove is formed in the guide frame 7. Two guide posts 8 are slidably connected in the guide groove of the guide frame 7. The two guide posts 8 are symmetrically arranged. The guide frame 7 is used to guide the guide posts 8. An installation frame 81 is fixedly connected between the two guide posts 8. The installation frame 81 is located below the guide frame 7. The output shaft of the motor 6 is fixedly connected to the installation frame 81.

[0020] It further includes a sliding frame 9. The sliding frame 9 is slidably connected to the installation frame 81. A first spring 10 is provided between the sliding frame 9 and the installation frame 81. A glue outlet head 11 is provided on one side of the sliding frame 9. The sliding frame 9 is used to drive the glue outlet head 11 to move.

[0021] It further includes a limit frame 12. The limit frame 12 is slidably connected to the chassis 1. A card slot is formed in the upper part of the limit frame 12. An inclined surface is provided on the upper part of the limit frame 12. A second spring 13 is provided between the limit frame 12 and the chassis 1. A contact frame 14 is fixedly connected to the side of the sliding frame 9 close to the glue outlet head 11. The contact frame 14 is located in the card slot in the upper part of the limit frame 12. The limit frame 12 catches the contact frame 14, and the contact frame 14 will contact the inclined surface on the limit frame 12.

[0022] It further includes a roller 15. The lower part of the contact frame 14 is connected with the roller 15 through a bearing, and the roller 15 is used to reduce the friction between the contact frame 14 and the instrument.

[0023] Initially, the limit frame 12 holds the contact frame 14 in place, and the first spring 10 is in a stretched state. The staff places the instrument to be caulked on the base frame 1, and then rotates the rotary handle 4. The rotation of the rotary handle 4 drives the threaded rod 3 to rotate. Under the action of the thread, the two positioning frames 2 move horizontally towards each other to align the instrument, improving the accuracy of caulking. When the two positioning frames 2 move to the positions where they both contact the instrument, the staff stops rotating the rotary handle 4 and pushes the limit frame 12 away from the contact frame 14. The second spring 13 is compressed, and the limit frame 12 no longer holds the contact frame 14. The first spring 10 will rebound and drive the sliding frame 9 to move away from the limit frame 12. The movement of the sliding frame 9 away from the limit frame 12 drives the glue outlet head 11 to move away from the limit frame 12. The movement of the glue outlet head 11 away from the limit frame 12 drives the contact frame 14 to move away from the limit frame 12. When the contact frame 14 moves to the position where it contacts the instrument and stops moving, the glue outlet head 11 is above the position of the instrument to be caulked. Through the above operations, the radius of the caulking movement trajectory of the glue outlet head 11 can be adjusted according to the size of the instrument, and it can adapt to instruments of various sizes. Subsequently, the staff releases the limit frame 12, and the second spring 13 will rebound and drive the limit frame 12 to reset. Then, the motor 6 is started to rotate, and the glue outlet head 11 caulks. The rotation of the motor 6 drives the mounting frame 81 to rotate through the output shaft. The rotation of the mounting frame 81 drives the two guide posts 8 to slide along the guide grooves on the guide frame 7, reducing the probability of jitter when the mounting frame 81 rotates and improving the stability of the mounting frame 81 during rotation. The rotation of the mounting frame 81 drives the sliding frame 9 to rotate. The rotation of the sliding frame 9 drives the glue outlet head 11 to rotate to caulk the position of the instrument to be caulked. The rotation of the glue outlet head 11 drives the contact frame 14 to rotate along the side of the instrument. After the glue outlet head 11 rotates one circle, the caulking is completed. The staff turns off the motor 6 and pulls the contact frame 14 towards the limit frame 12. The movement of the contact frame 14 towards the limit frame 12 drives the glue outlet head 11 to move towards the limit frame 12. The movement of the glue outlet head 11 towards the limit frame 12 drives the sliding frame 9 to move towards the limit frame 12. The first spring 10 is stretched. The contact frame 14 continues to move towards the limit frame 12 and contacts the inclined surface on the limit frame 12, squeezing the limit frame 12 away from the contact frame 14. The second spring 13 is compressed. The contact frame 14 continues to move towards the limit frame 12 and disengages from the inclined surface on the limit frame 12. The second spring 13 will rebound and drive the limit frame 12 to reset. The contact frame 14 returns to the card slot of the limit frame 12 again, and the limit frame 12 holds the contact frame 14 again. Then, the staff rotates the rotary handle 4 in the reverse direction to reset. The reverse rotation of the rotary handle 4 drives the threaded rod 3 to rotate in the reverse direction. Under the action of the thread, the two positioning frames 2 move horizontally away from each other to reset, facilitating the staff to take away the caulked instrument and carry out the next work.

[0024] When the contact holder 14 rotates along the side of the instrument, the roller 15 reduces the friction between the contact holder 14 and the side of the instrument, enabling the contact holder 14 to rotate more smoothly along the side of the instrument.
