Description

Technical Field

[0001] This utility model relates to the field of transfer mechanism technology, and in particular to a plate-shaped material clamping mechanism. Background Technology

[0002] In existing technologies, the horizontal transfer of sheet-like materials typically employs adsorption transfer. This involves using a fan mechanism to adsorb the sheet-like material from above, then rotating and placing it in a predetermined position. Because the adsorption is from top to bottom, it allows for installation space below the sheet-like material. However, this structure often occupies a relatively large amount of space.

[0003] The clamping and transfer method requires lifting the plate-shaped material in contact with the bottom surface to a certain extent before allowing the clamping component to enter, which is a difficult process. Utility Model Content

[0004] The purpose of this invention is to provide a clamping mechanism for plate-shaped materials that is convenient to clamp and takes up little space.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plate-shaped material clamping mechanism, including a transverse rail, a moving mechanism on the transverse rail, and a fixed platform on the moving mechanism; a longitudinal slide rail on the fixed platform, a sliding chassis on the longitudinal slide rail, a longitudinal groove at the bottom of the front end of the sliding chassis, and a longitudinal groove extending downward through the longitudinal groove at the top of the rear end, a limiting block slidingly disposed within the longitudinal groove, a push plate at the lower end of the limiting block, and a push ramp at the front end of the push plate; a rack extending rearward from the rear side of the limiting block, with the rack having a denser front end and a sparser rear end; a support base at the rear end of the fixed platform, a drive motor on the support base, and a gear meshing with the rack on the rotating shaft of the drive motor; vertical blocks on both sides of the sliding chassis, with clamping components disposed on the vertical blocks; and an electric push rod on the fixed platform, the end of which is connected to the vertical block.

[0006] The rack is further configured such that the ratio of its density to its spacing is 1:2, with no transition between the density and spacing.

[0007] The moving mechanism is further configured such that: a base is provided, a fixed platform is mounted on the base, and a transverse push rod is provided at one end of the transverse rail, the transverse push rod being connected to the base.

[0008] A further configuration is provided: a lower groove is provided on the push plate at the rear end of the push ramp, and the upper edge of the lower groove is flush with the upper edge of the sliding base.

[0009] In summary, this utility model has the following beneficial effects: by setting a movable and fast-forward pushing plate at the lower end of the sliding chassis, it is possible to easily scoop up plate-shaped materials, thereby relatively reducing space occupation and maintaining clamping stability.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings.

[0013] A plate-shaped material clamping mechanism, especially for clamping thin materials such as PCB boards, includes a transverse rail 1, which can be mounted on the ground. A moving mechanism 2 is mounted on the transverse rail 1. The moving mechanism includes a base 18, on which a fixed platform 3 is mounted. A transverse push rod 19 is mounted at one end of the transverse rail 1 and is connected to the base 18. The transverse push rod 19 is an electric push rod 16, which, when activated, causes the moving mechanism 2 to move along the extension direction of the transverse rail 1. Alternatively, the moving mechanism 2 can also achieve its movement on the transverse rail 1 through active control of the wheels on the moving mechanism 2. The electric push rod 16 solution is suitable for short strokes, while the active wheel control solution is suitable for long strokes. The active wheel control solution involves controlling the forward and reverse rotation of the motor; this technology is existing and will not be described further.

[0014] A longitudinal slide rail 4 is provided on the fixed platform 3, and a sliding chassis 5 is provided on the longitudinal slide rail 4. Vertical blocks 14 are provided on both sides of the sliding chassis 5. An electric push rod 16 is provided at the rear end of the fixed platform 3. The end of the electric push rod 16 is connected to the vertical block 14, so that when the electric push rod 16 is started, it can drive the sliding chassis 5 to move in the extension direction of the longitudinal slide rail 4.

[0015] A longitudinal groove 6 is provided at the bottom of the front end of the sliding chassis 5, and a longitudinal sliding groove 7 is provided above the sliding chassis 5, which is connected to the front end of the longitudinal groove 6. A limiting block 8 is slidably installed in the longitudinal sliding groove 7, and a push plate 9 located in the longitudinal groove 6 is provided at the lower end of the limiting block 8. A push ramp 10 is provided at the front end of the push plate 9.

[0016] A rack 11 extends rearward from the rear side of the limiting block 8. The rack 11 has denser teeth at the front end and sparser teeth at the rear end. A drive motor 12 is located at the rear end of the fixed platform 3. A gear 13 that meshes with the rack 11 is mounted on the rotating shaft of the drive motor 12. When the drive motor 12 starts, it pushes the rack 11 forward, thereby causing the push plate 9 to quickly scoop up the plate-shaped material. The ratio of the dense to sparse teeth on the rack 11 is 1:2, with no transition between the dense and sparse areas. That is, the front end of the rack 11 has normally spaced teeth, and the rear end (starting from the middle) has one tooth removed every other tooth.

[0017] A clamping component 15 is provided on the vertical block 14. The clamping component 15 is driven by a motor to rotate, just like conventional clamping, and works with the pushing ramp 10 on the push plate 9 to clamp.

[0018] In the above process, the drive motor 12 first drives the rack 11 to move forward. Due to the different spacing of the racks 11, the racks 11 will move faster at first, thereby pushing the push plate 9 out and scooping it under the plate-shaped material.

[0019] Then the drive motor 12 continues to push the rack 11 forward. At this time, the rack 11 enters the rear end of the rack 11, and the speed of the rack 11 slows down and remains stable, allowing the plate-shaped material to enter the sliding chassis 5 stably.

[0020] Then the clamping mechanism operates, cooperating with the sliding chassis 5 to clamp the plate-shaped material, and transports the material to the predetermined position under the action of the transverse rail 1 and the moving mechanism 2.

[0021] Once the predetermined position is reached, the clamping mechanism releases. The drive motor 12 rotates in the opposite direction, causing the sliding base 5 to move backward first, and then the push plate 9 to retract. During this process, since the front end of the plate-shaped material extends beyond the range of the sliding base 5 and the clamping assembly 15, the plate-shaped material will not retract with the sliding base or the push plate 9, that is, it will not remain on the sliding base 5.

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
