Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to an assembly and splicing auxiliary device for plastic product processing. Background Technology

[0002] This plastic product assembly and splicing auxiliary device ensures stability and precision during the splicing process. The device features a modular structure and flexible grippers, adaptable to plastic parts of various shapes and sizes (50-500mm), such as housings, pipes, or irregularly shaped components. Core functions include a pneumatic / electric quick-locking mechanism for damage-free clamping; a magnetic or vacuum adsorption base for enhanced stability; and a laser-assisted alignment system for precise marking of the joining positions. The device supports manual or PLC control modes and can be integrated into automated production lines for use with hot-melt, ultrasonic welding, or adhesive bonding processes. Its high-rigidity frame and shock-resistant design effectively reduce operational vibration, ensuring splicing tolerances of ≤0.2mm, while the quick-change fixture design significantly shortens changeover time. It is suitable for high-precision assembly of plastic parts in industries such as home appliances, automobiles, and medical devices, significantly improving production efficiency and product yield.

[0003] When using existing equipment, the angle of the placement seat is generally fixed. The angle of plastic products usually depends on manual adjustment, which requires repeated tightening and loosening of the clamps or replacement of the positioning blocks, resulting in long changeover time and affecting the production cycle. Complex angles (such as inclined planes and multi-directional splicing) require multiple trials and errors, increasing debugging time. At the same time, frequent manual adjustment of the angle can easily lead to worker fatigue, especially for large-sized workpieces (such as plastic boxes), making handling and positioning difficult.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] An assembly and splicing auxiliary device for processing plastic products includes a fixed base 1 with an installation groove 2, a connecting rod 3 rotatably connected inside the installation groove 2, a placement seat 4 fixedly connected to the upper end of the connecting rod 3, and the placement seat 4 rotatably connected to the fixed base 1.

[0026] The fixed base 1 has a limiting component 5 inside for limiting the placement base 4;

[0027] The placement base 4 has multiple circularly distributed grooves 6 inside, and each groove 6 is equipped with a clamping component 7 for fixing the plastic product.

[0028] The limiting assembly 5 includes a rotating rod 51 rotatably connected inside the fixed base 1. A torsion spring 52 is sleeved on the outer side of the rotating rod 51. A rotating disk 53 is fixedly connected to one end of the rotating rod 51. Two symmetrically distributed limiting plates 54 are fixedly connected to the side wall of the rotating disk 53. Two evenly distributed fixing plates 55 are fixedly connected to the side wall of the fixed base 1. One of the fixing plates 55 contacts the limiting plate 54. A lifting plate 56 is provided at the upper end of the rotating disk 53. A fixing rod 57 is slidably connected inside the lifting plate 56. The fixing rod 57 is fixedly connected to the fixed base 1. A limiting block 58 is fixedly connected to the upper end of the lifting plate 56. A plurality of annularly distributed limiting holes 59 are opened at the bottom of the placement seat 4. One of the limiting holes 59 is slidably connected to the limiting block 58. The fixed base 1 is slidably connected to the lifting plate 56 and the limiting block 58 respectively.

[0029] For example, the rotating disk 53 is controlled to rotate by the limiting plate 54 away from the fixed seat 1. The limiting plate 54, together with the fixed plate 55, limits the rotating disk 53 so that the rotating disk 53 can only rotate half a turn. That is, both ends of the rotating disk 53 near the rotating rod 51 and away from the rotating rod 51 can contact the lifting plate 56. After the rotating disk 53 rotates, it releases the support of the lifting plate 56, and the lifting plate 56 descends. When the lifting plate 56 rises and falls, the fixed rod 57 guides the lifting plate 56, and the limiting block 58 disengages from the limiting hole 59, releasing the limitation on the placement seat 4, which facilitates the adjustment of the angle of the placement seat 4. After the limiting plate 54 is released, the rotating disk 53 is driven to reset under the action of the rotational force of the torsion spring 52. The rotating disk 53 drives the lifting plate 56 to rise, so that the limiting block 58 is locked inside the limiting hole 59 at different positions, fixing the placement seat 4 at different angles.

[0030] The clamping assembly 7 includes multiple sliders 71 that are slidably connected inside multiple slide grooves 6. Each slider 71 has two symmetrically distributed fixing bolts 72 inside. Each fixing bolt 72 contacts the placement seat 4. Each slider 71 has a trapezoidal block 73 fixedly connected to its upper end. Each trapezoidal block 73 has a connecting bolt 74 inside. One end of the connecting bolt 74 is fixedly connected to a limiting plate 75. The outer side of the connecting bolt 74 is threaded with a clamping block 76. The clamping block 76 contacts the trapezoidal block 73 and the limiting plate 75. A rubber plate 77 is fixedly connected to the side wall of the clamping block 76. Each trapezoidal block 73 has two symmetrically distributed limiting frames 78 on its side wall. Each limiting frame 78 contacts the connecting bolt 74. Each trapezoidal block 73 has a lifting groove inside for the lifting of the connecting bolt 74.

[0031] For example, loosening the fixing bolt 72 allows the slider 71 to slide inside the slide groove 6. By moving the slider 71 to different positions inside the slide groove 6, different plastic products can be clamped. At the same time, multiple clamping blocks 76 can move at different distances to fix plastic products of different shapes. By adjusting the angle of the connecting bolt 74, a threaded movement occurs between the connecting bolt 74 and the clamping block 76, controlling the depth change of the end of the connecting bolt 74 in the clamping block 76. This allows the clamping block 76 to slide on the inclined side of the trapezoidal block 73, facilitating the clamping block 76 and the rubber plate 77 to clamp the plastic product. The limiting frame 78 limits the connection bolt 74.

[0032] Working principle: When using this utility model, the plastic product is placed on the upper end of the placement seat 4, and the fixing bolt 72 is loosened to allow the slider 71 to slide inside the slide groove 6. Different plastic products can be clamped at different positions inside the slide groove 6. At the same time, multiple clamping blocks 76 can move at different distances to fix plastic products of different shapes. By adjusting the angle of the connecting bolt 74, a threaded movement occurs between the connecting bolt 74 and the clamping block 76, controlling the depth change of the end of the connecting bolt 74 in the clamping block 76, so that the clamping block 76 can slide on the inclined side of the trapezoidal block 73, and the clamping block 76 and the rubber plate 77 can clamp the plastic product. The limiting frame 78 limits the connecting bolt 74. When the limiting block 58 is inserted into the limiting hole 59, there is a clear "click" sound and feel, which avoids accidental operation due to not locking.

[0033] When the angle of the plastic product needs to be adjusted, the rotating disk 53 is controlled to rotate by the limiting plate 54 away from the fixed seat 1. The limiting plate 54, together with the fixed plate 55, limits the rotating disk 53, so that the rotating disk 53 can only rotate half a turn. That is, both ends of the rotating disk 53 near the rotating rod 51 and away from the rotating rod 51 can contact the lifting plate 56. After the rotating disk 53 rotates, it releases the support of the lifting plate 56, and the lifting plate 56 descends. When the lifting plate 56 rises and falls, the fixed rod 57 guides the lifting plate 56, and the limiting block 58 disengages from the limiting hole 59, releasing the limitation on the placement seat 4, which facilitates the adjustment of the angle of the placement seat 4. After the limiting plate 54 is released, the rotating disk 53 is driven to reset under the action of the rotational force of the torsion spring 52. The rotating disk 53 drives the lifting plate 56 to rise, so that the limiting block 58 is locked inside the limiting hole 59 at different positions, fixing the placement seat 4 at different angles.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
