Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a double-sided clamping tray. Background Technology

[0002] In existing technologies, unidirectional clamping pallets are commonly used for material transport in the welding section of prismatic battery modules. These pallets, typically with a single-direction flow structure, are ill-suited for the flexible layout requirements of lateral and longitudinal flow within the production line, limiting their application in complex operating conditions. Furthermore, existing pallet structures often fail to consider the convenience of manual handling, requiring additional auxiliary equipment or operations during loading, unloading, and transfer connections, thus impacting overall production efficiency and automation integration. Therefore, there is an urgent need for a pallet structure that can achieve stable bidirectional clamping during transport, support multi-directional flow, and facilitate manual handling, thereby improving the automation level and operational reliability of battery module production lines.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 3 A double-sided clamping tray according to an embodiment of this utility model includes a base plate 100, which is typically made of sheet metal and is used to support workpieces and mount various functional components. A clamping mechanism 110 for clamping workpieces and a reference block for positioning the workpieces are provided on the base plate 100. The clamping mechanism 110 and the reference block appear in pairs and are arranged opposite each other, together forming a clamping station, namely the mounting position 111.

[0023] During operation, the operator or automated equipment places the workpiece 115 on the base plate 100, initially bringing one side close to or against the reference block. Then, the clamping mechanism 110 is activated, applying a pushing force to the workpiece 115, causing it to move towards the reference block until the other side is firmly in contact with it, thus clamping and positioning the workpiece 115. This relative clamping method ensures that the workpiece 115 is securely restrained between the clamping mechanism 110 and the reference block under the clamping force, effectively preventing displacement or loosening due to vibration, inertia, or other reasons during subsequent transportation or processing, significantly improving the reliability of the tooling fixture.

[0024] To facilitate smooth, low-resistance movement on the conveyor line, the outer periphery of the base plate 100 is provided with multiple guide wheels 103. These guide wheels 103 are preferably made of wear-resistant materials, such as nylon or bearing rollers, and are rotatably mounted on the sides of the base plate 100 via brackets or shafts. Correspondingly, guides are fixedly installed on both sides of the external conveyor line (e.g., the profile frame of a double-speed chain). The guides can be rails, guards, or simple guide strips. When the base plate 100 is placed on the conveyor line, a pad 102 is provided at the bottom of the base plate 100 to bear the weight, while the guide wheels 103 on the sides contact the guides on both sides of the conveyor line. When the conveyor line drives the pallet to move, the guide wheels 103 roll along the guides, thereby converting the sliding friction between the pallet and the fixed components of the conveyor line into rolling friction. This reduces the resistance when the pallet moves, making pushing or driving easier, reducing wear and noise caused by friction, and also providing guidance to prevent the pallet from deviating during transportation or colliding hard with the conveyor line.

[0025] It is understood that the clamping mechanism 110 can have various specific structures, such as manual quick clamps, pneumatic or electric push rods, etc. In this embodiment, the clamping mechanism 110 may include a reciprocating clamping plate 112. The clamping plate 112 is provided with preload by a spring 113 and is operated by a drive plate 114. The drive plate 114 can be moved manually or automatically (by actuating components such as cylinders or hydraulic cylinders) to achieve the clamping and opening actions.

[0026] It is understood that a certain gap 104 is maintained between the bottom of the clamping mechanism 110 and the upper surface of the base plate 100. In this embodiment, the height of the gap 104 is greater than 40mm, making it sufficient to accommodate an adult's fingers or palm. Therefore, the operator can directly grasp the space below the clamping mechanism 110 as an effective force point for transporting the pallet, thereby easily lifting and moving the entire base plate 100. This eliminates the need to add traditional handles to the sides of the pallet, simplifying the pallet structure, reducing cost and weight, and avoiding interference or snagging that protruding handles may cause in dense production line environments, thus improving equipment integration and the convenience of manual handling.

[0027] Understandably, at least two independent mounting positions 111 can be provided on the base plate 100. Each mounting position 111 is equipped with a complete clamping mechanism 110 and a reference block, enabling it to clamp two or more workpieces 115 simultaneously. This multi-station design allows a single base plate 100 to complete the transportation of multiple workpieces 115 in a single flow, greatly improving logistics efficiency. Multiple mounting positions 111 can be arranged side by side along the length or width of the base plate 100, and the specific layout can be flexibly designed according to the size of the workpiece and production cycle requirements.

[0028] To prevent the workpiece 115 from rotating in the plane, at least two clamping mechanisms 110 can be used. These two clamping mechanisms 110 can be arranged near two adjacent sidewalls of the workpiece 115. For example, one clamping mechanism 110 acts on the longitudinal side of the workpiece 115, and the other acts on its width side. When the two clamping mechanisms 110 operate simultaneously, they can apply pressure to the workpiece 115 from two perpendicular directions, and in conjunction with the corresponding reference blocks, achieve complete positioning of the workpiece 115 in the two-dimensional plane.

[0029] Furthermore, the reference block can be specifically divided into a first reference block 106 and a second reference block 107. The first reference block 106 is used to position a main reference surface (such as the long side) of the workpiece 115, while the second reference block 107 is used to position another adjacent reference surface (such as the short side). The first reference block 106 and the second reference block 107 are usually arranged at right angles, together forming an internal positioning angle. When the workpiece 115 is placed, its two adjacent sides are respectively abutted against the first reference block 106 and the second reference block 107, thereby quickly and accurately determining its position on the pallet.

[0030] To naturally create the clearance 104 between the clamping mechanism 110 and the base plate 100 for easy handling, an effective implementation involves placing a pad 105 on the mounting position 111 of the base plate 100. The pad 105 is a block structure with a certain height, fixed to the base plate 100 by screws or welding. Subsequently, the base of the clamping mechanism 110 is mounted on top of the pad 105, thus elevating the bottom of the clamping mechanism 110, naturally creating the required clearance 104 between its lower surface and the table surface of the base plate 100.

[0031] It is understandable that when the base plate 100 has two side-by-side mounting positions 111, the two mounting positions 111 can share a common first reference block 106 in the middle. Specifically, this shared first reference block 106 can be designed to have two opposing positioning surfaces, facing the left and right mounting positions 111 respectively. In this way, the two workpieces 115 can be placed back to back. This "back-to-back" layout saves space on the base plate 100, making the structure more compact, while also ensuring that the positioning references of the two workpieces 115 are consistent in the long side direction. In this embodiment, two back-to-back first reference blocks 106 can also be provided on the two side-by-side mounting positions 111 (e.g., Figure 1 (As shown).

[0032] Understandably, a recessed clearance 116 is provided on the top wall of the second reference block 107. The clearance 116 is a localized groove or sunken area. When the workpiece 115 is placed in position, part of its edge may be above the second reference block 107. At this time, the clearance 116 creates an additional vertical space between the edge of the workpiece 115 and the second reference block 107. The operator's or robot's fingers or grippers can more easily reach into the clearance 116 to hook or clamp the edge of the workpiece 115, thereby making the picking or placing operation easier and smoother, and avoiding interference with the reference block itself.

[0033] Understandably, multiple anti-collision blocks 101 can be installed around the perimeter of the base plate 100. The anti-collision blocks 101 are typically made of elastic, wear-resistant materials, such as polyurethane or rubber, and are fixed to the sidewalls of the base plate 100 by bolts or adhesive. The sidewalls of the anti-collision blocks 101 protrude from the metal perimeter of the base plate 100 itself. When the base plates 100 slightly collide with each other on the conveyor line due to inertia or continuous transport, the elastic surfaces of the anti-collision blocks 101 are the first to come into contact. The elastic material can effectively absorb collision energy, acting as a buffer, thereby protecting the metal structure of the base plate 100 from damage, while also reducing noise and extending the service life of the base plate 100.

[0034] Furthermore, multiple pads 102 are installed at the bottom of the base plate 100. The pads 102 are typically made of wear-resistant materials (such as high-molecular-weight polyethylene or metal inlays) with a smooth, flat lower surface. When the base plate 100 is stationary on the conveyor line, the lower surface of the pads 102 directly contacts the load-bearing surface of the conveyor line (such as the chain plates or guide rails of a double-speed chain), bearing the full weight of the base plate 100 and the workpiece 115. At this time, the rims of the side guide wheels 103 should maintain slight contact or a small gap with the side guides of the conveyor line, but should not bear the main vertical load. This design ensures the stability of the base plate 100 support while allowing the guide wheels 103 to focus on horizontal guidance and drag reduction, avoiding accelerated wear or deformation due to load.

[0035] To ensure accurate stopping and positioning of the base plate 100 at specific locations on the conveyor line for loading, unloading, processing, or inspection operations, a positioning sleeve 109 is embedded in the base plate 100. The positioning sleeve 109 is typically a robust metal sleeve, pressed or threaded into a specific position on the base plate 100. A precision positioning hole 108 is machined into the center of the positioning sleeve 109. At predetermined stop positions on the conveyor line, a positioning pin device driven by a cylinder or other power source is installed. When the base plate 100 is conveyed to this stop and initially stopped by a blocking mechanism (such as a blocking cylinder), the lifting cylinder actuates, driving the positioning pin upwards. The top of the positioning pin aligns with and inserts into the positioning hole 108 of the positioning sleeve 109 on the base plate 100. Through the tight fit between the pin and the hole, the position of the base plate 100 in the horizontal plane is accurately fixed, eliminating minor deviations caused by conveying gaps, thereby ensuring the repeatability accuracy of subsequent automated operations (such as robot gripping, vision positioning, and processing head docking).

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
