Description

Technical Field

[0001] This utility model relates to the field of hot pressing device technology, and in particular to a hot pressing slider suitable for a ring track. Background Technology

[0002] Hot pressing is a common joining or forming process widely used in electronics, plastics, textiles, and many other industries. In many automated production lines, continuous or batch hot pressing is required for workpieces transported along a specific path. Traditional automated hot pressing devices are typically designed for linear conveyor belts or workstations. The workflow of such devices is generally as follows: First, the hot pressing head descends to its designated position and applies hot pressure to the workpiece at the specific workstation; then, the hot pressing head and the workpiece (and the conveyor belt carrying the workpiece) move synchronously for a distance, maintaining the hot pressing state; after completing the predetermined hot pressing time or stroke, the hot pressing head rises and quickly returns to the starting point, awaiting the next workpiece or the next hot pressing cycle.

[0003] While this sequence of actions—"lowering the hot press, simultaneously moving synchronously with the conveyor belt, and lifting back"—is feasible on a straight path, it has significant limitations. First, it's a discontinuous, reciprocating process; each hot press requires stages of lowering, synchronous movement, and returning, which restricts the overall production line's speed and efficiency, especially in applications requiring high-speed continuous production. Second, this mode demands precise synchronization control, resulting in a relatively complex mechanism.

[0004] Applying the traditional linear reciprocating hot pressing device directly to a circular track presents significant challenges. The continuous motion characteristics of the circular track are incompatible with the discontinuous reciprocating motion mode of the traditional hot pressing device. More importantly, achieving automatic and precise pressing of the hot pressing head onto the workpiece during the continuous movement of the slider along the circular track, and automatic and rapid lifting after hot pressing, has become a core technical challenge. Existing solutions often require complex external cam mechanisms, pneumatic / hydraulic actuators in conjunction with sensors for position control, or completely stopping the slider's movement on the track to perform hot pressing. This not only increases the complexity, cost, and maintenance difficulty of the device but also fails to meet the demands of continuous and efficient production.

[0005] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hot-pressing slider that achieves automatic and efficient hot pressing on a circular track.

[0007] This utility model is achieved through the following technical solution:

[0008] To solve the above-mentioned technical problems, this utility model provides a hot-pressing slider suitable for a circular track, including a bracket, a roller assembly that cooperates with the circular track is rotatably connected to the bracket, a fixed plate is fixedly connected to the bracket, and a liftable upper movable plate is movably connected above the fixed plate. The upper surface of the upper movable plate can abut against the side of the circular track and can rise and fall with the shape of the side of the circular track. A first elastic reset member that elastically presses the upper movable plate upward is provided between the upper movable plate and the fixed plate. A lower movable plate located below the fixed plate is fixedly connected to the upper movable plate, and a hot-pressing device is provided on the lower movable plate.

[0009] To further solve the technical problems to be solved by this utility model, this utility model provides a hot-pressing slider suitable for a ring track. The hot-pressing device includes a hot-pressing plate that is movably connected to the lower movable plate and can be raised and lowered, and a heating element provided in the hot-pressing plate. A second elastic reset member is provided between the hot-pressing plate and the lower movable plate for elastically pressing the hot-pressing plate downward.

[0010] To further address the technical problems to be solved by this utility model, this utility model provides a hot-press slider suitable for an annular track, wherein the upper surface of the upper movable plate is rotatably connected with several top wheels that can abut against the side of the annular track.

[0011] To further address the technical problems to be solved by this utility model, this utility model provides a hot-pressing slider suitable for a circular track, wherein the bracket is provided with a carbon brush that can slide and abut against a conductive sheet laid on the circular track, and the carbon brush is electrically connected to the hot-pressing device.

[0012] To further address the technical problems to be solved by this utility model, this utility model provides a hot-press slider suitable for annular tracks, wherein the bracket has two parts, left and right, and clamps the periphery of the annular track between the two parts.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This invention provides a hot-pressing slider suitable for a circular track. Utilizing the specific vertical contour of the circular track's side as a mechanical linkage reference, and in conjunction with a first elastic reset component, it achieves automatic, externally driven vertical lifting and positioning of the hot-pressing device during continuous movement along the circular track. This design overcomes the difficulty of achieving continuous and efficient hot pressing on a circular track in existing technologies, significantly simplifying the structure and improving the speed and efficiency of hot pressing operations. Furthermore, by setting an independent second elastic reset component, it further ensures that the hot-pressing platen applies stable and reliable elastic hot-pressing pressure to the workpiece, improving process quality. Simultaneously, by adding additional structures such as top wheels or carbon brushes, friction can be further reduced, operational stability improved, and continuous power supply achieved during movement, thus providing a simpler, more efficient, and more stable circular track hot-pressing solution.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, wherein:

[0016] Figure 1 This is a three-dimensional structural schematic diagram of the present invention;

[0017] Figure 2 This is an exploded view of the present invention;

[0018] Figure 3 This is a cross-sectional view of the present invention;

[0019] Figure 4 This is a schematic diagram of the usage state of this utility model. Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1 to 4 As shown, this embodiment provides a hot-pressed slider suitable for a circular track. Its main structure includes a support 1. Preferably, in this embodiment, the support 1 is designed with two symmetrical parts, which can clamp the periphery of the circular track between them. This double-support structure not only increases the stability of the slider when moving on the track but also facilitates the installation of other components.

[0022] To enable the hot-pressed slider to move smoothly on the annular track, a roller assembly 2 is rotatably connected to the bracket 1 and cooperates with the annular track. The roller assembly 2 can be a combination of multiple rollers, for example, located at the bottom or side of the bracket 1, in contact with the surface or side of the annular track, supporting and guiding the slider to move along the track by rolling.

[0023] A fixing plate 3 is fixedly connected to the bracket 1, and its position is fixed relative to the bracket 1.

[0024] One of the core mechanisms of this invention is the realization of automatic lifting and lowering of the slider on the circular track. For this purpose, a movable upper plate 4 is movably connected above the fixed plate 3. Here, "movably connected" means that the upper movable plate 4 can move vertically (i.e., vertically) relative to the fixed plate 3 within a certain range (e.g., sliding connection along the vertical direction).

[0025] The key is that the upper surface of the upper movable plate 4 can abut against the side of the annular track. Furthermore, this upper movable plate 4 can automatically rise and fall according to the shape of the side of the annular track. This means that the side of the annular track not only serves a guiding function, but also has a specific vertical profile or height variation. As the slider moves circumferentially along the track, the upper surface of the upper movable plate 4 always conforms to or follows this vertical profile of the side of the annular track.

[0026] To ensure that the upper movable plate 4 always fits tightly against the side of the annular track, a first elastic reset member 5 is provided between the upper movable plate 4 and the fixed plate 3, which elastically presses the upper movable plate 4 upward. The first elastic reset member 5 can be, for example, a compression spring or an elastic body (such as elastic rubber). Its function is to provide a continuous upward force, pushing the upper surface of the upper movable plate 4 upward, so that it is pressed tightly against the side of the annular track. In this way, when there is a "descending" curve on the side of the annular track, the upper movable plate 4 will be forced to move downward by the side of the track; when there is an "ascending" curve on the side of the annular track, the elastic force of the first elastic reset member 5 will quickly push the upper movable plate 4 upward, so that it continues to rise following the contour of the side of the track. With this structure, the main body of the slider (including other components connected to the upper movable plate) can automatically achieve overall vertical lifting and lowering movement according to the preset shape of the side of the annular track.

[0027] A lower movable plate 6 is fixedly connected to the upper movable plate 4 and located below the fixed plate 3. Since the lower movable plate 6 is fixedly connected to the upper movable plate 4, the up-and-down movement of the upper movable plate 4 during the above process will synchronously drive the lower movable plate 6 to perform the same vertical displacement. Note that although the lower movable plate 6 is located below the fixed plate 3, it is not fixed to the fixed plate 3, but rather connected to the upper movable plate 4 through a connecting post passing through the fixed plate 3, thereby enabling movement relative to the fixed plate 3.

[0028] A hot pressing device 7 is provided on the lower movable plate 6. Since the hot pressing device 7 is mounted on the lower movable plate 6, its overall vertical position will automatically adjust as the lower movable plate 6 moves up and down. When the slider moves to the area with a lower profile on the side of the annular track, the hot pressing device 7 will descend to a working position close to or in contact with the workpiece; when the slider moves to the area with a higher profile on the side of the annular track, the hot pressing device 7 will rise away from the workpiece, achieving a non-working or return-to-position state.

[0029] like Figure 1-4 As shown, the hot pressing device 7 includes a hot pressing plate 71 that is movably connected (e.g., movably connected in the vertical direction) to the lower movable plate 6 and is liftable, and a heating element (not shown in detail in the figure, but a conventional heating component, such as a heating wire) disposed in the hot pressing plate 71. The hot pressing plate 71 is the working component that directly contacts the workpiece and applies heat and pressure. The heating element is responsible for converting electrical energy into heat energy to heat the hot pressing plate 71.

[0030] To achieve stable hot pressing pressure on the workpiece, a second elastic reset member 72 is provided between the hot pressing plate 71 and the lower movable plate 6 for elastically pressing the hot pressing plate 71 downwards. The second elastic reset member 72 can be, for example, a compression spring or an elastic pad. This second elastic member is key to achieving precise hot pressing. When the entire hot pressing device 7 descends to the working position with the lower movable plate 6, the hot pressing plate 71 will first contact the workpiece. At this time, the second elastic reset member 72 provides additional downward elastic force, pressing the hot pressing plate 71 firmly against the workpiece surface, applying the required hot pressing pressure, while allowing the hot pressing plate 71 to have a certain vertical floating space relative to the lower movable plate 6 to accommodate slight differences in workpiece height or surface, ensuring good contact and uniform pressure. This is a two-stage elastic working mechanism: the first stage of elasticity (the first elastic reset member 5) achieves coarse positioning and lifting of the entire hot pressing device by following the side profile of the track; the second stage of elasticity (the second elastic reset member 72) achieves precise positioning and elastic pressure of the hot pressing plate on the workpiece after the device descends to the correct position.

[0031] like Figure 1-4 As shown, in order to further reduce the frictional force when the upper movable plate 4 contacts the side of the annular track and improve the smoothness and reliability of the slider movement, in this embodiment, preferably, the upper surface of the upper movable plate 4 is rotatably connected with several top wheels 8 that can abut against the side of the annular track. These top wheels 8 can be, for example, rollers composed of ball bearings or roller bearings and an outer ring. They transform the sliding friction between the upper surface of the upper movable plate 4 and the side of the track into rolling friction, significantly reducing frictional resistance, allowing the upper movable plate 4 to rise and fall more smoothly and accurately following the contour changes of the track side, while also reducing component wear.

[0032] To provide a continuous and stable power supply for the hot pressing device 7 during the movement of the slider, the support 1 is equipped with carbon brushes 9 that can slide against conductive sheets (not shown in the figure, representing a conventional track power supply structure) laid on the annular track. The carbon brushes 9 are electrically connected to the hot pressing device 7 via wires. By laying conductive sheets in specific areas of the annular track (e.g., the area where hot pressing is required) and utilizing the sliding contact of the carbon brushes 9 during movement, an external power source (e.g., a low-voltage, high-current power supply) can be introduced to the moving hot pressing slider, ensuring the heating element functions properly.

[0033] The working principle of this embodiment is briefly described as follows:

[0034] The hot-pressing slider is supported on the circular track by the roller assembly 2 and moves continuously along the circumference of the track under the drive of the drive device (not shown in the figure, which may be a synchronous belt, chain, or linear motor, etc.). During the movement, the upper surface of the upper movable plate 4 is in close contact with the side profile of the circular track through the top wheel 8 (or in direct contact), and moves up and down following the height change of the track side under the upward pressing action of the first elastic reset member 5. Since the lower movable plate 6 and the hot-pressing device 7 are fixedly connected to the upper movable plate 4, they also move vertically in sync with the upper movable plate 4.

[0035] When the slider moves to the preset hot-pressing working area in the circular track, the track side profile of this area is designed to be at a lower height. At this time, the upper movable plate 4 is forced downward by the track side, causing the lower movable plate 6 and the hot-pressing device 7 to descend as a whole. When the hot-pressing plate 71 contacts the workpiece to be hot-pressed on the track, the second elastic reset member 72 located between the hot-pressing plate 71 and the lower movable plate 6 begins to be compressed, applying a downward elastic pressure to the hot-pressing plate 71. Simultaneously, electricity obtained from the track conductive sheet through the carbon brush 9 is supplied to the heating element in the hot-pressing device 7, heating the hot-pressing plate 71 to the preset temperature. Within the set hot-pressing area, the hot-pressing plate 71 continuously applies heat and pressure to the workpiece, completing the hot-pressing operation.

[0036] When the slider leaves the hot pressing working area and moves to the non-working area, the side profile of the track in this area is designed to be higher. At this time, the upper movable plate 4 moves upward along the track side, or is quickly pushed upward by the first elastic reset member 5, causing the lower movable plate 6 and the hot pressing device 7 to rise as a whole, so that the hot pressing plate 71 is separated from the workpiece, ending the hot pressing cycle. At the same time, the track in the non-working area may not have conductive plates, automatically cutting off the power supply to the hot pressing device 7.

[0037] The entire process requires no additional external drive or complex control system to independently control the lifting and lowering of the hot press head. The hot press device can automatically enter and exit the working state by relying solely on the interaction between the slider and the specific side profile of the ring track, and stable hot press pressurization can be achieved through the internal secondary elastic mechanism, which greatly simplifies the structure and improves efficiency.

[0038] This embodiment is merely one specific implementation of the present invention. Its structural parameters, material selection, type of elastic reset member, number and layout of roller groups and top rollers, and the specific shape of the side profile of the annular track can all be adjusted and optimized according to actual application requirements, but its basic principles and structural features remain unchanged. For example, the first elastic reset member 5 and the second elastic reset member 72 can be helical springs, leaf springs, rubber pads, or other elastic materials. The side profile of the annular track can be designed as a smooth curve or a transition section with a specific slope to achieve the required hot-pressing area and non-working area.
