Technical Field

[0001] This application relates to the field of immersion machine equipment technology, and in particular to a workpiece clamping device for an immersion machine. Background Technology

[0002] In the impregnation process of electronic components and other workpieces, the impregnation machine needs to position the workpiece using a clamping device to complete the impregnation process. Existing impregnation machine clamping devices mostly use fixed-size fixtures or single elastic structures, which have obvious limitations: fixed fixtures are only suitable for workpieces of specific specifications, and frequent adjustments or replacements of fixtures are required when changing workpieces, resulting in low processing efficiency; the clamping force stability of single elastic structures is insufficient, and workpieces are prone to displacement due to vibration during transportation, or loosening due to changes in the performance of elastic components under high-temperature drying conditions, thus affecting the impregnation quality.

[0015] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0016] like Figures 1 to 2 As shown, one embodiment provides a workpiece clamping device for an impregnation machine, including: a housing 100, an opening and closing mechanism 200, and a clamping mechanism 300.

[0017] The aforementioned workpiece clamping device for an impregnation machine is applied in the drying equipment of the impregnation machine. The housing 100 is equipped with a chain conveyor mechanism, and multiple clamping mechanisms 300 are arranged side-by-side on the chain conveyor mechanism. The housing 100 also has an opening. Each time workpieces are loaded, the chain conveyor mechanism drives a clamping mechanism 300 to align with the opening, and a robotic arm moves rows of workpieces through the opening into a clamping mechanism 300 until all clamping mechanisms 300 on the chain conveyor mechanism are filled with workpieces.

[0018] The following is a detailed description of the workpiece clamping device used in an impregnation machine.

[0019] like Figures 1 to 2 As shown, the opening and closing mechanism 200 includes a drive cylinder 210, a connecting plate 220, guide posts 230, and a pressing member 240. The drive cylinder 210 is fixed to the housing 100, the connecting plate 220 is fixed to the output end of the drive cylinder 210, multiple guide posts 230 are fixed to the connecting plate 220, and the guide posts 230 are movably inserted through the housing 100. The pressing member 240 is fixed to the guide posts 230 and located inside the housing 100. The clamping mechanism 300 includes a base 310, a float, and a buoyancy control system. The movable clamping plate 320 and the spring sheet assembly 330 are provided. The base 310 has an abutment wall and a bottom wall that are arranged opposite to each other, forming a cavity between the abutment wall and the bottom wall. The cavity has an inlet and an outlet that are arranged opposite to each other. There are two spring sheet assemblies 330, which are symmetrically arranged on the bottom wall. The floating clamping plate 320 is connected to the two spring sheet assemblies 330. The floating clamping plate 320 can move in the cavity. The floating clamping plate 320 has a protrusion that cooperates with the pressing member 240. The protrusion is located outside the cavity.

[0020] When a workpiece is loaded, the pressing component 240, driven by the drive cylinder 210, moves towards the protrusion and contacts it, causing the floating clamping plate 320 to move downward and compressing the spring sheet assembly 330. At this time, a space is formed between the floating clamping plate 320 and the abutment wall. The robot arm passes a row of workpieces through the feed port and places them in the space between the floating clamping plate 320 and the abutment wall. At this time, the pressing component 240 gradually moves upward, and the floating clamping plate 320 moves upward under the force of the spring sheet assembly 330, thereby providing an upward force on the workpiece and pressing it against the abutment wall to complete the fixation. In this way, this device, through the cooperation of the opening and closing mechanism 200 and the clamping mechanism 300, can adapt to workpieces of different sizes and avoid frequent adjustments or changes of clamps.

[0021] like Figures 1 to 2 As shown, in some embodiments, a through groove is provided on the abutment wall, and the through groove is arranged along the length direction of the base 310. The through groove can prevent the protruding part of the workpiece from interfering with the abutment wall, ensuring that the workpiece can smoothly fit the abutment wall and the bottom wall.

[0022] like Figures 1 to 2 As shown, in some embodiments, the width of the protrusion is greater than the distance between the two inner surfaces of the base 310.

[0023] Understandably, since the width of the protrusion is greater than the distance between the two inner sides of the base 310, the two ends of the protrusion are located at the side edges of the base 310, forming a limiting structure to prevent the protrusion from entering the cavity and to ensure that the pressing member 240 can always effectively contact the protrusion. In this way, the degree of freedom of the floating clamping plate 320 is restricted, preventing the floating clamping plate 320 from shifting along the length direction of the base 310.

[0024] like Figures 1 to 2 As shown, in some embodiments, the spring assembly 330 includes a first spring 331 and a second spring 332. The first spring 331 is fixed to the bottom wall, and the second spring 332 is fixed to the floating clamping plate 320. The first spring 331 and the second spring 332 are fixed by rivets.

[0025] The spring assembly 330 features a double spring design, resulting in greater elastic deformation and more stable recovery force. This allows it to better adapt to the clamping requirements of workpieces of different sizes, while also preventing workpiece damage caused by excessive rigidity of a single spring.

[0026] like Figures 1 to 2 As shown, in some embodiments, there are four guide posts 230, with two guide posts 230 forming a group, and the two groups of guide posts 230 are respectively located at both ends of the connecting plate 220.

[0027] like Figures 1 to 2 As shown, in some embodiments, the housing 100 is equipped with linear bearings, each corresponding to a guide post 230, with the guide post 230 passing through the linear bearing. In this way, the linear bearings ensure that the guide post 230 always moves along a preset axis, maintaining the movement accuracy of the guide post 230 and the pressing member 240 even after long-term use. This prevents pressing misalignment caused by wear of the guide post 230, ensuring the long-term reliability of the device.
