[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] like Figures 1-4 As shown, a substrate clamping water-immersion fixture includes a main frame 1, on which a plurality of clamping cavities 5 for placing substrates 4 are provided, and adjacent clamping cavities 5 are separated by partitions 6.

[0029] Clamping assemblies 7 are installed on the main frame 1 on both the front and rear sides of the clamping cavity 5. Each clamping assembly 7 includes a clamping support block 71, an upper clamping plate 74, and a lower clamping connecting plate 76. The upper clamping plate 74 and the lower clamping connecting plate 76 are located on the upper and lower sides of the clamping support block 71, respectively, and the outer sides of the upper clamping plate 74 and the lower clamping connecting plate 76 are connected together, meaning they are integrally formed. Furthermore, the lower clamping connecting plate 76 is connected to the upper clamping support block 71 via several compression springs 75. These springs 75 are pre-compressed and clamped before the lower clamping connecting plate 76 connects to the upper clamping plate 74. The outer side of the upper clamping plate 74 is mounted in a rotating shaft mounting groove 72 on the main frame 1 via rotating shafts 73 distributed along the left-right direction. A pressure block 77 is installed on the inner bottom of the upper clamping plate 74.

[0030] A limiting upper boss 78 is arranged at the bottom of the clamping upper plate 74, and a limiting lower boss 79 matched with the limiting upper boss 78 is arranged on the clamping support block 71 below the limiting upper boss 78.

[0031] The clamping support block 71 is installed in a lower clamping installation cavity 9 opened below the main base frame 1, the clamping upper plate 74 is located in an upper clamping installation cavity 8 opened above the main base frame 1, and a step 10 is arranged on the main base frame 1 below the pressing block 77. When the substrate 4 is installed, the front and rear sides are placed on the step 10, and then the pressing block 77 above is clamped for processing.

[0032] A first bushing 2 is installed around the top of the main base frame 1. A plurality of second bushings 3 are installed on the outer side of the main base frame 1.

[0033] Except that the pressing block 77 needs to clamp the product using Teflon material, the rest of the parts use aluminum parts for oxidation treatment to avoid corrosion and rust to cause jamming problems.

[0034] When the substrate clamping water entry jig works, under the action of no external force, the substrate 4 is fixed on the main base frame 1 by the pressing spring 75 of the clamping assembly 7, and after entering the water, the substrate 4 is ensured not to shake on the main base frame 1. When the substrate 4 is fed or discharged, the lock pin needs to be unlocked to push the unlocking block (i.e. the clamping upper plate 74) to complete the rotary motion, so that the pressing block 77 is opened and retreated outside the limiting groove (i.e. the step 10) of the main base frame 1. The substrate 4 can be put in or taken out to complete the feeding or discharging.

[0035] The utility model discloses a product clamping through the mode of rotation shaft and pre-compression spring, all parts use aluminum and non-metal materials, effectively solve the problem of part rusting in water, and also can adapt to the working condition of high-temperature baking after water. Since the product needs to be detected except for the edge 5mm, and the detection head needs to be close to the product to complete the detection, the utility model can realize product clamping in a very small space, and the clamping is firm and not easy to cause product three injuries. At the same time, it can ensure the unlocking stability under the working conditions of underwater and high temperature.

[0036] In the description of the utility model, need understanding is, the term "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "internal", "external" and so on indicate the orientation or positional relation based on the orientation or positional relation shown in the drawing, just for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the indicated device or element must have a particular orientation, construct and operate in a particular orientation, therefore can not be understood as the limitation of the utility model. In addition, the term "first", "second" and so on are only for the purpose of description, and can not be understood as indicating or implying relative importance or implying the number of the indicated technical features. Therefore, the features limited by "first", "second" and so on can be explicitly or implicitly included one or more features. In the description of the utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0037] In the description of the utility model, it should be pointed out that, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected, can be mechanically connected, can be electrically connected, can be directly connected, can be indirectly connected through an intermediate medium, can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood through specific circumstances.

[0038] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, it should be pointed out that, for ordinary skilled in the art, on the premise of not departing from the technical principles of the utility model, can make several improvements and variations, these improvements and variations also should be regarded as the protection scope of the utility model.
