[0038] In the embodiment of the present application, the clamp can be connected to the equipment through the fixed plate 1, and the clamp is moved to the loading and unloading station by the equipment. The two driving parts 3 are respectively driven to slide the two picking arms 2 relative to or away from each other, so that the distance between the two picking arms 2 is expanded or reduced, thereby achieving the clamping or release of the gift box.

[0039] In the embodiment of the present application, since the installation position of the driving member 3 on the fixed plate 1 can be adjusted along the sliding direction of the material picking arm 2, and the material picking arm 2 forms a sliding connection with the fixed plate 1 through the sliding mechanism, the distance between the two material picking arms 2 can be adjusted within the maximum range. Therefore, the range of products that can be clamped is adjustable, and the versatility is strong. The same loading and unloading fixture can be used on different production equipment; the loading and unloading fixture has a simple structure and is easy to install. It can be installed on different equipment for use. There is no need to replace the fixture when changing the model of the production line. Only the fixture needs to be adjusted according to the product model, which is conducive to reducing the time for changing the model and avoiding the situation where there are many types of loading and unloading fixtures for the equipment, the production line has a long time for changing the model, and the model change is difficult.

[0040] According to some embodiments of the present application, the sliding mechanism includes a slide rail 4 and two sliders 5, the slide rail 4 is fixedly arranged on the fixed plate 1, the two sliders 5 are slidably arranged on the slide rail 4, and the two material-collecting arms 2 are respectively connected to the two sliders 5. Specifically, the slide rail 4 is located below the two driving members 3, and the slide rail 4 is connected to the fixed plate 1 by screws. The matching cross-sectional shape of the slide rail 4 and the slider 5 can be selected from existing forms, such as common triangles, rectangles, dovetails, circles, V-shapes, planes, etc., as long as a smooth linear sliding motion can be achieved, and no special limitation is made here.

[0041] According to some embodiments of the present application, a mounting plate 6 is provided on the slider 5, and the material picking arm 2 is connected to the mounting plate 6. Specifically, the mounting plate 6 is provided on the side of the slider 5 away from the fixed plate 1, and the mounting plate 6 can be connected to the slider 5 by screws, and the material picking arm 2 is detachably connected to the mounting plate 6 by screws, that is, the material picking arm 2 is indirectly connected to the slider 5 by the mounting plate 6, and the driving member 3 can drive the material picking arm 2 to slide smoothly along the slide rail 4 when the driving member 3 is actuated. It should be noted that, depending on the position of the slider 5 on the slide rail 4, when the slider 5 approaches the bottom of the driving member 3, the mounting plate 6 may block the front side of the driving member 3, so a waist-shaped notch 61 is provided on the mounting plate 6, so that the tool can be inserted through the waist-shaped notch 61 to adjust the fixing screws of the driving member 3.

[0042] According to some embodiments of the present application, the output end of the driving member 3 is provided with a connecting block 7, and the connecting block 7 is connected to the mounting plate 6. Specifically, one end of the connecting block 7 is connected to the output end of the driving member 3, and the other end is connected to the mounting plate 6 through a screw, and when the driving member 3 is actuated, the slider 5 is driven to reciprocate along the slide rail 4 through the connecting block 7 and the mounting plate 6. It should be noted that, since there may be a certain installation error between the driving member 3 and the slide rail 4, causing the motion axis of the output end of the driving member 3 to be not parallel to the guide direction of the slide rail 4, a waist-shaped hole 71 is provided on the connecting block 7 so that the connecting block 7 has a certain position adjustment capability.

[0043] According to some embodiments of the present application, the pick-up arm 2 and the connecting block 7 are respectively located at two ends of the mounting plate 6 along the extension direction of the slide rail 4, and the mounting positions of the pick-up arm 2 and the connecting block 7 on the mounting plate 6 can be interchanged. Specifically, screw holes are provided at both ends of the mounting plate 6, and the pick-up arm 2 and the connecting block 7 are fixedly connected to the mounting plate 6 by screws. When the size of the required fixture product is too small, the mounting position of the pick-up arm 2 can be transferred from the outside of the mounting plate 6 to the inside, that is, the pick-up arm 2 has two mounting methods, which can further expand the range of applicable products.

[0044] According to some embodiments of the present application, a reinforcing block 8 is provided on the mounting plate 6, and one end of the reinforcing block 8 is connected to the material picking arm 2. The reinforcing block 8 is connected to the mounting plate 6 by screws, and according to the installation position of the material picking arm 2, one end of the reinforcing block 8 can be abutted against or screwed to the material picking arm 2, so that a certain structural reinforcement effect can be played on the end of the material picking arm 2 connected to the mounting plate 6.

[0045] According to some embodiments of the present application, a fixing hole 11 is provided on the fixing plate 1, and the fixing hole 11 is a strip-shaped hole extending along the sliding direction of the material-grabbing arm 2, and the driving member 3 is installed on the fixing plate 1 through the fixing hole 11. Specifically, there are four fixing holes 11 and they are divided into two groups, and both groups of fixing holes 11 are located above the slide rail 4, and the two groups of fixing holes are arranged at the same height relative to the slide rail 4, and each driving member 3 is fixed through two fixing holes 11. When the driving member 3 is installed, its position can be adjusted along the fixing hole 11, that is, the installation position of the driving member 3 is not unique, and can be adjusted left and right according to the situation.

[0046] According to some embodiments of the present application, the shape of the pick-up arm 2 is adapted to the clamping surface of the workpiece to be clamped. In this embodiment, the pick-up arm 2 can be a plate-like structure, which is suitable for clamping all flat products. Of course, the shape of the pick-up arm 2 can be designed according to the clamping surface of the product, thereby expanding the range of products that can be clamped to circular, arc-shaped, etc. In order to reduce the weight of the pick-up arm 2, a plurality of weight-reducing holes can be opened on the pick-up arm 2.

[0047] According to some embodiments of the present application, the driving member 3 is a cylinder or a hydraulic cylinder. Specifically, the extended end of the piston rod of the cylinder or the hydraulic cylinder is connected to the connecting block 7. In order to achieve rapid clamping and loosening of the gift box, the cylinder or the hydraulic cylinder can be a double-acting cylinder or hydraulic cylinder. Of course, the driving member 3 is not limited to the above two types, as long as it can output linear reciprocating motion, for example, the driving member 3 can also be an electric linear push rod.

[0048] The universal loading and unloading fixture in the embodiment of the present application is installed on the equipment through a fixing plate. The equipment drives the fixture to move to the material picking position. After it is in place, the cylinder extends so that the opening formed between the two picking arms is larger than the product size. When the fixture receives a signal that the product is in place, the cylinder retracts and drives the picking arm to clamp the product. The equipment then drives the fixture to the discharge position. After it is in place, the cylinder extends and the fixture completes the discharge action. When the product to be clamped is particularly narrow, the installation position of the picking arm can be adjusted to the inside of the mounting plate. This installation method is suitable for products with particularly narrow dimensions.
