Detailed implementation mode

[0022] Next, the technical solutions in the new embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the new embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figure 1-6 , the present invention provides a technical solution: an electronic component pressing device, including a base 1, a threaded rod 2 is threadedly connected to the lower surface of the base 1, a support foot 3 is fixedly connected to the lower surface of the threaded rod 2, a universal wheel 4 is fixedly connected to the lower surface of the base 1, a workbench 5 is fixedly connected to the upper surface of the base 1, a control panel 6 is fixedly connected to one side surface of the workbench 5, a protection plate 7 is fixedly connected to the upper surface of the base 1, a positioning mechanism 8 is arranged on the upper surface of the workbench 5, and a pressing mechanism 9 is arranged on the upper surface of the workbench 5;

[0024] The pressing mechanism 9 includes a support rod 901, a limit plate 902, a limit groove 903, a cylinder 904, a moving block 905, a positive and negative lead screw 906, a motor 907, a connecting plate 908, a fixed rod 909, a spring 910, a mounting plate 911, a connecting column 912, a lower pressing plate 913, a pressing block 914 and a positioning column 915. The upper surface of the workbench 5 is fixedly connected with the support rod 901. The upper surface of the support rod 901 is fixedly connected with the limit plate 902. The inner surface of the limit plate 902 is provided with the limit groove 903. The inner surface of the limit groove 903 is slidably connected with the cylinder 904. One end surface of the cylinder 904 is fixedly connected with the moving block 905. The inner surface of the moving block 905 is threadedly connected with the positive and negative lead screw 906. One end surface of the positive and negative lead screw 906 is fixedly connected with the motor 907. One end surface of the cylinder 904 is fixedly connected with the connecting plate 908. The inner surface of the connecting plate 908 is slidably connected with the fixed rod 909. The lower surface of the connecting plate 908 is fixedly connected with the spring 910. One end surface of the fixed rod 909 is fixedly connected with the mounting plate 911. The lower surface of the mounting plate 911 is bolted with the connecting column 912. The lower surface of the connecting column 912 is fixedly connected with the lower pressing plate 913. The lower surface of the lower pressing plate 913 is fixedly connected with the pressing block 914. The lower surface of the lower pressing plate 913 is fixedly connected with the positioning column 915. Through the settings of the support rod 901, the limit plate 902, the limit groove 903, the cylinder 904, the moving block 905, the positive and negative lead screw 906, the motor 907, the connecting plate 908, the fixed rod 909, the spring 910, the mounting plate 911, the connecting column 912, the lower pressing plate 913, the pressing block 914 and the positioning column 915, when in use, first start the motor 907. When the motor 907 works, it drives the positive and negative lead screw 906 to rotate. The rotation of the positive and negative lead screw 906 will cause the moving block 905 to move linearly along the positive and negative lead screw 906, so as to realize the position adjustment of the pressing mechanism 9 in the horizontal direction, so as to accurately position the pressing block 914 above the electronic component to be pressed at a suitable position. The limit groove 903 inside the limit plate 902 guides the direction of the cylinder 904 and the moving block 905. Then, the cylinder 904 is started and extended. The cylinder 904 pushes the connecting plate 908 to move downward. The mounting plate 911 descends together with the connecting plate 908. The lower pressing plate 913 and the pressing block 914 are driven to move downward through the connecting column 912. The pressing block 914 contacts the positioned electronic component below and gradually applies pressure, realizing the pressing operation on the electronic component. When the pressing block 914 contacts the electronic component and starts to press, if the pressure is too large, the spring 910 can absorb part of the energy through its own elastic deformation.

[0025] Furthermore, multiple sets of support rods 901 are provided on the upper surface of the workbench 5, and two sets of moving blocks 905 are provided on the outer surface of the positive and negative lead screw 906. Through the setting of the support rods 901, during use, the multiple sets of support rods 901 disperse the force and jointly bear the weight of the limiting plate 902, making the limiting plate 902 more stable during the operation of the equipment.

[0026] Furthermore, the moving block 905 forms a sliding structure through the positive and negative lead screw 906 and the motor 907. Multiple sets of fixed rods 909 are provided on the inner surface of the connecting plate 908. Through the setting of the fixed rods 909, during use, the multiple sets of fixed rods 909 are evenly distributed on the inner surface of the connecting plate 908, providing a reliable vertical movement guide for the connecting plate 908 and the components connected below it, making the connecting plate 908 more stable during movement and preventing deviation and tilting.

[0027] Furthermore, one end surface of the spring 910 is fixedly connected to the mounting plate 911, and two sets of positioning columns 915 are provided on the lower surface of the lower pressing plate 913. Through the setting of the positioning columns 915, during use, the two sets of positioning columns 915 are simultaneously inserted into the positioning grooves 812, further reducing the possibility of horizontal displacement and deviation when the pressing block 914 presses down, improving the pressing accuracy.

[0028] Further, the positioning mechanism 8 includes an electric push rod 801, a sliding plate 802, a sliding block 803, a sliding groove 804, a slide rail 805, a limiting groove 806, a limiting rod 807, a first adjustment limiter 808, a stop block 809, a second adjustment limiter 810, a lower die plate 811 and a positioning groove 812. The upper surface of the workbench 5 is fixedly connected with an electric push rod 801. One end surface of the electric push rod 801 is fixedly connected with a sliding plate 802. The lower surface of the sliding plate 802 is fixedly connected with a sliding block 803. The lower surface of the sliding block 803 is provided with a sliding groove 804. The inner surface of the sliding groove 804 is slidably connected with a slide rail 805. One side surface of the sliding plate 802 is provided with a limiting groove 806. The upper surface of the workbench 5 is fixedly connected with a limiting rod 807. The upper surface of the workbench 5 is fixedly connected with a first adjustment limiter 808. One side surface of the sliding plate 802 is fixedly connected with a stop block 809. The upper surface of the workbench 5 is fixedly connected with a second adjustment limiter 810. The upper surface of the sliding plate 802 is fixedly connected with a lower die plate 811. The upper surface of the lower die plate 811 is provided with a positioning groove 812. Through the settings of the electric push rod 801, the sliding plate 802, the sliding block 803, the sliding groove 804, the slide rail 805, the limiting groove 806, the limiting rod 807, the first adjustment limiter 808, the stop block 809, the second adjustment limiter 810, the lower die plate 811 and the positioning groove 812, when in use, the electric push rod 801 is started to push the sliding plate 802 to move. Multiple groups of sliding blocks 803 at the bottom of the sliding plate 802 tightly hold the slide rail 805 through the matching sliding grooves 804 and slide smoothly. When the sliding plate 802 moves, two limiting rods 807 are inserted into the limiting groove 806 to restrict the displacement of the sliding plate 802. At the same time, the first adjustment limiter 808 limits the range of movement of the sliding plate 802 in one horizontal direction, and the stop block 809 and the second adjustment limiter 810 limit the range of movement of the sliding plate 802 in the other horizontal direction. The upper surface of the lower die plate 811 is provided with a component placement groove. When the pressing mechanism 9 presses down, the positioning post 915 will be inserted into the positioning groove 812.

[0029] Further, multiple groups of sliding blocks 803 are arranged at equal intervals on the lower surface of the sliding plate 802. The inner size of the sliding groove 804 matches the outer size of the slide rail 805. Through the settings of the sliding groove 804 and the slide rail 805, when in use, during the movement of the sliding plate 802, the sliding groove 804 of the sliding block 803 surrounds the slide rail 805, making the movement of the sliding plate 802 smoother and more stable.

[0030] Furthermore, multiple groups of slide rails 805 are equidistantly arranged on the upper surface of the workbench 5, and two groups of limiting rods 807 are equidistantly arranged on the upper surface of the workbench 5. With the arrangement of the slide rails 805, during use, the sliding plate 802 slides on the slide rails 805. When multiple groups of slide rails 805 are used simultaneously, the sliding plate 802 slides more stably without shaking or tilting.

[0031] Furthermore, the stopper 809 corresponds to the second adjustment limiter 810, and the inner dimension of the positioning groove 812 matches the outer dimension of the positioning post 915. Through this, the stopper 809 moves together with the sliding plate 802. When the stopper 809 touches the second adjustment limiter 810, it will stop moving, reducing the travel error of the sliding plate 802 and improving the accuracy of the positioning operation.

[0032] Working principle: Rotating the threaded rod 2 can flexibly adjust the height of the support feet 3, easily adapt to different ground flatness, and ensure the stability of the equipment. The universal wheels 4 facilitate the movement of the equipment. Place the electronic components into the component placement groove on the upper surface of the lower mold plate 811. Start the electric push rod 801 to push the sliding plate 802 to move. Multiple sliding blocks 803 at the bottom of the sliding plate 802 tightly fit into the sliding grooves 804 of the slide rails 805 and slide smoothly. When the sliding plate 802 moves, the two limiting rods 807 are inserted into the limiting grooves 806 to restrict the displacement of the sliding plate 802. At the same time, the first adjustment limiter 808 limits the movement range of the sliding plate 802 in one horizontal direction, and the stopper 809 and the second adjustment limiter 810 limit the movement range of the sliding plate 802 in the other horizontal direction. When the lower mold plate 811 moves to the appropriate position, start the motor 907. When the motor 907 works, it drives the forward and reverse lead screw 906 to rotate. The rotation of the forward and reverse lead screw 906 causes the moving block 905 to move linearly along the forward and reverse lead screw 906, thereby realizing the position adjustment of the pressing mechanism 9 in the horizontal direction to accurately position the pressing block 914 above the electronic component to be pressed. The limiting groove 903 inside the limiting plate 902 guides the direction of the cylinder 904 and the moving block 905. Then, the cylinder 904 is started and extended. The cylinder 904 pushes the connecting plate 908 downward. The mounting plate 911 descends together with the connecting plate 908, driving the lower pressing plate 913 and the pressing block 914 downward through the connecting column 912. The pressing block 914 contacts the positioned electronic component below and gradually applies pressure to realize the pressing operation of the electronic component. When the pressing block 914 contacts the electronic component and starts to press, if the pressure is too high, the spring 910 can absorb part of the energy through its own elastic deformation.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
