The mounting plate is provided with a avoidance hole, and the transverse screw module is installed on the mounting plate. The translation plate is mounted on the avoidance hole and is drivingly connected to the transverse screw module, and moves laterally on the avoidance hole under the drive of the transverse screw module. The needle pressing cylinder is mounted on the translation plate and its piston rod is arranged to pass through the avoidance hole. The vacuum suction plate is connected to the piston rod of the needle pressing cylinder for sucking the blood collection needle and pressing the sucked blood collection needle into the blood collection needle mold under the drive of the needle pressing cylinder.

[0005] Optionally, at least one needle adsorption block strip is provided on the bottom surface of the vacuum suction plate, and the needle adsorption block strip has a plurality of vacuum suction holes arranged side by side and at intervals.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0026] In one embodiment of the present invention, Figures 1 to 4 As shown, an automated vacuum adsorption and conveying device for blood collection needles is provided, comprising a mounting plate 10, a translation plate 20, a vacuum suction plate 30, a needle pressing cylinder 40 and a transverse screw module 50. The mounting plate 10 is provided with a avoidance hole 11, and the transverse screw module 50 is installed on the mounting plate 10. The translation plate 20 is mounted on the avoidance hole 11 and is drivingly connected to the transverse screw module 50, and moves laterally on the avoidance hole 11 under the drive of the transverse screw module 50. The needle pressing cylinder 40 is mounted on the translation plate 20 and its piston rod is arranged to pass through the avoidance hole 11. The vacuum suction plate 30 is connected to the piston rod of the needle pressing cylinder 40 for sucking the blood collection needle and pressing the sucked blood collection needle into the blood collection needle mold under the drive of the needle pressing cylinder 40.

[0027] When the automatic vacuum adsorption and conveying device for blood collection needles provided by the embodiment of the utility model is working, the transverse screw module 50 controls the translation plate 20 connected to it to move horizontally to a set position. Since the needle pressing cylinder 40 is installed on the translation plate 20, the needle pressing cylinder 40 can control the vacuum suction plate 30 connected to it to move down to a suitable position to adsorb the blood collection needle. After that, the needle pressing cylinder 40 controls the vacuum suction plate 30 to rise again. Subsequently, the transverse screw module 50 controls the movable plate to move horizontally to another set position (i.e., above the blood collection needle mold). The pressing cylinder controls the vacuum suction plate 30 adsorbed with the blood collection needle to be pressed into the blood collection needle mold until the blood collection needle is placed in the mold cavity of the blood collection needle mold, completing the automatic vacuum adsorption and conveying work of the blood collection needle. The automatic vacuum adsorption and conveying device for blood collection needles of the utility model is suitable for point-to-point delivery of large quantities of blood collection needles, replacing manual operations, with a high degree of automation and high production efficiency.

[0028] It should be noted that the automated vacuum adsorption and transportation device for blood collection needles in this embodiment needs to be externally connected to a vacuum generator when it is used. The vacuum generator is a prior art and can be directly connected externally.

[0029] In one embodiment of the present invention, Figures 3-4As shown, at least one needle adsorption block strip 31 is provided on the bottom surface of the vacuum suction plate 30, and the needle adsorption block strip 31 has a plurality of vacuum suction holes 311 arranged side by side and at intervals. Specifically, the arrangement of the needle adsorption block strip 31 can be adapted to the shape of the cavity of the blood collection needle mold, and by arranging a plurality of vacuum suction holes 311 arranged side by side and at intervals on the needle adsorption block strip 31, it is possible to achieve single adsorption of multiple blood collection needles, and to achieve the loading of multiple blood collection needles at one time, so as to meet the requirements of batch transportation and batch production.

[0030] In one embodiment of the present invention, Figures 1 to 4 As shown, the corner of the vacuum suction plate 30 is also provided with a positioning column 32 for mating with the blood collection needle mold. Specifically, the positioning column 32 is provided to cooperate with the positioning hole provided in the blood collection needle mold, so as to ensure that the blood collection needle placed by adsorption can be accurately placed in the blood collection needle mold, and the subsequent injection molding product has a higher quality.

[0031] In one embodiment of the present invention, Figures 1-2 As shown in FIG. 4 , a shaft sleeve 21 is provided on the translation plate 20, and a guide shaft 22 is slidably connected to the shaft sleeve 21, and the lower end of the guide shaft 22 is connected and fixed to the vacuum suction plate 30. Specifically, the sliding guide cooperation between the guide shaft 22 and the shaft sleeve 21 can ensure that the upward and downward movement position of the vacuum suction plate 30 controlled by the pressure needle cylinder 40 is accurate and does not deviate.

[0032] In one embodiment of the present invention, Figures 1-2As shown, the transverse screw module 50 includes a motor 51, a screw 52, ​​a nut 53, three guide rails 54 and three sliders 55, wherein two of the guide rails 54 are arranged in parallel on both sides of the avoidance hole 11 and are fixedly connected to the mounting plate 10, another guide rail 54 and the screw 52 are arranged in parallel beside one of the guide rails 54, and the screw 52 is rotatably mounted on the mounting plate 10, one end of the screw 52 is connected to the motor 51, the nut 53 is threadedly connected to the screw 52, ​​and the three sliders 55 are respectively slidably connected to the three guide rails 54, and the translation plate 20 is mounted and fixed on the sliders 55 of the two guide rails 54 on both sides of the avoidance hole 11, and the other slider 55 is connected and fixed between the nut 53 and the translation plate 20. Specifically, when the transverse screw module 50 is working, the motor 51 drives the screw 52 to rotate, so that the nut 53 moves axially along the screw 52. Because the nut 53 is connected to an adjacent slider 55, the slider 55 drives the translation plate 20 connected to it to move horizontally above the avoidance hole 11. Since two other slides are connected to the bottom of the translation plate 20, the three sliders 55 are guided along the sliding of the three guide rails 54, which can stably support the lateral movement of the translation plate 20, thereby driving the components such as the pressing cylinder and the vacuum suction plate 30 directly or indirectly installed on the translation plate 20 to move smoothly horizontally.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
