[0026] In an embodiment of the present utility model, as Figures 1-2 shown, a clamping device for the injection molded finished product of a blood collection needle row is provided, including a translation screw module 10, a support plate 20, a lifting cylinder 30 and two finger cylinders 40. The translation screw module 10 is installed on the support plate 20. The lifting cylinder 30 is connected to the translation screw module 10 through a bracket 50 and is driven by the translation screw module 10 to move along the arrangement direction of the support plate 20. The piston rod of the lifting cylinder 30 is arranged downward. The two finger cylinders 40 are connected to the piston rod of the lifting cylinder 30 through a cross plate 60, and the two finger cylinders 40 are respectively installed at both ends of the cross plate 60. The two finger cylinders 40 are used to respectively grab both ends of a blood collection needle row formed by a plurality of injection molded blood collection needles in a row in a mold.
[0027] During operation, the translation screw module 10 controls the lifting cylinder 30 connected thereto through the bracket 50 to translate along the arrangement direction of the support plate 20, so that the lifting cylinder 30 can be driven above the mold where material needs to be taken and from above the mold to the designated material discharging position. When the lifting cylinder 30 translates above the mold, the lifting cylinder 30 drives the two finger cylinders 40 connected thereto through the cross plate 60 to move downward into the mold. The fingers of the two finger cylinders 40 open and respectively clamp both ends of a blood collection needle row formed by a plurality of injection molded blood collection needles in a row in the mold. Then the lifting cylinder 30 controls the two finger cylinders 40 to rise. Then, the translation screw module 12 drives the lifting cylinder 30 to move the two finger cylinders 40 to the material discharging position again. Finally, the two finger cylinders 40 release the clamped blood collection needle row. The clamping device for the injection molded finished product of the blood collection needle row of the present utility model realizes clamping both ends of a blood collection needle row formed by a plurality of blood collection needles in a row for material taking, realizes automatic material taking, and the material taking of a blood collection needle row formed by a plurality of blood collection needles in a row can achieve a single - time increment compared with the method of manually clamping blood collection needles one by one, with extremely high production efficiency, and is suitable for the automated production of a large number of blood collection needles.
[0028] In an embodiment of the present utility model, as Figures 1-2As shown, a plastic part 41 for soft contact with the blood collection needle row is arranged on the inner side of the clamping jaw of the finger cylinder 40. Specifically, the plastic part 41 arranged on the inner side of the clamping jaw of the finger cylinder 40 can achieve flexible contact with the blood collection needle row to be clamped, that is, avoid damaging the plastic shell of the blood collection needle row and improve the production quality.
[0029] In an embodiment of the present invention, as Figure 2 shown, a T-shaped groove 411 for clamping the blood collection needle row is arranged on the inner side of the plastic part 41. The design of the T-shaped groove 411 can best adapt to clamping the blood collection needle row. Moreover, the inner groove section of the T-shaped groove 411 can avoid full contact between the plastic part 41 and the blood collection needle row, so as to prevent the blood collection needle row from being adhered to the plastic part 41 when the blood collection needle row is put down, thus ensuring the stability of the blanking.
[0030] In an embodiment of the present invention, the bracket 50 includes a vertical aluminum profile 51, a horizontal aluminum profile 52 and an angle plate 53. The vertical aluminum profile 51 is vertically connected to the output end of the translation lead screw module 10. The horizontal aluminum profile 52 is horizontally arranged and is fixedly connected to the vertical aluminum profile 51 through the angle plate 53. The lifting cylinder 30 is installed upside down at the extending end of the horizontal aluminum profile 52. Specifically, the design of the bracket 50 is mainly used to mount the lifting cylinder 30 at a relatively high position to control the finger cylinder 40 connected thereto to have sufficient working space. Among them, the vertical aluminum profile 51 can ensure the height, the horizontal aluminum profile 52 can ensure extension in a relatively far direction, and finally the two are locked and connected together through the angle plate 53. In this way, the installed finger cylinder 40 has sufficient working space, and thus it is convenient to extend above the mold to pick up the blood collection needle row in the mold. The design is ingenious and highly practical.
[0031] In an embodiment of the present invention, as Figures 1-2As shown in the figure, the translation screw module 10 includes a motor 11, a screw 12, a nut 13, a slider 14, a guide rail 15 and a moving seat 16. The screw 12 and the guide rail 15 are horizontally and parallelly arranged. The screw 12 is rotatably installed on the support plate 20. One end of the screw 12 is connected to the motor 11. The guide rail 15 is fixedly installed on the support plate 20. The nut 13 is threadedly connected to the screw 12. The slider 14 is slidably engaged with the guide rail 15. The moving seat 16 is fixedly connected to both the nut 13 and the slider 14. The bracket 50 is fixedly connected to the moving seat 16. Specifically, the working mode of the translation screw module 10 is as follows: The motor 11 controls the rotation of the screw, thereby driving the nut 13 to move along the axial direction of the screw. Further, the moving seat 16 is driven by the nut 13 to perform translation guided by the sliding of the slider 14 on the guide rail 15, so as to control the translation of the bracket 50 connected to the moving seat 16, and finally drive the translation of the lifting cylinder 30 and the finger cylinder 40.
[0032] In an embodiment of the present invention, as Figures 1-2 shown, a plurality of spaced-apart support plates 70 are further provided at the bottom of the support plate 20. Specifically, the arrangement of the support plates 70 can facilitate the installation of the entire device at a relatively high position, which is convenient for cooperating with adjacent other automated devices.
[0033] Preferably, three support plates 70 are provided.
[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
