Through adopting above-mentioned technical scheme, the glue solidification required time is longer, if only set up first solidification equipment, then when the material in the past is solidifying through first solidification equipment, first transfer device need wait for the glue solidification and can't carry out follow-up material and transfer to influence production efficiency. And the glue is cured by the first curing device and the second curing device respectively, so that after the glue is pre-cured by the first curing device, the glue is transferred from the first transfer device to the second transfer device and then transferred to the second curing device by the second transfer device for further curing. And when the materials are transferred to the second curing device and cured by the second curing device, the first transfer device can simultaneously transfer the subsequent materials, thereby improving the production efficiency.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.
The embodiment of the invention firstly provides a production line of medical instruments as shown in fig. 1, which comprises a first transfer device 100, a pin inserting device 200, a heating device 300, a gluing device 400, a first curing device 500, a transplanting device 600, a second transfer device 700, a second curing device 800, a testing device 900 and a waste removing device 1000. The first transfer device 100 and the second transfer device 700 are located at opposite sides of the transplanting device 600. The transplanting device 600 is used to move the materials from the first transfer device 100 to the second transfer device 700.
Referring to fig. 1, 2 and 3, the first transfer device 100 includes a first driving member, a plurality of first grippers 110 and a plurality of auxiliary grippers 120. The plurality of first clamping members 110 rigidly clamp the material and the plurality of auxiliary clamping members 120 rigidly clamp the needle. Under the driving of the first driving member, the plurality of first clamping members 110 and the plurality of auxiliary clamping members 120 move circularly, so that the material clamped by the plurality of first clamping members 110 and the needles clamped by the plurality of auxiliary clamping members 120 are driven to move. Under the driving of the first driving member, the material moves to pass through the pin inserting device 200, the heating device 300, the glue coating device 400 and the first curing device 500 in sequence. Meanwhile, the moving direction of the material from the pin device 200 to the heating device 300 is opposite to the moving direction of the material from the heating device 300 to the gluing device 400 driven by the first driving member. The pin inserting device 200 is used for assembling pins and materials, the heating device 300 is used for heating the pin and material assembling parts, the glue coating device 400 is used for coating glue on the pin and material assembling parts, and the first curing device 500 is used for curing the glue through an ultraviolet lamp. When glue is coated to the needle and the material assembly part, the needle and the material assembly part are heated by the heating device 300, so that heat of the needle and the material assembly part can be transferred to the glue, the curing time of the glue of the needle and the material assembly part can be shortened, subsequent processing can be performed as soon as possible, and the production efficiency is improved. The material turns while passing through the heating device 300 on a path along which the first transfer device 100 transfers the material. Therefore, when the heating device 300 heats the material, the space is relatively large, and the pin inserting device 200 and the gluing device 400 are prevented from being heated while the material is heated.
Referring to fig. 2 and 4, the second transfer device 700 includes a second driving member and a plurality of second clamping members 710. Each of the second clamping members 710 includes a first clamping portion 711, a second clamping portion 712, a connecting portion 713, a body portion 714, and a stopper portion 715.
Referring to fig. 4, one end of the first clamping portion 711 and one end of the second clamping portion 712 are connected to two ends of the connecting portion 713, respectively, and the other end of the first clamping portion 711 remote from the connecting portion 713 and the other end of the second clamping portion 712 remote from the connecting portion 713 are spaced apart. The first clamping part 711 and the second clamping part 712 clamp the material. The first clamping part 711 and the second clamping part 712 can elastically maintain the relative positions of the first clamping part 711 and the second clamping part 712, so that the second clamping part 710 can elastically clamp the material. The body portion 714 surrounds the first clamping portion 711, the connecting portion 713, and the second clamping portion 712. The body portion 714 and the first clamping portion 711 are connected, the body portion 714 and the second clamping portion 712 are spaced apart, and the body portion 714 and the connecting portion 713 are also spaced apart. In the embodiment shown in fig. 1, the first clamping portion 711 is entirely connected to the body portion 714. The body portion 714 surrounds the first clamping portion 711 and the second clamping portion 712, so that the first clamping portion 711 and the second clamping portion 712 are protected, and the first clamping portion 711 and the second clamping portion 712 are prevented from being interfered and subjected to excessive elastic deformation, so that the performance of elastically maintaining the relative positions of the first clamping portion 711 and the second clamping portion 712 is affected. Compared to the manner in which the body portion 714 is connected to the first clamping portion 711 and the second clamping portion 712 at the same time, the body portion 714 is connected to the first clamping portion 711 and spaced apart from the second clamping portion 712, thereby reducing resistance to elastic deformation of the first clamping portion 711 and the second clamping portion 712. The main body 714 surrounds the connecting portion 713, thereby protecting the connecting portion 713 and preventing the connecting portion 713 from being interfered and being excessively elastically deformed, which affects the performance of the connecting portion 713 in elastically maintaining the relative positions of the first clamping portion 711 and the second clamping portion 712. The body portion 714 and the link portion 713 are spaced apart from each other, as compared to the manner in which the body portion 714 and the link portion 713 are connected, thereby reducing resistance to elastic deformation of the first and second clamping portions 711 and 712.
Referring to fig. 4, the first clamping parts 711, the second clamping parts 712, the connecting parts 713, and the limiting parts 715 correspond one-to-one, and the number of the first connecting parts 713, the second clamping parts 712, the connecting parts 713, and the limiting parts 715 is adapted to the main body part 714. In the embodiment shown in fig. 1, the number of the first clamping portion 711, the second clamping portion 712, the connecting portion 713 and the limiting portion 715 is 12. The 12 first clamping portions 711, the 12 second clamping portions 712, the 12 connecting portions 713, and the 12 stopper portions 715 are divided into two rows. The body portion 714 is connected to the first clamping portion 711 of the two rows and surrounds the first clamping portion 711, the connecting portion 713, and the second clamping portion 712 of the two rows. The body portion 714 is spaced apart from the second clamping portion 712 in the two rows, and the body portion 714 is spaced apart from the connecting portion 713 in the two rows.
Referring to fig. 4, the second clamping portion 712 includes a stopper section 712a and a clamping section 712 b. The two ends of the clamping section 712b are connected to the connection portion 713 and the limiting section 712a, respectively. The minimum distance between the stopper 712a and the first clamping part 711 is smaller than the distance between the clamping part 712b and the first clamping part 711. The end of the limiting section 712a remote from the clamping section 712b is provided with a guiding surface 712a1 guiding the material to enter between the clamping section 712b and the first clamping part 711. When the material is clamped between the clamping section 712b and the first clamping portion 711, the material is blocked by the limiting portion 715 when leaving between the first clamping portion 711 and the second clamping portion 712, so that the difficulty of the material in separating from the second clamping member 710 is increased, and the material is prevented from easily separating from the second clamping member 710. The arrangement of the limiting portion 715 improves the difficulty of the material to be separated from the second clamping member 710, and also improves the difficulty of the material to enter between the first clamping portion 711 and the second clamping portion 712. The provision of the guide surface 712a1 serves to guide the material into between the first clamp portion 711 and the second clamp portion 712.
Referring to fig. 4, one end of the stopper 715 is connected to the first clamping part 711, and the other end of the stopper 715 is spaced apart from the clamping segment 712 b. A first positioning space 716a and a second positioning space 716b are formed between the clamping section 712b and the first clamping part 711. The position-limiting portion 715 is located between the first positioning space 716a and the second positioning space 716 b. Since the other end of the stopper 715 is spaced apart from the holding section 712b, the first positioning space 716a and the second positioning space 716b are in a communicating state. The side of the limiting portion 715 facing the first positioning space 716a is smoothly connected to the first clamping portion 711, and the side of the limiting portion 715 facing the second positioning space 716b is smoothly connected to the first clamping portion 711. Assuming that the first positioning space 716a is closer to the limiting section 712a than the second positioning space 716b, the material is generally held in the first positioning space 716a, and the second positioning space 716b is in an empty state. However, during the process of clamping and releasing the material, the second positioning space 716b is changed along with the movement of the clamping section 712b relative to the first clamping part 711, thereby reducing the resistance of the elastic deformation of the first clamping part 711 and the second clamping part 712.
The first transfer device 100 needs to transfer the materials sequentially through the pin inserting device 200, the heating device 300 and the glue applying device 400. After the needle and the material are assembled by the needle inserting device 200, but the relative positions of the needle and the material are not fixed by glue, the relative positions of the needle and the material are not fixed, and therefore, the first transfer device 100 needs to clamp the needle and the material by the auxiliary clamp 120 and the first clamp 110 respectively during the transfer process to fix the relative positions of the needle and the material. The diameter of the needle is usually small, and if the auxiliary clamping member 120 adopts an elastic clamping manner, the needle cannot be effectively clamped by the auxiliary clamping member 120. When the material passes through the heating device 300 and the heating device 300 needs to heat the material, the first clamping member 110 and the auxiliary clamping member 120 are inevitably heated. If the first clamping member 110 and the auxiliary clamping member 120 are elastically clamped, the first clamping member 110 and the auxiliary clamping member 120 are usually made of plastic materials, and thus cannot bear the heat of the heating device 300. Therefore, the first clamping member 110 and the auxiliary clamping member 120 need to adopt a rigid manner for clamping the material. When the needles and the materials are on the second transfer device 700, the needles and the materials have already passed through the first curing device 500, so that the relative positions of the needles and the materials can be fixed by the glue to a certain degree, and at the moment, the second clamping piece 710 only clamps the materials, and the needles cannot move relative to the materials. Finally, the second transfer device does not need to be provided with the auxiliary gripper 120 gripping the needle, thereby reducing the cost. And second holder 710 adopts the mode of elasticity centre gripping material to make second holder 710 all need not to open the operation earlier when centre gripping material and unclamping the material, accelerate the material and transfer speed, improve production efficiency.
Referring to fig. 1 and 5, the second clamping members 710 are driven by the second driving member to move circularly, so as to drive the material clamped by the second clamping members 710 to move. Under the driving of the second driving member, the material moves to pass through the second curing device 800, the testing device 900 and the waste removing device 1000 in sequence. The second curing device 800 further cures the glue using a mercury lamp. The testing apparatus 900 is used to test whether the needle and the material after the glue is cured have a blockage or a leakage. Reject device 1000 comprises reject driving member 1100 and reject member 1200. The waste rejecting driving member 1100 drives the waste rejecting member 1200 to move to act on the material, and the material overcomes the resistance of the second clamping member 710 under the action of the waste rejecting member 1200 and is separated from the second clamping member 710, so that the waste rejecting efficiency is improved. The time required for glue curing is long, and if only the first curing device 500 is provided, when the previous material is cured by the first curing device 500, the first transfer device 100 needs to wait for glue curing and cannot transfer the subsequent material, thereby affecting the production efficiency. The glue is cured by the first curing device 500 and the second curing device 800, respectively, so that after the glue is pre-cured by the first curing device 500, the glue is transferred from the first transfer device 100 to the second transfer device 700, and then transferred to the second curing device 800 by the second transfer device 700 for further curing. While the material is transferred to the second curing device 800 and cured by the second curing device 800, the first transfer device 100 may simultaneously transfer the subsequent material, thereby improving the production efficiency. The uv lamp typically only causes the surface of the glue to cure while the interior of the glue is typically not yet cured. Mercury lamps can promote curing also inside the glue. Therefore, the ultraviolet lamp and the mercury lamp are matched to realize the solidification of the glue from inside to outside.
Referring to fig. 1 and 2, the transplanting apparatus 600 includes a transplanting driving member and a transplanting holding member 610. Transplanting gripper 610 rigidly grips the material. When the material is transplanted by the transplanting device 600, the transplanting driving member drives the transplanting holding members 610 to approach and hold the material, and at this time, the first holding members 110 are also in a state of holding the material, and the auxiliary holding members 120 are also in a state of holding the needles. Subsequently, first gripper 110 releases the material, auxiliary gripper 120 releases the needles, and the transplanting drive drives transplanting gripper 610 away from first gripper 110. Then, the transplanting driving member drives the transplanting gripper 610 to approach the second gripper 710 and release the material while the second gripper 710 grips the material. Finally, the transplanting driving member drives the transplanting clamps 610 to be reset for the next transfer. If the material is elastically clamped by the transplanting clamping member 610, the transplanting clamping member 610 and the second clamping member 710 both elastically clamp the material, thereby causing difficulty in transferring the material from the transplanting clamping member 610 to the second clamping member 710. Accordingly, the transplant grippers 610 need to rigidly grip the material so that the material can be transferred from the transplant grippers 610 to the second grippers 710.
