Description

Technical Field

[0001] This technical solution relates to the field of blood collection needle assembly equipment technology, specifically a fixture for assembling blood collection needles. Background Technology

[0002] Blood collection needles are mainly used to quickly puncture the skin to collect blood for various medical tests such as blood glucose monitoring and routine blood tests, in order to understand the physiological and pathological conditions of the human body. They are widely used in the medical industry.

[0003] Existing blood collection needles typically consist of components such as a needle handle, catheter, flow stop clamp, needle seat, needle core, spring, and butterfly blade. Although the structure of a blood collection needle is small, it has many components. Manual or semi-automatic assembly is not only inefficient and costly, but also makes it difficult to ensure product consistency and quality stability. Therefore, it needs to be put into automated production. In order to increase output per unit time, it is necessary to assemble multiple sets of blood collection needles at the same time. Most fixture designs can only position, clamp, and assemble one or a few blood collection needle components at a time. There is a lack of fixtures that can arrange multiple processing stations at the same time. Utility Model Content

[0004] This technical solution aims to improve the problem of low production efficiency caused by the inability of existing blood collection needle fixtures to meet the needs of synchronous assembly at multiple workstations in the automated assembly of blood collection needles. It provides a fixture for assembling blood collection needles.

[0005] The purpose of this technical solution is achieved as follows: A fixture for assembling blood collection needles, comprising: Tooling strips; A clamping seat is provided on the tooling strip, and the clamping seat is provided with a plurality of clamping components for assembling blood collection needles; Two clamping plates are respectively installed on the tooling strips on both sides of the clamping seat. The top of each clamping plate is provided with several clamping grooves that match the clamping assembly for clamping and positioning of the conduit.

[0006] Through the above technical solution, when a fixture for assembling blood collection needles is in normal use, the fixture strip serves as a basic carrier to support the clamping seat, and multiple clamping components on the clamping seat synchronously clamp and fix the handle in the blood collection needle; at the same time, the clamping plates symmetrically installed on both sides of the fixture strip clamp and position the two ends of the catheter through the clamping groove, realizing multiple sets of parallel clamping, so that multiple sets of blood collection needle assemblies can simultaneously complete the positioning of key components (handles) on the same fixture, directly supporting the parallel operation of multi-station automated assembly lines, shortening the assembly cycle of a single piece, and improving the overall production efficiency.

[0007] Preferably, the top of the clamping base has a mounting groove corresponding to the clamping assembly, and the clamping assembly includes: A clamping block is hinged in the mounting groove, and a clamping groove is formed between the clamping block and the side wall of the mounting groove for the insertion of the blood collection needle handle; The elastic element has a receiving groove on the side wall of the mounting groove, and the elastic element is embedded in the receiving groove. The two ends of the elastic element abut against the bottom of the receiving groove and the clamping block, respectively. Its elastic force pushes the clamping block to rotate so as to achieve the positioning of the grip.

[0008] With the above technical solution, the blood collection needle handle is embedded in the clamping groove. The elastic element in the side wall of the clamping groove continuously applies elastic force to the clamping block, driving it to rotate and press against the handle to achieve self-locking. At the same time, the clamping plates symmetrically distributed on both sides of the tooling strip synchronously engage the catheter through the clamping groove at the top to achieve an elastic self-locking mechanism, making assembly convenient.

[0009] Preferably, the clamping block has a first guide slope, and the side wall of the clamping groove has a second guide slope. The inclined direction of the first guide slope and the second guide slope makes the opening of the clamping groove face outward and be flared.

[0010] With the above technical solution, when the handle slides in along the flared groove, the double-sloping structure automatically guides the handle to be accurately embedded, reducing the coefficient of friction. The flared structure provides guidance in the initial clamping stage and turns into a stable clamping force in the locking stage.

[0011] Preferably, a locking groove is recessed between the clamping block and the side wall of the mounting groove.

[0012] Through the above technical solution, the groove shape of the locking grooves on both sides matches the handle, improving the fit. The locking grooves on both sides work together to clamp the handle, further improving the installation stability of the handle and preventing it from accidentally coming off.

[0013] Preferably, the clamping seat is provided with two mounting plates, which are respectively fixed on opposite sides of the clamping seat. The mounting plates are provided with clearance for the grooves of the clamping slots, and the clamping blocks are hinged to the mounting plates on both sides by hinge shafts.

[0014] Through the above technical solution, the clamping block is hinged to the mounting plates on both sides by hinge shaft. The receiving slot can be quickly opened by removing the mounting plate, which facilitates the replacement of the clamping block and elastic element.

[0015] Preferably, a slider is installed at the bottom of the tooling strip for sliding cooperation with the slide rail.

[0016] Through the above technical solution, the tooling strip is set on the slide rail by sliding block, and multiple sets of fixtures are transported along the length of the slide rail to be installed step by step through each processing station.

[0017] Preferably, both the clamping base and the two clamping plates have process holes.

[0018] The above technical solution reduces the weight of the clamping seat and two clamping plates by using process holes, thereby reducing the conveying load and optimizing production efficiency.

[0019] Preferably, the opposite sidewalls of the clamping groove are provided with arc surfaces, and the arc surfaces on both sides cooperate to make the opening of the clamping groove flare outward.

[0020] With the above technical solution, the catheter slides into the clamping groove, the double arc surface structure automatically guides the catheter to be accurately embedded, reduces the friction coefficient, and the flared structure provides guidance during the clamping of the catheter.

[0021] The key and beneficial technical effects of this technical solution compared to existing technologies are: 1. This technical solution uses multiple clamping components on the clamping seat to simultaneously fix the blood collection needle handle, and cooperates with the tube clamping slots on both sides of the clamping plate to clamp the catheter, realizing multiple sets of parallel clamping. It can directly support the synchronous operation of multi-station automated assembly lines, thereby improving production efficiency.

[0022] 2. This technical solution uses an elastic element to drive the clamping block to automatically press the handle, forming a stable self-locking mechanism. At the same time, the clamping plates on both sides simultaneously fix the guide tube, achieving fast and precise clamping operations and further improving assembly efficiency.

[0025] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0026] Example: See Figure 1 and Figure 4A fixture for assembling blood collection needles includes a fixture strip 1, a clamping seat 2, and two clamping plates 3. The fixture strip 1 is long and plate-shaped. One or more sliders 12 are provided at the bottom of the fixture strip 1. The sliders 12 can be fixed to the conveying slide rail to realize the overall operation of the fixture. The fixture can be transported from the previous processing station to the next processing station along the conveying slide rail. The clamping seat 2 is centrally installed on the upper end face of the fixture strip 1. The two clamping plates 3 are located on opposite sides of the clamping seat 2 and are vertically fixed to the edge of the seat plate by bolts.

[0027] Both the clamping base 2 and the two clamping plates 3 have several process holes 13, which reduce the material to reduce weight, reduce the load on the conveyor, and improve the conveying efficiency.

[0028] See Figure 2 and Figure 3 The top of the clamping seat 2 has several mounting slots 6 along its length. Each mounting slot 6 has a clamping component 4 installed in it. The clamping component 4 adopts an elastic self-locking design: it includes a clamping block 41 and an elastic element 42. The clamping seat 2 has two mounting plates 10, which are bolted to the opposite sides of the clamping seat 2. The clamping block 41 is hinged to the mounting plates 10 on both sides through a hinge shaft 11. A clamping groove 7 is formed between the clamping block 41 and one side wall of the mounting slot 6, which is used for the grip 100 to be inserted. The mounting plates 10 have clearance at the slot openings of the clamping grooves 7.

[0029] The mounting groove 6 has a receiving groove 8 on one side wall, the shape and size of which match the elastic member 42. The elastic member 42 is installed in the corresponding receiving groove 8, and the two ends of the elastic member 42 abut against the bottom of the receiving groove 8 and the corresponding rear side wall of the clamping block 41, respectively.

[0030] The clamping block 41 has a locking groove 9 recessed between the side of the clamping block 41 away from the elastic element 42 and the corresponding side wall of the clamping groove 7. The groove is arc-shaped and fits the contour of the handle 100. The clamping block 41 has a guide slope 81, which is located at the opening of the clamping block 41 facing the clamping groove 7. The outer side of the side wall of the clamping groove 7 has a corresponding guide slope 82. The inclined direction of the two guide slopes makes the opening of the clamping groove 5 flare outward. During assembly, the handle 100... The handle 100 slides in along the guide slope 1 81 and guide slope 2 82, and correspondingly presses the clamping block 41 to rotate and avoid it. The handle 100 is embedded in the clamping groove 5 until it is locked in the locking grooves 9 on both sides. The elastic element 42 releases the elastic force to push the clamping block 41 to rotate. The clamping block 41 firmly locks the handle 100 in the locking groove 9, realizing the automatic centering and elastic clamping of the handle 100, and ensuring the stability of the workpiece during the conveying and assembly process.

[0031] Both clamping plates 3 have several clamping grooves 5 at their top ends, and each clamping groove 5 corresponds to a certain number of mounting grooves 6. These grooves are used to clamp and position the conduit 200. Each clamping groove 5 has an arc surface 14 on the opposite side wall of its opening. The arc surfaces 14 on both sides cooperate to make the opening of the clamping groove 5 flare outward. The conduit 200 is guided along the arc surfaces 14 on both sides and inserted into the groove of the conduit 200, so that both ends of the conduit 200 are clamped in the clamping grooves 5 on both sides, thus completing the material preparation.

[0032] The specific work process of this plan is as follows: This technical solution uses tooling strip 1 as a basic carrier to support clamping seat 2. Multiple clamping components 4 on clamping seat 2 synchronously clamp and fix the handle 100 in the blood collection needle. At the same time, clamping plates 3 symmetrically installed on both sides of tooling strip 1 are clamped and positioned at both ends of catheter 200 through clamping groove 5, realizing multiple sets of parallel clamping. This allows multiple sets of blood collection needle assemblies to complete the positioning of key components (handle 100) synchronously on the same fixture, directly supporting the parallel operation of multi-station automated assembly lines, shortening the assembly cycle of a single piece, and improving overall production efficiency.
