Description

Technical Field

[0001] This invention relates to the field of automated medical production equipment, and more specifically, to an automated needle handle assembly method and assembly equipment. Background Technology

[0002] Intravenous needles are widely used in clinical practice. There are generally two types of needle hubs: single-leaf and double-leaf. The double-leaf needle hub consists of a tubular handle and two blades connected to the outer wall of the handle. One end of the handle is connected to a catheter, and the other end is connected to a steel needle. During use or operation, the double-leaf needle hub offers advantages such as safer operation and less contamination.

[0003] However, the assembly of the needle handle of existing double-leaf needles is generally done manually. Since the components or parts of the needle handle are small and have many grooves, and the needle body is easy to prick hands when assembled manually, the assembly is difficult, unsafe and has a high error rate, resulting in low production efficiency of double-leaf needles. Summary of the Invention

[0004] The objectives of this invention include, for example, providing an automated needle handle assembly method and an automated needle handle assembly device, which can effectively reduce the assembly difficulty and error rate of the needle handle of a double-leaf needle, improve the assembly efficiency and safety of the needle handle, thereby improving the production efficiency of the double-leaf needle.

[0005] The embodiments of the present invention can be implemented as follows:

[0006] In a first aspect, the present invention provides an automated needle handle assembly method, comprising:

[0007] S10: Needle holder feeding: The needle holder feeding device places the needle holder onto the conveying device;

[0008] S20: Slider assembly: During the slider feeding process, the conveying device drives the needle seat to the slider assembly station, and the slider assembly device puts the slider onto the needle seat;

[0009] S30: Spring assembly: During the spring feeding process, the conveying device drives the needle seat and the slider to the spring assembly station, and the spring assembly device puts the spring on the needle seat and supports it on the slider.

[0010] S40: Top cover assembly: During the top cover feeding process, the conveying device drives the needle seat, the slider and the spring to the top cover assembly station. The top cover assembly device puts the top cover on the needle seat and compresses the spring together with the slider to form a semi-finished component.

[0011] S50: Side cover assembly: During the side cover feeding process, the conveyor device drives the semi-finished components to the side cover assembly station, and the side cover assembly device snaps the side cover onto the upper cover.

[0012] S60: Double blade assembly: During the double blade feeding process, the conveying device drives the semi-finished component and the side cover to the double blade assembly station. The double blade assembly device puts the double blades on the upper cover to form a needle handle.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: This automated needle holder assembly method sequentially uses a needle holder feeding device to feed the needle holder, a slider assembly device to assemble the slider, a spring assembly device to assemble the spring, a top cover assembly device to assemble the top cover, a side cover assembly device to assemble the side cover, and a double-blade assembly device to assemble the double blades, thereby completing the automated assembly of the needle holder. Compared with the manual or semi-automatic assembly in existing technologies, this method can effectively reduce the assembly difficulty and error rate of the double-blade needle holder, improve the assembly efficiency of the needle holder, and thus improve the production efficiency of the double-blade needle.

[0014] In an optional implementation, step S20 specifically includes:

[0015] S21: The slider feeding device transports the slider to the slider positioning base;

[0016] S22: The slider feed sensor detects whether the slider has reached the slider positioning base;

[0017] S23: When the slider reaches the slider positioning base, the slider limiting mechanism restricts the slider from continuing to be conveyed;

[0018] S24: Adjust the placement direction of the slider so that the slider is placed upright;

[0019] S25: The slider clamping mechanism is used to transfer the upright slider to the slider transfer base and from the slider transfer base to the slider fixing assembly mechanism;

[0020] S26: The slider fixing assembly mechanism fixes the slider and snaps it into the needle seat.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: By using a slider limiting mechanism to restrict the continued transport of sliders when they reach the slider positioning base, the sliders can be assembled in an orderly manner, preventing subsequently transported sliders from affecting the sliders on the positioning base. By adjusting the placement direction of the sliders, it can be ensured that the sliders are assembled on the needle holder in the correct posture, thus guaranteeing the accuracy of slider assembly.

[0024] S242: The slider orientation detection mechanism detects whether the slider transferred to the slider rotating base is placed in the correct orientation;

[0025] S243: The slider rotating base rotates to make the slider face up when the slider is placed in the reverse position.

[0026] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the slider placement direction is detected by the slider forward and reverse detection mechanism, and the slider placement direction is adjusted by rotating the slider base, which can accurately and conveniently achieve the adjustment of the slider placement direction.

[0027] In an optional implementation, step S242 specifically includes:

[0028] S242a: The negative pressure component adsorbs the slider through the air pores;

[0029] S242b: The sensing component detects the gas pressure or gas flow rate at the vent.

[0030] S242c: When the gas pressure or gas flow rate is less than or greater than the first threshold, it is determined that the slider is placed in reverse.

[0031] Compared with existing technologies, the technical effect achieved by this solution is that by using negative pressure to adsorb the slider and detecting the air pressure, the structural characteristics of different parts of the slider with different shapes can be cleverly utilized to accurately and conveniently determine the placement direction of the slider.

[0032] In an optional implementation, step S26 is followed by:

[0033] S27: The suction block adsorbs the slider;

[0034] S28: The suction block drives the slider to slide back and forth on the needle seat;

[0035] S29: Determine whether the slider slides smoothly. If the slider is found to slide smoothly, then proceed to step S30.

[0036] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: by inhaling air and holding the block to adsorb the slider and driving the slider to slide back and forth, the smoothness of the slider's sliding can be accurately and conveniently judged by detecting the magnitude of the adsorption force.

[0037] In an optional implementation, step S50 specifically includes:

[0038] S51: The side cover feeding device conveys the side cover to the side cover positioning base;

[0039] S52: The side cover feeding sensor detects whether the side cover has reached the side cover positioning base;

[0040] S53: When the side cover reaches the side cover positioning base, the side cover limiting mechanism restricts the side cover from continuing to be conveyed;

[0041] S54: Adjust the placement direction of the side cover so that the side cover is placed upright;

[0042] S55: The side cover clamping mechanism snaps the upright side cover into the top cover.

[0043] Compared with existing technologies, the technical effects achieved by this solution are as follows: By using a side cover limiting mechanism to restrict the continued transport of side covers when they reach the side cover positioning base, the side covers can be assembled in an orderly manner, preventing subsequently transported side covers from affecting the side covers on the positioning base. By adjusting the placement direction of the side covers, it can be ensured that the side covers can be assembled into the semi-finished components in the correct posture, thus ensuring the accuracy of side cover assembly.

[0044] In an optional implementation, step S54 specifically includes:

[0045] S541: The side cover clamping mechanism transfers the side cover from the side cover positioning base to the side cover rotating base;

[0046] S542: The side cover orientation detection mechanism detects whether the side cover on the side cover rotating base is placed in the correct orientation;

[0047] S543: The side cover rotating base rotates to make the side cover face up when the side cover is placed in the reverse position.

[0048] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the side cover orientation is detected by the side cover front and back detection mechanism, and the side cover orientation is adjusted by rotating the side cover rotating base, which can accurately and conveniently achieve the adjustment of the side cover orientation.

[0049] In an optional implementation, step S542 specifically includes:

[0050] S542a: The side cover front and back detection mechanism uses a CCD to acquire images of the side cover on the rotating base of the side cover;

[0051] S542b: Compare the image of the side cover with the pre-stored image;

[0052] S543c: When the similarity between the two is greater than or less than the second threshold, it is determined that the side cover is placed in reverse.

[0053] Compared with existing technologies, the technical effect achieved by this solution is that the placement direction of the side cover can be accurately and conveniently determined through CCD image detection and recognition.

[0054] In a second aspect, the present invention provides an automated needle handle assembly apparatus for use in the above-described automated needle handle assembly method, comprising:

[0055] The machine body is equipped with a conveyor device on top;

[0056] The needle seat feeding device, slider assembly device, spring assembly device, top cover assembly device, side cover assembly device, and double blade assembly device are sequentially arranged on the top of the machine body along the conveying direction of the conveying device.

[0057] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: This automated needle holder assembly equipment sequentially achieves needle holder feeding through a needle holder feeding device, slider assembly through a slider assembly device, spring assembly through a spring assembly device, top cover assembly through a top cover assembly device, side cover assembly through a side cover assembly device, and double blade assembly through a double blade assembly device, thereby completing the automated assembly of the needle holder. Compared with the manual or semi-automatic assembly in existing technologies, it can effectively reduce the assembly difficulty and error rate of double-blade needle holders, improve the assembly efficiency of needle holders, and thus improve the production efficiency of double-blade needles.

[0058] In an optional embodiment, the conveying device includes: a first turntable and a second turntable spaced apart on the top of the machine body, wherein the rotation direction of the first turntable is opposite to the rotation direction of the second turntable;

[0059] The needle seat feeding device, the slider assembly device, the spring assembly device, and the upper cover assembly device are arranged sequentially along the rotation direction of the first turntable. The side cover assembly device and the double blade assembly device are arranged sequentially along the rotation direction of the second turntable. A semi-finished product transfer device is provided between the first turntable and the second turntable. The semi-finished product transfer device is used to transfer semi-finished product components from the first turntable to the second turntable.

[0060] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by using two turntables rotating in opposite directions to transport the relevant parts of the needle handle to be assembled, multiple assembly devices can be arranged in a reasonable manner, reducing the length of the equipment, improving the compactness of the equipment structure, increasing the transport efficiency of the relevant parts, and ensuring the assembly efficiency of the equipment.

[0061] In an optional embodiment, the semi-finished product transfer device includes a semi-finished product clamping mechanism and a semi-finished product pitch-changing mechanism. The semi-finished product clamping mechanism is used to transfer semi-finished product components on the first turntable to the second turntable, and the semi-finished product pitch-changing mechanism is used to adjust the spacing between multiple semi-finished product components during the transfer process so that multiple semi-finished product components can be placed on the second turntable.

[0062] Compared with existing technologies, the technical effect achieved by this solution is as follows: The semi-finished product transfer device allows for adjustment of the spacing between multiple semi-finished components during transfer, thus adapting them to the second turntable. Because the distance between the semi-finished components differs between the first and second turntables, a semi-finished product pitch-adjusting mechanism is needed to adjust the spacing during the transfer from the first to the second turntable, ensuring that the multiple semi-finished components can be placed on the second turntable.

[0063] In an optional embodiment, the slider assembly device includes a slider positioning base, a slider feeding sensor, a slider limiting mechanism, a slider clamping mechanism, a slider rotating base, a slider forward / reverse detection mechanism, a slider transfer base, and a slider fixing assembly mechanism.

The slider clamping mechanism is used to transfer the slider on the slider positioning base to the slider rotating base. The slider forward / reverse detection mechanism is used to detect whether the slider transferred to the slider rotating base is placed in the correct orientation. The slider rotating base is used to rotate to make the slider in the correct orientation when the slider is placed in the reverse orientation. The slider clamping mechanism is used to transfer the in the correct orientation slider to the slider transfer base and from the slider transfer base to the slider fixing assembly mechanism. The slider fixing assembly mechanism is used to fix the slider and snap the slider into the needle seat.

[0064] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the slider assembly device can achieve efficient and accurate assembly of the slider, thereby improving the efficiency and accuracy of the entire needle holder assembly.

[0065] In an optional embodiment, the side cover assembly device includes a side cover feeding sensor, a side cover limiting mechanism, a side cover positioning base, a side cover clamping mechanism, a side cover orientation detection mechanism, and a side cover rotating base.

The side cover feeding sensor is used to detect whether the side cover has reached the side cover positioning base. The side cover limiting mechanism is used to restrict the side cover from continuing to be conveyed when the side cover reaches the side cover positioning base. The side cover clamping mechanism is used to transfer the side cover on the side cover positioning base to the side cover rotating base. The side cover orientation detection mechanism is used to detect whether the side cover on the side cover rotating base is placed in the correct orientation. The side cover rotating base is used to rotate to make the side cover in the correct orientation when the side cover is placed in the wrong orientation. The side cover clamping mechanism is used to clamp the side cover placed in the correct orientation onto the top cover.

[0066] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: the side cover assembly device can achieve efficient and accurate assembly of the side cover, thereby improving the efficiency and accuracy of the entire needle handle assembly.

[0067] In an optional embodiment, a needle holder detection device is provided between the needle holder feeding device and the slider assembly device for detecting whether the needle holder has been successfully fed.

[0068] A slider detection device is provided between the slider assembly device and the spring assembly device to detect whether the slider has been successfully assembled.

[0099] [First Embodiment]

[0100] Please refer to Figure 1 The first embodiment of the present invention provides an automated needle handle assembly method for assembling needle handles 900. Please refer to... Figure 2-4 The needle holder 900 includes a needle base 910, a slider 920, a spring 930, an upper cover 940, a lower cover, and a double blade 960. The slider 920 is sleeved on the needle base 910 and can slide back and forth along the length of the needle base 910. The spring 930 is sleeved on the needle base 910 and supported by the slider 920. The upper cover 940 is sleeved on the needle base 910 and compresses the spring 930 together with the slider 920. The lower cover is snapped into the upper cover 940. The double blade 960 is sleeved on the upper cover 940.

[0101] Please refer to again Figure 1 The automated assembly method for the needle handle includes the following steps:

[0102] S10: Needle holder 910 feeding: The needle holder 910 is fed in, and the needle holder feeding device 200 places the needle holder 910 on the conveying device;

[0103] S20: Slider 920 assembly: During the feeding process of slider 920, the conveying device drives needle holder 910 to slider 920 assembly station, and slider assembly device 300 puts slider 920 onto needle holder 910.

[0104] S30: Spring 930 Assembly: During the feeding process of spring 930, the conveying device drives the needle seat 910 and the slider 920 to the spring 930 assembly station. The spring assembly device 400 puts the spring 930 on the needle seat 910 and supports it on the slider 920.

[0105] S40: Assembly of upper cover 940: During the feeding process of upper cover 940, the conveying device drives the needle seat 910, slider 920 and spring 930 to the upper cover 940 assembly station. The upper cover assembly device 500 puts the upper cover 940 on the needle seat 910 and compresses the spring 930 together with the slider 920 to form a semi-finished component.

[0106] S50: Side cover 950 assembly: During the feeding process of side cover 950, the conveyor device drives the semi-finished component to the side cover 950 assembly station, and the side cover assembly device 700 snaps the side cover 950 onto the upper cover 940.

[0107] S60: Double blade 960 assembly: During the feeding process of double blade 960, the conveying device drives the semi-finished components and side cover 950 to the double blade 960 assembly station. The double blade assembly device 800 puts the double blade 960 onto the upper cover 940 to form the needle handle 900.

[0108] This automated needle holder assembly method sequentially feeds the needle holder 910 through the needle holder feeding device 200, assembles the slider 920 through the slider assembly device 300, assembles the spring 930 through the spring assembly device 400, assembles the upper cover 940 through the upper cover assembly device 500, assembles the side cover 950 through the side cover assembly device 700, and assembles the double blades 960 through the double blade assembly device 800, thereby completing the automated assembly of the needle holder 900. Compared with the manual or semi-automatic assembly in the prior art, it can effectively reduce the assembly difficulty and error rate of the needle holder 900 of the double-blade needle, improve the assembly efficiency of the needle holder 900, and thus improve the production efficiency of the double-blade needle.

[0109] Specifically, step S10 includes:

[0110] S11: The needle holder feeding device conveys the needle holder 910 to the needle holder positioning base;

[0111] S12: The needle holder feed sensor detects whether the needle holder 910 has reached the needle holder positioning base;

[0112] S13: When the needle holder 910 reaches the needle holder positioning base, the needle holder limiting mechanism restricts the needle holder 910 from continuing to be conveyed;

[0113] S14: The needle holder clamping mechanism transfers the needle holder 910 on the needle holder positioning base to the needle holder rotating base;

[0114] S15: The needle holder orientation detection mechanism detects whether the needle holder 910 on the rotating base of the needle holder is placed in the correct orientation;

[0115] S16: The needle holder rotating base rotates when the needle holder 910 is placed in the reverse position so that the needle holder 910 is placed in the upright position;

[0116] S17: The needle holder clamping mechanism transfers the upright needle holder 910 to the first turntable 110.

[0117] By using a needle holder limiting mechanism to restrict the continued conveying of needle holder 910 when it reaches the needle holder positioning base, the needle holder 910 can be transferred in an orderly manner, preventing subsequently conveyed needle holder 910 from affecting the needle holder 910 on the positioning base. By adjusting the placement direction of the needle holder 910, it can be ensured that the needle holder 910 is placed in the correct posture on the first turntable 110, thus ensuring the accuracy of needle holder 910 feeding.

[0118] Please refer to Figure 5 Step S20 specifically includes:

[0119] S21: The slider feeding device 320 conveys the slider 920 to the slider positioning base 301;

[0120] S22: The slider feed sensor detects whether slider 920 has reached slider positioning base 301;

[0121] S23: When the slider 920 reaches the slider positioning base 301, the slider limiting mechanism restricts the slider 920 from continuing to be conveyed;

[0122] S24: Adjust the placement direction of slider 920 so that slider 920 is placed upright;

[0123] S25: The slider clamping mechanism 303 is used to transfer the upright slider 920 to the slider transfer base and from the slider transfer base to the slider fixing assembly mechanism 305;

[0124] S26: The slider fixing assembly mechanism 305 fixes the slider 920 and snaps the slider 920 into the needle seat 910.

[0125] By using a slider limiting mechanism to restrict the continued transport of slider 920 when it reaches slider positioning base 301, the slider 920 can be assembled in an orderly manner, preventing subsequently transported sliders 920 from affecting the sliders 920 on slider positioning base 301. By adjusting the placement direction of slider 920, it can be ensured that slider 920 is assembled in the correct posture onto needle holder 910, guaranteeing the accuracy of slider 920 assembly.

[0126] Further, please refer to Figure 6 Step S24 specifically includes:

[0127] S241: The slider clamping mechanism 303 is used to transfer the slider 920 on the slider positioning base 301 to the slider rotating base 302;

[0128] S242: The slider orientation detection mechanism 304 detects whether the slider 920 transferred to the slider rotation base 302 is placed in the correct orientation;

[0129] S243: The slider rotating base 302 rotates to make the slider 920 face forward when the slider 920 is placed in the reverse position.

[0130] The placement direction of slider 920 is detected by slider forward / backward detection mechanism 304, and the placement direction of slider 920 is adjusted by rotating slider rotating base 302, so that the placement direction of slider 920 can be adjusted accurately and conveniently.

[0131] Furthermore, please refer to Figure 7 Step S242 specifically includes:

[0132] S242a: The negative pressure component adsorbs slider 920 through air holes;

[0133] S242b: The sensing component detects the gas pressure or gas flow rate at the vent.

[0134] S242c: When the gas pressure or gas flow rate is less than or greater than the first threshold, determine that slider 920 is placed in reverse.

[0135] By using a negative pressure adsorption slider 920 and detecting gas pressure, flow rate, and gas permeability, the structural characteristics of the different shapes of different parts of the slider 920 can be cleverly utilized to accurately and conveniently determine the placement direction of the slider 920. The different shapes of different parts of the slider 920 inevitably lead to different gas pressures or flow rates at the pores when adsorbing different parts. If the gas pressure or flow rate at the pores is at a first threshold when the slider 920 is placed upright, then the gas pressure or flow rate at the pores will necessarily be less than or greater than the first threshold when the slider 920 is placed in reverse. This allows determination of whether the slider 920 is placed in reverse.

[0136] Furthermore, please refer to Figure 5 Step S26 and the following steps include:

[0137] S27: Suction block adsorption slider 920;

[0138] S28: The suction block drives the slider 920 to slide back and forth on the needle holder 910;

[0139] S29: Determine whether slider 920 slides smoothly. If slider 920 is found to slide smoothly, then proceed to step S30.

[0140] By inhaling air and adsorbing the slider 920, the slider 920 is driven to slide back and forth. By detecting the magnitude of the adsorption force, the smoothness of the slider 920's sliding can be accurately and conveniently determined.

[0165] S543: The side cover rotating base rotates to make the side cover 950 face up when the side cover 950 is placed in the reverse position.

[0166] The placement direction of the side cover 950 is detected by the side cover front and back detection mechanism, and the placement direction of the side cover 950 is adjusted by rotating the side cover rotating base.

The slider 920 on the slider positioning base 301 is used to transfer the slider 920 to the slider rotating base 302. The slider orientation detection mechanism 304 is used to detect whether the slider 920 transferred to the slider rotating base 302 is placed in the correct orientation. The slider rotating base 302 is used to rotate so that the slider 920 is placed in the correct orientation when the slider 920 is placed in the reverse orientation. The slider clamping mechanism 303 is used to transfer the slider 920 placed in the correct orientation to the slider transfer base and from the slider transfer base to the slider fixing assembly mechanism 305. The slider fixing assembly mechanism 305 is used to fix the slider 920 and snap the slider 920 into the needle seat 910.

[0189] The slider assembly device 300 receives the slider 920 through the slider positioning base 301, adjusts the placement direction of the slider 920 through the slider clamping mechanism 303, the slider rotating base 302, and the slider forward and reverse detection mechanism 304, takes out the slider 920 placed in the forward position through the slider clamping mechanism, transfers it through the slider transfer base to the slider fixing assembly mechanism 305, and finally clamps the slider 920 onto the needle holder 910 through the slider fixing assembly mechanism 305.

The spring conveying mechanism is used to convey the spring 930 to the spring positioning base, and the spring clamping mechanism is used to sleeve the spring 930 on the spring positioning base onto the needle seat 910 and support it on the slider 920.

[0191] The spring assembly device 400 first transports the spring 930 to the spring positioning base through the spring conveying device, and then takes out the spring 930 from the spring positioning base through the spring clamping mechanism and puts it on the needle holder 910 and supports it on the slider 920. This can realize the efficient and accurate assembly of the spring 930, thereby improving the efficiency and accuracy of the assembly of the entire needle holder 900.

[0192] In detail, the cover assembly device 500 includes a cover conveying mechanism, a cover positioning base, a cover transfer base, a first cover clamping mechanism, and a second cover clamping mechanism. The cover conveying mechanism is used to convey the cover 940 to the cover positioning base. The first cover clamping mechanism is used to transfer the cover 940 from the cover positioning base to the cover transfer base. The cover transfer base is used to vertically position the cover 940. The second cover clamping mechanism is used to sleeve the vertical cover 940 onto the needle seat 910 and compress the spring 930 together with the slider 920 to form a semi-finished component.

[0193] The top cover assembly device 500 first transports the top cover 940 to the top cover positioning base through the top cover conveying mechanism. Then, the first top cover clamping mechanism transfers the top cover 940 on the top cover positioning base to the top cover transfer base for vertical positioning. Finally, the second top cover clamping mechanism fits the vertical top cover 940 onto the needle holder 910. This enables the efficient and accurate assembly of the top cover 940, thereby improving the efficiency and accuracy of the entire needle holder 900 assembly.

[0194] In detail, the semi-finished product transfer device 600 includes a semi-finished product clamping mechanism and a semi-finished product pitch changing mechanism. The semi-finished product clamping mechanism is used to transfer semi-finished product components on the first turntable 110 to the second turntable 120. The semi-finished product pitch changing mechanism is used to adjust the spacing between multiple semi-finished product components during the transfer process so that multiple semi-finished product components can be placed on the second turntable 120.

[0195] Furthermore, the semi-finished product transfer device 600 can adjust the spacing between multiple semi-finished product components during the transfer process, thereby adapting them to the second turntable 120. Because the distance between the multiple semi-finished product components is different on the first turntable 110 and the second turntable 120, the spacing needs to be adjusted by the semi-finished product pitch adjustment mechanism during the transfer from the first turntable 110 to the second turntable 120, so that the multiple semi-finished product components can be placed on the second turntable 120.

The side cover orientation detection mechanism is used to detect whether the side cover 950 on the side cover rotating base is placed in the correct orientation. The side cover rotating base is used to rotate to make the side cover 950 in the correct orientation when the side cover 950 is placed in the reverse orientation. The side cover clamping mechanism is used to snap the side cover 950 in the correct orientation onto the upper cover 940.

[0197] The side cover assembly device 700 first receives the side cover 950 through the side cover positioning base, then detects the side cover 950's orientation through the side cover clamping mechanism and the side cover positive / negative detection mechanism, and adjusts the side cover 950's placement orientation through the side cover rotating base. Finally, the side cover clamping mechanism takes the positively positioned side cover 950 out of the side cover rotating base and snaps it onto the upper cover 940. This enables the efficient and accurate assembly of the side cover 950, thereby improving the efficiency and accuracy of the entire needle handle 900 assembly.

[0198] In detail, the double blade assembly device 800 includes a double blade conveying mechanism, a double blade positioning base, and a double blade clamping mechanism. The double blade conveying mechanism is used to convey the double blade 960 to the double blade positioning base, and the double blade clamping mechanism is used to rotate the double blade 960 on the double blade positioning base and then fit it onto the upper cover 940 to form a needle handle 900.

[0199] The double-blade assembly device 800 first transports the double-blade 960 to the double-blade positioning base through the double-blade conveying mechanism, and then takes the double-blade 960 out of the double-blade positioning base through the double-blade clamping mechanism and rotates it to fit onto the upper cover 940. This enables the efficient and accurate assembly of the double-blade 960, thereby improving the efficiency and accuracy of the entire needle handle 900 assembly.

[0200] It should be noted that the feeding of the needle holder 910, slider 920, spring 930, top cover 940, side cover 950 and double blade 960 is all carried out by vibrating plate and linear slider, except for spring 930 which is conveyed by air blowing.
