[0005] 2. Since it needs to be sent to the inside of the equipment, not only is it inconvenient to assemble due to the limited internal space, but also the breakage rate caused by collision is greatly increased, and the orientation of the needle punching needles also needs to be turned over, increasing the replacement difficulty. INVENTION CONTENTS

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a brand-new scissor type needle punching module replacement auxiliary device.

[0007] To solve the above technical problems, the utility model adopts the following technical scheme:

[0009] Preferably, the support frame is capable of being adjusted along the length direction of the slide rail to adjust the spacing between the support frames to meet the replacement and carrying of different width needle punching modules.

[0010] Further, the slide seat is provided with a butt joint hole extending along the length direction of the slide rail, and the support frame is assembled in position with the butt joint hole through the external connection part.

[0011] According to a specific implementation and preferred aspect of the present application, each support frame comprises a frame body and a shelf plate located at the top of the frame body, wherein the width of the shelf plate is less than the width of the frame body.

[0012] Preferably, the rear end of the shelf plate is aligned with the rear end of the frame body, and the front end of the shelf plate protrudes from the front end of the frame body and extends forward, wherein the length of the forward extension is less than the length of the frame body.

[0033] like Figures 1 to 4 As shown, the scissors-type acupuncture module replacement auxiliary device of this embodiment includes a mobile scissors-type lifter 1 and a shifting supporting mechanism 2, wherein the mobile scissors-type lifter 1 includes a lifting platform 10, a scissors-type arm 11, a power unit 12, and a walking base 13, and the shifting supporting mechanism 2 is installed on the supporting platform 10, and the shifting supporting mechanism 2 includes a slide rail 20 extending along the width direction of the supporting platform 10, a slide 21 sliding on the slide rail 20, two support frames 22 extending along the length direction of the supporting platform 10 and installed on the slide 21, and a shifting component 23 installed on the supporting platform 10 to drive the slide 21 to move horizontally.

[0034] Specifically, the walking base 13 forms walking wheels 130 from the bottom, and is further provided with a handle assembly 131 at the front end. The mobile scissor lift 1 is shifted by pushing or pulling the handle assembly 131.

[0035] In some specific embodiments, there are two slide rails 20, and the slide seats 21 correspond to the slide rails 20 one by one, and two support frames 22 are assembled in parallel on each slide seat 21. Based on the guiding support of the two slide rails 20, the displacement of the slide seat 21 is more stable, thereby satisfying the adjustment of the alignment required for assembly. In this example, the cross-section of the slide rail 20 is I-shaped. Reduce the probability of derailment. The distance between the two support frames 22 is larger than the acupuncture width formed by the acupuncture needles m1 in the acupuncture module M, and a mounting area with an open top is formed between the two support frames 22. The support height formed by each support frame 22 is larger than the length of the acupuncture needle m1. The acupuncture module M is mounted on the two support frames 22 from the opposite sides of the needle plate m2, and the acupuncture needles m1 correspond to the mounting areas above or below the needle plate m2.

[0036] In the example, the support frame 22 is capable of being adjusted along the length direction of the slide rail 20 to adjust the spacing between the support frames 22 to meet the replacement and carrying of the needle punching module of different widths. Further, the slide base 21 is provided with a butt joint hole k extending along the length direction of the slide rail 20, and the support frame 22 is assembled in position with the butt joint hole k through the outer joint part w. The adjustment of the required support spacing is completed based on the assembly in position of the butt joint hole (waist-shaped hole). Therefore, the needle punching module M is shifted in the X, Y, Z axis coordinate system based on the horizontal movement adjustment of the slide base 21, the displacement and lifting of the scissor lifter 1 to realize that the needle punching needles are upward or downward.

[0037] Further, each support frame 22 includes a frame body 220 and a shelf plate 221 located at the top of the frame body 220, wherein the width of the shelf plate 221 is smaller than the width of the frame body 220. The narrower shelf plate is adopted to form the support and reduce the contact area to facilitate the assembly of the needle punching module. The rear end of the shelf plate 221 is aligned with the rear end of the frame body 220, and the front end of the shelf plate 221 protrudes from the front end of the frame body 220 and extends forward, wherein the length of the forward extension is smaller than the length of the frame body. Based on the forward extension of the shelf plate, the effective support length is increased to meet the needs in different working conditions. In the example, the frame body is in the shape of a back-to-back character. The design of the back-to-back character mainly communicates the shelf area with the outside, and the needle punching needles can enter the shelf area to perform the assembly operation on the needle plate regardless of whether the needle punching needles are upward or downward.

[0038] In addition, the displacement assembly 23 includes a fixed seat 230 mounted on the carrying platform 10, a displacement screw rod 231 capable of rotating forward and backward around its own axis, a moving nut 232 matched with the displacement screw rod 231, and a connecting rod 233 for fixedly connecting the moving nut 232 with the slide base 21, wherein the displacement screw rod 231 is parallel to the slide rail 20, and the moving nut 232 and the slide base 21 are synchronously displaced and adjusted under the forward and backward rotation of the displacement screw rod 231. The transmission screw rod formed by the screw rod and the nut is adopted to realize the displacement adjustment, thereby more accurately assisting the assembly of the needle punching module. In the example, a hand wheel 234 is further provided at both ends of the displacement screw rod 231, and the horizontal movement fine adjustment is realized based on the rotation adjustment of the hand wheel 234 to further assist the assembly in position.

[0039] In summary, after the fork type needling module replacement auxiliary device is adopted, based on the distance between the two support frames is greater than the needling width formed by the needling needle in the needling module, the needling module to be replaced is erected on the two support frames from the opposite sides of the needle plate, and the upward or downward needling needle can be located in the corresponding erection area, then the displacement and lifting of the scissor lift moves and lifts the needling module to the designated position, and further assisted alignment can be achieved under the transverse movement adjustment of the sliding seat to complete the assembly of the needling module, therefore, on the premise that the needling needle orientation is not limited, the load carrying and transfer of the needling module can be completed, and the displacement and lifting of the scissor lift and the transverse movement adjustment of the sliding seat are used to assist the alignment and assembly of the needling module, thereby reducing the assembly difficulty; on the other hand, the accidental risk in the transfer of the needling module is effectively reduced, the damage rate of the needling needle is also reduced, and the required carrying capacity is completely provided by the scissor lift, that is, the whole assembly process is convenient and labor-saving; the third aspect is that the support frame can be adjusted in the length direction of the sliding rail to adjust the distance between the support frames, so as to meet the replacement and carrying of needling modules of different widths, and based on the alignment and assembly of the butt joint hole (waist type hole), the required support distance is adjusted; the fourth aspect is that a narrower shelf is used to form support, the contact area is reduced to facilitate the assembly of the needling module, and based on the front extension of the shelf, the effective support length is increased to meet the needs of use in different working conditions; in addition, the design of the back-to-back type mainly connects the erection area with the outside, and the upward or downward needling needle can enter the erection area to align and assemble the needle plate; the fifth aspect is that based on the guide support of the plurality of sliding rails, the displacement of the sliding seat is more stable, thereby meeting the adjustment of the required alignment degree, and the cross section of the sliding rail is in the shape of an I-beam, thereby reducing the derailment probability; the sixth aspect is that the transmission screw formed by the screw nut is used to realize displacement adjustment, thereby more accurately assisting the assembly of the needling module, and based on the rotation adjustment of the hand wheel, transverse fine adjustment is realized to further assist the assembly alignment; in addition, the handle assembly is pushed or pulled to move the needling module.
