[0036] Please refer to Figures 1 to 7 , the present invention provides an electrode sheet welding auxiliary device 20, which is used to assist in forming a solder joint protrusion 101 on the electrode sheet 10, so as to weld a connecting wire to the electrode sheet 10 through the solder joint protrusion 101. The electrode sheet 10 extends in a first direction and includes a relatively arranged first end 11 and a second end 12, and a welding part 13 located between the first end 11 and the second end 12. The solder joint protrusion 101 is formed by welding at the welding part 13. The width of the solder joint protrusion 101 is greater than the width of the assembly groove 31 on the counting cell 30, that is, the solder joint protrusion 101 will be clamped outside the assembly groove 31, so that the length dimension of the electrode sheet 10 inserted into the inner cavity of the counting cell 30 can be limited through the positioning cooperation between the solder joint protrusion 101 and the assembly groove 31. Further, by changing the position of the welding part 13 on the electrode sheet 10, the length dimension of the electrode sheet 10 inserted into the inner cavity of the counting cell 30 can be adjusted, so as to ensure the stability and accuracy of the performance of the analyzer.

[0037] In this embodiment, the electrode sheet welding auxiliary device 20 includes a bottom plate 100 and a cover plate 200. At least one groove 110 is provided on the bottom plate 100. The groove 110 is used to place the electrode sheet 10. The cover plate 200 is rotatably connected to the bottom plate 100. The cover plate 200 can cover the bottom plate 100. The first end 11 is clamped and fixed between the bottom plate 100 and the cover plate 200, and the second end 12 extends outside the end of the bottom plate 100 away from the end rotatably connected to the cover plate 200. The part to be welded 13 is positioned at the notch of the groove 110, and the solder joint protrusion 101 is formed on the part to be welded 13, which facilitates the formation of the solder joint protrusion 101, completes the precise welding of the solder joint protrusion 101, and thus ensures the accuracy of the length dimension of the electrode sheet 10 inserted into the inner cavity of the counting cell 30. By using the electrode sheet welding auxiliary device 20 in this embodiment, it is convenient for the operator to perform the welding operation, greatly saving working hours and labor costs.

[0038] Figure 1 and Figure 2 In, the direction indicated by the arrow Y is the first direction, and the direction indicated by the arrow X is the second direction.

[0039] In one embodiment, please refer to Figures 1 to 4 , the electrode sheet welding auxiliary device 20 further includes a magnetic attraction assembly 300. The magnetic attraction assembly 300 includes a first magnetic attraction member 310 and a second magnetic attraction member 320. The first magnetic attraction member 310 is installed on the bottom plate 100, and the second magnetic attraction member 320 is installed on the cover plate 200. When the cover plate 200 covers the bottom plate 100, the first magnetic attraction member 310 is magnetically connected to the second magnetic attraction member 320 to firmly clamp the electrode sheet 10 between the bottom plate 100 and the cover plate 200, ensuring the forming quality of the solder joint protrusion 101 at the part to be welded 13. The scheme of pressing the cover plate 200 and the bottom plate 100 tightly by magnetic attraction has a low cost and a simple structure.

[0040] Further, one of the first magnetic attraction member 310 and the second magnetic attraction member 320 is a magnet, and the other is a magnet or a ferrous metal, so as to achieve magnetic connection. Preferably, both the first magnetic attraction member 310 and the second magnetic attraction member 320 are magnets, which can ensure the stability and reliability of the magnetic connection. Specifically, both the first magnetic attraction member 310 and the second magnetic attraction member 320 are neodymium magnets. Further, both the first magnetic attraction member 310 and the second magnetic attraction member 320 are provided with a plurality of them, and are respectively distributed at intervals on the cover plate 200 and the bottom plate 100, so as to provide a large magnetic attraction force and ensure the stability and reliability of clamping and fixing the electrode sheet 10 between the cover plate 200 and the bottom plate 100. Specifically, both the first magnetic attraction member 310 and the second magnetic attraction member 320 are provided with two, and are symmetrically arranged on both sides of the cover plate 200 and the bottom plate 100. When using the electrode sheet welding auxiliary device 20 of this embodiment, no other auxiliary tools are required, and the welding operation can be completed conveniently and effectively.

[0041] Of course, in other embodiments, the electrode sheet welding auxiliary device 20 may further include a hinge 410 and an elastic member. The cover plate 200 is rotatably connected to the bottom plate 100 through the hinge 410. The elastic member elastically connects the cover plate 200 and the bottom plate 100 and is used to drive the cover plate 200 to cover the bottom plate 100, so as to stably clamp and fix the electrode sheet 10 between the cover plate 200 and the bottom plate 100. Specifically, the elastic member can be selected as a torsion spring.

[0042] In one embodiment, please refer to Figures 1 to 3 , a first opening 120 and a second opening 130 communicating with the groove 110 are further provided on the bottom plate 100. A limiting protrusion 210 is provided on the cover plate 200. The limiting protrusion 210 can be inserted into the groove 110 from the first opening 120 and abuts against the electrode sheet 10 to clamp and fix the first end 11 between the bottom plate 100 and the cover plate 200. The second end 12 can extend out of the groove 110 from the second opening 130. The part to be welded 13 is positioned at the second opening 130, and there is a welding gap between the second opening 130 and the limiting protrusion 210.

[0043] It can be understood that, on the one hand, through the setting of the limiting protrusion 210, it is convenient to abut the electrode sheet 10 against the groove 110 and keep it fixed, maintaining the stability and reliability of clamping and fixing the electrode sheet 10 by the cover plate 200 and the bottom plate 100. On the other hand, there is a welding gap between the second opening 130 and the limiting protrusion 210. Since the solder bump 101 has a certain volume size, during the process of performing solder joint processing at the part to be welded 13, the solder bump 101 will expand towards the first end 11 and the second end 12. At this time, through the setting of the welding gap, after the welding of the solder bump 101 is formed, it can abut against the end face of the limiting protrusion 210. The setting of the limiting protrusion 210 can ensure that the part of the electrode sheet 10 covered by the cover plate 200 is in a clean state, enabling this part of the electrode sheet 10 to be smoothly inserted into the inner cavity of the counting cell 30 through the assembly groove 31. By setting like this, it can greatly ensure that the length dimension of the electrode sheet 10 inserted into the inner cavity of the counting cell 30 is accurate enough.

[0044] Furthermore, a plurality of grooves 110 are provided in the groove 110 and are spaced along the second direction. The first direction and the second direction are arranged at an angle. Through the setting of the plurality of grooves 110, it is convenient to perform welding processing on a plurality of electrode sheets 10 in one batch to improve the efficiency of batch processing and production.

[0045] In one embodiment, please refer to Figure 1 and Figure 2 、 Figure 4, a handle part 220 is provided on the cover plate 200. The handle part 220 facilitates the operator to hold by hand, so as to turn up the cover plate 200 from the bottom plate 100. Further, an avoidance groove 230 for avoiding the hand is provided on the bottom plate 100. The avoidance groove 230 can avoid the hand of the operator, thereby further facilitating the operator to hold by hand. Moreover, through the setting of the avoidance groove 230, the handle part 220 can be arranged within the bottom plate 100, avoiding the handle part 220 protruding from the bottom plate 100, which is convenient for the space utilization of the electrode sheet welding auxiliary device 20 and the miniaturization setting. Specifically, the handle part 220 is semicircular.

[0046] In one embodiment, please refer to Figure 1 and Figure 2 , the electrode sheet welding auxiliary device 20 further includes a plurality of foot pads 500. The foot pads 500 are circumferentially and spacedly distributed at the bottom of the bottom plate 100, so as to stably support the electrode sheet welding auxiliary device 20 on the working surface through the foot pads 500.

[0047] In one embodiment, please refer to Figures 1 to 3 , the width dimension of the groove 110 is H, and the width dimension of the electrode sheet 10 is D. D + 0.08mm ≤ H ≤ D + 0.12mm, so as to realize the clearance fit between the electrode sheet 10 and the groove wall of the groove 110, so as to accurately position the electrode sheet 10 in the groove 110, which is convenient for improving the forming quality of the solder bump 101. Further, H = D + 0.08mm, D + 0.09mm, D + 0.10mm, D + 0.11mm or D + 0.12mm. Through the above dimension setting, the electrode sheet 10 can be easily inserted into the groove 110, and the electrode sheet 10 can also be accurately positioned through the groove 110.

[0048] In one embodiment, since the temperature transferred by the soldering iron during the welding of the electrode sheet 10 is as high as 300 °C, therefore, the electrode sheet welding auxiliary device 20 is a device made of a high-temperature resistant and corrosion-proof material. Specifically, the bottom plate 100 and the cover plate 200 are structural parts made of high-temperature resistant and corrosion-proof materials, and will not chemically react with the electrode sheet 10 under high-temperature conditions, so there is no need to worry about the loss of the electrode sheet 10 during the welding process.

[0049] In one embodiment, please refer to Figures 5 to 7 , the width of the assembly groove 31 on the counting pool 30 for inserting the electrode sheet 10 is 0.5mm, and the thickness of the electrode sheet 10 is 0.2mm. Since the solder bump height of the solder bump 101 is at least greater than 1mm and cannot pass through the assembly groove 31, the depth of the electrode sheet 10 inserted into the counting pool 30 can be controlled by controlling the position of the solder point of the solder bump 101 in the length direction of the electrode sheet 10, that is, the position of the part to be welded 13.

[0050] Further, please refer to togetherFigure 3 , the length of the solder bump 101 on the electrode sheet 10 can be controlled between 3.5 mm and 4.1 mm. Here, the length of the solder bump 101 is the extension length in the width direction of the electrode sheet 10. Controlling the length and position of the solder joint of the solder bump 101 on the electrode sheet 10 can control the depth of insertion of the electrode sheet 10 into the counting cell 30. Specifically, the length of the solder bump 101 on the electrode sheet 10 can be controlled at 3.5 mm, 3.6 mm, 3.7 mm, 3.8 mm, 3.9 mm, 4.0 mm or 4.1 mm.

[0051] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
