[0041] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, and without making creative labor, it is understood in the description of the utility model that the orientation or position relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like is the orientation or position relationship based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model.

[0042] In the description of the utility model, the meaning of "multiple" is two or more than two. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0043] In the description of the utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication inside two elements. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0044] In the related art, the positioning block of the jig is fixed, and the positioning block cannot be moved, so that the position of the easy-to-tear sticker is fixed. If the design of the easy-to-tear sticker and the battery is misaligned, the easy-to-tear sticker cannot be attached to the preset position of the battery, and the problem of misalignment of the easy-to-tear sticker and the battery occurs, thereby causing a large deviation between the design and the actual situation. The easy-to-tear sticker and other adhesive paper interfere with each other, so that the product does not meet the required requirements. Therefore, it is necessary to redesign the jig, the jig is relatively limited, and the production cost and production cycle will be affected.

[0045] The embodiments of the utility model will be described below in combination with Figures 1 to 9

[0046] ​The utility model discloses an embodiment provides a kind of positioning fixture 1, and positioning fixture 1 includes base 100, locating block 200 and locking seat 300.

[0047] The upper surface of base 100 is provided with battery groove 101, and battery groove 101 is used to place battery 2; locating block 200 is movably arranged on the upper surface of base 100; locating block 200 is provided with film positioning column 201; film positioning column 201 is used to cooperate with the positioning hole 31 of easy-to-tear sticker 3; locking seat 300 has first clamping part 301 and second clamping part 302; locking seat 300 can be switched between locking state and unlocking state; when locking seat 300 is in locking state, first clamping part 301 presses the lower surface of base 100, and second clamping part 302 presses the upper surface of locating block 200; when locking seat 300 is in unlocking state, first clamping part 301 and second clamping part 302 loosen base 100 and locating block 200; for example, first clamping part 301 is separated from the lower surface of base 100, or second clamping part 302 is separated from the upper surface of locating block 200, or first clamping part 301 is separated from the lower surface of base 100, and second clamping part 302 is separated from the upper surface of locating block 200.

[0048] Specifically, locking seat 300 can be multiple; multiple locking seats 300 are arranged along the length direction of locating block 200; in this way, the positioning points between locating block 200 and base 100 can be improved, so as to reduce the probability of relative displacement between locating block 200 and base 100, and improve the stability of relative position between locating block 200 and base 100.

[0049] When positioning fixture 1 is used, first, adjust locking seat 300 to unlocking state; adjust the relative position between locating block 200 and base 100 according to the relative position of battery 2 and easy-to-tear sticker 3; then, adjust locking seat 300 to locking state, fix the relative position between locating block 200 and base 100; place battery 2 in battery groove 101; cooperate the positioning hole 31 of easy-to-tear sticker 3 with film positioning column 201, fix the relative position of battery 2 and easy-to-tear sticker 3; finally, connect and fix battery 2 and easy-to-tear sticker 3.

[0050] In the above process, for the same type of battery 2 and easy-to-tear sticker 3, the relative position between locating block 200 and base 100 can be adjusted only once at the beginning; subsequently, the same type of battery 2 and easy-to-tear sticker 3 can be directly positioned by positioning fixture 1; when it is necessary to apply positioning fixture 1 to another type of battery 2 and easy-to-tear sticker 3, the relative position between locating block 200 and base 100 can be adjusted again; subsequently, the new type of battery 2 and easy-to-tear sticker 3 can be positioned.

[0051] The positioning fixture 1 of this utility model allows the positioning block 200 to be displaced relative to the base 100 by adjusting the locking seat 300 to the unlocked state, thus changing the position of the positioning block 200 to adapt to the relative position between the battery 2 and the easy-tear sticker 3. Then, by adjusting the locking seat 300 to the locked state, the relative position between the positioning block 200 and the base 100 is fixed. The positioning hole 31 of the easy-tear sticker 3 fits onto the film positioning post 201, allowing the easy-tear sticker 3 to be attached to the required position on the battery 2. The relative position of the easy-tear sticker 3 and the battery 2 can be adjusted according to requirements, enabling the easy-tear sticker 3 to be positioned in various ways. Thus, one fixture can attach easy-tear stickers 3 of different sizes and positions, greatly improving the versatility of the positioning fixture 1.

[0052] For example, the base 100 may be provided with a pick-up and put-down notch 103, which may be located on opposite sides of the base 100. The pick-up and put-down notch 103 is located below a portion of the battery 2. An operator or operating device can apply force to the battery 2 through the pick-up and put-down notch 103 to facilitate the placement of the battery 2 in the battery slot 101 and the removal of the battery 2 from the battery slot 101.

[0053] like Figure 9 As shown, in the technical solution of this embodiment, the locking seat 300 includes a bracket 310 and a threaded component 320. The bracket 310 includes a lower plate 311, an upper plate 312 and a connecting plate 313. The lower plate 311 and the upper plate 312 are both connected to the connecting plate 313. The lower plate 311 is located below the base 100. A first clamping part 301 is formed on the lower plate 311. The upper plate 312 is located above the base 100 and is provided with a threaded hole 314. The threaded component 320 is threadedly connected to the hole wall of the threaded hole 314. A second clamping part 302 is formed at the lower end of the threaded component 320.

[0054] The bracket 310 is constructed in a "U" shape, with the connecting plate 313 located outside the base 100. The bracket 310 forms a semi-enclosed structure around the base 100 and the positioning block 200. By rotating the threaded component 320, the threaded component 320 can move upward or downward relative to the positioning block 200. For example, when viewed from above, rotating the threaded component 320 in the forward direction moves it upward relative to the positioning block 200, while rotating it in the reverse direction moves it downward relative to the positioning block 200. This allows for contact and separation between the second clamping part 302 and the positioning block 200, and the structure is simple and easy to operate.

[0055] like Figure 9As shown, in the technical solution of this embodiment, the threaded component 320 includes an operating cap 321, a threaded rod 322, and an enlarging component 323. The operating cap 321 is located above the upper plate 312. The threaded rod 322 is threadedly connected to the wall of the threaded hole 314. The upper end of the threaded rod 322 is connected to the operating cap 321. The diameter of the threaded rod 322 is smaller than the diameter of the operating cap 321. The enlarging component 323 is connected to the lower end of the threaded rod 322. The diameter of the lower end of the enlarging component 323 is larger than the diameter of the lower end of the threaded rod 322. The second clamping part 302 is formed at the lower end of the enlarging component 323.

[0056] Both the threaded rod 322 and the enlarger 323 can be made of metal. The threaded rod 322 and the enlarger 323 can be welded together to increase the connection strength between the threaded rod 322 and the enlarger 323 and reduce the probability of separation between the threaded rod 322 and the enlarger 323.

[0057] By setting the operating cap 321, the contact area between the operator and the threaded part 320 is large, making it easier for the operator to apply rotational force to the threaded part 320, and the threaded part 320 is easier to rotate. By setting the threaded rod 322, a threaded connection can be achieved between the threaded part 320 and the hole wall of the threaded hole 314, and the cost can be reduced due to the reduced diameter of the threaded part 320. By setting the enlarging part 323, the contact area between the threaded part 320 and the positioning block 200 can be increased, and the positioning effect of the threaded part 320 on the positioning block 200 is better.

[0058] In addition, the threaded rod 322 and the operating cap 321 can be integrally formed. After the threaded rod 322 is threaded to the wall of the threaded hole 314, the threaded rod 322 and the enlarger 323 are connected. On the one hand, it is convenient to realize the fit between the threaded rod 322 and the wall of the threaded hole 314. On the other hand, the enlarger 323 and the operating cap 321 will not pass through the threaded hole 314, which can limit the relative position between the threaded part 320 and the base 100.

[0059] like Figure 9 As shown in the technical solution of this embodiment, the outer peripheral surface of the operating cap 321 is provided with a plurality of protruding ribs 3211, which are spaced apart circumferentially along the operating cap 321, and each protruding rib 3211 extends axially along the operating cap 321. In this way, the friction of the outer peripheral surface of the operating cap 321 can be increased, preventing slippage between the operator or operating equipment and the operating cap 321, and improving the ease of rotation.

[0060] like Figure 9As shown, in the technical solution of this embodiment, the enlarging member 323 includes a gradient part 3231 and an enlarging plate 3232. The upper end of the gradient part 3231 is connected to the lower end of the threaded rod 322. The diameter of the gradient part 3231 gradually increases from top to bottom. The enlarging plate 3232 is connected to the lower end of the gradient part 3231. The diameter of the enlarging plate 3232 is greater than the diameter of the lower end of the gradient part 3231. The thickness of the enlarging plate 3232 is less than the thickness of the gradient part 3231.

[0061] The gradient portion 3231 and the enlarged piece 3232 can be integrally formed structures, and the gradient portion 3231 can be constructed as a frustum or a frustum of other shapes.

[0062] Because the diameter of the gradient portion 3231 gradually changes, a step-like structure can be avoided in the gradient portion 3231. Furthermore, the large contact area between the gradient portion 3231 and the enlarging plate 3232 prevents localized stress concentration in the enlarging member 323, reducing the probability of stress concentration and thus making the enlarging member 323 less prone to damage. In addition, since the thickness of the enlarging plate 3232 is less than the thickness of the gradient portion 3231, the enlarging member 323 has a smaller volume, reducing cost and weight.

[0063] like Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, in the technical solution of this embodiment, there are multiple film positioning posts 201, which are arranged at intervals along the extension direction of the positioning block 200. This results in more connection points between the positioning block 200 and the easy-tear adhesive 3, improving the positioning effect between them and reducing the probability of misalignment between their relative positions.

[0064] like Figure 7 As shown, in the technical solution of this embodiment, the positioning block 200 includes a middle section 210 and two widening sections 220. The second clamping part 302 abuts against the upper surface of the middle section 210. The two widening sections 220 are connected to the two ends of the middle section 210 in a one-to-one correspondence. The widening section 220 is located on the side of the middle section 210 facing the battery slot 101. Each widening section 220 is provided with a film-attached positioning post 201.

[0065] Among them, the two widening sections 220 can be located on opposite sides of the battery slot 101. The easy-tear sticker 3 has a raised part 32, which is located at the corner of the easy-tear sticker 3 and above the widening section 220. The raised part 32 is provided with a positioning hole 31, so that the positioning effect between the easy-tear sticker 3 and the positioning block 200 is better.

[0066] In this way, the film positioning column 201 is closer to the easy-to-tear sticker 3, and the spacing between the easy-to-tear sticker 3 and the locking seat 300 can be increased to avoid interference between the easy-to-tear sticker 3 and the locking seat 300, thereby improving assembly efficiency.

[0067] As shown in Figure 6 , in the technical solution of the present embodiment, the size of the positioning block 200 in the length direction is greater than the size of the base 100. In this way, in the length direction of the positioning block 200, a part of the positioning block 200 will exceed the base 100, and the operator or operating equipment has a large contact area with the positioning block 200, which is beneficial for the operator to hold the positioning block 200, thereby making it more convenient to adjust the relative position between the positioning block 200 and the base 100, and the positioning precision between the positioning block 200 and the base 100 is higher.

[0068] As shown in Figure 1 , Figure 3 , Figure 5 and Figure 6 , in the technical solution of the present embodiment, the positioning jig 1 further comprises a first gasket 400 arranged between the first clamping portion 301 and the lower surface of the base 100. The first gasket 400 has elasticity, for example, the first gasket 400 is a silica gel pad or a rubber pad. On the one hand, it can avoid hard contact between the first clamping portion 301 and the base 100, reduce the damage probability of the first clamping portion 301 and the base 100, and reduce the noise generated due to collision, and on the other hand, it can fill the gap between the first clamping portion 301 and the base 100, improve the reliability of the contact between the first clamping portion 301 and the base 100, and ensure the clamping effect.

[0069] As shown in Figure 1 , Figure 3 , Figure 5 and Figure 6 , in the technical solution of the present embodiment, the positioning jig 1 further comprises a second gasket 500 arranged between the second clamping portion 302 and the upper surface of the positioning block 200. The second gasket 500 has elasticity, for example, the second gasket 500 is a silica gel pad or a rubber pad. On the one hand, it can avoid hard contact between the second clamping portion 302 and the base 100, reduce the damage probability of the second clamping portion 302 and the base 100, and reduce the noise generated due to collision, and on the other hand, it can fill the gap between the second clamping portion 302 and the base 100, improve the reliability of the contact between the second clamping portion 302 and the base 100, and ensure the clamping effect.

[0070] As shown in Figure 1 , Figures 3 to 5 , Figure 7 and Figure 8As shown, in the technical scheme of the embodiment, the positioning jig 1 further comprises a limiting block 600 and an elastic member (not shown in the figure), the bottom of the battery groove 101 is provided with a limiting groove 102, the limiting groove 102 and the positioning block 200 are located on opposite sides of the battery groove 101, the limiting block 600 is movably arranged in the limiting groove 102, the limiting block 600 is used for abutting against the battery 2, and the elastic member abuts between the side of the limiting block 600 away from the positioning block 200 and the side wall of the battery groove 101.

[0071] Specifically, the side of the battery 2 close to the positioning block 200 is provided with a tab 21, the side wall of the battery groove 101 close to the positioning block 200 is provided with an avoiding groove 105, and the tab 21 is placed in the avoiding groove 105, wherein the tab 21 is two, one tab 21 is a positive tab, and the other tab 21 is a negative tab, and the avoiding groove 105 is also two, and the two tabs 21 are placed in the two avoiding grooves 105.

[0072] In addition, the side of the battery 2 away from the positioning block 200 abuts against the limiting block 600, the limiting block 600 compresses the elastic member, the elastic member elastically deforms, the elastic member applies an elastic force to the limiting force in the direction of the battery 2, so that the limiting block 600 and the side wall of the battery groove 101 clamp the battery 2, and the relative position between the battery 2 and the base 100 is kept stable, so that the base 100 can cooperate with batteries 2 of different sizes. Wherein, when the battery 2 is not placed in the battery groove 101, the elastic member can be in an elastic deformation state.

[0073] By arranging the limiting groove 102, on the one hand, the relative position between the limiting block 600 and the base 100 can be limited, and on the other hand, the battery 2 contacts the center of the height direction of the limiting block 600, which can improve the reliability of the contact between the limiting block 600 and the battery 2, and avoid the rotation of the limiting block 600 relative to the battery 2.

[0074] For example, the side wall of the battery groove 101 away from the positioning block 200 is provided with a first guide hole 104, the limiting block 600 is provided with a second guide hole 610, the film positioning column 201 (not shown in the figure) passes through the first guide hole 104 and the second guide hole 610, and the elastic member can be sleeved on the guide column (not shown in the figure). The limiting block 600 moves along the length direction of the guide column, and the guide column can avoid the deflection of the elastic member, and ensure that the movement path of the limiting block 600 meets the expectation.

[0075] Wherein, the first guide hole 104, the second guide hole 610 and the film positioning column 201 can all be multiple, and the multiple first guide holes 104, the multiple second guide holes 610 and the multiple film positioning columns 201 are arranged one by one, so as to avoid the rotation of the limiting block 600 and improve the reliability of the displacement of the limiting block 600.
