[0002] In the automated production process of batteries, due to the high requirement for battery positioning accuracy, automated equipment needs to accurately position the batteries. Battery positioning failure will lead to battery scrapping or the risk of short-circuit discharge in subsequent production processes.

[0003] In the prior art for battery positioning, it is usually for cylindrical batteries. An arc-shaped limiting groove that fits the cylindrical surface of the battery is designed in the positioning vehicle to achieve the embedding and positioning of the battery. However, even for batteries of the same specification batch, the dimensions of the batteries have a certain upper and lower tolerance. There is only one intersecting surface contact between the cylindrical battery and the arc-shaped limiting groove. If the battery size is small, when the battery is embedded in the limiting groove, the contact of one intersecting surface cannot ensure the complete positioning of the battery, which will cause the battery that should be restricted to shake and shift, unable to achieve accurate positioning, thus affecting subsequent production and resulting in problems such as low yield, material waste, and high production costs.

[0004] Therefore, it is necessary to design a positioning transfer vehicle for batteries to solve the above problems. Utility Model Content

Detailed implementation manners

[0027] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part rather than all of the embodiments of the present application. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0028] In the description of the embodiments of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of this application is usually placed when in use. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present application. In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0029] In addition, terms such as "horizontal" and "vertical" do not mean that the components are required to be absolutely horizontal or hanging, but can be slightly inclined. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0030] In the description of the embodiments of the present application, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0031] According to a first aspect of the present invention, a positioning and transferring carrier for a battery is provided, as Figures 1 to 7 shown. The positioning and transferring carrier for a battery is used for positioning the battery, and is particularly suitable for positioning cylindrical batteries. The positioning and transferring carrier for a battery includes a positioning frame body 1.

[0032] In the following description, reference will be made to Figures 1 to 7 specifically describe the detailed structure of the positioning frame body 1 of the positioning and transferring carrier for a battery. In addition, in the description of the embodiments, two directions are also involved, namely the first direction S1 and the second direction S2. The first direction S1 can be understood as the direction from bottom to top in Figure 1 and Figure 2 , and can also be understood as the direction of the positioning frame body 1 from one end to the other end in the height direction; the second direction S2 can be understood as the direction of the positioning frame body 1 from one end to the other end in the length direction. It should also be noted that for the convenience of description and illustration in the figure, the battery mentioned above is the battery body 6 in the description of the embodiments.

[0033] As Figures 1 to 4 shown, in the embodiment, the positioning frame body 1 is used to carry and fix the battery body 6. Since the battery body 6 is formed into a cylindrical structure and has a certain length, the positioning frame body 1 accordingly has a certain height to adapt to the battery body 6. In battery production, in the previous process, the battery body 6 is transported to the positioning frame body 1 through a transmission device (not shown, which can be a device in the prior art) to realize the fixation of the battery body 6. Therefore, an opening is provided at one end of the positioning frame body 1 facing the receiving direction of the battery body 6, and the opening can be used for receiving and accommodating the battery body 6.

[0034] Furthermore, the opening can be formed into a positioning groove 2, and the positioning groove 2 is in direct contact with the battery body 6. The positioning groove 2 includes a plurality of positioning surfaces, such as a positioning base surface 201 and a positioning side surface 202. The positioning base surface 201 and the positioning side surface 202 can both be formed into rectangular structures, and these three surfaces can all be in contact with the battery body 6. The positioning side surface 202 is arranged on both sides of the positioning base surface 201, and an included angle is formed between the positioning side surface 202 and the positioning base surface 201. From as Figure 6 and Figure 7From the perspective of the top view shown, the inner sidewall of the positioning groove 2 can be formed into an unclosed polygon. In the embodiment, a positioning side surface 202, a positioning base surface 201, and another positioning side surface 202 connected in sequence can be formed into an unclosed isosceles trapezoid.

[0035] In this way, when the battery body 6 is fixed on the positioning frame body 1, it can at least abut against the positioning side surface 202. In the embodiment, the number of the positioning side surfaces 202 is two. In this way, when the battery body 6 is positioned, it can have at least two intersecting surfaces with the positioning frame body 1, and these two intersecting surfaces can clamp and position the battery body 6 to realize the positioning and locking of the cylindrical battery body 6, and can also prevent the battery body 6 from shaking and shifting.

[0036] Figure 6 and Figure 7 The difference from Figure 6 is that: Figure 7 the diameter dimension of the battery body 6 in Figure 6 is greater than the diameter dimension of the battery body 6 in Figure 7 the diameter dimension of the battery body 6 in Figure 6 is the upper limit acceptable for manufacturing tolerance, and the diameter dimension of the battery body 6 in Figure 7 is the lower limit acceptable for manufacturing tolerance. Since the size of the positioning groove 2 is fixed, in actual operation, when positioning the battery body 6, if the diameter dimension of the battery body 6 is larger, that is, as shown in Figure 6 or Figure 7 shown, the battery body 6 will abut against the two positioning side surfaces 202, and there will be a small gap between it and the positioning base surface 201 to form two intersecting surfaces. If the diameter dimension of the battery body 6 is smaller, as shown in

[0037] shown, the battery body 6 will abut against the two positioning side surfaces 202 and a positioning base surface 201 to form three intersecting surfaces. And either of the two cases in

[0038] can satisfy the positioning of the battery body 6. However, it is not limited to this. More positioning side surfaces 202 can also be set according to the structure of the positioning transfer device, and an included angle is formed between every two adjacent positioning side surfaces 202, so that the positioning of the battery body 6 is more stable and accurate, and the battery body 6 is prevented from shaking and shifting.

[0037] Through the cooperation of the positioning frame body 1 and the battery body 6, the positioning transfer carrier for the battery enables the battery body 6 to be accurately and stably positioned and clamped inside the positioning groove 2 of the positioning frame body 1. When being clamped, the battery body 6 can at least abut against the positioning side surface 202 of the positioning groove 2, and the battery body 6 is clamped and fixed to the positioning frame body 1 through the positioning side surface 202 to realize accurate positioning, prevent the battery body 6 from shaking and shifting during positioning, thereby affecting subsequent production, and solve the problems of low qualified product rate, material waste, and high production cost caused by inaccurate positioning of the battery body 6.

[0038] Preferably, as Figures 1 to 3 shown, in the embodiment, the positioning frame body 1 is further provided with a strengthening positioning portion. The strengthening positioning portion faces away from the positioning base surface 201, and a magnetic member is arranged inside the strengthening positioning portion. The magnetic member is arranged inside the strengthening positioning portion, which can avoid direct contact with the battery body 6. The magnetic member contacts the battery body 6 through the positioning base surface 201 (this contact can be understood as magnetic attraction). Since the magnetic member has magnetism, during the production process, ferromagnetic foreign matters will be adsorbed on the magnetic member and are not easy to clean. Therefore, in order to prevent these foreign matters from contacting the battery body 6, scratching and damaging the surface of the battery body 6, which may further lead to poor appearance of the battery body 6, the magnetic member does not directly contact the battery body 6.

[0039] Furthermore, the magnetic member can be, for example, a magnet, which can generate a magnetic attraction effect with the battery body 6, thereby attracting the battery body 6. The strengthening positioning portion provided with the magnetic member can make the battery body 6 more accurate and stable during positioning. The strengthening positioning portion can also assist in positioning when the diameter size of the battery body 6 is large and it cannot abut against the positioning base surface 201, to prevent the battery body 6 from shaking and shifting. In addition, it should also be noted that considering the magnetic attraction effect, the micro-gap (in the above, as Figure 6 shown, the battery body 6 will abut against the two positioning side surfaces 202, and a micro-gap is formed between the battery body 6 and the positioning base surface 201) cannot be too large, otherwise it will affect the positioning effect.

[0040] Furthermore, when the battery body 6 abuts against the positioning side surfaces 202, an intersecting surface is formed between the battery body 6 and the positioning side surfaces 202, and a gap (i.e., the above-mentioned micro-gap) is formed between the battery body 6 and the positioning base surface 201. For this micro-gap, a standard setting is made, and the corresponding explanations are given in the two cases as shown in Figure 6 and Figure 7 shown.

[0041] As Figure 6 shown in the first case, the battery body 6 abuts against the two positioning side surfaces 202 to form two intersecting surfaces and a micro-gap. As Figure 7 shown in the second case, the battery body 6 can abut against the two positioning side surfaces 202 and the positioning base surface 201 simultaneously to form three intersecting surfaces (it can also be understood that the micro-gap is 0 at this time).

[0042] Further, the size of the micro-gap is set as d, and the radius of the cylindrical battery is D. In the above two cases, 0 ≤ d / D ≤ 0.05. Preferably, 0 ≤ d / D ≤ 0.03, and more preferably, 0 ≤ d / D ≤ 0.01. In the first case, 0 < d / D ≤ 0.05, preferably, 0 < d / D ≤ 0.03, and more preferably, 0 < d / D ≤ 0.01. Such a size setting can make the positioning of the battery body 6 more accurate, and after positioning, there will be no situations such as shaking and displacement due to too large a gap and weakening of the magnetic adsorption force.

[0043] Preferably, as Figure 1 shown, in the embodiment, the magnetic member can be formed into a strip-shaped structure, and the strengthening positioning portion is formed into an oval hole 203.

[0044] Preferably, as Figure 1 shown, in the embodiment, the positioning base surface 201 is provided with a through hole 204, and the through hole 204 penetrates through the positioning base surface 201 and communicates with the strengthening positioning portion.

[0045] Since the positioning groove 2 has a certain length in the first direction S1, the strengthening positioning portion can correspondingly be formed into an oval hole 203. Similarly, the magnetic member can also be formed into a strip-shaped structure. Further, the strip-shaped magnetic member can be arranged in the oval hole 203 by an adhesive method. After the magnetic member is used for a period of time and its magnetism weakens or it breaks and needs to be replaced, it is difficult to replace due to the adhesive method (since the magnetic member is installed by gluing and sinks into the oval hole 203 after installation). Therefore, a through hole 204 is additionally provided. The user can use a cleaning tool such as a rod-shaped one to pierce through the through hole 204 from the opening portion towards the strengthening positioning portion to replace or clean the magnetic attraction member. Since the adhesive method is adopted, after the adhesion is completed, the through hole 204 will be blocked by glue, which also avoids the direct contact between the magnetic member and the battery body 6.

[0046] The strip-shaped magnetic member can match a cylindrical battery with larger length and diameter dimensions. The magnetic attraction force of the magnetic member and the clamping force of the positioning side surface 202 can accurately position the battery body 6 on the positioning frame body 1, and prevent the battery body 6 from shaking and displacing.

[0047] Preferably, as Figures 1 to 5As shown, in the embodiment, the positioning and transferring carrier for the battery further includes a mounting block 3, and the mounting block 3 is arranged at the end of the positioning frame body 1 in the first direction S1. The mounting block 3 can be arranged at the end of the positioning frame body 1 in the length direction, and the positioning frame body 1 can be mounted at the set position of the positioning and transferring device through the mounting block 3. Further, the mounting block 3 is provided with a mounting hole 301. The mounting hole 301 can be, for example, a screw hole or a pin hole, and the user can mount the mounting block 3 at the set position through the mounting hole 301 by means of screw connection or pin connection.

[0048] Preferably, as Figures 1 to 5 shown, in the embodiment, the mounting block 3 can be integrally formed with the positioning frame body 1. The integrally formed mounting block 3 and positioning frame body 1 have high structural strength and stable installation.

[0049] Preferably, as Figures 1 to 5 shown, in the embodiment, a supporting member 4 is arranged at one end of the positioning groove 2 in the first direction S1. The supporting member 4 is connected to the positioning base surface 201 and the positioning side surface 202. When the battery body 6 is arranged on the positioning frame body 1, one end of the battery body 6 abuts against the supporting member 4. The supporting member 4 can bear the battery body 6 to prevent the battery body 6 from falling, and at the same time can also keep the battery body 6 stable in the axial direction of the battery body 6.

[0050] Preferably, as Figure 1 shown, in the embodiment, a through groove 401 is formed in the middle of the supporting member 4. When one end of the battery body 6 abuts against the supporting member 4, the electrode of the battery body 6 is located in the through groove 401 so that the electrode of the battery body 6 is exposed. The through groove 401 can avoid blocking the electrode end of the battery body 6 and is convenient for subsequent operations.

[0051] Through the cooperation of the positioning frame body and the battery body, the positioning and transferring carrier for the battery enables the battery body to be accurately and stably positioned and clamped inside the positioning groove of the positioning frame body. When being clamped, the battery body can at least abut against the positioning side surface of the positioning groove, and the battery body is received and fixed to the positioning frame body through the positioning side surface, realizing accurate positioning, avoiding shaking and displacement of the battery body during positioning, thereby affecting subsequent production, and solving the problems of low yield, material waste and high production cost caused by inaccurate positioning of the battery body.

[0052] In addition, according to the second aspect of the present invention, a positioning and transferring device is provided. The positioning and transferring device includes the positioning and transferring carrier for the battery as described above. The positioning and transferring carrier for the battery will be driven by the moving component of the positioning and transferring device during operation and move among different workstations to realize the movement of the battery body 6.

[0053] Preferably, as Figure 4 andFigure 5 As shown, the positioning and transfer device further includes a positioning push block 5, and the positioning push block 5 can push the battery body 6 located on the positioning frame body 1, so that the battery body 6 is separated from the positioning frame body 1, and then reaches the next working station.

[0054] Preferably, as Figure 2 , Figure 4 and Figure 5 shown, in the embodiment, avoidance grooves 205 are provided on both sides of the opening part in the second direction S2. One end of the positioning push block 5 facing the positioning frame body 1 is provided with a clamping part. When the positioning push block 5 is connected to the positioning frame body 1, the clamping part is clamped in the avoidance groove 205 to push the battery body 6.

[0055] Preferably, as Figure 2 , Figure 4 and Figure 5 shown, in the embodiment, the clamping part may include a first clamping block part 501 and a second clamping block part 502. One surface of the first clamping block part 501 facing the positioning frame body 1 is formed as a positioning groove 2. A fastening groove 503 for avoiding the strengthening positioning part is formed in the middle of the second clamping block part 502. The inner side wall of the second clamping block part 502 connected to the middle is formed as a positioning side surface 202. In order to facilitate pushing the battery body 6, the structures of the first clamping block part 501 and the second clamping block part 502 are similar to the structure of the positioning frame body 1, and both may at least include a positioning side surface 202, and the battery body 6 is pushed through the positioning side surface 202 of the positioning push block 5.

[0056] Preferably, in order to facilitate pushing the battery body 6, the included angle between the positioning side surface 202 of the positioning push block 5 and the positioning base surface 201 (the positioning side surface 202 and the positioning base surface 201 in the first clamping block part 501, and the positioning side surface 202 and the middle part forming the fastening groove 503 in the second clamping block part 502) is different from the included angle between the positioning side surface 202 and the positioning base surface 201 of the positioning frame body 1.

[0057] Through the cooperation of the positioning push block 5 and the positioning frame body 1, the positioning and transfer device can conveniently push the battery body 6, and at the same time can also make the positioning of the battery body 6 accurate and stable, ensuring the accuracy and efficiency of subsequent production.

[0058] Finally, it should be noted that the above-described embodiments are only specific embodiments of the present application, which are used to illustrate the technical solutions of the present application, rather than limiting it.
