[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] To clearly understand the technical solution of this application, the solutions of the prior art will be described in detail first.

[0024] In the field of battery manufacturing for digital products such as headphones, mobile phones, and computers, batteries need to be tightly assembled with battery holders (such as plastic casings) to ensure secure contact, safe power supply, and prevent loosening or short circuits, thus ensuring the stable operation of electrical equipment.

[0025] In battery manufacturing, traditional processes often employ manual or semi-automatic assembly methods, which suffer from problems such as insufficient battery positioning accuracy, high battery holder deformation rate, and unstable sealing. To address these issues, current manufacturing processes mostly utilize automated assembly methods for automated battery processing.

[0026] like Figure 1As shown, the battery includes: a connector 210, an output component 220, and two battery bodies 230. The two battery bodies 230 are electrically connected through the connector 210. The output component 220 is electrically connected to one of the battery bodies 230 and is used for charging and discharging the battery.

[0027] When processing the battery, the two battery bodies 230 need to be flipped relative to each other so that the geometry of the battery matches the geometry of the battery holder, thereby ensuring a tight fit between the battery and the battery holder and meeting the requirements of the electrical equipment for the battery's geometric dimensions.

[0028] like Figure 2 As shown, after processing, the two battery bodies 230 are flipped relative to each other, and the connector 210 is bent synchronously with the flipping of the battery bodies 230. During the bending process of the connector 210, uneven plastic deformation is formed on the inner and outer sides of the bend, resulting in high local stress concentration. The connector 210 is prone to substrate delamination or microcracks due to stress concentration, which in turn leads to electrical connection failure.

[0029] Therefore, in response to the above-mentioned technical problems, the research found that, in order to solve the problem, after the connector is bent synchronously with the flip of the main body, the connector is shaped as a whole, so that the connector undergoes a small amount of plastic flow, eliminating the stress peak area, and thus making the stress evenly distributed, thereby achieving the purpose of a stable electrical connection.

[0030] The technical solutions of this application will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0031] like Figures 1 to 4 As shown, the battery processing equipment is used to process batteries. The battery includes a connector 210 and two battery bodies 230, which are electrically connected through the connector 210. The battery processing equipment includes a fixed mounting platform 110, a holding mechanism 120, and a shaping mechanism 130. The battery processing equipment has a first direction x and a second direction y that are perpendicular to each other. The holding mechanism 120 includes a first holding sub-mechanism 121 and a second holding sub-mechanism 122, which are spaced apart along the first direction x. The first holding sub-mechanism 121 and the second holding sub-mechanism 122 are movably connected to the fixed mounting platform 110 and can rotate relative to the fixed mounting platform 110 around the second direction y. The first holding sub-mechanism 121 and the second holding sub-mechanism 122 are used to hold the battery bodies and drive the battery bodies to rotate. The shaping mechanism 130 is movably connected to the fixed mounting platform 110 and can move relative to the holding mechanism 120. The shaping mechanism 130 is used to shape the connector.

[0032] This application provides a battery processing device that uses a shaping mechanism to shape the battery connectors, achieving a uniform stress distribution and preventing substrate delamination or micro-cracks due to stress concentration, thus improving the reliability of the battery electrical connection. By moving the shaping mechanism relative to the holding mechanism, the shaping mechanism is positioned to a preset location for shaping the connectors, enabling flexible positioning and improving the shaping effect. The holding mechanism holds and flips the battery body, causing the connectors to bend synchronously, improving the consistency of the bending process.

[0033] Specifically, the first direction x can be understood as the horizontal left-right direction, and its positive direction can be from horizontal left to horizontal right, or from horizontal right to horizontal left; the second direction y is perpendicular to the first direction x, and can be understood as the horizontal front-back direction, and its positive direction can be from horizontal forward to horizontal backward, or from horizontal backward to horizontal forward.

[0034] The holding mechanism 120 includes a first holding sub-mechanism 121 and a second holding sub-mechanism 122. Holding refers to fixing and clamping, that is, using the holding sub-mechanism to firmly grasp and position the battery body 230, keeping it stable and preventing it from moving, shaking, or falling off during subsequent processing. The first holding sub-mechanism 121 and the second holding sub-mechanism 122 can have the same or different structures. For example, both can be pneumatic grippers, servo gripping arms, or elastic clamp structures, etc., clamping one end of the battery body 230 through synchronous action to achieve symmetrical holding and facilitate flipping control; or, for example, the first holding sub-mechanism 121 is an active drive clamp to provide rotational power, and the second holding sub-mechanism 122 is a follow-up support clamp to assist in supporting and maintaining the stability of the battery and prevent deformation.

[0035] The first holding sub-mechanism 121 and the second holding sub-mechanism 122 are spaced apart along the first direction x, meaning that the first holding sub-mechanism 121 and the second holding sub-mechanism 122 are arranged separately in the first direction x, with a certain distance between them. The spaced arrangement helps to improve the holding stability and prevent torsional imbalance during the flipping process; at the same time, the distance between them is greater than the length of the battery body 230, so that after the battery is inserted, its two ends are respectively held by the first holding sub-mechanism 121 and the second holding sub-mechanism 122.

[0036] Regarding the first holding sub-mechanism 121, it is movably connected to the fixed mounting platform 110 and can rotate relative to the fixed mounting platform 110 about the second direction y. Here, "movably connected" means that the first holding sub-mechanism 121 can move relative to the fixed mounting platform 110. Specific connection methods may include shaft connection, hinge structure connection, or slewing bearing, etc. The principle of relative rotation can be achieved by driving the shaft through a servo motor and reducer, or by directly outputting rotational force through a pneumatic or hydraulic rotary cylinder, thereby achieving angle-controllable rotation, such as 90° rotation or 180° rotation.

[0037] The first holding sub-mechanism 121 holds a battery body 230 by means of clamping, adsorption or clamping, and drives the battery body 230 to rotate relative to the fixed mounting platform 110 around the second direction y.

[0038] The second holding sub-mechanism 122 is movably connected to the fixed mounting platform 110 and can rotate relative to the fixed mounting platform 110 around the second direction y. The second holding sub-mechanism 122 is used to hold the battery body 230 and drive the battery body 230 to rotate. This situation is similar to the first holding sub-mechanism 121, and will not be described in detail in the embodiments of this application.

[0039] After the two battery bodies 230 are flipped relative to each other, the connector 210 is bent synchronously with the flipping of the battery bodies 230, so the connector 210 needs to be reshaped.

[0040] The shaping mechanism 130 is movably connected to the fixed mounting platform 110 and can move relative to the holding mechanism 120. This movable connection means that the shaping mechanism 130 can move relative to the holding mechanism 120. Specific connection methods may include linear guide and slider structures, ball screw drive structures, or cylinder / electric cylinder push structures. The principle of relative sliding can be achieved by using a motor to drive the screw to move the slide table, or by using a cylinder / electric cylinder to push the shaping head to extend or retract, thereby achieving linear movement along a first direction x, a second direction y, or a third direction z perpendicular to both the first and second directions x and y, or achieving multi-degree-of-freedom combined movement.

[0041] If the shaping mechanism 130 moves to the first preset position, it indicates that the current position of the shaping mechanism 130 can shape the connector 210. Then the shaping mechanism 130 uses bending shaping, flattening shaping or forming stamping to shape the connector 210, so that the connector 210 undergoes plastic deformation to achieve the target size and shape.

[0042] After the battery processing equipment completes the battery processing, theoretically, the battery's geometry can be adapted to the geometry of the battery holder. Subsequently, other automated or semi-automated equipment can be used to assemble the battery into the battery holder, achieving a tight fit between the two.

[0043] When the shaping mechanism 130 shapes the connector 210 by flattening, the flipped battery body 230 will obstruct the flattening process on one side of the connector 210. Based on this, the shaping mechanism 130 moves to the first preset position by using a multi-degree-of-freedom combination movement method while avoiding the battery body 230, and shapes the connector 210 at the first preset position.

[0044] Optionally, such as Figures 1 to 4 As shown, the battery processing equipment also has a third direction z, which is perpendicular to the first direction x and the second direction y. The shaping mechanism 130 includes: a first shaping component 131 and a second shaping component 132; the first shaping component 131 is disposed on one side of the holding mechanism 120 along the third direction z, the first shaping component 131 is movably connected to the fixed mounting table 110, and can move relative to the holding mechanism 120 along the third direction z; the second shaping component 132 is disposed on one side of the holding mechanism 120 along the second direction y, the second shaping component 132 is movably connected to the fixed mounting table 110, and can move relative to the holding mechanism 120 along the second direction y. The first shaping component 131 and the second shaping component 132 cooperate to shape the connector.

[0045] In the embodiments of this application, the beneficial effects are as follows: the movement of the first shaping component relative to the holding mechanism along a third direction and the movement of the second shaping component relative to the holding mechanism along a second direction, through the cooperation of the two, the connector is shaped while avoiding the battery body.

[0046] Specifically, the third direction z can be understood as the vertical up and down direction. Its positive direction can be from vertically downward to vertically upward, or from vertically upward to vertically downward.

[0047] The first shaping member 131 is movably connected to the fixed mounting platform 110 and can move relative to the holding mechanism 120 along a third direction z; the second shaping member 132 is movably connected to the fixed mounting platform 110 and can move relative to the holding mechanism 120 along a second direction y. The situation of the two is similar to that of the shaping mechanism 130, and will not be described in detail in the embodiments of this application.

[0048] The first shaping component 131 and the second shaping component 132 may have the same or different structures. For example, both may be small pressure head modules, flat pressure blocks or contouring molds, etc., and adopt symmetrical shaping to flatten the connecting component 210 from the top and bottom or left and right at the same time. For another example, the first shaping component 131 is the main pressure head with a buffer or pressure sensor for main flattening, and the second shaping component 132 is a side push block or positioning block for positioning or auxiliary force application.

[0049] The first shaping member 131 is disposed on one side of the holding mechanism 120 along the third direction z. Specifically, when the holding mechanism 120 holds the battery body 230, it is disposed on the side of the connector 210 away from the battery body 230 along the third direction z. The second shaping member 132 is disposed on one side of the holding mechanism 120 along the second direction y. Specifically, when the holding mechanism 120 holds the battery body 230, it is disposed on the side of the battery body 230 away from the extension direction of the holding mechanism 120 along the second direction y.

[0050] If the first shaping component 131 moves along the third direction z to the second preset position, it indicates that the current position of the first shaping component 131 can abut against the side of the connector 210 away from the battery body 230; if the second shaping component 132 moves along the second direction y to the third preset position, it indicates that the current position of the second shaping component 132 can abut against the side of the connector 210 facing the battery body 230. When both of the above positional relationships are satisfied at the same time, it indicates that the shaping mechanism 130 has moved to the first preset position. At this time, the first shaping component 131 and the second shaping component 132 use a flattening shaping method to shape the connector 210, causing the connector 210 to undergo plastic deformation to achieve the target size and shape.

[0051] Furthermore, the first shaping member 131 can also move relative to the holding mechanism 120 along the second direction y to fine-tune the position of the first shaping member 131 so that its pressure head precisely abuts against one side of the connector 210; and / or, the second shaping member 132 can also move relative to the holding mechanism 120 along the third direction z to fine-tune the position of the second shaping member 132 so that its pressure head precisely abuts against the other side of the connector 210.

[0052] like Figure 2 As shown, stress concentration is particularly pronounced in certain areas of connector 210, such as the bent portion 211 of connector 210. These stress concentration areas often exhibit creases and indentations, increasing the risk of electrical connection failure. Therefore, local reshaping is performed on these stress concentration areas to ensure a more uniform stress distribution.

[0053] Optionally, taking the partial shaping of the bent portion 211 as an example, such as... Figure 5 and Figure 6 As shown, the first shaping member 131 has a first shaping part 1311 and a second shaping part 1312 at one end facing the second shaping member 132; the second shaping member 132 has a third shaping part 1321 and a fourth shaping part 1322 at one end along the second direction y, and along the first direction x, the third shaping part 1321 is correspondingly arranged with the first shaping part 1311, and the fourth shaping part 1322 is correspondingly arranged with the second shaping part 1312.

[0054] In the embodiments of this application, the beneficial effect is that by using multiple shaping parts that are correspondingly provided, the stress concentration area of ​​the connector is locally shaped, so that the stress in the stress concentration area is evenly distributed.

[0055] Specifically, the corresponding setting means that when the shaping mechanism 130 moves to the first preset position in the first direction x, the third shaping part 1321 and the first shaping part 1311 are facing each other in space, and the fourth shaping part 1322 and the second shaping part 1312 are facing each other in space.

[0056] like Figures 3 to 6 As shown, if the first shaping member 131 moves along the third direction z to the second preset position, the first shaping part 1311 and the second shaping part 1312 can abut against the side of the connector 210 away from the battery body 230; if the second shaping member 132 moves along the second direction y to the third preset position, the third shaping part 1321 and the fourth shaping part 1322 can abut against the side of the connector 210 facing the battery body 230. When the above two positional relationships are satisfied simultaneously, the first shaping part 1311 and the third shaping part 1321 perform partial shaping on one bent part 211 by flattening shaping, and the second shaping part 1312 and the fourth shaping part 1322 perform partial shaping on the other bent part 211 by flattening shaping.

[0057] Furthermore, the first shaping part 1311, the second shaping part 1312, the third shaping part 1321 and the fourth shaping part 1322 can also perform local shaping on other stress concentration areas of the connector 210.

[0058] Furthermore, at least one fifth shaping part is provided between the first shaping part 1311 and the second shaping part 1312, and at least one sixth shaping part is provided between the third shaping part 1321 and the fourth shaping part 1322. Each sixth shaping part is provided in correspondence with a fifth shaping part. The fifth shaping part and the sixth shaping part use a flattening shaping method to locally shape other stress concentration areas of the connector 210.

[0059] Furthermore, multiple shaping parts of the same shaping component can be integrally formed, that is, two adjacent shaping parts are interconnected along the first direction x; multiple shaping parts of the same shaping component can also be separately formed, that is, there is a gap between two adjacent shaping parts along the first direction x.

[0060] Stress concentration occurs at the junction of the bent portion 211 and the adjacent area, which can easily lead to cracking or fatigue failure. Furthermore, conventional forming methods cannot accurately control the shape of the local fillet. Therefore, when forming the bent portion 211 locally, a rounded chamfer needs to be machined at the bent portion 211.

[0061] Optionally, such as Figure 5 and Figure 6 As shown, along the third direction z, the third shaping part 1321 has a first end face 132a at one end facing the first shaping part 1311, the fourth shaping part 1322 has a second end face 132b at one end facing the second shaping part 1312, and the two ends of the third shaping part 1321 and the fourth shaping part 1322 that are opposite to each other have a third end face 132c; a first arc transition surface 132d is provided at the junction of the first end face 132a and the third end face 132c, and / or a second arc transition surface 132e is provided at the junction of the second end face 132b and the third end face 132c.

[0062] In the embodiments of this application, the beneficial effect is that the rounded transition surfaces provided on the third and fourth shaping parts are used to process rounded corners at the bending part, so that the stress at the junction of the bending part and the adjacent area is evenly distributed.

[0063] Specifically, along the third direction z, the third shaping part 1321 faces one end of the first shaping part 1311, that is, the end of the third shaping part 1321 that can abut against the connector 210, and has a first end face 132a. The end face of the first shaping part 1311 that abuts against the connector 210 and the first end face 132a together perform partial shaping on the bent part 211; the fourth shaping part 1322 faces one end of the second shaping part 1312, that is, the fourth shaping part 1322 that can abut against the connector 210, and has a second end face 132b. The end face of the fourth shaping part 1322 that abuts against the connector 210 and the second end face 132b together perform partial shaping on the bent part 211.

[0064] The third shaping part 1321 and the fourth shaping part 1322 are separated from each other by a third end face 132c. The third end face 132c serves as a structural boundary or installation positioning reference for positioning, avoidance or expansion of functions.

[0065] At the junction of the first end face 132a and the third end face 132c, i.e., at the corner where the shaped surface turns into the structural boundary, a first arc transition surface 132d is provided; at the junction of the second end face 132b and the third end face 132c, a second arc transition surface 132e is provided. The first arc transition surface 132d and the second arc transition surface 132e are usually rounded corners (R-corners), and the radius can be set according to the process requirements of the bending part 211. They are used to process rounded corners at the bending part 211 so that the stress at the junction of the bending part 211 and the adjacent area is evenly distributed.

[0066] Furthermore, the junctions between the other outer surfaces of the third shaping part 1321 are also provided with arc transition surfaces to facilitate the entry or exit of the third shaping part 1321 into or out of the area enclosed between the connector 210 and the battery body 230. The radius of the arc transition surface can be set according to process requirements. The junctions between the other outer surfaces of the fourth shaping part 1322 are also provided with arc transition surfaces, similar to the third shaping part 1321. The embodiments of this application will not be described in detail.

[0067] The headphone jack has a receiving cavity, within which the battery is housed. Due to the limitations of the device's construction, the shape of the receiving cavity is generally irregular. In some cases, the two battery bodies 230 need to be arranged in an alternating manner to make room for the output component 220. For example... Figure 1 As shown, this staggered arrangement structure gives the connector 210 a first connecting segment 210a and a second connecting segment 210b. The first connecting segment 210a protrudes to the third direction z relative to the second connecting segment 210b, which increases the difficulty of shaping.

[0068] Optionally, such as Figure 5 and Figure 6 As shown, along the third direction z, the first shaping part 1311 protrudes toward the second shaping part 132 relative to the second shaping part 1312.

[0069] In the embodiments of this application, the beneficial effect is that the step-like or staggered structure between the shaping parts realizes the protrusion of the first connecting segment relative to the second connecting segment in the connector.

[0070] Specifically, the first shaping part 1311 and the second shaping part 1312 have a height difference in the third direction z, forming a stepped or staggered structure, so that the first shaping part 1311 is closer to the second shaping part 132 in the third direction z than the second shaping part 1312.

[0071] Meanwhile, the third shaping part 1321 and the fourth shaping part 1322 also have a height difference in the third direction z, forming a stepped or staggered structure, and the height difference between the third shaping part 1321 and the fourth shaping part 1322 in the third direction z is equal to the height difference between the first shaping part 1311 and the second shaping part 1312 in the third direction z. It can be understood that the height difference between two shaping parts of the same shaping component in the third direction z refers to the height difference between the end faces on the same side in the third direction z. For example, for the first shaping part 1311 and the second shaping part 1312, the height difference between them in the third direction z is equal to the height difference between the first end face 132a and the second end face 132b.

[0072] Optionally, such as Figure 8 and Figure 9As shown, the battery processing equipment further includes: a first moving module 141 and a second moving module 142; the first moving module 141 is movably connected to the fixed mounting platform 110, and the first shaping part 131 is fixedly connected to the first moving module 141. The first moving module 141 is used to drive the first shaping part 131 to move relative to the holding mechanism 120 along a third direction z; the second moving module 142 is movably connected to the fixed mounting platform 110, and the second shaping part 132 is fixedly connected to the second moving module 142. The second moving module 142 is used to drive the second shaping part 132 to move relative to the holding mechanism 120 along a second direction y.

[0073] In the embodiments of this application, the beneficial effects are as follows: the first moving module and the second moving module drive the first shaping component and the second shaping component independently, respectively, and the position control of the first shaping component and the second shaping component is realized through the coordinated control between the first moving module and the second moving module.

[0074] Specifically, the first moving module 141 is typically a linear module, which may include a linear guide and slider structure, a ball screw drive structure, or a cylinder / electric cylinder actuation structure, etc. Figure 8 Taking the cylinder-driven structure shown as an example, the first moving module 141 specifically includes a cylinder body, a cylinder piston rod, and a mounting plate. The cylinder body is fixedly connected to the fixed mounting platform 110 via a mounting plate, and the first shaping component 131 is fixedly connected to the cylinder piston rod via another mounting plate. The cylinder piston rod can move relative to the cylinder body along a third direction z. Through the above structure, the first moving module 141 can drive the first shaping component 131 to move relative to the holding mechanism 120 along a third direction z.

[0075] The second moving module 142 is used to drive the second shaping part 132 to move relative to the holding mechanism 120 along the second direction y. The second moving module 142 is similar to the first moving module 141, and will not be described in detail in the embodiments of this application.

[0076] Although the first moving module 141 and the second moving module 142 are independent modules, they can achieve synchronous operation under coordinated control, thereby achieving the shaping of the connector 210.

[0077] Furthermore, through two independent linear modules, the first moving module 141 drives the first shaping component 131 to move relative to the holding mechanism 120 along the second direction y and the third direction z, and the second moving module 142 drives the second shaping component 132 to move relative to the holding mechanism 120 along the second direction y and the third direction z.

[0078] Optionally, such as Figure 3 and Figure 10As shown, the first holding sub-mechanism 121 and the second holding sub-mechanism 122 include: a swing arm 1231 and a holding member 1232; the swing arm 1231 of the first holding sub-mechanism 121 and the swing arm 1231 of the second holding sub-mechanism 122 are spaced apart along the first direction x, the swing arm 1231 is movably connected to the fixed mounting platform 110 and can rotate relative to the fixed mounting platform 110 around the second direction y; the holding member 1232 is fixedly connected to the swing arm 1231 and is used to hold the battery body and drive the battery body to flip.

[0079] In the embodiments of this application, the beneficial effect is that the functional decoupling design of the swing arm and the holding component reduces the optimization difficulty and maintenance cost of the holding sub-mechanism.

[0080] Specifically, the two swing arms 1231 are spaced apart along the first direction x, similar to the first holding sub-mechanism 121 and the second holding sub-mechanism 122 being spaced apart along the first direction x; the swing arms 1231 are movably connected to the fixed mounting platform 110 and can rotate relative to the fixed mounting platform 110 about the second direction y, similar to the first holding sub-mechanism 121 being movably connected to the fixed mounting platform 110; the holding member 1232 is used to hold the battery body and drive the battery body to rotate, similar to the first holding sub-mechanism 121 holding the battery body 230 and driving the battery body 230 to rotate. The embodiments of this application will not elaborate further on the above.

[0081] The retaining component 1232 is mainly responsible for retaining the battery body 230, while the swing arm 1231 acts as the output shaft of the revolute joint, primarily responsible for driving the retaining component 1232 and thus the battery body 230 to rotate relative to the fixed mounting platform 110 around the second direction y. Through this functional decoupling design, modular division of labor for the multi-degree-of-freedom motion of the battery body 230 is achieved, facilitating independent optimization and maintenance.

[0082] When the retaining member 1232 holds the battery body 230 by clamping or clamping, scratches, indentations, or deformation may easily appear on the surface of the battery body 230. Therefore, the retaining member 1232 uses an adsorption method to hold the battery body 230.

[0083] Optionally, such as Figure 10 As shown, the retainer 1232 is provided with an adsorption hole 123a, which is used to communicate with the negative pressure mechanism.

[0084] In the embodiments of this application, the beneficial effect is that by using adsorption to hold the battery body, scratches, indentations and deformations on the surface of the battery body are avoided.

[0085] Specifically, an adsorption hole 123a (i.e. a small hole leading to the internal negative pressure channel) is provided on the surface of the retainer 1232 that contacts the battery body 230. These adsorption holes 123a are connected to a negative pressure mechanism such as a vacuum generator or a vacuum pump through an external pipeline or an internal flow channel.

[0086] The adsorption pore 123a is typically a small circular pore, the diameter of which can be designed according to the battery size and surface characteristics. The adsorption pore 123a can be arranged as a single pore, a multi-pore array, or a ring distribution to ensure uniform adsorption force; the opening of the adsorption pore 123a can be chamfered or countersunk to prevent scratching the surface of the battery body 230.

[0087] The retainer 1232 has a built-in air channel, which can be a straight hole, an L-shaped hole, or a channel structure integrated inside the retainer 1232. The built-in air channel is connected below the adsorption hole 123a and flows to one or more vacuum ports.

[0088] The vacuum interface connects to the external negative pressure mechanism via an external pipe mounted on the outer surface of the swing arm 1231 or a built-in flow channel inside the swing arm 1231. The negative pressure mechanism can be integrated into the battery processing equipment or deployed independently relative to the battery processing equipment. The negative pressure mechanism typically includes a vacuum generator (or vacuum pump), a pressure sensor, and a solenoid valve. The vacuum generator generates negative pressure and forms an adsorption force on the surface of the retainer 1232 through the adsorption hole 123a; the pressure sensor detects the magnitude of the adsorption force so that the solenoid valve adjusts the magnitude of the adsorption force according to the weight of the battery or the surface material to prevent retention failure.

[0089] When the battery is transported to the holding member 1232 by a multi-degree-of-freedom conveying device such as a robotic arm, the holding member 1232 can directly hold the battery. When the battery is transported to the holding member 1232 by a single-degree-of-freedom conveying device such as a conveyor belt, the holding member 1232 needs to move to a fourth preset position above the conveyor belt before holding the battery. Therefore, the holding member 1232 needs to be able to move relative to the holding mechanism 120 to the fourth preset position.

[0090] Optionally, such as Figure 3 , Figure 10 and Figure 11 As shown, the battery processing equipment also includes: a third moving module 143 and a connecting plate 144; the third moving module 143 is movably connected to the fixed mounting platform 110; the connecting plate 144 is fixedly connected to the third moving module 143, and the swing arm 1231 is rotatably connected to the connecting plate 144. The third moving module 143 is used to drive the connecting plate 144 to move along the second direction y and the third direction z.

[0091] In this embodiment of the application, the beneficial effect is that the position control of the holding member is realized by driving the swing arm through the third moving module and then driving the holding member.

[0092] The connecting plate 144 is equivalent to the mounting plate of the first moving module 141. The third moving module 143 is used to drive the swing arm 1231 to move relative to the fixed mounting platform 110 along the second direction y and the third direction z. The third moving module 143 is similar to the first moving module 141, and will not be described in detail in this embodiment.

[0093] Inaccurate control of the swing arm rotation may cause the verticality deviation of the battery body 230 to exceed the standard range. During battery and battery holder assembly, the gap control between the battery and battery holder is unstable due to the weak rigidity of the battery holder, affecting the overall sealing and structural stability. Therefore, a rotation module is used to control the swing arm to rotate relative to the fixed mounting platform 110 in the second direction y to ensure that the battery's verticality deviation does not exceed the standard range.

[0094] Optionally, such as Figure 3 and Figure 10 As shown, the battery processing equipment also includes: a rotating module 145; the rotating module 145 is movably connected to the connecting plate 144, and the swing arm 1231 is drivenly connected to the rotating module 145. The rotating module 145 is used to drive the swing arm 1231 to rotate relative to the fixed mounting platform 110 around the second direction y.

[0095] In this embodiment, the beneficial effect is that by driving the swing arm through the rotating module, precise control of the swing arm is achieved, ensuring the verticality deviation of the battery.

[0096] Specifically, the swing arm 1231 is no longer directly connected to the fixed mounting platform 110 for rotation, but is fixedly connected to the rotation module 145. The rotation module 145 is an independent functional module used to drive the swing arm 1231 to rotate precisely around the second direction y, thereby driving the retainer 1232 and the battery body 230 to complete the flipping action.

[0097] The rotating module 145 may encompass a servo motor and reducer drive structure, or a pneumatic / hydraulic rotary cylinder structure, etc. Figure 10 Taking the motor and reducer drive structure shown as an example, the rotating module 145 specifically includes a drive motor, a reducer, and an output shaft. The drive motor and / or reducer are fixedly connected to the connecting plate 144, and the swing arm 1231 is drivenly connected to the output shaft, or is integrally formed with the output shaft. With the above structure, the rotating module 145 can drive the swing arm 1231 to rotate relative to the fixed mounting platform 110 around the second direction y.

[0098] Furthermore, two sets of rotating sub-modules are provided, each including a drive motor, a reducer, and an output shaft, and each set of rotating sub-modules is used to drive one swing arm. Although the two sets of rotating sub-modules are independent modules, they can achieve synchronous movement under coordinated control, thereby driving the swing arms 1231 to rotate.

[0099] Furthermore, since the distance between the two swing arms 1231 is relatively short, the output shaft and the swing arms 1231 cannot be arranged coaxially. Based on this, the rotating sub-module also includes a transmission mechanism, through which the output shaft drives the swing arms 1231 to rotate. The transmission mechanism can be a gear transmission mechanism, a belt transmission mechanism, a chain transmission structure, or other mechanisms.

[0100] Furthermore, to prevent the battery body from over-rotating, the rotating sub-module also includes a limiting mechanism to restrict the rotation angle of the output shaft. For example, the rotation angle of the output shaft is limited to 90° from the starting point. After both output shafts rotate 90°, the battery body 230 is rotated 180°.

[0101] This application also provides a control method for battery processing equipment. The control method for battery processing equipment is used to control the battery processing equipment in the above embodiments, and the method includes: S101. When the conveyor belt transports the battery to the designated position, the third moving module, with the help of the rotating module and the swing arm, drives the holding member to move from the initial position to the fourth preset position.

[0102] S102, The holding component holds the battery body of the battery by vacuum adsorption using a negative pressure mechanism.

[0103] S103, the third moving module uses the rotating module and the swing arm to move the holding member from the fourth preset position to the initial position.

[0104] S104, the rotating module uses a swing arm and a retaining component to rotate the battery body until the battery body is rotated 180°. For example... Figure 12 As shown, the relative positions of the front swing arm and the retaining member of the flipped battery body are illustrated, as well as the relative positions of the rear swing arm and the retaining member of the flipped battery body. During the flipping process of the battery body, the battery connectors are bent synchronously with the flipping of the battery body.

[0105] S105, the first rotating module drives the first shaping part to move from the initial position to the second preset position, and the second rotating module drives the second shaping part to move from the initial position to the third preset position.

[0106] S106. The first rotating module shapes the connector by passing through the first and second shaping parts of the first shaping part, and the second rotating module shapes the connector by passing through the third and fourth shaping parts of the second shaping part.

[0107] S107. The first rotating module drives the first shaping part to move from the second preset position to the initial position, and the second rotating module drives the second shaping part to move from the third preset position to the initial position.

[0108] S108, the third moving module uses the rotating module and the swing arm to move the holding part from the initial position to the initial position.

[0109] S109, Battery release via retainer.

[0110] S110, the third moving module, with the help of the rotating module and the swing arm, moves the holding component from the fourth preset position to the initial position. This completes the entire process of holding, shaping, and releasing the battery.
