Description

Technical Field

[0001] This utility model relates to the field of battery clamp technology, specifically to a battery clamp and a spraying device. Background Technology

[0002] To ensure battery safety, waterproofing, and corrosion resistance, a coating needs to be sprayed onto the battery surface to form a protective layer. In related technologies, the spraying process is generally done manually. A conveyor line moves a pallet to the spraying location, and workers apply insulating varnish to the battery's outer surface. During spraying, the varnish disperses into the air, and prolonged exposure can lead to workers inhaling excessive amounts of this varnish, causing health problems. Furthermore, the spraying efficiency is low. Utility Model Content

[0055] Detailed Implementation

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0057] To ensure battery safety, waterproofing, and corrosion resistance, a coating needs to be sprayed onto the battery surface to form a protective layer. In related technologies, the spraying process is generally done manually. A conveyor line moves a pallet to the spraying location, and workers apply insulating varnish to the battery's outer surface. During spraying, the varnish disperses into the air, and prolonged exposure can lead to workers inhaling excessive amounts of this varnish, causing health problems. Furthermore, the spraying efficiency is low.

[0058] In view of this, the present invention proposes a battery clamp 100. Figures 1 to 10 This is a schematic diagram of one embodiment of the battery clamp 100 provided by the present invention. The battery clamp 100 provided by the present invention has a simple structure and can clamp and fix two batteries 400 at one time, with high working efficiency. The battery clamp 100 will be described in detail below with reference to the main drawings.

[0059] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a battery clamp 100 configured to hold two batteries 400. The battery clamp 100 includes a base 101, a plurality of grippers 102, and a drive mechanism 103. The plurality of grippers 102 are mounted on the base 101. The drive mechanism 103 is mounted on the base 101 and drives at least one gripper 102. In a first state, a first portion of the grippers 104 is configured to jointly hold the two batteries 400 to expose two adjacent sides of each battery 400. In a second state, a second portion of the grippers 105 is configured to hold one of the batteries 400, and a third portion of the grippers 102 is configured to hold the other battery 400 to expose two terminal surfaces of each battery 400.

[0060] In the technical solution of this utility model, multiple grippers 102 are used to clamp and fix two batteries 400. The driving mechanism 103 drives and connects at least one gripper 102, so that the distance between the multiple grippers 102 can be adjusted, thereby enabling the multiple grippers 102 to clamp and fix batteries 400 of different sizes and models, and improving the versatility of the battery clamp 100. Meanwhile, the battery clamp 100 provided in this application can coat multiple sides of the battery 400. In a first state, the first portion of the clamps 104 among the multiple clamps 102 is configured to jointly clamp two batteries 400, exposing two adjacent sides of each battery 400. In a second state, the second portion of the clamps 105 among the multiple clamps 102 is configured to clamp one battery 400, and the third portion of the clamps 133 among the multiple clamps 102 is configured to clamp the other battery 400, exposing two terminal surfaces of each battery 400. By using different states of the battery clamp 100 to expose different sides and terminal surfaces of the battery 400, the surface of the battery 400 can be completely coated, resulting in high manufacturing efficiency. Using the battery clamp 100 to hold and fix the battery 400 eliminates the need for operator intervention, reducing harm to the human body and improving safety.

[0061] The specific type of battery 400 is not limited. It can be a long blade battery, a short blade battery, a rectangular battery, or a cylindrical battery. The appropriate type can be selected based on the actual situation. The following will use a short blade battery as an example to illustrate the specific structure of the battery clamp 100.

[0062] In some embodiments, the battery 400 has multiple sides and two terminal surfaces. The multiple sides include two large sides and two small sides arranged opposite each other. In a first state, the first portion of the gripper 104 of the multiple grippers clamps onto the two small sides of the battery 400, exposing the two terminal surfaces of the battery 400, allowing paint to be sprayed onto the terminal surfaces of the battery 400. Of course, the first portion of the gripper 104 can also clamp onto the two large sides of the battery 400, depending on the actual situation. Compared to the gripping method where the first portion of the gripper 104 clamps onto the two large sides, the method where the first portion of the gripper 104 clamps onto the two small sides is better, providing more stable clamping, more even force distribution on the battery 400, and less space occupation.

[0063] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 3The multiple grippers include a first gripper 106, a second gripper 107, a third gripper 108, and a fourth gripper 109. The first gripper 106 and the second gripper 107 are arranged opposite to each other. The first gripper 106 is fixedly mounted on the base 101. The second gripper 107 is connected to the drive mechanism 103 and is driven by the drive mechanism 103 to move closer to or away from the first gripper 106. The third gripper 108 and the fourth gripper 109 are located between the first gripper 106 and the second gripper 107. The third gripper 108 is located closer to the first gripper 106, and the fourth gripper 109 is located closer to the second gripper 107. The third gripper 108 is connected to the drive mechanism 103 and is driven by the drive mechanism 103 to move closer to or away from the first gripper 106. The fourth gripper 109 is fixedly connected to the base 101.

[0064] Furthermore, in the first state, the first gripper 104 includes a first gripper 106 and a second gripper 107. The second gripper 107 moves closer to the first gripper 106, thereby cooperating with the first gripper 106 to clamp the two batteries 400. In the second state, the second gripper 105 includes a first gripper 106 and a third gripper 108, and the third gripper 133 includes a second gripper 107 and a fourth gripper 109. The drive mechanism 103 drives the second gripper 107 to move closer to the fourth gripper 109, and simultaneously drives the third gripper 108 to move towards the first gripper 106, thereby clamping and fixing one battery 400 between the first gripper 106 and the third gripper 108, and clamping and fixing the other battery 400 between the second gripper 107 and the fourth gripper 109.

[0065] Please see 1 and Figure 4In some embodiments, the battery clamp 100 further includes a first support column 134, a second support column 118, a third support column 110, and a fourth support column 111. The first support column 134 and the fourth support column 111 are fixedly connected to the base 101, while the second support column 118 and the third support column 110 are mounted on the drive mechanism 103 and driven by the drive mechanism 103. A first gripper 106 is detachably mounted on the first support column 134, a second gripper 107 is detachably mounted on the second support column 118, a third gripper 108 is detachably mounted on the third support column 110, and a fourth gripper 109 is detachably mounted on the fourth support column 111. In the first state, since the first gripper 106 needs to cooperate with the second gripper 107 to clamp two batteries 400, the third gripper 108 needs to be disassembled from the third support post 110, and the fourth gripper 109 needs to be disassembled from the fourth support post 111, thereby avoiding interference between the third gripper 108 and the fourth gripper 109 and the two batteries 400. In the second state, the drive mechanism 103 drives the third support post 110 to move, causing the third gripper 108 to move closer to the first gripper 106. At the same time, the drive mechanism 103 also drives the second support post 118, causing the second gripper 107 to move closer to the fourth gripper 109. The first gripper 106 and the third gripper 108 cooperate to clamp and fix one battery 400, and the second gripper 107 and the fourth gripper 109 cooperate to clamp and fix the other battery 400.

[0066] In this embodiment, please refer to Figure 6 The first gripper 106 is detachably connected to the first support post 134. This configuration allows the first gripper 106 to accommodate batteries 400 of different models and sizes. When the battery 400 is large, the first gripper 106 can be removed and replaced with a larger-sized first gripper 106. When the battery 400 is small, the larger-sized first gripper 106 can be removed and replaced with a smaller-sized first gripper 106. This improves the versatility of the battery clamp 100.

[0067] Optionally, the first support column 134 is provided with a quick-release structure, which cooperates with the first gripper 106 to achieve quick disassembly and replacement. Specifically, the first support column 134 has a first slot 125, and the first gripper 106 is provided with a first receiving platform 124, which engages with the first slot 125. The first support column 134 is also provided with a first buckle 126, which is movably installed on the first support column 134 and located on the side of the first support column 134 away from the second support column 118. When the first receiving platform 124 of the first gripper 106 engages with the first slot 125, the first buckle 126 rotates along its axial direction, thereby abutting against the top of the first receiving platform 124, thus fixing the first gripper 106 on the first support column 134. When it is necessary to disassemble the first gripper 106, rotate the first latch 126 to separate it from the first receiving platform 124, allowing the first gripper 106 to be removed and replaced. This design simplifies the disassembly process, improves installation efficiency, and thus increases production capacity.

[0068] Furthermore, a buffer pad 127 is provided on the side of the first gripper 106 near the battery 400. The buffer pad 127 can protect the battery 400 and prevent the first gripper 106 from scratching or damaging the surface of the battery 400 when clamping and fixing it. Specifically, the material of the buffer pad 127 is not limited; it can be a rubber pad, a foam pad, etc., and can be selected according to the actual situation.

[0069] The connection method between the second gripper 107 and the second support post 118 is the same as the connection method between the first gripper 106 and the first support post 134. The connection method between the second gripper 107 and the second support post 118 can be referred to the connection method between the first gripper 106 and the first support post 134, and will not be described in detail here.

[0070] In some embodiments, the connection method between the fourth gripper 109 and the fourth support post 111 is the same as the connection method between the first gripper 106 and the first support post 134. The connection method between the fourth gripper 109 and the fourth support post 111 can be referred to the connection method between the first gripper 106 and the first support post 134, and will not be described in detail here.

[0071] In some embodiments, the third gripper 108 is detachably connected to the third support post 110. Specifically, please refer to [link to relevant documentation]. Figure 7 and Figure 8The third support column 110 has two first snap-fit ​​posts 128 on the side facing the first support column 134. The two first snap-fit ​​posts 128 are spaced apart. The third gripper 108 has a first snap-fit ​​hole 136 corresponding to the two first snap-fit ​​posts 128. The third support column 110 also has a snap-fit ​​block 130, which is movably installed on the third support column 110. The snap-fit ​​block 130 includes a first part 131 and a second part 135 connected together. The second part 135 is bent and connected to the side of the first part 131 facing the first support column 134. The first part 131 is movably disposed on the third support column 110. Specifically, a first groove is formed on the third support column 110. The first part 131 is movably disposed in the first groove. An elastic element is provided between the first part 131 and the bottom of the first groove. The second part 135 has a second snap-fit ​​post 129 on the side away from the base 101. The third gripper 108 has a second snap-fit ​​hole 137 corresponding to the second snap-fit ​​post 129. More specifically, during actual installation, the snap-fit ​​block 130 is pressed towards the base 101 (i.e., the snap-fit ​​block 130 presses against the elastic element). At this time, the second snap-fit ​​post 129 moves away from the first snap-fit ​​post 128, and the first snap-fit ​​hole 136 on the third clamp 108 engages with the first snap-fit ​​post 128, so that the third clamp 108 and the third support post 110 are pre-fixed. After the pre-fixing is completed, the snap-fit ​​block 130 is released, and the snap-fit ​​block 130 begins to rebound under the elastic restoring force of the elastic element. The second snap-fit ​​post 129 snaps into the second snap-fit ​​hole 137, thereby fixing the third clamp 108 on the third support post 110. When it is necessary to disassemble the third gripper 108, press the locking block 130 so that the locking block 130 squeezes the elastic element, the second locking post 129 disengages from the second locking hole 137, and then the third gripper 108 is separated from the first locking post 128, thereby separating the third gripper 108 from the third support.

[0072] Furthermore, in some embodiments, the elastic element is a spring.

[0073] Specifically, in the first state, the third gripper 108 separates from the third support post 110, and the fourth gripper 109 separates from the fourth support post 111. The two batteries 400 are placed side by side between the first gripper 106 and the second gripper 107. The drive mechanism 103 drives the second gripper 107 to move closer to the first gripper 106. The second gripper 107 and the first gripper 106 cooperate to clamp and fix the two batteries 400, exposing the terminal surfaces of the two batteries 400, thereby allowing the two terminal surfaces to be sprayed. After the spraying is completed, the drive mechanism 103 drives the second gripper 107 to move away from the first gripper 106, causing the first gripper 106 and the second gripper 107 to release their grip on the two batteries 400, facilitating the next operation.

[0074] In the second state, the third gripper 108 is fixed to the third support post 110, and the fourth gripper 109 is fixed to the fourth support post 111. Two batteries 400 are placed between the first gripper 106 and the third gripper 108, and between the second gripper 107 and the fourth gripper 109, respectively. The drive mechanism 103 drives the second gripper 107 to move closer to the fourth gripper 109, and simultaneously drives the third gripper 108 to move closer to the first gripper 106. The first gripper 106 and the third gripper 108 cooperate to clamp and fix one battery 400, while the second gripper 107 and the fourth gripper 109 clamp and fix the other. An additional battery 400 is applied, exposing two adjacent sides of each battery 400. After the coating is completed, the drive mechanism 103 drives the second gripper 107 away from the fourth gripper 109, and simultaneously drives the third gripper 108 away from the first gripper 106, flipping the battery 400 over so that the other two uncoated sides of each battery 400 are exposed. The drive mechanism 103 then drives the second gripper 107 closer to the fourth gripper 109, and simultaneously drives the third gripper 108 closer to the first gripper 106, thus clamping and fixing the two batteries 400 again.

[0075] It should be noted that the specific type of the drive mechanism 103 is not limited; it can be selected according to the actual situation. In some embodiments, please refer to... Figure 3 and Figure 4 The drive mechanism 103 includes a drive member 112, a transmission member 113, and a connecting member 114. The drive member 112 is mounted on the base 101 and provides kinetic energy to drive the transmission member 113. The transmission member 113 is kinetically connected to the drive member 112 and is driven by the drive member 112. The connecting member 114 is connected to the transmission member 113 and is driven by the transmission member 113. The second gripper 107 and the third gripper 108 are mounted on the connecting member 114 and move synchronously in a second state. Specifically, in actual operation, the drive member 112 operates, driving the transmission member 113 to move. The connecting member 114 is mounted on the transmission member 113 and moves with the transmission member 113, thereby driving the first gripper 106 and the third gripper 108 to move synchronously. This arrangement allows one drive member 112 to drive two components simultaneously, saving parts and improving the compactness of the structure.

[0076] It should be noted that the specific types of the driving component 112 and the transmission component 113 are not limited, and can be selected according to the actual situation. For example, when the driving component 112 is a linear motor, the transmission component 113 is a transmission shaft, and the linear motor is connected to the transmission shaft to drive linear motion. When the driving component 112 is a servo motor, the transmission component 113 can be a lead screw 115 and nut 116 mechanism, and the transmission component 113 is used to convert the rotational motion of the servo motor into linear motion.

[0077] In this embodiment, please refer to Figure 3 and Figure 4 The driving component 112 is a servo motor, and the transmission component 113 is a lead screw 115 and nut 116 mechanism. Specifically, the transmission component 113 includes a lead screw 115, a nut 116, and a stop bar 117. The lead screw 115 is connected to the servo motor; the nut 116 is threadedly connected to the lead screw 115, and a connecting member 114 is disposed on the nut 116, moving together with the nut 116; more specifically, the servo motor drives the lead screw 115 to rotate, the lead screw 115 cooperates with the nut 116, and the nut 116 moves along the length of the lead screw 115, thereby driving the connecting member 114 to move.

[0078] It should be noted that the battery clamp 100 provided in this application is mainly used to clamp and fix the battery 400, thereby facilitating the spraying of paint onto the surface of the battery 400. During the spraying process, the battery clamp 100 moves with the battery 400, and paint or other substances can easily splash onto the lead screw 115, causing the lead screw 115 and nut 116 to jam, affecting normal production. To avoid the above situation, please refer to... Figure 3 and Figure 4 The transmission component 113 also includes a stop bar 117, which is located on the side of the nut 116 away from the lead screw 115 and is fixedly connected to the base 101. Furthermore, the connector 114 needs to be connected to the nut 116 and move together with the nut 116. In order to avoid interference between the stop bar 117 and the connector 114, a through hole is formed on the connector 114, through which the stop bar 117 extends. Both ends of the stop bar 117 are fixedly connected to both ends of the base 101. This arrangement allows the stop bar 117 to both shield the paint and prevent the paint from splashing onto the lead screw 115 and causing the lead screw 115 to jam, and also avoid interference with the connector 114.

[0079] Furthermore, the connector 114 includes a second support post 118, a third support post 110, and a connecting strip 119. The connecting strip 119 is connected to the nut 116. The second support post 118 and the third support post 110 are disposed on the connecting strip 119. The second support post 118 is connected to the third support post 110 through the connecting strip 119. The connecting strip 119 is used to adjust the relative position between the second support post 118 and the third support post 110. More specifically, the connecting strip 119 is provided with multiple snap-fit ​​holes, and the third support post 110 is provided with snap-fit ​​blocks that cooperate with the multiple snap-fit ​​holes. The snap-fit ​​blocks cooperate with the snap-fit ​​holes at different positions to adjust the distance between the third support post 110 and the first support post 134. This configuration can improve the versatility of the battery clamp 100, enabling the battery clamp 100 to clamp different models of batteries 400. When the battery 400 is large, the larger battery 400 can be clamped by engaging the locking block in the locking hole away from the first gripper 106 and adjusting the distance between the first gripper 106 and the third gripper 108. When the battery 400 is small, the smaller battery 400 can be clamped and fixed by engaging the locking block in the locking hole close to the first gripper 106 and adjusting the distance between the first gripper 106 and the third gripper 108.

[0080] The distance adjustment method between the second jaw 107 and the fourth jaw 109 is the same as the distance adjustment method between the first jaw 106 and the third jaw 108. The distance adjustment method between the second jaw 107 and the fourth jaw 109 can be referred to the distance adjustment method between the first jaw 106 and the third jaw 108, and will not be described in detail here.

[0081] It should be noted that, in order to ensure the stability of the transmission, two connecting bars 119 are provided, located on both sides of the lead screw 115. The two ends of the third support column 110, which are positioned opposite each other along the width direction of the base 101, are respectively connected to the two connecting bars 119. This arrangement can improve the stability of the connection between the transmission component 113 and the connecting component 114.

[0082] In some embodiments, the battery clamp 100 further includes two first reference members 120. The two first reference members 120 are connected to the drive mechanism 103 and are disposed between the first gripper 106 and the second gripper 107. The two first reference members 120 are connected to the drive mechanism 103 and are driven by the first drive mechanism 103. In the first state, the third gripper 108 is separated from the third support post 110, and the fourth gripper 109 is separated from the fourth support post 111. The two first reference members 120 are exposed, and the two batteries 400 are placed between the first gripper 106 and the second gripper 107. The two first reference members 120 are located between the two batteries 400 and are located at the same reference. One battery 400 uses one of the first reference members 120 as a reference, and the other battery 400 uses the other first reference member 120 as a reference. The two batteries 400 are adjusted so that they are located at the same reference.

[0083] Furthermore, to save parts and reduce costs, the two first reference members 120 are driven by the same drive mechanism 103. Specifically, in the first state, the two first reference members 120 are driven by the drive mechanism 103 to move closer to or away from one side of one of the batteries 400, and drive the second gripper 107 to move closer to or away from the first gripper 106. This arrangement allows the drive mechanism 103 to drive both the second gripper 107 and the two first reference members 120, reducing the number of parts used and lowering costs.

[0084] It should be noted that the connection method between the first reference component 120 and the drive mechanism 103 is not limited and can be selected according to the actual situation. In this embodiment, please refer to... Figure 9 and Figure 10 The battery clamp 100 also includes a linkage mechanism, which comprises a first linkage member 122 and a second linkage member 123 that are slidably connected. A first reference member 120 is slidably mounted on the base 101 via the first linkage member 122, and a second gripper 107 is slidably mounted on the base 101 via the second linkage member 123. The sliding direction of the first linkage member 122 is inclined relative to the sliding direction of the first reference member 120 and the sliding direction of the second gripper 107. It should be noted that the inclined design is intended to save space and improve the compactness of the structure.

[0085] In some other embodiments, the battery clamp 100 is provided with a first reference member 120. The driving method and setting method of the first reference member 120 are the same as those of the two reference members, and will not be described in detail here. The battery clamp 100 also includes a second reference member 121, which is located on one side of the base 101. The second reference member 121 and the first reference member 120 are located at the same reference. In the first state, one battery 400 uses the first reference member 120 as a reference, and the other battery 400 uses the second reference member 121 as a reference. The positions of the two batteries 400 are adjusted so that the two batteries 400 are located at the same reference.

[0086] In some embodiments, in the second state, the terminal surfaces of the two batteries 400 are aligned with the first reference member 120 so that the two batteries 400 are located at the same reference.

[0087] Furthermore, the battery clamp 100 also includes a first reference support column 132, which is connected to the drive mechanism 103. A first reference member 120 is detachably connected to the first reference support column 132. When the battery clamp 100 is in the second state, the first reference member 120 can be disassembled to avoid interference with the battery 400. It should be noted that the connection method between the first reference member 120 and the first reference support column 132 is similar to the connection method between the third gripper 108 and the third support column 110, and will not be described in detail here.

[0088] Furthermore, the first reference component 120 is detachably connected to the first reference support column 132. In the first state, after the battery 400 is fixed, the first reference component 120 can be disassembled to prevent paint from being sprayed onto the first reference component 120, causing corrosion to the first reference component 120 and affecting the positioning and reference effect of the first reference component 120.

[0089] This utility model also proposes a spraying device 1000, please refer to [link / reference]. Figures 11 to 13 The spraying equipment 1000 includes the battery clamp 100 described above. The specific structure of the battery clamp 100 is as described in the above embodiments. Since the spraying equipment 1000 adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0090] Furthermore, the spraying equipment 1000 also includes a conveyor belt 200 and a spraying chamber 300. The spraying chamber 300 is located on one side of the conveyor belt 200, and the battery clamp 100 is located on the other side of the conveyor belt 200. Specifically, in this embodiment, the operator fixes the battery 400 to be processed on the battery clamp 100. The battery clamp 100 is conveyed by the conveyor belt into the spraying chamber 300 for spraying. After spraying is completed, the conveyor belt 200 rotates in the opposite direction to convey the battery clamp 100 out. The operator changes the processing surface of the battery 400 and repeats the above steps until all six surfaces of the battery 400 are processed.

[0091] With the conveying direction of the conveyor belt 200 as the first direction and the width direction of the transmission belt as the second direction, the spraying chamber 300 is installed over one end of the transmission belt. The spraying chamber 300 includes two first spraying surfaces 301 arranged opposite each other along the second direction, and a second spraying surface 302 located above the transmission belt and spaced apart from it. When the spraying chamber 300 is in operation, the control system can control the two first spraying surfaces 301 and the second spraying surface 302 to work simultaneously; it can also control the two first spraying surfaces 301 to work individually while the second spraying surface 302 remains inactive; it can also control one of the first spraying surfaces 301 and the second spraying surface 302 to work while the other first spraying surface 301 remains inactive; or it can control the second spraying surface 302 to work while the two first spraying surfaces 301 remain inactive. The appropriate option can be selected based on the actual situation. The control system can be configured according to conventional settings in the field, and will not be elaborated further here.

[0092] Please see Figure 13 The battery 400 includes two terminal surfaces and four side surfaces. The two terminal surfaces are a first terminal surface 401 and a second terminal surface 402. The four side surfaces are a first side surface 403, a second side surface 404, a third side surface 405 and a fourth side surface 406. The first side surface 403 and the second side surface 404 are large side surfaces arranged opposite each other, and the third side surface 405 and the fourth side surface 406 are small side surfaces arranged opposite each other.

[0093] Specifically, please refer to Figure 11First, the first terminal surfaces 401 and 402 of two batteries 400 are sprayed. The battery clamp 100 includes a first clamp 106, a second clamp 107, a third clamp 108, and a fourth clamp 109. One battery 400 is positioned between the first clamp 106 and the third clamp 108, which clamp the third side 405 and the fourth side 406 of the battery 400, exposing the first terminal surfaces 401 and 402. The other battery 400 is positioned between the second clamp 107 and the fourth clamp 109, which clamp the third side 405 and the fourth side 406 of the battery 400, exposing the first terminal surfaces 401 and 402. When installing the two batteries 400, they are positioned with the second reference member 121 as a reference. After the two batteries 400 are fixed, the conveyor belt 200 starts working, driving the battery clamp 100 to move towards the spraying chamber 300. When the battery clamp 100 moves into the spraying chamber 300, the two first spraying surfaces 301 of the spraying chamber 300 work, while the second spraying surface 302 does not work, and the first electrode surfaces 401 and the second electrode surfaces 402 of the two batteries 400 are sprayed.

[0094] After the spraying is completed, the conveyor belt 200 rotates in the reverse direction, causing the battery clamp 100 to move away from the spraying chamber 300. When the battery clamp 100 moves to its initial position, the first gripper 106, the second gripper 107, the third gripper 108, and the fourth gripper 109 release their gripping action on the two batteries 400. Please refer to [link / reference]. Figure 12 The operator disassembles the third gripper 108 and the fourth gripper 109, installs the two first reference parts 120 on the first reference support column 132, and places the two batteries 400 side by side with the two first reference parts 120 and the second reference part 121 as references. The first gripper 106 and the second gripper 107 fix the two batteries 400. At this time, the first side 403 and the third side 405 of the two batteries 400 are exposed. The conveyor belt 200 starts to work, driving the battery clamp 100 to move towards the spraying chamber 300. When the battery clamp 100 moves into the spraying chamber 300, the two first spraying surfaces 301 and the second spraying surface 302 of the spraying chamber 300 work, and the first side 403 and the third side 405 of the two batteries 400 are sprayed.

[0095] After the spraying is completed, the conveyor belt 200 rotates in the reverse direction, driving the battery clamp 100 to move away from the spraying chamber 300. When the battery clamp 100 moves to the initial position, the first gripper 106 and the second gripper 107 loosen, reversing the two batteries 400 so that the second side 404 and the fourth side 406 of the two batteries 400 are exposed. The first gripper 106 and the second gripper 107 fix the two batteries 400. The conveyor belt 200 starts working, driving the battery clamp 100 to move towards the spraying chamber 300. When the battery clamp 100 moves into the spraying chamber 300, the two first spraying surfaces 301 and the second spraying surface 302 of the spraying chamber 300 are working, and the second side 404 and the fourth side 406 of the two batteries 400 are sprayed.

[0096] At this point, the two terminal surfaces and four sides of battery 400 have been coated, and the coating of battery 400 is complete.

[0097] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
