Description

Battery clamps and spraying equipment

[0001] This application claims priority to Chinese Patent Application No. 202520171782.9, filed with the Chinese Patent Office on January 24, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of battery technology, specifically to a battery clamp and a spraying device. Background Technology

[0003] To ensure the safety, water resistance, and corrosion resistance of the battery, a coating needs to be sprayed onto the battery surface to form a protective layer.

[0004] In related technologies, the spraying process is generally carried out manually. The conveyor line moves the pallet to the spraying work area, and the workers apply insulating paint to the outer surface of the battery. During the spraying process, the paint is dispersed in the air. If workers are in the air for a long time, they will inhale too much insulating paint, which will cause certain harm to their health. In addition, the spraying efficiency is low. Invention Overview

[0005] This application aims to solve the technical problems of low safety and low efficiency of manual spraying in related technologies.

[0006] In a first aspect, this application provides a battery clamp configured to hold two batteries, the battery clamp comprising:

[0007] Base;

[0008] Multiple grippers, mounted on the base; and,

[0009] A drive mechanism, mounted on the base, drives at least one gripper.

[0010] In the first state, the first portion of the grippers among the multiple grippers is configured to jointly grip two batteries to expose two adjacent sides of each battery.

[0011] In the second state, the second portion of the multiple grippers is configured to hold one of the batteries, and the third portion of the multiple grippers is configured to hold another battery to expose the two terminal surfaces of each battery.

[0012] Secondly, this application also provides a spraying apparatus. The spraying apparatus includes the aforementioned battery clamp. Beneficial effects

[0013] In the technical solution of this application, multiple grippers are configured to hold and fix two batteries. A drive mechanism drives and connects at least one gripper, allowing the distance between the grippers to be adjusted. This enables the grippers to hold and fix batteries of different sizes and models, improving the versatility of the battery clamp. Simultaneously, the clamp provided in this application can coat multiple sides of the battery. In a first state, a first portion of the grippers is configured to jointly hold two batteries, exposing two adjacent sides of each battery. In a second state, a second portion of the grippers is configured to hold one battery, and a third portion of the grippers is configured to hold the other battery, exposing two terminal surfaces of each battery. By using different states of the battery clamp, different sides and terminal surfaces of the battery are exposed, allowing the battery surface to be completely coated, resulting in high manufacturing efficiency. Using a battery clamp to hold and fix the battery eliminates the need for operator intervention, reducing harm to the human body and enhancing safety. Attached Figure Description

Embodiments of the present invention

[0029] 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.

[0030] In view of this, this application proposes a battery clamp 100. Figures 1 to 10 are schematic diagrams of some embodiments of the battery clamp 100 provided in this application. The battery clamp 100 provided in this application 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.

[0031] Please refer to Figures 1, 2, and 3. This application 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.

[0032] In the technical solution of this application, multiple grippers 102 are configured to clamp and fix two batteries 400. The drive 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.

[0033] 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.

[0034] In some embodiments, the battery 400 has multiple sides and two terminal surfaces. The multiple sides include two large sides and two small sides (i.e., a third side 405 and a fourth side 406) arranged opposite each other. In a first state, a first portion of the grippers 104 of the multiple grippers 102 clamps the two small sides (i.e., the third side 405 and the fourth side 406) of the battery 400, exposing the terminal surfaces (i.e., the first terminal surface 401 and the second terminal surface 402) of the battery 400, allowing the terminal surfaces of the battery 400 to be coated with paint. Of course, the first portion of the grippers 104 can also clamp the two large sides (i.e., the first side 403 and the second side 404) of the battery 400, depending on the actual situation. Compared to the clamping method where the first part of the gripper 104 clamps on two large sides (i.e., the first side 403 and the second side 404), the method where the first part of the gripper 104 clamps on two small sides (i.e., the third side 405 and the fourth side 406) is better, the clamping is more stable, the force on the battery 400 is more even, and the space occupied is smaller.

[0035] In some embodiments, referring to Figures 1, 2, and 3, the plurality of grippers 102 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 disposed opposite to each other. The first gripper 106 is fixedly mounted on the base 101. The second gripper 107 is connected to a 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 disposed between the first gripper 106 and the second gripper 107. The third gripper 108 is disposed closer to the first gripper 106, and the fourth gripper 109 is disposed 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.

[0036] In some embodiments, in the first state, the first part of the gripper 104 includes a first gripper 106 and a second gripper 107. The second gripper 107 is driven by the drive mechanism 103 to move toward the first gripper 106, thereby cooperating with the first gripper 106 to jointly clamp the two batteries 400.

[0037] In some embodiments, 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 closer to 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.

[0038] Referring to Figures 1 and 4, in 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.

[0039] In this embodiment, referring 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 large-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.

[0040] In some embodiments, the first support column 134 is provided with a quick-release structure 126a, which cooperates with the first gripper 106 to achieve the function of quick disassembly and replacement.

[0041] Specifically, the quick-release structure 126a includes a first latch 126, a first slot 125 formed on the first support column 134, and a first clamping jaw 106 having a first engaging platform 124 that engages with the first slot 125. The first support column 134 also has a first latch 126, which is movably mounted on the first support column 134 and located on the side of the first support column 134 opposite to the second support column 118. When the first engaging platform 124 of the first clamping jaw 106 engages with the first slot 125, the first latch 126 rotates axially, thereby abutting against the top of the first engaging platform 124 and fixing the first clamping jaw 106 to the first support column 134. When it is necessary to remove the first clamping jaw 106, the first latch 126 is rotated to separate it from the first engaging platform 124, allowing the first clamping jaw 106 to be removed and replaced. This design simplifies the disassembly process, improves installation efficiency, and thus increases production capacity.

[0042] In some embodiments, 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 the battery 400. Specifically, the material of the buffer pad 127 is not limited and can be a rubber pad, a foam pad, etc., depending on the actual situation.

[0043] 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.

[0044] 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.

[0045] In some embodiments, the third gripper 108 is detachably connected to the third support post 110. Specifically, referring to Figures 7 and 8, the third support post 110 has two first snap-fit ​​posts 128 on the side facing the first support post 134, and the two first snap-fit ​​posts 128 are spaced apart. The third gripper 108 has first snap-fit ​​holes 136 corresponding to the two first snap-fit ​​posts 128. The third support post 110 also has a snap-fit ​​block 130, which is movably mounted on the third support post 110. The snap-fit ​​block 130 includes a connected first... The first part 131 is connected to the second part 135 by bending. The second part 135 is connected to the side of the first part 131 facing the first support column 134. The first part 131 is movably mounted on the third support column 110. Specifically, a first groove is formed on the third support column 110. The first part 131 is movably mounted in the first groove. An elastic element is provided between the first part 131 and the bottom of the first groove. A second locking post 129 is provided on the side of the second part 135 away from the base 101. A second locking hole 137 corresponding to the second locking post 129 is provided on the third gripper 108. 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 gripper 108 engages with the first snap-fit ​​post 128, so that the third gripper 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 gripper 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.

[0046] In some embodiments, the elastic element is a spring.

[0047] 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, so that the terminal surfaces of the two batteries 400 (i.e., the first terminal surface 401 and the second terminal surface 402) are exposed, thereby allowing the two terminal surfaces (i.e., the first terminal surface 401 and the second terminal surface 402) 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, so that the first gripper 106 and the second gripper 107 release their grip on the two batteries 400, facilitating the next operation.

[0048] 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 battery 400, such that the two adjacent sides (i.e., the first side 40) of each battery 400 are aligned. When the coating is finished, the drive mechanism 103 drives the second gripper 107 away from the fourth gripper 109, and at the same time, the drive mechanism 103 drives the third gripper 108 away from the first gripper 106, turning 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 at the same time, the drive mechanism 103 drives the third gripper 108 closer to the first gripper 106, so that the 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 at the same time, the drive mechanism 103 drives the third gripper 108 closer to the first gripper 106, so that the two batteries 400 are clamped and fixed again.

[0049] It should be noted that the specific type of the drive mechanism 103 is not limited and can be selected according to the actual situation. In some embodiments, please refer to Figures 3 and 4. The drive mechanism 103 includes a drive member 112, a transmission member 113, and a connecting member 114. The drive member 112 is disposed on the base 101 and can provide kinetic energy to drive the transmission member 113 for transmission. 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 disposed on the connecting member 114 and are driven by the connecting member 114 to move synchronously in the second state. Specifically, in actual operation, the drive member 112 works, driving the transmission member 113 to move. The connecting member 114 is disposed 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 configuration allows one drive component 112 to simultaneously drive two components, saving on the number of parts and improving the compactness of the structure.

[0050] 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 and nut mechanism, which can convert the rotational motion of the servo motor into linear motion.

[0051] In this embodiment, referring to Figures 3 and 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 direction of the lead screw 115, thereby driving the connecting member 114 to move.

[0052] It should be noted that the battery clamp 100 provided in this application is mainly used to clamp and fix the battery 400, so as to facilitate the spraying of paint onto the surface of the battery 400. During the spraying process, the battery clamp 100 will move with the battery 400, and the paint and other materials are easily splashed onto the lead screw 115, causing the lead screw 115 and the nut 116 to jam, affecting normal production. To avoid the above situation, please refer to Figures 3 and 4. The transmission component 113 also includes a stop bar 117. The stop bar 117 is located on the side of the nut 116 away from the lead screw 115 and is fixedly connected to the base 101. 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. The stop bar 117 extends through the through hole, and both ends of the stop bar 117 are fixedly connected to both ends of the base 101. With this arrangement, the stop bar 117 can both block 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.

[0053] In some embodiments, 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 a 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 via the connecting strip 119. The connecting strip 119 can 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 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 batteries 400 of different models. 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] In some embodiments, 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.

[0058] It should be noted that the connection method between the first reference member 120 and the drive mechanism 103 is not limited and can be selected according to the actual situation. In this embodiment, please refer to Figures 9 and 10. The battery clamp 100 also includes a linkage mechanism, which includes a first linkage member 122 and a second linkage member 123 that are slidably connected. The first reference member 120 is slidably mounted on the base 101 through the first linkage member 122, and the second gripper 107 is slidably mounted on the base 101 through 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 purpose of the inclined setting is to save space and improve the compactness of the structure.

[0059] 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.

[0060] 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.

[0061] In some embodiments, the battery clamp 100 further includes a first reference support post 132, which is connected to the drive mechanism 103. A first reference member 120 is detachably connected to the first reference support post 132. When the battery clamp 100 is in the second state, the first reference member 120 can be detached 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 post 132 is similar to the connection method between the third gripper 108 and the third support post 110, and will not be described in detail here.

[0062] In some embodiments, the first reference member 120 is detachably connected to the first reference support column 132. In the first state, after the battery 400 is fixed, the first reference member 120 can be disassembled to prevent paint from being sprayed onto the first reference member 120, causing corrosion to the first reference member 120 and affecting the positioning and reference effect of the first reference member 120.

[0063] This application also proposes a spraying device 1000, as shown in Figures 11 to 13. The spraying device 1000 includes the aforementioned battery clamp 100. The specific structure of the battery clamp 100 is as described in the above embodiments. Since this spraying device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0064] In some embodiments, the spraying equipment 1000 further 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.

[0065] 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.

[0066] Please refer to Figure 13. The battery 400 includes two terminal surfaces and four side surfaces. The two terminal surfaces are the first terminal surface 401 and the second terminal surface 402. The four side surfaces are the first side surface 403, the second side surface 404, the third side surface 405 and the fourth side surface 406. The first side surface 403 and the second side surface 404 are the larger side surfaces arranged opposite each other, and the third side surface 405 and the fourth side surface 406 are the smaller side surfaces arranged opposite each other.

[0067] Specifically, referring to Figure 11, the first terminal surfaces 401 and 402 of two batteries 400 are first 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 disposed between the first clamp 106 and the third clamp 108. The first clamp 106 and the third clamp 108 clamp the battery 400 on its third side 405 and fourth side 406. The first electrode surface 401 and the second electrode surface 402 are exposed. Another battery 400 is positioned between the second gripper 107 and the fourth gripper 109. The third gripper 108 and the fourth gripper 109 clamp the third side surface 405 and the fourth side surface 406 of the battery 400. The first electrode surface 401 and the second electrode surface 402 of the battery 400 are exposed. When installing two batteries 400, the two batteries 400 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 are working, while the second spraying surface 302 is not working. The first electrode surfaces 401 and the second electrode surface 402 of the two batteries 400 are sprayed.

[0068] 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 clamp 106, the second clamp 107, the third clamp 108, and the fourth clamp 109 release their grip on the two batteries 400 (see Figure 12). The operator disassembles the third clamp 108 and the fourth clamp 109 and installs the two first reference parts 120 on the first reference support column 132, using the two first reference parts 120 and the second reference part 121 as references. Two batteries 400 are placed side by side, and 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 are working, and the first side 403 and the third side 405 of the two batteries 400 are sprayed.

[0069] 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.

[0070] At this point, the two terminal surfaces and four sides of battery 400 have been coated, and the coating of battery 400 is complete.
