[0041] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0042] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are only for the purpose of illustration and are not intended to be limiting.

[0043] In this document, ordinal numbers such as “first” and “second” cited in the present invention are merely identifiers and do not have any other meanings, such as a specific order.

[0044] In order to thoroughly understand the implementation of the utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the utility model is not limited to the specific details familiar to those skilled in the art. The preferred implementation of the utility model is described in detail below, but in addition to these detailed descriptions, the utility model can also have other implementations.

[0045] The utility model provides a glue coating device. The glue coating device can store the colloid in the metering cylinder 120 described later, and then apply the colloid in the metering cylinder 120 to the battery (glue coating work). The glue coating device includes a first metering cylinder 121 and a second metering cylinder 122. When the colloid in the first metering cylinder 121 is used up, the colloid in the second metering cylinder 122 can be used to apply to the battery, and at the same time, the first metering cylinder 121 absorbs new colloid (return glue). In this way, the first metering cylinder 121 and the second metering cylinder 122 are used alternately. During the process of returning glue to one metering cylinder 120, glue can be applied through another metering cylinder 120 without waiting, thus saving the working hours of glue coating.

[0046] Please refer to Figure 1 The glue coating device includes at least two glue coating devices 110 and a glue coating assembly 180. The glue coating device 110 includes a glue supply assembly 170 and a glue outlet assembly 113. The glue supply assembly 170 includes a first glue supply assembly and a second glue supply assembly.

[0047] The glue supply assembly 170 includes a metering cylinder 120. The metering cylinder 120 can be a cylinder of a hydraulic cylinder. The metering cylinder 120 has a receiving chamber, a cylinder inlet and a cylinder outlet. The cylinder inlet and the cylinder outlet are both connected to the receiving chamber. The cylinder inlet is used to be connected to a container for receiving glue through a glue injection valve assembly 140, a joint and a pipeline described later. A piston is provided in the receiving chamber. Along the length direction ( Figure 1 The piston is movably arranged along the length direction of the metering cylinder 120.

[0048] Thus, during the movement of the piston, the colloid can be sucked into the containing chamber from the container via the cylinder inlet, or discharged from the containing chamber via the cylinder outlet. The arrangement of the metering cylinder 120 and the piston is prior art and will not be described in detail here.

[0049] The glue supply assembly 170 also includes a glue discharging valve assembly 130. The glue discharging valve assembly 130 has an inlet and an outlet. The inlet of the glue discharging valve assembly 130 is connected to the cylinder body outlet. The glue discharging assembly 113 has a glue discharging inlet and a glue discharging outlet. The glue discharging inlet is connected to the outlet of the glue discharging valve assembly 130.

[0050] like Figure 1 As shown, specifically, the first glue supply assembly includes a first metering cylinder 121, a first glue outlet valve 131 to be described later, a first glue inlet valve 141 to be described later, a first control valve 151 to be described later, and a first drive member 161 to be described later. The second glue supply assembly includes a second metering cylinder 122, a second glue outlet valve 132 to be described later, a second glue inlet valve 142 to be described later, a second control valve 152 to be described later, and a second drive member 162 to be described later. The glue outlet valve assembly 130 includes two inlets and two outlets corresponding to each other. The correspondingly arranged inlets and outlets constitute a group of ports. In other words, the glue outlet valve assembly 130 includes two groups of ports. The inlet of the glue outlet valve assembly 130 can be connected or disconnected to the corresponding outlet. The glue outlet assembly 113 includes two glue outlet inlets and one glue outlet. The two glue outlet inlets are separated and both connected to the glue outlet.

[0051] One inlet of the glue discharging valve assembly 130 is connected to the cylinder outlet of the first metering cylinder 121. Another inlet of the glue discharging valve assembly 130 is connected to the cylinder outlet of the second metering cylinder 122. One outlet of the glue discharging valve assembly 130 is connected to one glue discharging inlet. Another outlet of the glue discharging valve assembly 130 is connected to another glue discharging inlet.

[0052] The glue discharging valve assembly 130 can selectively connect the inlet and outlet of the two groups of ports. That is, the glue discharging valve assembly 130 can connect the inlet and outlet of the first group of ports, thereby connecting the cylinder outlet of the first metering cylinder 121 to the glue discharging inlet. At this time, the inlet and outlet of the second group of ports are disconnected.

[0053] The glue discharging valve assembly 130 connects the inlet and outlet of the second group of ports, thereby connecting the cylinder outlet of the second metering cylinder 122 to the glue discharging inlet. At this time, the inlet and outlet of the first group of ports are disconnected. In this way, the glue discharging valve assembly 130 selectively connects the cylinder outlet of the first metering cylinder 121 or the cylinder outlet of the second metering cylinder 122 to the glue discharging inlet.

[0054] After the colloid stored in the first metering cylinder 121 is used up, the colloid stored in the second metering cylinder 122 can be used for gluing, and at the same time, the first metering cylinder 121 is refilled with glue. The colloid stored in the first metering cylinder 121 and the colloid stored in the second metering cylinder 122 are used alternately, and there is no need to wait for one metering cylinder 120 to refill before continuing to gluing, which has a fast processing cycle, high processing efficiency, and short processing time.

[0055] like Figure 1 As shown, the inlet of the glue coating component 180 is connected to the glue outlet of the glue outlet component 113 of at least two glue coating devices 110 to output different colloids respectively output by the at least two glue coating devices 110. For example, different colloids respectively output by the at least two glue coating devices 110 are mixed to form a mixed colloid, and the mixed colloid is applied to a preset position of the battery.

[0056] It is understood that in an embodiment not shown, the glue coating assembly can sequentially apply different glues outputted by at least two glue coating devices to the battery.

[0057] Specifically, at least two glue coating devices 110 include a first glue coating device 111 and a second glue coating device 112. The inlet of the glue coating component 180 is connected to the glue outlet of the glue outlet component 113 of the first glue coating device 111 and the glue outlet of the glue outlet component 113 of the second glue coating device 112. In this way, at least two glue coating devices 110 respectively input different colloids to the glue coating component 180. Different colloids are mixed in the glue coating component 180 to form a mixed colloid. The glue coating component 180 applies the mixed colloid to a preset position of the battery.

[0058] It is understood that in an embodiment not shown, the glue coating device may not include a glue discharging assembly. At this time, the outlet of the glue discharging valve assembly is directly connected to the inlet of the glue coating assembly 180. In this way, the outlet of the glue discharging valve assembly is the outlet of the glue coating device.

[0059] In the present embodiment, for the gluing equipment for applying colloid to the battery, after the colloid stored in the first metering cylinder 121 of each gluing device 110 is used up, the colloid stored in the second metering cylinder 122 can be used for gluing, and at the same time, the first metering cylinder 121 is refilled with glue, and the colloid stored in the first metering cylinder 121 and the colloid stored in the second metering cylinder 122 are used alternately, and there is no need to wait for one metering cylinder 120 to refill with glue before continuing to gluing, so the processing cycle is fast, the processing efficiency is high, and the processing time is short.

[0060] Preferably, if Figure 1 As shown, the glue discharging valve assembly 130 includes a first glue discharging valve 131 and a second glue discharging valve 132. The cylinder outlet of the first metering cylinder 121 is connected to the inlet of the first glue discharging valve 131. The cylinder outlet of the second metering cylinder 122 is connected to the inlet of the second glue discharging valve 132. The outlet of the first glue discharging valve 131 is connected to one glue discharging inlet. The outlet of the second glue discharging valve 132 is connected to another glue discharging inlet. In this way, by controlling the first glue discharging valve 131 and the second glue discharging valve 132 respectively, the cylinder outlet of the first metering cylinder 121 or the cylinder outlet of the second metering cylinder 122 can be selectively connected to the glue discharging inlet. Therefore, the structure of the glue discharging valve assembly 130 is simple.

[0061] Further preferably, both the first glue discharging valve 131 and the second glue discharging valve 132 can be electromagnetic one-way valves, thereby facilitating the selection of the first glue discharging valve 131 and the second glue discharging valve 132 .

[0062] It is understood that in an embodiment not shown, the first glue discharging valve and the second glue discharging valve may also be electromagnetic stop valves. In another embodiment not shown, the glue discharging valve assembly may be an electromagnetic reversing valve.

[0063] Preferably, please refer to Figure 1 The glue coating device 110 further includes a glue injection valve assembly 140. The glue injection valve assembly 140 has an inlet and an outlet. The inlet of the glue injection valve assembly 140 is connected to the container through a joint and a pipeline described below. The outlet of the glue injection valve assembly 140 is connected to the cylinder inlet.

[0064] The glue injection valve assembly 140 can selectively connect the cylinder inlet of the first metering cylinder 121 or the cylinder inlet of the second metering cylinder 122 to the container.

[0065] Specifically, the glue injection valve assembly 140 can connect the cylinder inlet of the first metering cylinder 121 to the container. At this time, the connection between the cylinder inlet of the second metering cylinder 122 and the container is disconnected.

[0066] The glue injection valve assembly 140 can connect the cylinder inlet of the second metering cylinder 122 to the container. At this time, the connection between the cylinder inlet of the second metering cylinder 122 and the container is disconnected.

[0067] When the cylinder inlet of the first metering cylinder 121 is connected to the container, the first metering cylinder 121 can be glued back. When the cylinder inlet of the second metering cylinder 122 is connected to the container, the second metering cylinder 122 can be glued back. Thus, the first metering cylinder 121 or the second metering cylinder 122 can be glued back selectively.

[0068] Furthermore, the glue injection valve assembly 140 includes a first glue injection valve 141 and a second glue injection valve 142. The cylinder inlet of the first metering cylinder 121 is connected to the outlet of the first glue injection valve 141. The cylinder inlet of the second metering cylinder 122 is connected to the outlet of the second glue injection valve 142. The inlet of the first glue injection valve 141 and the inlet of the second glue injection valve 142 are both connected to the container. In this way, by controlling the first glue injection valve 141 and the second glue injection valve 142 respectively, the first metering cylinder 121 or the second metering cylinder 122 can be selectively returned to the glue. Therefore, the structure of the glue injection valve assembly 140 is simple.

[0069] Preferably, the first glue injection valve 141 and the second glue injection valve 142 can both be air-controlled reversing valves, thereby facilitating the selection of the first glue injection valve 141 and the second glue injection valve 142 .

[0070] It is understood that in an embodiment not shown, the first glue injection valve and the second glue injection valve may also be electromagnetic stop valves. In another embodiment not shown, the first glue injection valve and the second glue injection valve may also be electromagnetic one-way valves or electromagnetic reversing valves.

[0071] As shown in FIG. 1 , the glue injection valve assembly 140 also includes a control end. The control end can control the connection between the inlet and the outlet of the glue injection valve assembly 140. The glue coating device 110 also includes a control valve assembly 150. The control valve assembly 150 has an inlet and an outlet. The outlet of the control valve assembly 150 is connected to the control end of the glue injection valve assembly 140. The inlet of the control valve assembly 150 is used to be connected to a control gas source (not shown). In this way, when the inlet and outlet of the control valve assembly 150 are connected, the control gas can be introduced into the control end of the glue injection valve assembly 140. At this time, the control gas acts on the control end of the glue injection valve assembly 140 to connect the inlet and the outlet of the glue injection valve assembly 140, so that the inlet of the metering cylinder 120 is connected to the container, and then the metering cylinder 120 can return the glue.

[0072] The control valve assembly 150 selectively connects the inlet of the first glue injection valve 141 or the inlet of the second glue injection valve 142 to the container.

[0073] Specifically, the control valve assembly 150 can connect the inlet and outlet of the first glue injection valve 141, so that the cylinder inlet of the first metering cylinder 121 is connected to the container. At this time, the connection between the inlet and outlet of the second glue injection valve 142 is disconnected.

[0074] The control valve assembly 150 can connect the inlet and outlet of the second glue injection valve 142, thereby connecting the cylinder inlet of the second metering cylinder 122 to the container. At this time, the connection between the inlet and outlet of the first glue injection valve 141 is disconnected.

[0075] Therefore, the operation of the glue injection valve assembly 140 can be determined more accurately through the control valve.

[0076] Furthermore, if Figure 1 As shown, the control valve assembly 150 includes a first control valve 151 and a second control valve 152. The inlet of the first control valve 151 is used to be connected to a control gas source through a pipeline. The outlet of the first control valve 151 is connected to the control end of the first glue injection valve 141. The inlet of the second control valve 152 is used to be connected to a control gas source. The outlet of the second control valve 152 is connected to the control end of the second glue injection valve 142. In this way, by controlling the first control valve 151 and the second control valve 152 respectively, the inlet of the first glue injection valve 141 or the inlet of the second glue injection valve 142 can be selectively connected to the container. Therefore, the structure of the control valve assembly 150 is simple.

[0077] Preferably, the first control valve 151 and the second control valve 152 can both be electromagnetic reversing valves, thereby facilitating the selection of the first control valve 151 and the second control valve 152 .

[0078] It is understood that in an embodiment not shown, the first control valve 151 and the second control valve 152 may also be electromagnetic stop valves. In another embodiment not shown, the first control valve 151 and the second control valve 152 may also be electromagnetic one-way valves.

[0079] The glue coating device further includes a controller (not shown). The controller is electrically connected to the glue discharging valve assembly 130, the glue injection valve assembly 140, the control valve assembly 150 and the driving member 160 described below to control the operation of the glue discharging valve assembly 130, the glue injection valve assembly 140, the control valve assembly 150 and the driving member 160 described below.

[0080] The controller is configured to control the second metering cylinder 122 to absorb the colloid in the container when the first metering cylinder 121 provides the colloid to the glue discharging assembly 113 .

[0081] In an embodiment not shown, the controller is configured to control the first metering cylinder to suck the glue in the container when the second metering cylinder provides glue to the glue discharging assembly.

[0082] After the colloid stored in the first metering cylinder 121 is used up, the controller can use the colloid stored in the second metering cylinder 122 to apply glue, and at the same time, make the first metering cylinder 121 return glue. The controller controls the first metering cylinder 121 and the second metering cylinder 122 to alternately return glue and apply glue. In this way, the colloid stored in the first metering cylinder 121 and the colloid stored in the second metering cylinder 122 are used alternately, and there is no need to wait for one metering cylinder 120 to return glue before continuing to apply glue, which has a fast processing cycle, high processing efficiency, and short processing time.

[0083] Please refer to Figure 1 , a piston is arranged in the metering cylinder 120. The glue coating device 110 further includes a driving member 160. The driving member 160 can generate a linear motion. The driving member 160 can be a linear motor. The driving member 160 is connected to the piston to drive the piston to move. Thus, it is convenient to control the movement of the piston to return the glue or apply the glue.

[0084] Preferably, the driving member 160 includes a first driving member 161 and a second driving member 162. The first driving member 161 is connected to the piston of the first metering cylinder 121 to drive the movement of the piston of the first metering cylinder 121. The second driving member 162 is connected to the piston of the second metering cylinder 122 to drive the movement of the piston of the second metering cylinder 122. Thus, the structure of the driving member 160 is simple.

[0085] Preferably, if Figure 1 As shown, the glue coating apparatus includes a bracket 190. At least two glue coating devices 110 are connected to the bracket 190. Thus, the structure of the glue coating apparatus is simple.
