[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Reference Figure 1 , Figure 3 , Figure 4 The spacing adjustment formation component of one aspect of the present invention includes: a bracket 100; a probe assembly, which is arranged on the bracket 100; a negative pressure assembly 112, which is arranged on the bracket 100; an adjustment mechanism, which is arranged on the bracket 100 and is used to adjust the distance between the probe assembly and the negative pressure assembly 112, and the adjustment mechanism is formed with a channel for removing the probe assembly and / or the negative pressure assembly 112 from the right side.

[0032] By applying the spacing adjustment formation assembly of the present embodiment, when performing equipment maintenance, the probe assembly or the negative pressure assembly 112 can be directly removed from the bracket 100, and then the probe assembly and the negative pressure assembly 112 can be directly taken out through the yield structure. The entire process does not require disassembly of the adjustment mechanism. Compared with the existing maintenance steps that require disassembly of the adjustment mechanism, the disassembly time of the probe assembly and the negative pressure assembly 112 is effectively saved, and the equipment maintenance efficiency is greatly increased.

[0033] Among them, the adjustment mechanism can avoid the channel for removing the probe assembly and / or the negative pressure assembly 112 from the right side in a variety of ways. For example, the adjustment mechanism is partially set above the probe assembly and the negative pressure assembly 112, so that the right side of the probe assembly and the negative pressure assembly 112 is not blocked. When the equipment needs to be maintained, the negative pressure assembly 112 and the probe assembly can be removed from the right side without disassembling the adjustment mechanism. The adjustment mechanism can also be partially set on the left side of the probe assembly and the negative pressure assembly 112, so that the right side of the probe assembly and the negative pressure assembly 112 is not blocked. When the equipment needs to be maintained, the negative pressure assembly 112 and the probe assembly can be removed from the right side without disassembling the adjustment mechanism.

[0034] Among them, the adjustment mechanism can adjust the distance between the negative pressure component 112 and the probe component in various ways. For example, a cylinder or a hydraulic cylinder is arranged on the negative pressure component 112 to drive the negative pressure component 112 to move relative to the probe component, or a linear motor or a motor gear rack structure, etc., is used to drive the negative pressure component 112 to move relative to the probe component.

[0035] It should be noted that the adjustment mechanism can be connected to the probe component or the negative pressure component 112 to adjust the distance between the probe component and the negative pressure component 112, or a non-contact method such as magnetic drive can be used to adjust the distance between the probe component and the negative pressure component 112.

[0036] As Figure 1 、 Figure 5 shown, the negative pressure component 112 includes a plurality of negative pressure cups arranged in the left-right direction. Each of the plurality of negative pressure cups is connected to a vacuum pumping device. During the formation and grading process, the negative pressure component 112 can be controlled so that the nozzles of the plurality of negative pressure cups simultaneously abut against the liquid injection holes of the plurality of batteries in the battery tray, and only a vacuum pumping operation is required.

[0037] As Figures 2 to 4 shown, the probe component includes a positive probe component 113 and a negative probe component 111 that are simultaneously arranged on the bracket 100. The negative pressure component 112 is arranged between the positive probe component 113 and the negative probe component 111. The adjustment mechanism includes a first right lead screw 126 arranged above the positive probe component 113. A first right nut 127 and a second right nut 128 are in threaded cooperation with the first right lead screw 126. The first right nut 127 is connected to the negative probe component 111, and the second right nut 128 is connected to the positive probe component 113. At this time, the first right lead screw 126 is arranged above the positive probe component 113 and the negative probe component 111. When the first right lead screw 126 rotates, the first right nut 127 and the second right nut 128 move forward or backward simultaneously, driving the positive probe component 113 and the negative probe component 111 to move relative to the negative pressure component 112 simultaneously, ensuring the synchronous movement of the positive probe component 113 and the negative probe component 111. At the same time, the first right lead screw 126 is arranged above the positive probe component 113 and the negative probe component 111. At this time, the first right lead screw 126 can avoid the channels for the probe component and / or the negative pressure component 112 to be removed from the right side, playing a role of making way, that is, a channel is formed below the first right lead screw 126.

[0038] As Figure 2As shown in the figure, the probe assembly includes a positive probe assembly 113 and a negative probe assembly 111. A plurality of positive probes arranged in the left-right direction are provided on the positive probe assembly 113, and a plurality of negative probes arranged in the left-right direction are provided on the negative probe assembly 111. The negative pressure assembly 112 is arranged between the positive probe assembly 113 and the negative probe assembly 111. At this time, the distance between the negative pressure assembly 112 and the probe assembly referred to in this embodiment should be understood as the position of the negative pressure assembly 112 between the positive probe assembly 113 and the negative probe assembly 111 according to the situation. Of course, according to the battery structure, the negative pressure assembly 112 can also be arranged on one side of the positive probe assembly 113 and the negative probe assembly 111. At this time, the distance between the negative pressure assembly 112 and the probe assembly can be understood as the distance between the positive probe assembly 113 and the negative pressure assembly 112.

[0039] As Figure 3 shown in the figure, in order to facilitate the automation of the position adjustment of the negative pressure assembly 112 between the positive probe assembly 113 and the negative probe assembly 111, the adjustment mechanism includes two first bevel gear sets 124 and a first driving motor 121 arranged on the bracket 100. The first driving motor 121 drives the first right lead screw 126 to rotate through the two first bevel gear sets 124. Of course, the first right lead screw 126 can also be driven to rotate by setting a pneumatic motor or a hydraulic motor. Of course, the first right lead screw 126 can also be driven to rotate manually. At this time, the use of the two bevel gear sets can make the entire adjustment mechanism arranged around the positive probe assembly 113 and the negative probe assembly 111 when viewed from the left-right direction, so that the right side of the positive probe assembly 113 and the negative probe assembly 111 will not be blocked.

[0040] As Figure 3 、 Figure 4As shown, the bracket is also provided with a first synchronous pulley group 122 and a first driving shaft 123, the first driving motor 121 drives the first driving shaft 123 to rotate through the first synchronous pulley group 122, the right end of the first driving shaft 123 drives the first right lead screw 126 to rotate through two first bevel gear groups 124, and the left end of the first driving shaft 123 drives the first left lead screw 1210 to rotate through the first bevel gear group 124, and the first left lead screw 1210 is threadedly matched with a first left nut 1211 and a second left nut 1212, the first left nut 1211 can be detachably matched with the negative probe assembly 111, and the second left nut 1212 can be detachably matched with the positive probe assembly 113; when the first driving motor 121 When the machine 121 rotates, the first motor drives the first drive shaft 123 to rotate through the synchronous pulley; at this time, the right end of the first drive shaft 123 transmits the torque to the first right screw 126 through two bevel gear sets, thereby forming a yield structure; and the left end of the first drive shaft 123 transfers the torque to the first left screw 1210 through the bevel gear set, so that the first left screw 1210 drives the first left nut 1211 and the second left nut 1212 to move forward and backward; here, the negative probe assembly 111 can be driven by the first left nut 1211 and the first right nut 127 at the same time, and the positive probe assembly 113 can be driven by the second left nut 1212 and the second right nut 128 at the same time, thereby ensuring the stability of the drive.

[0041] In detail, the synchronous belt drive can also make the first drive motor 121 farther away from the first drive shaft 123, so that the first drive motor 121 can be placed in a relatively free place on the bracket 100, thereby improving the utilization rate of the bracket 100.

[0042] Here, the first left nut 1211 can be detachably matched with the negative pole probe assembly 111 in a variety of ways, such as by magnet attraction or screw fixation, or by setting a pin on the first left nut 1211 and a small hole matching the pin on the negative pole probe assembly 111; since the first left screw 1210 is set on the left side of the negative pressure assembly 112 and the negative pole probe assembly 111 at this time, the first left screw 1210 will not hinder the probe assembly and the negative pressure assembly 112 from being removed from the right side, and objectively plays the role of a giving way structure.

[0043] like Figure 5 , Figure 6As shown, a fixing block 163 is provided on the bracket 100, and the fixing block 163 is connected to the first right nut 127. A slider 162 is provided on the fixing block 163. A slide rail 161 extending forward and backward is provided on the bracket 100. The slider 162 cooperates with the slide rail 161, and the fixing block 163 is detachably connected to the negative electrode probe assembly 111; at this time, the first right nut 127 drives the fixing block 163 to move forward and backward, so that the negative electrode probe assembly 111 connected to the fixing block 163 moves forward and backward. When maintenance is required, the negative electrode probe assembly 111 only needs to be removed from the fixing block 163.

[0044] Here, the fixing block 163 and the negative pole probe assembly 111 can be detachably connected in a variety of ways, such as fixing the fixing block 163 and the negative pole probe assembly 111 by screws, or providing a T-shaped slide groove extending left and right on the fixing block 163, and providing a T-shaped slide boss on the negative pole probe assembly 111. When installing the negative pole probe assembly 111, the T-shaped slide boss can be directly inserted into the T-shaped slide groove, and the structure of the T-shaped slide groove can prevent the negative pressure probe from falling. During maintenance, the T-shaped slide boss only needs to be slid out of the T-shaped slide groove.

[0045] Similarly, the positive pressure probe assembly can also be connected to the second right nut 128 in the above manner.

[0046] like Figure 1 , Figure 3 , Figure 4 As shown, the adjustment mechanism includes a second right screw 136 arranged above the negative pressure assembly 112, and the second right screw 136 is threadedly matched with a third right nut 134, and the third right nut 134 is connected to the negative pressure assembly 112; at this time, the second right screw 136 can drive the negative pressure assembly 112 to move forward and backward by driving the third right nut 134. At the same time, since the second right screw 136 and the third right nut 134 are both located below the negative pressure assembly 112, when the negative pressure assembly 112 and the probe assembly are removed from the right side, the second right screw 136 and the third right nut 134 can avoid the channel for the probe assembly and / or the negative pressure assembly 112 to be removed from the right side, playing the role of a giving way structure, that is, a channel is formed below the second right screw 136.

[0047] Similar to the first right lead screw 126 , the second right lead screw 136 can also be rotated in a variety of ways to cause the third nut negative pressure assembly 112 to move forward and backward.

[0048] like Figure 3 , Figure 4As shown, in the actual spacing adjustment formation component, the adjustment mechanism is divided into two parts, a first adjustment device 120 and a second adjustment device 130, and the first adjustment device 120 and the second adjustment device 130 are arranged relative to each other front to back, wherein the first adjustment device 120 includes a first right lead screw 126, a first right nut 127 and other components, which are used to drive the positive probe assembly 113 and the negative probe assembly 111 to slide back and forth, and the second adjustment device 130 includes a second right lead screw 136 and a second right nut 128 and other components, which are used to drive the negative pressure assembly 112 to slide back and forth; since the second right lead screw 136 is located at the rear end of the bracket 100, when the positive probe assembly 113, the negative probe assembly 111 and the negative pressure assembly 112 are all located directly below the first right lead screw 126, there will be a positional misalignment between the third right nut 134 and the negative pressure assembly 112 in the up and down directions, and at this time, a connecting rod is required to connect the third right nut 134 and the negative pressure assembly 112.

[0049] like Figures 1 to 3 As shown, in order to enable the spacing adjustment formation assembly to simultaneously perform formation and capacity division on two rows of batteries, in practice, Figure 2 As shown, the number of positive probe assemblies 113, negative probe assemblies 111 and negative pressure assemblies 112 on the bracket 100 is 2, and each negative pressure assembly 112 is arranged between a positive probe assembly 113 and a negative probe assembly 111, and the front and rear positive probe assemblies 113 and positive probe assemblies 113, the negative probe assemblies 111 and the negative probe assemblies 111, and the negative pressure assemblies 112 and the negative pressure assemblies 112 are connected by connecting rods. When the front first adjustment device 120 drives the positive probe assembly 113 and the negative probe assembly 111, the rear positive probe assembly 113 and the negative probe assembly 111 can also move at the same time, and when the rear second adjustment device 130 drives the negative pressure assembly 112, the front negative pressure assembly 112 can also move together; while ensuring the giving way effect of the giving way structure, the space occupied by the adjustment mechanism is effectively saved, and the space occupied by the equipment is reduced.

[0050] like Figure 3 As shown, similar to the first adjusting device 120 , the adjusting mechanism further includes a second driving motor 131 disposed on the bracket 100 , and the second driving motor 131 drives the second right lead screw 136 to rotate through two second bevel gear sets 133 .

[0051] Among them, the structure of the first adjustment device 120 can also be referred to. The second driving motor 131 drives the second driving shaft 138 to rotate through the second synchronous pulley set 132. The right end of the second driving shaft 138 drives the second right lead screw 136 to rotate through two second bevel gear sets 133. The left end of the second driving shaft 138 drives the second left lead screw 137 to rotate through the second bevel gear set 133. A third left nut 135 is in threaded fit with the second left lead screw 137, and the third left nut 135 is detachably connected to the negative pressure assembly 112. At this time, the negative pressure assembly 112 is driven by the third right nut 134 and the third left nut 135 at the same time, effectively ensuring the stability of the drive.

[0052] Such as Figure 1 , Figure 3 As shown, in order to accurately detect the movement positions of the whole machine probe assembly, the negative electrode probe assembly 111 and the negative pressure assembly 112, two encoders 150 can be arranged on the bracket 100. The two encoders 150 are respectively sleeved on the first driving shaft 123 and the second driving shaft 138 and can detect the rotation positions of the two driving shafts, so as to detect the relative positions among the positive pressure probe assembly, the negative pressure assembly 112 and the negative electrode probe assembly 111.

[0053] In this embodiment, both the first right lead screw 126 and the first left lead screw 1210 can adopt the form of connecting two lead screws through a coupling, avoiding the problem that long lead screws are difficult to process.

[0054] In the second aspect of this embodiment, a formation and formation capacity testing device is provided, including a base 200, and the above-mentioned spacing-adjusting formation assembly is arranged above the base 200. A lifting device 210 is also arranged between the base 200 and the probe assembly. When the battery tray is transported below the probe assembly, the lifting device 210 can be controlled to lift the battery tray, so that the probe assembly and the negative pressure assembly 112 can perform formation and formation capacity testing operations on the battery in the battery tray.

[0055] During the formation and formation capacity testing process, in order to dissipate heat from the battery in time, a plurality of heat dissipation components 140 can be arranged on the bracket 100. A plurality of fans are arranged on each heat dissipation component 140, and the fans provide flowing air for the battery to dissipate heat from the battery.

[0056] Such as Figure 1 As shown, lifting devices 210 are arranged on both the front and rear sides of the base 200. At this time, a transport belt can be arranged between the lifting devices 210 on the front and rear sides. When the belt transports the battery tray carrying the battery below the probe assembly, the position sensor 220 can detect whether the battery tray is in place. When the battery tray is in place, the lifting device 210 can be controlled to lift the tray, improving the automation degree of the entire production process.

[0057] During the formation and grading process, either the tray can be driven closer to the probe assembly, or the entire spacing-adjustable formation assembly can be driven closer to the tray; when driving the entire spacing-adjustable formation assembly closer to the tray, the bracket 100 can be driven to move up and down relative to the base 200 by a lifting cylinder provided on the bracket 100, or the bracket 100 can be driven to move up and down by components such as a motor and a cylinder provided on the base 200.

[0058] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the relevant art.
