[0039] Embodiment 1

[0040] See also Figures 1 to 5 As shown, the battery clamp provided in the present application includes a first clamping mechanism 101 , a second clamping mechanism 102 and a switching mechanism 103 .

[0041] The first clamping mechanism 101 includes a first reference positioning seat 104 and a first movable positioning seat 105. The first reference positioning seat 104 and the first movable positioning seat 105 are respectively opposite to two first side edges 107 of the battery 106. The first side edges 107 are two side edges of the battery 106 that are opposite in the first direction. When positioning the battery 106, the position of the first reference positioning seat 104 remains unchanged, and the first movable positioning seat 105 can approach or move away from the first reference positioning seat 104 along the first direction to clamp and fix the battery 106 from the first direction.

[0042] The second clamping mechanism 102 includes a second reference positioning seat 108 and a second movable positioning seat 109. The second reference positioning seat 108 and the second movable positioning seat 109 are respectively opposite to two second side edges 110 of the battery 106. The second side edges 110 are two side edges of the battery 106 that are opposite to each other in the second direction. When positioning the battery 106, the second reference positioning seat 108 remains in position, and the second movable positioning seat 109 can approach or move away from the second reference positioning seat 108 along the second direction to clamp and fix the battery 106 from the second direction.

[0043] There are multiple first movable positioning seats 105, and the switching mechanism 103 is used to switch the position of the first movable positioning seats 105 so that one of the first movable positioning seats 105 is opposite to the first side 107. When clamping different models of batteries 106, due to the different sizes of the batteries 106, the sizes of the first movable positioning seats 105 that contact the clamped surface of the battery 106 are also different. When it is necessary to switch the blueprint of the battery 106, the switching mechanism 103 is controlled by the PLC program according to the information provided by the barcode scanner at the front end of the device, so that the position of the original first movable positioning seat 105 is replaced by another first movable positioning seat 105 that is compatible with the switched battery 106, thereby realizing seamless switching of batteries 106 with different blueprints and meeting the fast-paced and small-batch needs of the market.

[0044] The present application can switch the position of the first movable positioning seat 105 according to the specific size of the battery 106 , so as to select a corresponding first movable positioning seat 105 to reliably clamp the first side 107 of the battery 106 , thereby improving the applicability of the battery clamp.

[0045] In the optional solution of this embodiment, the first direction is the length direction of the battery 106, and the second direction is the width direction of the battery 106. That is to say, the first movable positioning seat 105 is used to clamp the wide side of the battery 106. The length of the wide side is small, the clamping surface of the first movable positioning seat 105 is small, and when switching different first movable positioning seats 105, the travel distance of the first movable positioning seat 105 is also smaller, so that the device occupies less space.

[0046] In an optional solution of this embodiment, the switching mechanism 103 includes a mounting plate 111, a first guide assembly 112, a fixing frame 113 and a switching drive device 114. The mounting plate 111 is mounted on the fixing frame 113 through the first guide assembly 112, and the guiding direction of the first guide assembly 112 is the second direction. The switching drive device 114 is specifically a cylinder, and is mounted on the fixing frame 113 through a fixing plate. The driving end of the switching drive device 114 is connected to the mounting plate 111. When the battery 106 is switched, the driving shaft of the cylinder can be extended and retracted to push the mounting plate 111 to reciprocate along the second direction, so that the first movable positioning seat 105 adapted to the battery 106 installed on the mounting plate 111 is opposite to the wide side of the battery 106, so that the first movable positioning seat 105 adapted to the battery 106 can clamp the battery 106.

[0047] See also Figure 2 As shown, in an optional scheme of this embodiment, the first movable positioning seat 105 includes a first driving device 115, a second guide assembly 116 and a first movable clamping member 117; the first movable clamping member 117 is installed on the mounting plate 111 through the second guide assembly 116, and the guiding direction of the second guide assembly 116 is the first direction; the first driving device 115 is connected to the first movable clamping member 117 to drive the first movable clamping member 117 to reciprocate along the first direction.

[0048] In this embodiment, when the battery clamp has finished switching the first movable positioning seat 105, the first movable positioning seat 105 can clamp and fix the battery 106. Specifically, the first driving device 115 is a cylinder, and is installed on the mounting plate 111 through a fixing plate. The driving end of the first driving device 115 is connected to the first movable clamping member 117 through a connecting plate. When the battery 106 is clamped from the first direction, the driving shaft of the cylinder can be extended and retracted to push the connecting plate to reciprocate along the first direction, so that the first movable clamping member 117 is close to or away from the first side 107 of the battery 106.

[0049] A first reference positioning seat 104 is disposed on the opposite side of the first movable positioning seat 105. The first reference positioning seat 104 includes a first reference mounting member 118 and a first reference clamping member 119, which is mounted on the first reference mounting member 118, and a clamping surface of the first reference clamping member 119 is flush with the end of the second clamping mechanism 102.

[0050] Optionally, the first movable clamping member 117 includes a base pad, a copper strip and a PEEK strip. The base pad is provided with a mounting groove, and the copper strip is installed in the mounting groove. The first reference clamping member 119 is specifically a copper strip. The first reference mounting member 118 has a similar structure to the base pad and is also provided with a mounting groove, and the copper strip is correspondingly installed in the mounting groove. The PEEK strip is arranged on the side of the copper strip facing the battery 106 to prevent the large surface of the aluminum shell of the battery 106 from being clamped in the fixture. The PEEK strip can be pasted on the copper strip by gluing. The glue used for pasting is epoxy resin glue. The epoxy resin glue can withstand a high temperature of 1700°C, so that it can be very strong during continuous production and will not cause the PEEK strip to fall off due to the melting of the high-temperature glue.

[0051] See also Figure 3 As shown, in an optional scheme of this embodiment, the second reference positioning seat 108 includes a second reference mounting member 120, a third guide assembly 121 and a second reference clamping member 122; the second reference clamping member 122 is installed on the second reference mounting member 120 through the third guide assembly 121; the second movable positioning seat 109 includes a second driving assembly, a second movable mounting member 124, a third guide assembly 121 and a second movable clamping member 125; the second movable clamping member 125 is installed on the second movable mounting member 124 through the third guide assembly 121; the second driving assembly is connected to the second movable mounting member 124 to drive the second movable mounting member 124 to reciprocate along the second direction; the guiding direction of the third guide assembly 121 is the first direction.

[0052] In this embodiment, when clamping and positioning the battery 106, the battery 106 is placed between the first reference positioning seat 104, the first movable positioning seat 105, the second reference positioning seat 108 and the second movable positioning seat 109. First, the first clamping mechanism 101 is actuated: the second movable positioning seat 109 moves toward the second reference positioning seat 108 to push the battery 106 to the second reference positioning seat 108, so that the battery 106 abuts against the clamping surface of the second reference positioning seat 108, and the two long sides of the battery 106 are clamped. Then, the second clamping mechanism 102 is actuated: the first movable positioning seat 105 moves toward the first reference positioning seat 104 to push the battery 106 to the first reference positioning seat 104. At this time, since the long side of the battery 106 has been clamped by the first clamping mechanism 101, the battery 106 itself cannot move, and the slider of the third guide assembly 121 can move along the guide rail, so that the second reference clamping member 122 and the second movable clamping member 125 connected to the slider can drive the clamped battery 106 to move along the first direction until the battery 106 abuts against the first reference positioning seat 104, and the two short sides of the battery 106 are also clamped. By adopting the above method, after the battery 106 is clamped and positioned in the second direction, the battery 106 is clamped in this direction and the position will not change. Even if the battery 106 is subsequently clamped and positioned in the first direction, the battery 106 will not move, thereby improving the accuracy of clamping and positioning the battery 106.

[0053] Furthermore, at least two sliders can be provided on the guide rail of the third guide assembly 121. When the second reference clamp 122 and the second movable clamp 125 clamp the battery 106, the impact force received by the two can be evenly transmitted to multiple sliders, thereby increasing the service life of the mechanism. Since the third guide assembly 121 is located close to the welding area, and considering that welding slag will enter the inside of the guide rail, the third guide assembly 121 uses a high-assembly form in the dustproof series of products. The slider has a built-in scraper plate that can scrape away dust and sludge on the guide rail, thereby increasing the service life of the mechanism. In addition, the distance between the slider and the guide rail of the high-assembly guide rail is relatively large, and the tip of the vacuum gun can more easily penetrate into the area where welding slag is easily concentrated between the slider and the guide rail to absorb the welding slag, which is convenient for maintenance, saves manpower, and further increases the service life of the mechanism.

[0054] Specifically, the second reference clamp 122 and the second movable clamp 125 have similar structures, both including a base pad, a copper strip and a PEEK strip. The base pad is provided with an installation groove, and the copper strip is installed in the installation groove. The PEEK strip is arranged on the side of the copper strip facing the battery 106 to prevent the large surface of the aluminum shell of the battery 106 from being scratched in the fixture. The PEEK strip can be pasted on the copper strip by gluing, and the glue used for pasting is epoxy resin glue. The epoxy resin glue can withstand a high temperature of 1700°C, so that it can be very strong during continuous production, and the PEEK strip will not fall off due to the melting of the high-temperature glue.

[0055] In an optional solution of this embodiment, the second driving assembly includes a second driving device 123 and a fourth guide assembly 126. The second movable mounting member 124 is connected to the slider of the fourth guide assembly 126, and the guiding direction of the fourth guide assembly 126 is the second direction. The second driving device 123 is specifically a cylinder, and the driving end of the cylinder is connected to the second movable mounting member 124. When the driving shaft of the second driving device 123 is extended and retracted, the second movable mounting member 124 can be pushed to reciprocate along the second direction to drive the second reference clamping member 122 to clamp and fix the long side of the battery 106.

[0056] Embodiment 2

[0057] The battery clamp in the second embodiment is an improvement on the above embodiment, and the technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in the second embodiment.

[0058] See also Figure 4 and Figure 5 As shown, in an optional solution of this embodiment, the battery clamp also includes a lifting mechanism and a support frame 127. The first clamping mechanism 101, the second clamping mechanism 102, the switching mechanism 103 and the lifting mechanism are all installed on the top of the support frame 127. The lifting mechanism is mainly used to carry and lift the battery 106. The lifting mechanism includes a lifting drive assembly 128 and a bearing assembly 129, and the lifting drive assembly 128 is connected to the bearing assembly 129 to drive the bearing assembly 129 to rise and fall; the bearing assembly 129 is used to support the battery 106.

[0059] Specifically, the lifting drive assembly 128 includes a motor, a screw assembly and a vertical slide rail assembly. The motor is connected to the bearing assembly 129 through the screw assembly to drive the bearing assembly 129 to lift and lower. The motor can lift batteries 106 at different heights, and the movement accuracy can reach 0.02mm. The motor is small and convenient, takes up little space, reduces the overall height of the full welding fixture by 30%, makes the overall fixture structure more stable, and reduces the overall full welding equipment by 15% in height. The vertical slide rail assembly is arranged between the bearing assembly 129 and the support frame 127 to guide the lifting and lowering movement of the bearing assembly 129.

[0060] In the optional solution of this embodiment, specifically, the bearing assembly 129 includes a bearing pad 130, a fifth guide assembly 131, an adapter plate 132, a sixth guide assembly 133 and a bottom support 134. The bearing pad 130 includes a bearing plate and a PEEK pad, the bearing plate is mounted on the adapter plate 132 through the fifth guide assembly 131, and the adapter plate 132 is mounted on the bottom support 134 through the sixth guide assembly 133; the guiding direction of one of the fifth guide assembly 131 and the sixth guide assembly 133 is the first direction, and the guiding direction of the other is the second direction; the bottom support 134 is connected to the lifting drive assembly 128.

[0061] In this embodiment, when the first clamping mechanism 101 and the second clamping mechanism 102 push the battery 106 to move, it is actually the sliders of the fifth guide assembly 131 and the sixth guide assembly 133 that move along the corresponding guide rails. There is no sliding friction between the battery 106 and the bearing pad 130, which can prevent the bottom of the battery 106 from being scratched by friction.

[0062] Specifically, the bottom support 134 includes a bottom support plate and side plates. The bottom support plate is used to carry the battery. The two ends of the bottom support plate are provided with side plates, which can limit the movement of the adapter plate 132. The adapter plate 132 is provided with a limit plate to limit the movement of the bearing pad 130.

[0063] In an optional solution of this embodiment, a reset member 135 is provided between the adapter plate 132 and the bottom support member 134 ; and / or a reset member 135 is provided between the bearing pad 130 and the adapter plate 132 .

[0064] In this embodiment, the reset member 135 includes a compression spring and a half-thread screw. Between the adapter plate 132 and the bottom support member 134, the threaded portion of the half-thread screw is connected to one of them, and the other is provided with a through hole. The head of the half-thread screw passes through the through hole and can reciprocate relative to the through hole, and the compression spring is sleeved outside the half-thread screw. Between the bearing pad 130 and the adapter plate 132, the threaded portion of the half-thread screw is connected to one of them, and the other is provided with a through hole. The head of the half-thread screw passes through the through hole and can reciprocate relative to the through hole, and the compression spring is sleeved outside the half-thread screw. The compression spring and the half-thread screw play a role in resetting the mechanism. The half-thread screw provides guidance for the compression spring and brings limitation to the mechanism, and the compression spring provides a power source for resetting.
