The following embodiments are used to illustrate the present utility model but do not limit the scope of the present utility model.

[0048] Generally, the laser or plasma cleaning module on the assembly line is usually a single-direction cleaning source, that is, it can only clean one side of the square battery 800 at the same time. The utility model provides a battery clamping and flipping combined device, which is used for clamping and flipping the square battery 800 during laser or plasma cleaning before UV spraying, so as to realize the cleaning of six sides of the square battery. It is defined that the direction in which the two jaw assemblies 301 approach or separate from each other is the X-axis direction, and the Z-axis direction is vertically perpendicular to the X-axis direction.

[0049] As Figures 1 to 9 shown, the battery clamping and flipping linkage device of the utility model includes a workbench 100, which is composed of two support platforms 101 spaced relatively.

In the utility model, there are two Z-axis slide rails 6031, and the two Z-axis slide rails 6031 are arranged in parallel and spaced apart on the fixed bracket 604 in such a way that their length directions extend along the Z-axis direction. Two sliders are slidably connected to each Z-axis slide rail 6031, and the four sliders on the two Z-axis slide rails 6031 are jointly fixed to a Z-axis slide plate 6033. The fixed end of the Z-axis driving cylinder 6032 is fixed below the fixed bracket 604, and its driving end faces upward and is connected to the bottom surface of the Z-axis slide plate 6033 through a floating joint 6034, and the floating joint 6034 can further ensure the stability of the operation of the Z-axis linear module.

[0052] The top surface of the Z-axis slide plate 6033 is fixedly connected with a mounting plate 6026, and the adsorption and bearing platform 601 and the rotation assembly I602 are arranged on the mounting plate 6026.

[0053] The rotation assembly I602 includes a rotation motor I6021, a synchronous transmission wheel set I6022, a pneumatic slip ring 6024, and a rotating part with a hollow central axis. The rotating part includes a hollow rotating shaft 6023, a hollow bearing seat 6025a, and a bearing sleeve 6025b, and its composition structure is the prior art and will not be elaborated here.

[0054] The synchronous transmission wheel set I6022 includes a driving wheel, a driven wheel, and a synchronous belt connecting the driving wheel and the driven wheel.

[0055] A motor fixing bracket 6026b is fixedly connected to the lower surface of the mounting plate 6026. The fixed end of the rotating motor I 6021 is fixedly connected to the motor fixing bracket 6026b. The driving end of the rotating motor I 6021 is connected to the driving wheel of the synchronous transmission wheel set I 6022, and the driven wheel of the synchronous transmission wheel set I 6022 is connected to the rotating shaft 6023. In addition, to prevent the driven wheel of the synchronous transmission wheel set I 6022 from falling off the rotating shaft 6023, a fastening nut 6027 is also sleeved on the outer peripheral surface of the lower end of the rotating shaft 6023, and the driven wheel of the synchronous transmission wheel set I 6022 is placed on the fastening nut 6027.

The flange head of the bearing seat 6025a is fixedly connected to the upper surface of the mounting plate 6026, and the rotating shaft head is placed above the flange head of the bearing seat 6025a.

[0057] Start the rotating motor I 6021, and the rotating motor I 6021 drives the rotating shaft 6023 to rotate around the central axis of the rotating shaft 6023 through the synchronous transmission wheel set I 6022.

[0058] An adsorption and bearing platform 601 is fixedly connected to the upper surface of the rotating shaft head. The square battery 800 is placed on the adsorption and bearing platform 601. To prevent the square battery 800 from shifting or falling when the adsorption and bearing platform 601 rotates with the rotating shaft 6023, a vacuum chuck 6013 is provided on the adsorption and bearing platform 601.

[0059] The adsorption and bearing platform 601 of the present utility model is a long rectangle. A strip-shaped air inlet channel 6011 is provided in the adsorption and bearing platform 601 along its length direction. An air inlet 6011a is provided at the central part of the bottom surface of the adsorption and bearing platform 601. Six suction cup mounting holes are provided at intervals along the length direction of the upper surface of the adsorption and bearing platform 601. The air inlet channel 6011, the air inlet 6011a and each suction cup mounting hole are communicated. A vacuum chuck 6013 is provided in each suction cup mounting hole. To make the vacuum chuck 6013 communicate with the vacuum pipeline, the bottom end of the rotating shaft rod part of the rotating shaft 6023 is connected to a pneumatic slip ring 6024. The pneumatic slip ring 6024 is connected to a vacuum pipeline (not shown in the figure). The vacuum pipeline is connected to a vacuum generator. The vacuum pipeline, the pneumatic slip ring 6024, the hollow cavity of the rotating shaft 6023 and the air inlet channel 6011 form a gas channel. Start the vacuum generator, and it controls the suction and release of the square battery 800 by the vacuum chuck 6013. Among them, the pneumatic slip ring 6024 ensures that the vacuum pipeline does not rotate with the rotating shaft 6023 when the rotating shaft 6023 rotates.

[0060] In general actual production, a positioning block is provided on the top surface of the square battery 800. In order to quickly and accurately adsorb the square battery 800 onto the adsorption and bearing platform 601, a positioning groove 6014 adapted to the positioning block on the top surface of the square battery 800 is also provided on the adsorption and bearing platform 601 of the present utility model.

[0061] It is defined that the surface of the square battery 800 in contact with the adsorption and bearing platform 601 is its top surface, the surface opposite to the top surface is the bottom surface, the surfaces at both ends along its length are the side surfaces, and the other two surfaces are the large surfaces.

[0062] The square battery 800 is placed on the adsorption and bearing platform 601 along its length direction. And for the convenience of positioning, the top surface of the square battery 800 is placed downward on the adsorption and bearing platform 601. The vacuum generator is started, and the above-mentioned vacuum suction cup 6013 firmly adsorbs the square battery 800.

[0063] The rotation motor I 6021 is started, and the rotating shaft 6023 drives the adsorption and bearing platform 601 and the square battery 800 on the adsorption and bearing platform 601 to rotate synchronously. The laser or plasma cleaning module first cleans one of the two large surfaces of the square battery 800. After the cleaning is completed, the rotation angle is selected to clean the other large surface or the two side surfaces.

[0064] In order to complete the cleaning of the top surface and the bottom surface of the square battery 800, a clamping and rotating mechanism 200 is also provided on the two support platforms 101.

[0065] The clamping and rotating mechanism 200 includes an X-axis clamping assembly 300 and a rotating assembly II 400 which are arranged in parallel and at intervals. A synchronous transmission assembly II 500 is also connected between the X-axis clamping assembly 300 and the rotating assembly II 400, so that the X-axis clamping assembly 300 can drive the rotating assembly II 400 to move along the X-axis synchronously, and the rotating assembly II 400 can drive the X-axis clamping assembly 300 to rotate synchronously.

[0066] Specifically, the X-axis clamping assembly 300 includes an X-axis linear module and two jaw assemblies 301 oppositely arranged on the X-axis linear module. A synchronous transmission assembly II 500 is connected between each jaw assembly 301 and the rotating assembly II 400.

[0067] The X-axis linear module is a double spiral lead screw variable pitch module, including a variable pitch lead screw 3021, two lead screw nuts 3022, a lead screw drive motor 3023 and two groups of lead screw slide rails 3024.

[0068] The lead screw drive motor 3023 is a servo motor. Its fixed end is fixedly arranged on a support platform 101, and its drive end is connected to one end of the variable pitch lead screw 3021. The other end of the variable pitch lead screw 3021 passes through the avoidance hole on the fixed bracket 604 along the X-axis direction and is connected to the other support platform 101.

[0069] Two lead screw nuts 3022 are respectively connected to the pitch-changing lead screw 3021 and are respectively located on both sides of the fixed bracket 604 along the X direction. The two lead screw nuts are respectively connected to the pitch-changing lead screw, that is, a double-lead screw is formed. The thread rotation directions at both ends of the double-lead screw are opposite, so as to drive the two lead screw nuts 3022 to displace towards each other or away from each other at the same speed. To facilitate the installation of other subsequent components, each lead screw nut 3022 of the present utility model is composed of a nut bottom plate 3022a and a nut back plate 3022b vertically connected to the nut bottom plate, and each nut bottom plate 3022a is connected to the pitch-changing lead screw 3021.

[0070] There are two sets of lead screw slide rails 3024, and one set of lead screw slide rails 3024 is provided on each of the two support platforms 101. The lead screw slide rails 3024 are arranged on a support platform 101 in a manner that its length extends along the X-axis direction, and the two lead screw slide rails 3024 on the same support platform 101 are respectively arranged on both sides of the pitch-changing lead screw 3021. A slider is slidably connected to each lead screw slide rail 3024, and the sliders on the two lead screw slide rails 3024 on the same support platform 101 are commonly fixed to their corresponding lead screw nuts 3022. A clamping jaw assembly 301 is fixed to each lead screw nut 3022. At this time, the above-mentioned adsorption and bearing platform 601 is located between the two clamping jaw assemblies 301, and the two clamping jaw assemblies 301 can perform a clamping action on the square battery 800 on the adsorption and bearing platform 601.

Each clamping jaw seat 3011 includes a bottom plate 3011a and a vertical plate 3011b connected to the bottom plate. The bottom plate 3011a is fixed to the lead screw nut 3022, and an installation through hole is provided at the upper end of the vertical plate 3011b. Each clamping jaw rotating shaft 3013 passes through the installation through hole of the vertical plate 3011b along the X direction. One end of it is connected to the clamping jaw 3012, and the other end is connected to one end of the synchronous transmission assembly II 500, and the positions of the two clamping jaws 3012 are adapted to the position of the square battery 800 on the adsorption and bearing platform 601. To support the clamping jaw rotating shaft 3013, the bearing seat II is sleeved in the above-mentioned installation through hole and fixed to it, and the clamping jaw rotating shaft 3013 is rotatably sleeved in the bearing seat II.

[0072] Start the lead screw drive motor 3023 to drive the two clamping jaws 3012 to displace towards each other or away from each other at the same speed, so as to perform a clamping or separating action on the square battery 800 on the adsorption and bearing platform 601.

[0073] In addition, to continuously monitor the clamping force applied to the square battery 800 and avoid damage caused by excessive clamping force or dropping due to insufficient clamping force, a pressure sensor 700 is further provided on one of the jaw assemblies 301. One end of the pressure sensor 700 abuts against the nut back plate 3022b of the lead screw nut 3022, and the other end abuts against the side of the bottom plate 3011a of the jaw seat 3011. To enable the pressure sensor 700 to function effectively, two jaw seat slide rails 701 are provided on the upper surface of the nut bottom plate 3022a of one of the lead screw nuts 3022 in the X-axis direction. The two jaw seat slide rails 701 are arranged in parallel at intervals. A slider is slidably connected to each jaw seat slide rail 701. The bottom surface of the jaw seat 3011 corresponding to the lead screw nut 3022 is fixedly connected to the slider on the two jaw seat slide rails 701. When the two jaw assemblies 301 approach each other to clamp the square battery 800, one of the jaw seats 3011 is subjected to a clamping force, thereby pushing the jaw seat 3011 to move slightly along the jaw seat slide rail 701 towards the direction close to the nut back plate 3022b. As a result, the pressure sensor 700 is squeezed, and the magnitude of the clamping force between the two jaws 3012 can be obtained.

One end of each cam follower 5021 is fixedly connected to the nut back plate 3022b through a connecting member, and the other end of each cam follower 5021 is placed in the annular groove of the guide wheel 5022. Each spline 503 includes a spline shaft and a flange outer ring, which are prior art and will not be elaborated here.

[0076] One end of the jaw rotating shaft 3013 in each of the above-mentioned jaw assemblies 301 is connected to the driven wheel of the synchronous transmission wheel set II 501. The driving wheel of the synchronous transmission wheel set II 501 is sleeved on the flange outer ring of the spline 503, and a guide wheel 5022 is also sleeved on the flange outer ring, and the guide wheel 5022 is located on the side close to the square battery 800.

The fixed end of the rotating motor II 401 is fixedly connected to a support platform 101 provided with a lead screw driving motor 3023. The rotating rod 402 passes through an avoidance hole on the fixed bracket 604 along the X-axis direction, and its two ends are respectively rotatably connected to the support platform 101. The two ends of the rotating rod 402 are respectively connected to one end of its corresponding spline shaft through a coupling 702. The other end of the spline shaft of the spline 503 near the rotating motor II 401 is connected to the driving end of the rotating motor II 401 through a coupling 702, and the other end of the spline shaft of the spline 503 far from the rotating motor II 401 is rotatably connected to another corresponding support platform 101.

[0078] In addition, to enhance the synchronization effect of the synchronous transmission assembly II 500, a tension pulley 504 is further provided on the nut back plate 3022b in each jaw assembly 301. One end of the tension pulley 504 is fixedly connected to the nut back plate 3022b, and the other end abuts against the synchronous belt of the synchronous transmission assembly II 500.

[0079] When the lead screw driving motor 3023 drives the two jaws 3012 to approach or separate from each other, the follower assemblies 502 in the two synchronous transmission assemblies II 500 on the two jaws 3012 synchronously drive the flange outer rings of their corresponding splines 503 to approach or separate from each other synchronously. When the rotating motor II 401 is started, the rotating rod 402 and the two splines 503 rotate around their X-axis central axes, and the two jaws 3012 are also synchronously flipped under the drive of the two synchronous transmission assemblies II 500.
