Description

Technical Field

[0001] The present invention relates to the technical field of object handling, and in particular to a device and method for preventing displacement of two objects during a handling process. Background Art

[0002] During the production process, due to different designs of processing procedures, some products will pre-stack two parts during assembly, but the two are not fixed together; then they are transported to the next station for assembly with other parts. This transportation process can easily cause the two pre-stacked parts to shift, and when they are assembled with other parts at the next station, they need to be rearranged, which reduces assembly efficiency.

[0003] For example, a lithium battery pack is assembled from multiple modules, thermal pads, water-cooled plates, explosion-proof valves and other parts; the installation order of the water-cooled plate and the module is as follows: the module is placed on the water-cooled plate fixed by the positioning pins, at which time the two are only in contact but not fixed and locked, and then the module and the water-cooled plate are moved to the lower box of the battery pack through the fixture and installed. At present, due to the non-portability and danger of module transportation, a combination of robots and tooling is often used to achieve this transportation action. Its defects are mainly manifested in:

[0004] 1. The relative position between the water cooling plate and the module cannot be guaranteed to be fixed all the time. Due to the influence of factors such as vibration during the movement of the fixture, the pre-placed positions of the two are easily shifted. After the shift, the positions of the two need to be adjusted again, which reduces the installation efficiency.

[0005] Second, some existing tooling clamps use locating pins to fix the relative position of the two to ensure that there is no offset during movement. This method is only applicable to some modules. There are no effective locating pin holes between some modules and the water cooling plate. In this case, the locating pins cannot be used to fix the two relatively. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a device and method for preventing displacement of two objects during the transportation process, using at least four clamps connected as a whole, forming a symmetrical and synchronous clamping method on the four sides of the four modules and the water-cooling plate, ensuring that the relative positions of the two objects do not change, and converting the reverse force of the modules and the water-cooling plate on each clamp into internal stress to offset each other, thereby preventing the clamp from being pushed in the opposite direction.

[0082] The inventive concept of the present invention is as follows:

[0083] The present invention adopts a layout of a right angle formed by the wedge-shaped pressing members 23 and the pushing blocks 242 on both sides, and the module 5 and the water-cooling plate 6 are pressed tightly under the action of the pressing driving part 24, so as to ensure that the relative position of the module 5 and the water-cooling plate 6 does not change during the movement;

[0084] The design principle adopted by the present invention does not use the positioning pin as a reference, and its application range is wider than that of the clamping device of the water cooling plate and the module fixed by the positioning pin;

[0085] The present invention can be installed on fixtures and other tools as required, and has flexibility;

[0086] The clamps 2 are symmetrically arranged and connected as a whole, and the first actuators 241 on the surrounding areas, for example, when using cylinders, are connected by series air pipes, so that the air pressure of the surrounding cylinders remains uniform, so that the reaction forces exerted on the cylinders become internal forces to offset each other, ensuring that there is no excessive air pressure in a single cylinder that pushes the module to have the opposite effect.

[0087] See also Figures 1 to 8 shown.

[0088] Embodiment 1: used for transporting the water-cooling plate 6 and the module 5 which are pre-placed in relative positions;

[0089] A device for preventing two objects from shifting during a transportation process of the present invention comprises:

[0090] Connect component 1;

[0091] At least four clamping jaws 2 are arranged symmetrically in a rectangular shape and are slidably connected to the connecting component 1 , and all the clamping jaws 2 open and close synchronously.

[0092] All the clamping jaws 2 are arranged symmetrically and connected as a whole through the connecting assembly 1, so that the reaction force received by the clamping jaws 2 when clamping an object is converted into internal stress and offsets each other, so that when the clamping jaws 2 clamp an object, the two objects will not be pushed to move relative to each other and have a counter-effect, and finally the two objects can be clamped synchronously for transportation, and the two objects will not move relative to each other during the transportation process, so that when transporting pre-positioned modules and water-cooling plates, the modules and water-cooling plates will not move relative to each other, so that the subsequent assembly does not need to rearrange the position of the modules and water-cooling plates, thereby improving work efficiency.

[0093] When in use, all the clamping jaws 2 are opened synchronously to release the two objects; and are closed synchronously to clamp the two objects synchronously and then carry them.

[0094] Embodiment 2: Based on Embodiment 1,

[0095] Each of the clamping jaws 2 comprises

[0096] Support seat 21;

[0097] The positioning member 22 is connected to the support seat 21 ; the positioning member 22 is used to position the object so that the pressing member 23 can press the object.

[0098] A pressing member 23, wherein the pressing member 23 is movably connected to the supporting seat 21;

[0099] The pressing driving part 24 is connected to the supporting seat 21 , and the pressing driving part 24 is also connected to the pressing member 23 to drive the pressing member 23 to move.

[0100] The support base 21 includes

[0101] a bottom plate 211,

[0102] a first vertical plate 212, wherein the first vertical plate 212 is fixedly connected to one side of the bottom plate 211;

[0103] A second vertical plate 213 , wherein the second vertical plate 213 is vertically fixedly connected to the first vertical plate 212 , and the bottom end of the second vertical plate 213 is fixedly connected to the bottom plate 211 .

[0104] There are two clamping members 23 and two clamping driving parts 24 on each of the support seats 21; thus, when the four clamping jaws 2 are used to clamp the module 5, there are two clamping points on each side, making the clamping process smoother and not easy to damage the relative position of the module 5 and the water cooling plate 6 during positioning and clamping.

[0105] Each of the pressing driving parts 24 includes a first actuator 241, a pushing block 242, a guide block 243, a return spring 244 and a bolt 245;

[0106] A guide groove 2431 is provided on the front end face of each guide block 243, which guides the sliding of the push block 242 to the left and right, making the movement more precise, thereby ensuring that the position of the force point is more accurate when the clamping module 5 is pressed; each guide block 243 is located in the guide groove 2431 and is provided with an axial hole 2432 that passes through the front and rear end faces, which is used to pass the guide shaft 231, and guides the movement of the clamping member 23, making the movement of the clamping member 23 more precise; in a specific embodiment, there are two axial holes 2432 and two guide shafts 231, and a bushing 246 is sleeved in the axial hole 2432, the bushing is made of plastic, and the clamping member 23 and the push block 242 are made of metal, so that the friction between the guide shaft 231 and the axial hole 2432 can be avoided when the guide shaft 231 slides, that is, the friction between metal and metal is avoided, and the service life of the guide shaft 231 is shortened.

[0107] The rear end face of each clamping member 23 is a wedge-shaped face, and the rear end face of each clamping member 23 is convexly provided with a guide shaft 231; a threaded hole 2311 is provided at the rear end of the guide shaft 231; an insulating sheet 232 is provided at the front end face of each clamping member 23; in a specific implementation, the insulating sheet 232 and the positioning member 22 are both made of non-metallic materials, for example: the insulating sheet 232 is made of POM, and the positioning member 22 is made of polyurethane, to ensure that the clamping jaws 2 are in an insulating state when contacting the module 5, that is, when the clamping member 23 clamps the module 5, the insulating sheet 232 and the side of the module 5 are fitted to achieve insulating contact and avoid safety hazards.

[0108] The second vertical plate 213 and the first vertical plate 212 are respectively fixedly connected with a first actuator 241, and the first actuator 241 is arranged vertically downward;

[0109] The first vertical plate 212 and the second vertical plate 213 are respectively fixedly connected with a guide block 243, and the guide groove 2431 is arranged vertically downward;

[0110] The front end surface of each of the push blocks 242 is a wedge-shaped surface; the bottom end of each of the push blocks 242 is provided with an avoidance groove 2421 upward; the push blocks 242 are fixedly connected to the first actuators 241 one by one; in this embodiment, the first actuators 241 are arranged in a vertical direction, which can reduce the space occupied by the clamp 2 in the horizontal direction, make full use of the space in the height direction, and make the entire device occupy a smaller area. Of course, in other embodiments, the first actuator 241 can also be arranged horizontally and directly fixedly connected to the clamping member 23. This is also possible, but such an arrangement requires sufficient space in the horizontal direction for the first actuator 241 to move, so the horizontal space undoubtedly needs to be larger.

[0111] The guide shaft 231 of each pressing member 23 slides through the shaft hole 2432 one by one, and then is covered with a return spring 244, and finally locked into the threaded hole 2311 with a bolt 245;

[0112] The return spring 244 respectively presses against the rear end surface of the guide block 243 and the bolt 245;

[0113] The avoidance groove 2421 of the pushing block 242 can be slidably sleeved on the guide shaft 2432 up and down;

[0114] The wedge-shaped surface of the pressing member 23 and the wedge-shaped surface of the pushing block 243 are arranged parallel to each other;

[0115] The first vertical plate 212 and the second vertical plate 213 are respectively provided with a receiving groove 214 ; the return spring 244 and the bolt 245 are also respectively located in the receiving groove 214 .

[0116] In a specific embodiment, the first actuator 241 is a cylinder, and the air pipes of each cylinder are connected in series, so that the air pressure of each cylinder is kept uniform and consistent, and the air pressure of a certain cylinder is not higher, so that a certain cylinder pushes the module 5 to have a counter-effect. The bolt 245 is first sleeved with a gasket and then locked into the threaded hole 2311. In the default state, the return spring 244 is in a natural state, one end of which is abutted on the bushing 246 and the other end is abutted on the gasket, giving the pressing member 23 a backward force. The pressing member 23 is in the position of minimum displacement by default, that is, the distance between it and the pushing block 242 is the smallest.

[0117] Principle of use: When in use, the cylinder acts on the push block 242, pushing the push block 242 downward, and the U-shaped avoidance groove 2421 gradually fits into the two guide shafts 231, and the downward displacement gradually increases. The wedge surface of the push block 242 contacts the wedge-shaped back surface of the clamping member 23, gradually pushing the clamping member 23 forward, and the return spring 244 is compressed until the insulating sheet 232 in front of the clamping member 23 presses against the side of the module 5. At this time, there is no gap between the module 5 and the clamping jaw 2, and the water-cooled plate 6 fits with the first L-shaped positioning groove 221 of the positioning member 22, which plays the role of positioning, clamping and supporting the water-cooled plate 6, ensuring that the relative position of the clamping jaw 2 and the module 5 and the water-cooled plate 6 does not change.

[0118] Each of the support seats 21 is provided with a positioning member 22;

[0119] A first L-shaped positioning groove 221 is provided at the top of one end of the positioning member 22; in a specific embodiment, the first L-shaped positioning groove 221 is equal to the thickness of the water-cooling plate 6 at the bottom of the module 5, that is, the vertical depth of the first L-shaped positioning groove 221 is equal to the thickness of the water-cooling plate 6; the water-cooling plate is placed at the bottom of the module in a sheet shape, and the width of the first L-shaped positioning groove 221 is less than the width of the module. The width of the positioning groove supports the four sides of the water-cooling plate. Therefore, the top surface of the positioning member 22 is flush with the bottom surface of the module 5; the bottom surface and side surface of the first L-shaped positioning groove 221 correspond to the bottom surface and side surface of the water-cooling plate 6 respectively.

[0120] The positioning member 22 is fixedly connected to the bottom plate 211 .

[0121] There are four clamping jaws 2, which are arranged in a rectangular shape at the four corners of the module 5 and the water-cooling plate 6, and the two side surfaces corresponding to each corner are clamped synchronously.

[0122] The connection component 1 comprises

[0123] Fixed seat 11,

[0129] The third guide rail 17 includes two third guide rails 17 ; the third guide rail 17 is slidably connected to the third sliders 16 , and each third guide rail 17 includes two third sliders 16 .

[0130] like Figure 2 As shown, Figure 2 Taking the direction shown as an example, the function of the third guide rail 17 is to connect the two clamping jaws 2 in the front-to-back direction into one body; the third slider 16 and the third guide rail 17 are provided for sliding connection, so as to realize that the two clamping jaws 2 in the front-to-back direction are connected into one body without affecting the opening and closing movement of the two clamping jaws 2 in the front-to-back direction;

[0131] The second guide rail 14 connects the two clamping jaws 2 in the left and right directions into a whole, and enables the two clamping jaws 2 to open and close.

[0132] Working principle: The first slider 13 slides along the first slide rail 12 to adjust the coordinate of the clamp 2 in the Y-axis direction. During this process, the third slider 16 slides along the third guide rail 17, so as not to affect the movement of the clamp 2 in the Y-axis direction.

[0133] It also includes an auxiliary clamp 3; the auxiliary clamp 3 is set according to the length requirements of the module 5 and the water-cooling plate 6. If the length is large, the auxiliary clamp 3 can be added for auxiliary support to avoid bending or even breaking of the middle position of the module 5 and the water-cooling plate 6.

[0134] There are two auxiliary clamps 3 ; in a specific embodiment, the two auxiliary clamps 3 are arranged at the middle position of the clamp 2 , corresponding to the middle position of the module 5 and the water cooling plate 6 .

[0135] The auxiliary clamp 3 includes a vertical plate 31 and a horizontal plate 32 connected to each other;

[0136] The horizontal plate 32 is provided with an auxiliary positioning member 33, and the auxiliary positioning member 33 is provided with a second L-shaped positioning groove 331; in a specific embodiment, the second L-shaped positioning groove 331 and the first L-shaped positioning groove 221 are equal to the thickness of the water-cooling plate 6 at the bottom of the module 5, that is, the depth in the vertical direction is equal to the thickness of the water-cooling plate 6, and the width is less than the width of the module, and the width of the positioning groove supports the four sides of the water-cooling plate.

[0158] The first actuator 241 adopts a cylinder, and the pipelines of each cylinder are connected in series to avoid the situation where the cylinder air pressure on a single clamp 2 is too high, which will push the module 5. Multiple cylinders are controlled by one air pipe to ensure that the air pressure of multiple cylinders is balanced. When the module 5 contacts the clamping piece 23, the reaction force generated by the reaction force of each clamp 2 is offset by each other, and the clamp 2 will not be pushed.

[0159] Each cylinder, the first drive motor 41, the second drive motor 44, and the lifting device are connected to a controller, such as a PLC, model: 6ES7515-2AM01-0AB0, for unified control. A control program for the motion trajectory of each gripper 2 is pre-set.

[0160] The controller controls the lifting device to move the device to a tray on which the module 5 and the water-cooling plate 6 are placed; wherein the module 5 and the water-cooling plate 4 on the tray have been pre-calibrated and placed relative to each other, but the two are not fixed;

[0162] After tightening, the controller controls the cylinder in the clamp 2 to move downward, thereby pushing the insulating sheet 232 of the clamping piece 23 to fit the side of the module. When the predetermined clamping position is reached, the controller controls the hoist to lift the device and the module 5 and the water-cooling plate 6 as a whole and transport them to the next process. The entire process is operated by a robot.
