[0001] The present invention relates to a battery tray pressing, milling, positioning and rotating device, and in particular to a battery tray pressing, milling, positioning and rotating device applied in the field of battery tray milling processing. Background Art

[0002] With the promotion of new energy vehicle technology, the research and development and processing of new energy batteries have also increased. When the battery is assembled, the bottom tray will be welded. However, during the welding process, overflow wire drawing and weld scars will inevitably occur, which requires milling to ensure the welding quality of the tray surface. During milling, symmetrically arranged clamping devices are usually used to position the tray. However, the clamping device is arranged on the surface of the tray, which will affect the milling equipment operating on the tray surface, resulting in certain limitations in the milling operation.

[0003] In order to solve the problem of inconvenient milling operation, a milling positioning rotating pallet device in the market adopts a bolt positioning design and has a certain market share.

[0004] The specification of Chinese utility model patent CN202223122537.4 discloses a CNC cylindrical workpiece pressing milling positioning rotating pallet device, which realizes multi-station continuous positioning processing of the inner cavity and outer wall of the cylindrical part through the movement of the CNC rotary table and the movement of the milling cutter of the milling processing center. The rotating pallet is fixedly connected to the CNC rotary table through the positioning plate to realize the integrated linkage of the pallet and the CNC table. The positioning pins installed on the pallet are matched with the positioning holes on the bottom surface of the cylindrical part, and then the inner and outer edges of the bottom end surface of the cylinder are pressed with the pressing plate, and the screws are tightened. The workpiece is fixed by pressing the pressing plate on the inner and outer edges of the workpiece end surface through the cooperation of the pressing plate and the screws. This device can realize the stable clamping and fixing of large-sized cylindrical workpieces with a diameter of more than 1000mm, and ensure the stability and positioning accuracy of the workpiece during the milling operation. The utility model has the characteristics of fast positioning, firm and stable clamping, and is suitable for the CNC milling processing and forming requirements of large-sized cylindrical workpieces.

[0005] The above-mentioned milling positioning rotating pallet device uses a large number of positioning pins when positioning the pallet, and both installation and removal require a certain amount of time, which is not conducive to realizing the automation of pallet positioning. Summary of the invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to realize the automated processing of pallet positioning when the pallet surface is milled, and to ensure the accuracy and stability of positioning.

[0007] In order to solve the above problems, the present invention provides a battery tray pressing, milling, positioning and rotating device, including a rotating bracket, a lifting bracket is installed on the top of the rotating bracket, a recessed groove is provided at the top of the lifting bracket, the inner wall of the recessed groove is connected to an electric telescopic plate through an axis rod, a suction cup unit is hinged at the top of the electric telescopic plate, a servo drive motor is installed on the surface of the lifting bracket, and the servo drive motor is electrically connected to the electric telescopic plate, the output end of the servo drive motor is connected to the end of the axis rod, and a detection unit is installed inside the suction cup unit.

[0008] In the above-mentioned battery pallet clamping, milling, positioning and rotating device, the suction cup design is utilized to eliminate the use of a large number of positioning pins and positioning bolts, thereby simplifying the positioning process during the pallet milling operation. In addition, the servo drive motor, electric telescopic plate and detection unit are utilized to enable the suction cup unit to be separated from the area where the channel notch is located, thereby ensuring the normal adsorption constraint of the suction cup unit on the bottom of the pallet.

[0009] As a further improvement of the present application, the detection unit includes a micro drive motor installed inside the suction cup unit, the output end of the micro drive motor is connected to a rotating ball, a plurality of micro ultrasonic ranging sensors are installed on the surface of the rotating ball, and the micro ultrasonic ranging sensors are all electrically connected to the servo drive motor.

[0010] As a further improvement of the present application, the projection of one of the miniature ultrasonic ranging sensors in the vertical direction is on the same axis as the center of the projection of the rotating ball in the vertical direction, and the remaining miniature ultrasonic ranging sensors are all installed obliquely on the surface of the rotating ball, and the inclination angle is 40°-55°.

[0011] As a further improvement of the present application, the vertical distance between the bottom wall of the recessed groove and the bottom of the electric telescopic plate is greater than half of the cross-sectional width of the electric telescopic plate itself, and the shaft is connected to the inner wall of the recessed groove through a damping shaft.

[0016] To summarize, the present application utilizes the design of the suction cup to eliminate the use of a large number of positioning pins and positioning bolts, thereby simplifying the positioning process during pallet milling operations. In addition, by utilizing a servo drive motor, an electric telescopic plate, and a detection unit, the channel gap at the bottom of the pallet corresponding to the suction cup can be detected, and then the position and length of the electric telescopic plate can be deflected, so that the suction cup unit can be separated from the area where the channel gap is located, thereby ensuring the normal adsorption constraint of the suction cup unit on the bottom of the pallet. In addition, with the help of the pull rope, magnetic slider, silicone ring, and outward-expanding suction cup cover, the suction cup unit can reduce the adsorption diameter when adjusting to leave the area where the channel gap is located, thereby accelerating the adjustment.

[0031] The following describes two implementation modes of the present application in detail with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-8 A battery tray pressing, milling, positioning and rotating device is shown, which includes a rotating bracket 1, a lifting bracket 2 is installed on the top of the rotating bracket 1, a recessed groove is provided on the top of the lifting bracket 2, the inner wall of the recessed groove is connected to an electric telescopic plate 5 through an axis rod, a suction cup unit 4 is hinged on the top of the electric telescopic plate 5, a servo drive motor 3 is installed on the surface of the lifting bracket 2, and the servo drive motor 3 is electrically connected to the electric telescopic plate 5, the output end of the servo drive motor 3 is connected to the end of the axis rod, and a detection unit 6 is installed inside the suction cup unit 4.

[0034] Specifically, the bottom end of the rotating bracket 1 in the device can be connected to the output end of the rotating driving device, thereby driving the lifting bracket 2 and the suction cup unit 4 above to rotate synchronously, driving the adsorbed and connected tray to rotate. In addition, the design of the suction cup can ensure the adsorption and positioning of the tray, and can also avoid the use of a large number of positioning pins. However, when the tray serves the battery, a channel is opened at the bottom of the tray to ensure the heat dissipation and drainage of the battery. Therefore, when the suction cup is working, if the suction cup is located below the channel, the adsorption and connection between the suction cup and the tray surface will be destroyed. Therefore, an improvement is made for this situation.

[0035] The detection unit 6 can be used to determine whether the suction cup unit 4 is located below the channel at the bottom of the tray. When it is determined that the suction cup unit 4 is located below the channel, the servo drive motor 3 drives the shaft rod to rotate, and then drives the electric telescopic plate 5 sleeved on the surface of the shaft rod to deflect inside the recessed groove. At this time, the suction cup unit 4 that was originally vertically attached to the bottom of the tray tilts, and part of it is squeezed and contacted with the bottom of the tray to bend and deform. At the same time, the detection unit 6 continues to detect. When there is no longer a channel on the bottom surface of the tray corresponding to the suction cup unit 4, the electric telescopic plate 5 is started to give squeezing support to the suction cup unit 4 until the suction cup unit 4 is adsorbed on the bottom of the tray 4 at a position deviating from the channel, thereby forming an effective adsorption process. In this way, the suction cup unit 4 can be prevented from being affected by the recessed channel set inside the tray when adsorbing the tray, thereby ensuring the stability of the tray positioning effect.

[0036] The detection unit 6 includes a micro drive motor 61 installed inside the suction cup unit 4. The output end of the micro drive motor 61 is connected to a rotating ball 62. A plurality of micro ultrasonic ranging sensors 63 are installed on the surface of the rotating ball 62. The micro ultrasonic ranging sensors 63 are all electrically connected to the servo drive motor 3.

[0037] The vertical projection of one of the micro ultrasonic ranging sensors 63 is on the same axis as the center of the vertical projection of the rotating ball 62 , and the remaining micro ultrasonic ranging sensors 63 are all installed obliquely on the surface of the rotating ball 62 , and the inclination angle is 40°-55°.

[0038] Specifically, the micro drive motor 61 is started to drive the rotating ball 62 to rotate, thereby driving a plurality of micro ultrasonic distance measuring sensors 63 installed on the surface of the rotating ball 62 to rotate synchronously, and ultrasonic distance measurement detection is performed on the upper space corresponding to the suction cup unit 4. Since the ultrasonic distance values ​​corresponding to the channel area and the solid area are different, it can be used to determine whether it is necessary to start the servo drive motor 3 and the electric telescopic plate 5 to adjust the position of the suction cup unit 4 at the bottom of the tray;

[0039] In addition, the micro ultrasonic ranging sensors 63 are arranged in such a way that one of them is at the tangent point at the top of the rotating ball 62, and the remaining micro ultrasonic ranging sensors 63 surround the periphery of the micro ultrasonic ranging sensor 63 at the tangent point. Therefore, the micro ultrasonic ranging sensor 63 at the tangent point can detect whether there is a channel directly above the rotating ball 62. The micro ultrasonic ranging sensors 63 arranged in a surrounding manner are used to detect whether there is a channel between directly above the rotating ball 62 and the edge of the suction cup unit 4, thereby improving the comprehensiveness of the channel detection.

[0040] The vertical distance between the bottom wall of the concave groove and the bottom of the electric telescopic plate 5 is greater than half of the cross-sectional width of the electric telescopic plate 5 itself, and the shaft is connected to the inner wall of the concave groove through the damping shaft.

[0041] Specifically, the distance between the bottom wall of the recessed groove and the electric telescopic plate 5 ensures that the electric telescopic plate 5 will not be blocked by the bottom wall of the recessed groove when rotating. At the same time, the design of the damping shaft can avoid the rotation of the electric telescopic plate 5 in an unnecessary state (that is, when the servo drive motor 3 is not started).

[0042] The rotating bracket 1 and the lifting bracket 2 are both retractable in design.

[0043] Specifically, the rotating bracket 1 is retractable in the vertical direction, thereby being used to assist in adjusting the milling operation height of the pallet, while the lifting bracket 2 is retractable in the horizontal direction, thereby enabling the device to be suitable for the clamping and limiting processing of pallets of different lengths.

[0044] Second implementation method:

[0045] Figure 9-12 , wherein the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment are described below. The difference between the second embodiment and the first embodiment is that the suction cup unit 4 includes a base suction cup 41, a silicone ring 44 is installed at the bottom of the base suction cup 41, a plurality of outer support rods 42 are installed on the outer surface of the base suction cup 41, an outward-expanding suction cup cover 45 is connected to the surface of the silicone ring 44, a pull rope 43 corresponding to the outer support rod 42 is connected to the bottom end of the surface of the outward-expanding suction cup cover 45, and the tail end of the pull rope 43 extends to the inside of the outer support rod 42.

[0046] The tail end of the pull rope 43 is connected to a magnetic slider 431 slidably connected to the inside of the outer support rod 42 . An electromagnetic block is installed inside the outer support rod 42 , and there is a magnetic attraction between the electromagnetic block and the magnetic slider 431 .

[0047] The pull rope 43 is made of non-elastic material, and the outward-expanding suction cup cover 45 is made of elastic material, and the elastic force of the outward-expanding suction cup cover 45 itself is greater than the sum of the gravity values ​​of the pull rope 43 and the magnetic slider 431 .

[0048] Specifically, in order to ensure the lifting and support of the tray by the suction cup unit 4 and the adsorption and restraining effect, the diameter of the suction cup unit 4 is relatively large, which makes it difficult to adjust the suction cup unit 4 to leave the area where the channel is located when the electric telescopic plate 5 is deflected. Therefore, a suction cup unit that can reduce the adsorption area is designed to solve this problem;

[0049] When the electric telescopic plate 5 deflects following the output torque of the servo drive motor 3, the electromagnetic block is started, and the magnetic attraction between the electromagnetic block and the magnetic slider 431 is utilized to drive the pull rope 43 to climb along the inside of the outer support rod 42, thereby driving the bottom end of the outer expansion suction cup cover 45 to tilt outward and buckle inward, thereby exposing the silicone ring 44;

[0050] At this time, the overall diameter of the suction cup unit 4 is reduced, the effective adsorption area is the bottom area of ​​the base suction cup 41, and the adsorption surface is the silicone ring 44, which can reduce the time for the suction cup unit 4 to adjust and leave the channel area.

[0051] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
