Description

Technical Field

[0001] This invention relates to the field of battery module manufacturing technology, specifically to a battery module hoisting fixture and hoisting method. Background Technology

[0002] The pressure-holding hoisting of lithium iron phosphate modules into the box involves using specially designed hoisting clamps to lift the modules into the box.

[0003] Existing methods for lifting modules into the enclosure mostly involve manually using tools to hook onto the circular holes on the module before lifting, transporting, and placing it into the enclosure. This method not only carries the risk of the battery falling off, but the friction between the metal hook and the product can also damage it. More importantly, directly lifting the module into the enclosure with a hook results in a lack of end-face compression, making it impossible to maintain pressure throughout the process. This leads to instability in the module's length dimension, and this type of lifting equipment cannot meet the requirement that the length of a specific module must remain unchanged during enclosure placement. Summary of the Invention

[0004] The purpose of this invention is to provide a battery module hoisting fixture and hoisting method to solve the problems of battery membrane assembly falling off and pressure not being maintained in the existing hoisting methods.

[0005] To achieve the above objectives, the present invention is implemented using the following technical solution:

[0006] In a first aspect, this application discloses a battery module hoisting fixture, comprising:

[0007] 1. A battery module lifting fixture, characterized in that it comprises:

[0008] Main framework;

[0009] A suction cup device connected to the bottom surface of the main frame;

[0010] A compression locking mechanism is connected to the bottom surface of the main frame and located on both sides of the suction cup device. The compression locking mechanism is used to compress the battery module to a certain size and maintain pressure on the battery module.

[0011] The bottom support fixture is detachably connected to the main frame via a bottom support fixture connector, and a gripping and lifting space for fixing the battery module is formed between the bottom support fixture and the suction cup device.

[0012] A top locking mechanism is connected to the main frame to fix the bottom support fixture after the bottom support fixture and the main frame are connected.

[0013] The compression locking mechanism includes a driving component, a side guide rail, and a connecting pressure plate. The side guide rail is fixed to the end of the main frame along the length of the suction cup device.

[0014] The driving component is connected to the end of the main frame, and the output end of the driving component is connected to the connecting pressure plate to drive the connecting pressure plate to move.

[0015] The top locking mechanism includes a baffle, a pressure plate connected to the top end of the baffle, and a locking buckle connected to the bottom surface of the pressure plate. The locking buckle is located on one side of the baffle.

[0016] The bottom support fixture connector and the bottom support fixture are fixedly connected, and a slot is provided on one side wall of the bottom support fixture connector;

[0018] Furthermore, the compression locking mechanisms on both sides are symmetrically arranged about the centerline of the suction cup device along its length.

[0019] The length direction of the bottom support fixture is the same as that of the suction cup device. There are two bottom support fixtures, which are symmetrically arranged along the center line of the width direction of the suction cup device.

[0020] Furthermore, the connecting pressure plate has a contoured boss and a contoured groove on the side near the grasping and lifting space, and the contoured boss and the contoured groove are fitted into the end plate of the battery module.

[0021] Furthermore, the driving component also includes a locking knob and a pressing handle rotatably connected to the end of the main frame along the length of the suction cup device. A threaded sleeve is threaded onto the pressing handle, and the threaded sleeve is connected to the connecting pressure plate so that the connecting pressure plate moves when the pressing handle is rotated.

[0022] The locking knob is connected to the squeezing handle, and the locking knob locks the squeezing handle.

[0023] Furthermore, the main frame is also equipped with an infrared ranging device and a proximity switch. The infrared ranging device and proximity switch are used to detect the length of the battery module and send a reminder signal when the length of the battery module meets the set value.

[0024] Furthermore, a guide positioning pin is fixed on the pressure plate, and the guide positioning pin is inserted and connected to the main frame so that the baffle can be raised and lowered relative to the main frame.

[0025] The top locking mechanism also includes an elbow clamp handle and an elbow clamp pressure head. The elbow clamp handle is hinged to the main frame, and the elbow clamp pressure head is located at the output end of the elbow clamp handle.

[0047] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0048] It should be noted that in the description of this invention, the terms "front," "rear," "left," "right," "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are used only for the convenience of describing the invention and do not require the invention to be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on the invention. The terms "front," "rear," "left," "right," "upper," and "lower" used in the description of this invention refer to the directions shown in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0049] like Figures 1 to 12 As shown, this invention discloses a battery module lifting fixture, including a main frame, a bottom support fixture, a suction cup device connected to the bottom surface of the main frame, and a compression locking mechanism connected to the bottom surface of the main frame and located on both sides of the suction cup device. The compression locking mechanism is used to compress the battery module to a certain size and maintain pressure on the battery module. The bottom support fixture is detachably connected to the main frame through a bottom support fixture connector, and a gripping and lifting space for fixing the battery module is formed between the bottom support fixture and the suction cup device. The top locking mechanism is connected to the main frame to fix the bottom support fixture after the support fixture and the main frame are connected.

[0050] The lifting fixture of this application can effectively grasp the battery module through the gripping and lifting space formed by the suction cup device at the top and the bottom support fixture at the bottom, ensuring the stability of the battery module during the transfer process and preventing the battery module from falling. Through the compression and locking mechanism connected to both sides of the suction cup device, the action of the compression and locking mechanism on both sides can compress and maintain pressure on the battery module in the gripping and lifting space, ensuring that the size of the battery module does not change during the transfer process, and ensuring the smooth packing of the battery module in the subsequent process.

[0051] The suction cup device of this application can be in the form of a sponge suction cup 16, which can ensure the suction effect on the battery module.

[0052] In a further embodiment, the compression locking mechanisms on both sides are symmetrically arranged about the centerline of the suction cup device along its length; the centers of the compression locking mechanisms on both sides can be on the same axis to ensure the compression effect on the battery module when the compression locking mechanisms are working.

[0053] The bottom support fixture has the same length direction as the suction cup device. There are two bottom support fixtures, symmetrically arranged along the center line of the suction cup device's width direction. This design, with one bottom support fixture on each of the lower two sides, ensures stable support for the battery module.

[0054] The combined action of the compression and locking mechanisms on the left and right sides of the two bottom support fixtures at the front and rear, and the sponge suction cups on the top, ensures the stability of the battery module during transportation, eliminating the risk of the battery module falling. On the other hand, it can compress and maintain pressure on the battery module, maintaining pressure throughout the transportation and boxing process.

[0055] The lifting fixture of this application will be described below through a specific embodiment.

[0056] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it mainly includes a left-side extrusion locking mechanism 2 and a right-side extrusion locking mechanism 3 for extruding the end face of the module, a bottom support fixture 10 and a bottom support fixture 11 for supporting the bottom of the module, a top locking mechanism 1 for locking the bottom support fixture 10 and the bottom support fixture 11, a main frame connecting the various mechanisms, and a sponge suction cup 16 for adsorbing the module.

[0057] The structure of the main frame is as follows Figures 1 to 4 As shown, it includes parallel crossbeams a24 and b25, and multiple longitudinal beams are connected between crossbeams a24 and b25 to form a frame structure. The left and right ends of the frame structure are also provided with connecting end plates to form a main frame with stable structural strength.

[0058] like Figure 1 As shown, the length direction of the main frame is left-right, and the sponge suction cup 16 is set on the bottom surface of the main frame, with the same arrangement direction as the main frame. The sponge suction cup 16 is fixedly connected to the main frame through connectors a26, b27, c28 and d29 to ensure the stable connection of the sponge suction cup 16.

[0059] The top surface of the main frame is equipped with lifting rings 19, 20, 21, 22, and 23 for hoisting. The installation of these lifting rings provides a hoisting working method.

[0060] The bottom surface of the main frame is also provided with module guide positioning pins 8 and 9 for guiding and positioning during hoisting, and tooling guide positioning pins 6 and 7 for guiding and positioning when entering the box.

[0061] The module guide positioning pin is located inside the tooling guide positioning pin, and the length of the module guide positioning pin is less than the length of the tooling guide positioning pin. During hoisting, the clamp moves towards the tray where the battery module is placed, and the module guide positioning pins 8 and 9 are inserted into the positioning holes of the tray. Because the tooling guide positioning pin is located outside the module guide positioning pin, it will not interfere with the tray during insertion. When placing the module into the box, the tooling guide positioning pins at both ends are inserted into the holes on the box body for positioning. Because the tooling guide positioning pin is relatively long, the module guide positioning pin does not contact the box body when it is inserted into the hole on the box body, and there is no interference between them.

[0062] The bottom of the main frame is also equipped with a proximity switch 4 for detecting when the action is in place, an infrared ranging device 5 for detecting the length of the product, and an electrical connector 18 for connecting external devices. Both the proximity switch 4 and the infrared ranging device 5 are connected to a controller, which is also connected to a buzzer and a display. The display shows the length of the battery module measured by the infrared ranging device 5. The proximity switch 4 can control the left compression locking mechanism 2 and / or the right compression locking mechanism 3 to stop working via the controller. Specifically, when the battery module is compressed to a set pressure range, the left compression locking mechanism 2 and / or the right compression locking mechanism 3 are stopped to ensure that the battery module maintains pressure within the set pressure range.

[0063] Figure 7 , Figure 8 The left-side compression locking mechanism 2 mainly includes a left-side compression handle 201 and a left-side compression bearing 203 for rotational locking, which are locked by a left-side locking knob 202 to prevent rotation, and left-side guide rails 204a, 205b, 206a, and 207b for guiding movement.

[0064] Specifically, left guide rails 204a and 205b are fixed to the ends of the main frame along the length of the suction cup device. Left slider 206a is slidably connected to left guide rail 204a, and left slider 207b is slidably connected to left guide rail 205b. A connecting pressure plate is connected between the bottom surfaces of left sliders 206a and 207b. The left extrusion handle 201 is rotatably connected to the main frame via a left extrusion bearing 203. A threaded sleeve is threaded onto the left extrusion handle 201, and the sleeve is connected to the connecting pressure plate. The connecting pressure plate can move when the left extrusion handle 201 rotates. A left locking knob 202 is connected to the left extrusion handle 201 and is used to lock the left extrusion handle 201.

[0065] like Figure 7As shown, two connecting blocks are connected to the side of the connecting plate away from the left-side pressing handle 201. The working surfaces of the two connecting blocks are flush to ensure the effective action on the battery module. The right-side connecting block is provided with a left-side contoured boss a208, a left-side contoured boss b209, a left-side contoured groove a212, and a left-side contoured groove b213. The left-side connecting block is provided with a left-side contoured boss c210, a left-side contoured boss d211, a left-side contoured groove c214, and a left-side contoured groove d215.

[0066] The contoured bosses and grooves can engage with the protrusions and grooves on the battery module end plate, ensuring a secure fit. Two connecting blocks on each side apply pressure to the battery module, ensuring even pressure distribution.

[0067] Figure 9 , Figure 10 The right-side compression locking mechanism 3, similarly includes a right-side compression handle 301 and a right-side compression bearing 303 for rotational locking, which are locked by a right-side locking knob 302 to prevent rotation. It also includes right-side guide rails 304 and 305, a right-side slider 306, and a right-side slider 307 for guiding movement. The right-side compression locking mechanism 3 has the same structure as the left-side compression mechanism 2, and will not be described again in this application.

[0068] Figure 5 , Figure 6 The top clamping mechanism 1 has two parts, one on the left and one on the right, as shown in the illustration. This application illustrates one end only. It mainly includes an elbow clamp handle 101, an elbow clamp pressure head 102, pressure plate a104, and pressure plate b105 for downward pressure limiting, and a baffle 103, locking buckle a112, and locking buckle b113 for side limiting. The pressure-holding box insertion method of this invention achieves pressure-holding box insertion of the module by adsorbing the upper surface of the module, squeezing the end face of the module, and supporting the bottom surface of the module.

[0069] Furthermore, pressure plate a104 and pressure plate b105 are connected to the front and rear ends of the top surface of the baffle, locking buckle a112 is connected to the bottom surface of pressure plate a104, and locking buckle b113 is connected to the bottom surface of pressure plate b105.

[0070] Locking buckles a112 and b113 are both located on one side of baffle 103, and an installation space is formed between the locking buckles and the baffle for installing the bottom support tooling connector.

[0071] The bottom support fixture connector (bottom support fixture connector a110 and bottom support fixture connector b111) is fixedly connected to the bottom support fixture, and a slot is provided on one side wall of the bottom support fixture connector.

[0072] When the bottom support tooling connector is connected to the main frame, such as Figure 5 and Figure 6 As shown, the bottom support fixture connector is located within the installation space. The slot of the bottom support fixture connector engages with the locking buckle. The side wall of the bottom support fixture connector away from the slot is connected to the baffle. The top surface of the bottom support fixture connector is connected to the pressure plate, and the bottom surface is connected to the main frame. The connection stability of the bottom support fixture a10 and the bottom support fixture b11 is ensured by limiting the position in the upper, lower, left, and right directions.

[0073] The pressure plates a104 and b105 are also fixed with guide positioning pins 106a, b107, c108, and d109. These guide positioning pins are plugged into the main frame to allow the baffle connected to the pressure plates to rise and fall relative to the main frame. The top locking mechanism also includes an elbow clamp handle 101 and an elbow clamp pressure head 102. The elbow clamp handle 101 is hinged to the main frame, and the elbow clamp pressure head 102 is located at the output end of the elbow clamp handle 101. The elbow clamp handle 101 rotates to press or release the baffle 103 via the elbow clamp pressure head. Springs can be installed between the guide positioning pins of pressure plates a104 and b105 and the insertion holes of the main frame. When the elbow clamp pressure head releases from the baffle 103, it can drive pressure plates a104 and b105 to reset, allowing the baffle 103 to automatically rise even when no force is applied, facilitating the installation and disassembly of the bottom support tooling connectors.

[0074] Based on the lifting fixture of this application, this application also discloses a lifting method, which adopts the battery module lifting fixture of any embodiment of this application, and the method includes:

[0075] The suction cup device is controlled to grasp the battery module. The compression locking mechanism is controlled to compress the battery module to a certain size and maintain pressure on the battery module. The bottom support fixture is installed onto the main frame and fixed by the top locking mechanism and the bottom support fixture connector; after the bottom support fixture is connected, the battery module is located in the grasping and lifting space formed by the bottom support fixture and the suction cup device.

[0076] The lifting fixtures and methods described in this application will be explained below through a specific work process.

[0077] First, manually grasp the handrail, and use the module guide positioning pins 8 and 9 to place the sponge suction cup 16 onto the upper surface of the module. Turn on the external vacuum pump and use the air valve 17 to evacuate the sponge suction cup 16, so that the sponge suction cup 16 is tightly adsorbed onto the upper surface of the module.

[0078] Furthermore, manually rotating the left-side extrusion handle 201 forward drives the left-side extrusion bearing 203, causing the entire left-side extrusion locking mechanism 2 to be extruded towards the module via the left-side sliders a206 and b207 on the left-side guide rails a204 and b205. When the left-side contoured bosses a208, b209, c210, d211, a212, b213, c214, and d215 are embedded in the battery module end plate, as... Figure 12 As shown, stop rotating the left squeeze handle 201, and then manually rotate the left locking knob 202 clockwise to lock the left squeeze bearing 203.

[0079] Furthermore, manually rotating the right-side pressing handle 301 forward drives the right-side pressing bearing 303, causing the entire right-side pressing locking mechanism 3 to press towards the module via the right-side sliders a306 and b307 on the right-side guide rails a304 and b305 until the right-side contouring bosses a308, b309, c310, d311, a312, b313, c314, and d315 are embedded in the module end plate. The infrared ranging device 5 is connected to the external display device via the wiring harness and electrical connector 18. When the display module length reaches the predetermined size, the proximity switch 4 senses that the right-side pressing locking mechanism 3 has reached the desired position and stops rotating the right-side pressing handle 301. Then, manually rotating the right-side locking knob 302 forward locks the right-side pressing bearing 303.

[0080] Furthermore, external equipment is used to hook the lifting rings a19, b20, c21, d22, and e23. After the external equipment slightly lifts the module, the operator manually grasps handles a12 and c13 to insert the bottom support fixture connector a110 into the top locking mechanism 1 and then moves it to the side, so that the bottom support fixture connector 110 engages with the locking buckle a112. At the same time, the operator manually grasps handles c14 and c15 to insert the bottom support fixture connector b111 into the top locking mechanism 1 and then moves it to the side, so that the bottom support fixture connector 111b engages with the locking buckle b113. At this point, the bottom support fixtures a10 and c11 support the bottom surface of the module.

[0081] Furthermore, manually rotating the elbow clamp handle 101 forward causes the elbow clamp pressure head 102 to press down on the baffle 103. The baffle 103 is connected to the pressure plate a104 and pressure plate b105 by bolts. This causes the pressure plate a104 to press down on the bottom support connecting tool connector a110 under the guidance of the guide positioning pins b107 and a106, and the pressure plate b105 to press down on the bottom support connecting tool connector b111 under the guidance of the guide positioning pins c108 and d109. At the same time, the baffle 103 limits the bottom support connecting tool connector a110 and the bottom support connecting tool connector b111 from the side.

[0082] The module capture is now complete.

[0083] Furthermore, the external equipment uses lifting rings to move the module to the top of the housing. The tooling guide pins a6 and b7 work with the positioning holes in the housing to find the accurate position, and then the module is lowered to the appropriate height.

[0084] Furthermore, manually rotating the elbow clamp handle 101 in the opposite direction causes the elbow clamp pressure head 102 to rise upwards. After the baffle 103 loses its downward pressure, the baffle 103 is manually lifted, thereby releasing the unilateral limit of the bottom support connecting tool connector a110 and the bottom support connecting tool connector b111. At the same time, during the lifting of the baffle 103, the pressure plates a104 and b105 are lifted upwards under the guidance of the guide positioning pins a106, b107, c108, and d109, thereby releasing the upper limit of the bottom support connecting tool connector a110 and the bottom support connecting tool connector b111.

[0085] Furthermore, by manually grasping handles a12 and b13, the bottom support connecting fixture connector a110 is moved laterally and the top locking mechanism 1 is pulled out. Simultaneously, by manually grasping handles c14 and d15, the bottom support connecting fixture connector b111 is moved laterally and the top locking mechanism 1 is pulled out. At this point, the bottom support fixtures a10 and b11 are removed from the bottom surface of the module. Then, the external equipment continues to lower the module via the lifting rings. When the module reaches the bottom and is in contact with the housing, the housing and the module end plate are connected and fixed using screws.

[0086] Furthermore, manually rotate the right locking knob 302 in the reverse direction to release the right extrusion bearing 303. Then, manually rotate the right extrusion handle 301 in the reverse direction to drive the right extrusion bearing 303, causing the entire right extrusion locking mechanism 3 to move in the opposite direction to the module via the right sliders a306 and b307 on the right guide rails a304 and b305. At this time, the right contouring bosses a308, b309, c310, and d311, and the right contouring grooves a312, b313, c314, and d315 disengage from the module end plate, thus depressurizing the module end face.

[0087] Furthermore, manually rotate the left locking knob 202 in the reverse direction to release the left extrusion bearing 203. Then, manually rotate the left extrusion handle 201 in the reverse direction to drive the left extrusion bearing 203, causing the entire left extrusion locking mechanism 2 to move in the opposite direction of the module via the left sliders a206 and b207 on the left guide rails a204 and b205. At this time, the left contouring bosses a208, b209, c210, d211, a212, b213, c214, and d215 disengage from the module end plate.

[0088] Furthermore, the external vacuum pump is shut off, and the sponge suction cup 16 detaches from the upper surface of the module after the vacuum is lost. The external equipment, through lifting rings a19, b20, c21, d22, and e23, lifts the pressure-holding hoisting mechanism to completely detach from the module.

[0089] Furthermore, the handrail is manually grasped, and the sponge suction cup 16 is placed onto the upper surface of the next module using module guide positioning pins a8 and b9, and the next module is then lifted into the box under pressure.

[0090] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
