Description

[0002] The power battery is the electrical energy supply device for electric vehicles and consists of a power battery case and a battery pack housed within it. To ensure the structural strength of the power battery and protect the battery pack, a battery case is installed outside the power battery. The battery case consists of an upper case and a lower case. The lower case is the primary load-bearing component and requires sufficient strength and rigidity, while the upper case primarily protects the battery module.

[0003] A water nozzle needs to be installed at the inlet of the cooling channel on the lower box body to circulate coolant to maintain the battery pack at a suitable operating temperature, thereby improving the performance and life of the motor; in addition, an explosion-proof valve needs to be installed on the lower box body. The explosion-proof valve can release gas when the internal pressure of the battery rises abnormally to avoid the risk of battery explosion.

[0004] The existing installation of the water faucet and explosion-proof valve on the lower case is mainly done manually after the lower case is fixed with a clamp. This manual installation is inefficient and cannot ensure that workers' installation operations meet production requirements.

DETAILED DESCRIPTION

[0028] The present invention provides an assembly machine for a water nozzle 44 and an explosion-proof valve 43 for a power battery lower case 42. To clarify the objectives, technical solutions, and effects of the present invention, the present invention is further described below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are intended only to illustrate the present invention and are not intended to limit its scope.

[0029] See also Figures 1-8The present invention provides a water faucet and explosion-proof valve assembly machine for the lower box of a power battery, comprising a platform 11, a stand 2 arranged on the platform 11, a water faucet installation mechanism 3 arranged on the top of the stand 2, and an explosion-proof valve pressing mechanism 5 arranged at the bottom of the stand 2. The rear side of the stand 2 is provided with a clamping station 41 for clamping the lower box 42, and the clamping station 41 is provided with a clamp for fixing the lower box 42, so that the lower box 42 is in an upright state after clamping; the water faucet installation mechanism 3 includes a bracket 31, a transverse slide 32 slidable left and right on the bracket 31, a first sliding drive mechanism 33 for driving the transverse slide 32 to move left and right, a vertical slide 34 slidable up and down on the transverse slide 32, a tightening mechanism 35 provided on the vertical slide 34, and a second sliding drive mechanism 36 for driving the vertical slide 34 to move up and down, and the tightening mechanism 35 is used to tighten the water faucet 44 on the lower box 42. The faucet installation mechanism 3, the explosion-proof valve pressing mechanism 5 and the clamp are all controlled by the electric control box.

[0030] During assembly, the staff first places the lower box body 42 upright on the stand 2, and clamps the lower box body 42. At this time, the two water spout installation positions of the lower box body 42 are located at the top of the lower box body 42 and the two water spout installation positions are spaced apart on the left and right. The explosion-proof valve 43 installation position of the lower box body 42 is located at the bottom of the lower box body 42. Then the staff installs a water spout 44 on the two water spout installation positions of the lower box body 42. At this time, the water spout 44 is in an untightened state. Then, an explosion-proof valve 43 is placed on the explosion-proof valve pressing mechanism 5. Then the water spout installation mechanism 3 and the explosion-proof valve pressing mechanism 5 work synchronously. The tightening mechanism 35 in the water spout installation mechanism 3 is located directly above the left water spout 44 in the initial state. The second sliding drive mechanism 36 drives the vertical slide 34 and the tightening mechanism 35 to descend. The tightening mechanism 35 cooperates with the water spout 44 on the left, and then the tightening mechanism 35 automatically tightens the left water spout 44, which can be understood as tightening When the tightening mechanism 35 detects that the actual tightening torque or angle reaches the preset value, it indicates that the water nozzle 44 is successfully installed, and the tightening mechanism 35 will stop working. Then the second sliding drive mechanism 36 drives the vertical slide 34 and the tightening mechanism 35 to rise, and the first sliding drive mechanism 33 drives the transverse slide 32 to move to the right until the tightening mechanism 35 is directly above the right water nozzle 44. Similarly, the second sliding drive mechanism 36 drives the vertical slide 34 and the tightening mechanism 35 to descend, and the tightening mechanism 35 cooperates with the water nozzle 44 located on the left, and then the tightening mechanism 35 automatically tightens the right water nozzle 44, and finally the tightening mechanism 35 rises and moves to the left to its initial position; at the same time, the explosion-proof valve pressing mechanism 5 lifts the explosion-proof valve 43 upward, and automatically presses the explosion-proof valve 43 into the explosion-proof valve 43 installation position of the lower box body 42; finally, the clamp loosens the lower box body 42, and the staff removes the lower box body 42 with the water nozzle 44 and the explosion-proof valve 43.

[0031] Compared with the existing technology, the faucet and explosion-proof valve assembly machine independently developed by the present invention can replace manual installation of the faucet 44 and the explosion-proof valve 43. On the one hand, it ensures the standardization and consistency of each assembly part, reduces installation errors in manual operation, eliminates unnecessary variations, and thus improves the stability of product quality. On the other hand, it can reduce labor costs, requires less maintenance and operation management, and further saves the company's operating costs; in addition, the faucet 44 and explosion-proof valve 43 assembly machine cleverly uses a clamp to upright and fix the lower box body 42, meeting the requirements of the faucet installation mechanism 3 and the explosion-proof valve pressing mechanism 5 to simultaneously install the faucet 44 and the explosion-proof valve 43, greatly improving the assembly efficiency.

[0032] Specifically, the stand 2 includes a horizontally arranged bottom plate 21, a vertical plate 22 vertically arranged on the bottom plate 21, side plates 23 vertically arranged on both sides of the vertical plate 22, and a top plate 24 horizontally arranged on the top of the vertical plate 22 and the side plates 23. The side plates 23 not only play a pulling and stabilizing role on the vertical plate 22 to ensure that the vertical plate 22 always remains in a vertical state, but also increase the installation area of ​​the top plate 24 to ensure that the top plate 24 is installed stably.

[0033] Specifically, the explosion-proof valve pressing mechanism 5 includes a first mounting plate 51 fixed to the bottom surface of the base plate 21, a second mounting plate 52 arranged at the bottom of the first mounting plate 51, a pressing cylinder 53 arranged vertically upward on the second mounting plate 52, a transition plate 54 connected to the end of the piston rod of the pressing cylinder 53, and a placement seat 55 arranged on the transition plate 54. The placement seat 55 is used to load the explosion-proof valve 43. The first mounting plate 51 is provided with a hollow area 56 for the transition plate 54 to move; the base plate 21 is provided with a first avoidance opening 57 for avoiding the placement seat 55.

[0034] When assembling the explosion-proof valve 43, first place the explosion-proof valve 43 on the placement seat 55, align the explosion-proof valve 43 with the explosion-proof valve installation port of the lower box body 42, then extend the piston rod of the press-fitting cylinder 53 upward, driving the explosion-proof valve 43 to press the bottom of the lower box body 42, and the multiple blocks on the explosion-proof valve 43 are snap-connected with the explosion-proof valve installation port, and the assembly is completed. The explosion-proof valve is quickly installed.

[0035] Preferably, a detection guide rod 61 pointing vertically downward is provided on the transition plate 54, and the detection guide rod 61 is slidably connected to the linear bearing 62 on the second mounting plate 52. Through the guiding effect of the linear bearing 62 and the detection guide rod 61, not only can the correct movement direction of the explosion-proof valve 43 be ensured, the piston rod of the press-fitting cylinder 53 can be avoided from being subjected to shear force, and the piston rod can be prevented from being deformed due to shear force, but the position of the placement seat 55 can also be indirectly monitored with the help of the detection guide rod 61.

[0036] Specifically, a trigger plate 63 is provided at the bottom end of the detection guide rod 61, and a sensor bracket 64 is provided at the bottom of the stand 2. A first proximity sensor 65 and a second proximity sensor 66 located below the first proximity sensor 65 are mounted on the sensor bracket 64. The trigger plate 63 can trigger the first proximity sensor 65 to detect whether the placement seat 55 has risen to the set press-fitting position; the trigger plate 63 can also trigger the second proximity sensor 66 to detect whether the placement seat 55 has returned to its original position. The first and second proximity sensors 65, 66 provide feedback signals to the electrical control box, thereby controlling the movement of the press-fitting cylinder 53.

[0037] In addition, a mounting seat 67 is provided on the side of the second mounting plate 52, and a displacement sensor 68 is provided on the mounting seat 67 for detecting the up and down displacement data of the trigger piece 63. The displacement sensor 68 can detect and record the displacement stroke and speed of the placement seat 55, which is of great significance for the subsequent optimization and improvement of the pressing force and the pressing of the explosion-proof valve 43 into place.

[0038] Since the lower box body 42 is a thin-walled structure at the explosion-proof valve installation port, and the pressing force output by the pressing cylinder 53 on the explosion-proof valve 43 is relatively large, in order to improve the problems of deformation and vibration of the explosion-proof valve installation port during pressing, a transfer and pressing mechanism 7 for pressing the explosion-proof valve 43 installation port of the lower box body 42 downward is provided on the bottom plate 21. The transfer and pressing mechanism 7 includes a support slide 71 that can be slid forward and backward on the bottom plate 21, a third sliding drive mechanism 72 for driving the support slide 71 to move, an adapter support 73 fixed on the support slide 71, a pressure arm 74 pivotally connected to the adapter support 73, and a pressure block 75 provided at the head of the pressure arm 74; a pressing drive cylinder 76 for driving the tail of the pressure arm 74 is provided on the support slide 71, and a support cylinder 77 for upwardly supporting the tail of the pressure arm 74 is provided on the support slide 71; a second avoidance opening 78 for the pressure arm 74 to pass through is opened on the vertical plate 22.

[0039] In the non-working state, the transfer and pressing mechanism 7 is hidden behind the vertical plate 22. The transfer and pressing mechanism 7 starts working in advance of the explosion-proof valve pressing mechanism 5. The third sliding drive mechanism 72 drives the support slide 71 to move toward the vertical plate 22, driving the pressing arm 74 to pass through the second avoidance opening 78 and extend into the inner cavity of the lower box body 42. Then, the pressing drive cylinder 76 drives the pressing arm 74 to swing, so that the pressure block 75 on the head of the pressing arm 74 presses the explosion-proof valve installation part of the lower box body 42. In addition, the support cylinder 77 adopts a pneumatic forward support cylinder, and the pneumatic floating support supports the tail of the pressing arm 74, thereby enhancing the stability of the pressing arm 74. It can absorb part of the pressing force, thereby reducing the damage to the piston rod of the pressing drive cylinder 76 caused by the pressing force, and improving the service life of the pressing drive cylinder 76. When the explosion-proof valve pressing mechanism 5 installs the explosion-proof valve 43, since the clamping force provided by the clamp is in the front-to-back direction, and the explosion-proof valve pressing mechanism 5 provides a vertical upward pressing force, the pressing block 75 of the transfer and clamping mechanism 7 overcomes the impact of the pressing force on the lower box body 42, thereby avoiding the lower box body 42 being driven to shift and damage the clamp and deformation of the lower box body 42.

[0040] Specifically, the clamp includes a plurality of support blocks 80 provided on the stand 2 and a plurality of clamps 84 for pressing the lower box 42 against the support blocks 80. Some of the support blocks 80 are provided with positioning pins 83, which cooperate with positioning holes on the lower box 42 to accurately pre-install the lower box 42 on the stand 2. Because the lower box 42 is in an unstable state before the clamp is clamped, in order to better pre-fix the lower box 42, the riser 22 is provided with two clamping assemblies 81 for fixing the two sides of the lower box 42. Each clamping assembly 81 includes a limit seat 811, a movable limit block 812 pivotally connected to the limit seat 811, and a spring plunger 813 for providing the movable limit block 812 with a tendency to clamp the movement of the lower box 42. After the upper and lower boxes 42 are installed, the spring plunger 813 provides a clamping force on the movable limit block 812, so that the movable limit block 812 contacts and fixes the two sides of the lower box 42, keeping its position stable. The spring plunger 813 uses elastic force to keep the movable limit block 812 always in contact with the lower box 42 and enhance the clamping effect.

[0041] Furthermore, the vertical plate 22 is provided with a plurality of anti-foolproof blocks 82 that limit the placement position of the lower box 42. Due to the provision of the anti-foolproof blocks 82, the staff is forced to place the lower box 42 in the correct position, which effectively reminds and prevents the staff from installing the lower box 42 upside down. The clamp 84 includes a lever cylinder 841 and a pressure head 842 provided on the output end of the lever cylinder 841. When clamping the lower box 42, the piston rod of the lever cylinder 841 extends, causing the pressure head 842 to rotate and press on the lower box 42. When disassembling the lower box 42, the piston rod of the lever cylinder 841 retracts, and the pressure head 842 tilts up, causing the pressure head 842 to release the lower box 42. At the same time, the pressure block 75 swings to a position that does not affect the removal of the workpiece from the vertical plate 22.

[0042] Specifically, the tightening mechanism 35 includes a servo-type tightener 351, a hexagonal screwdriver 352 mounted at the output of the servo-type tightener 351, and a controller 353 for controlling the servo-type tightener 351. The servo-type tightener 351 can be purchased directly from the market, and its specific structure is not described in detail here. The controller 353 is configured to set the required tightening parameters, such as tightening torque, angle, or tensile force. The hexagonal screwdriver 352 engages the hexagonal portion of the faucet 44, and the servo-type tightener 351 activates the faucet 44 to tighten it. The servo-type tightener can precisely control the tightening torque or angle, improving assembly quality and production efficiency. Furthermore, through real-time monitoring by sensors and feedback to the controller 353, abnormalities during the tightening process can be detected and timely adjustments can be made to ensure the stability of assembly quality.

[0043] In order to accurately monitor the installation status of the water spout 44 and the explosion-proof valve 43 and prevent the water spout 44 and the explosion-proof valve 43 from being missing, two first sensors 91 are provided on the vertical plate 22, and the two first sensors 91 are respectively used to detect whether the water spouts 44 are installed at the two water spout installation positions of the lower box 42; the vertical plate 22 is provided with a second sensor 92 for sensing whether the explosion-proof valve 43 is installed on the lower box 42; the vertical plate 22 is provided with a third sensor 93 for sensing whether the explosion-proof valve 43 is loaded on the placement seat 55, and a plurality of fourth sensors 94 for detecting whether the lower box 42 is clamped in place.

[0044] Preferably, the bracket 31 is provided with a first limit block 95 and a second limit block 96, respectively located on both sides of the transverse slide 32. The first limit block 95 and the second limit block 96 are both provided with a limit head 97 and a hydraulic buffer 98. The limit head 97 and the hydraulic buffer 98 can adjust the left and right transverse movement of the transverse slide 32 to overcome the movement inertia of the transverse slide 32. Due to the limited installation space on the bracket 31, the first sliding drive mechanism 33 is a magnetic rodless cylinder. The magnetic rodless cylinder requires less space during installation, and the transverse slide 32 is connected to the magnet on the magnetic rodless cylinder. The magnetic rodless cylinder drives the piston movement through electromagnetic force, which can achieve rapid start and stop and action response.

[0045] In fact, the stand 2 is also provided with a barcode scanner 103, a first marker 101 and a second marker 102. Each lower box 42 is provided with a unique identification code. The barcode scanner can enter the information into the management system by scanning the identification code, so as to track and record the assembly process and related data of each lower box 42, which is of great significance for quality control, product traceability and subsequent optimization and improvement; when the lower box 42 is successfully installed with the faucet 44, the first marker marks the specific position on the side of the lower box 42 (such as using the ink of a neutral pen to form a clear mark), and when the lower box 42 is successfully installed with the explosion-proof valve 43, the second marker marks the specific position on the side of the lower box 42 (such as using the ink of a neutral pen to form a clear mark).

[0046] In order to provide external protection for the faucet and explosion-proof valve 4 assembly machine and ensure the safety of surrounding personnel when the faucet and explosion-proof valve assembly machine is in operation, the faucet and explosion-proof valve assembly machine is arranged in a cabinet 12, and a control button for controlling the faucet and explosion-proof valve assembly machine is provided on the cabinet 12.
