[0021] Step 2: Position and group each component, convey them step by step in groups, combine them step by step in groups, and continuously riveting, testing and unloading;

[0022] Step 3: The laser rangefinder obtains the thickness value, substitutes it into the regression equation, and calculates the compression amount, so as to identify and mark the defective products.

[0023] Beneficial effects of the present invention:

[0024] (1) In each step, the rubber ring dispenser simultaneously puts the C-shaped sealing ring on the riveted pole, each feeding robot arm places each corresponding part on the pressure-bearing mold frame in its own station, the riveter rivets each component set on the pressure-bearing mold frame in its own station into a battery cover plate, the laser rangefinder measures the thickness of the riveted pole in the battery cover plate on the pressure-bearing mold frame in its own station, the laser rangefinder substitutes the thickness into the equation to derive the measured pressure thickness of the internal C-shaped sealing ring and marks the defective products, and the feeding robot arm at the last station sequentially removes the obtained products from the pressure-bearing mold frame and places them on the feeding conveyor belt, so that each station in each step runs a process at the same time, thereby compressing the production interval time of each product as a whole, achieving the best work efficiency and work quality, and at the same time, the annular guide rail composed of the superior arc guide rail and the inferior arc guide rail is used to form the simplest circulation structure of the pressure-bearing mold frame, thereby reducing equipment costs and saving floor space;

[0025] (2) During operation, the force-applying ring plate moves up and down, thereby adjusting the extension distance of each fork frame together with the positioning circular plate, thereby simultaneously expanding or contracting each clamping claw rod. Before clamping the moving component, each clamping claw rod is first contracted, and then the clamping claw rod is moved to the center of the component slot, and then the clamping claw rod is expanded, so that the annular clamping claw can face the annular, circular or circular slotted component to keep the position of the acquired component directly below the clamping claw, thereby accurately positioning the component, and through the annular expansion and contraction, it is avoided that the force in one direction is too large to damage the component during acquisition;

[0026] (3) During operation, the position of each group of feeding mechanical claws is adjusted by the feeding push rod, so that in each step, one group of feeding mechanical claws moves to the top of the corresponding pressure-bearing mold frame and the other group of feeding mechanical claws moves to the top of the corresponding component group. The second slide bar and the first slide bar enable each linkage ring and the clamping claw rod to move simultaneously, so as to accurately maintain the posture of each component after acquisition and accurately stack them during assembly and stacking. In addition, an annular expansion and vertical fixed-point stacking method are adopted for the soft sealing ring and other components matched therewith, so as to avoid missing and avoid the air interlayer caused by the adhesion of the components to the sealing ring when stacking, thereby ensuring the stacking accuracy;

[0027] (4) When working, the sharp part of the lower end of the clamping claw rod is distributed in a circular shape around the edge of the center protrusion of the landing point. As the support slider moves downward, it first contacts the protrusion and shrinks into the installation groove, so that the sharp part of the clamping claw rod just wraps around the side wall of the protrusion, so that after unloading, the obtained parts are accurately placed around the middle of the center protrusion of the landing point, so that the parts when stacked are not only accurately positioned in the horizontal and vertical dimensions, but also accurately positioned in the vertical direction, thereby achieving accurate positioning in three dimensions;

[0028] (5) During operation, the relationship between pole height and sealing ring compression is obtained through the regression equation obtained through previous data collection and regression analysis, so that the compression can be obtained without destroying the product. At the same time, the screening step can be completed in as short as one step to complete the test and valuation, maintaining high efficiency and achieving low cost.

[0051] The lower end of the clamping claw rod 504 protrudes downwards near the unloading slide bar 505 to form a sharp structure. The other side of the clamping claw rod 504 is provided with a mounting groove 520. A limit slider 521 is slidably connected in the mounting groove 520. A support spring 522 is installed between the limit slider 521 and the groove top of the mounting groove 520. A support slider 523 is installed at the lower end of the limit slider 521.

[0052] When the rubber ring dispenser 105 is working, the C-shaped sealing rings 902 are evenly stacked in a vertical row through the feeding barrel 205, and the C-shaped sealing rings 902 are successively placed on the rubber ring conveyor belt 202 and transported to the delivery mechanical claw 204.

At the same time, the rubber ring dispenser 105 can also be set at other stations where circular plate-shaped components need to be placed on the feeding conveyor belt 106, so that the circular plate-shaped components The parts can be accurately grouped and evenly placed according to the set positions. When the feeding mechanical arm 107 is working, the feeding mechanical claws 305 are divided into two groups according to the assembly process. The position of each group of feeding mechanical claws 305 is adjusted by the feeding push rod 303, so that in each step, one group of feeding mechanical claws 305 moves to the top of the corresponding pressure-bearing mold frame 103 and the other group of feeding mechanical claws 305 moves to the top of the corresponding component group. The distribution of the annular clamping claws 406 is further adjusted by the feeding slide 304 and the width adjustment slide 402, so that the annular The clamping jaw 406 is located directly above the clamped component. When the annular clamping jaw 406 is working, the first push rod 401 adjusts the vertical distance between itself and the clamped component. When clamping, the force ring plate 502 moves up and down, thereby adjusting the extension distance of each fork frame 503 together with the positioning circular plate 501, thereby simultaneously expanding or contracting each clamping jaw rod 504. Before clamping the moving component, each clamping jaw rod 504 is first contracted, and then the clamping jaw rod 504 is moved to the center of the component slot, and then the clamping jaw rod 504 is expanded, so as to accurately obtain the component. Then, when the component is just above the set drop point, the linkage ring 508 moves down, and the unloading slide bar 505 is pushed down by transmission to accurately drop the component at the drop point.

[0053] When there is a protrusion in the center of the landing point during stacking and the acquired parts need to be placed in the middle of the landing point part, the sharp part of the lower end of the clamping claw rod 504 is distributed in a circular shape around the edge of the protrusion in the center of the landing point. As the supporting slider 523 moves downward, it first contacts the protrusion and shrinks into the installation groove 520, so that the sharp part of the clamping claw rod 504 just wraps around the side wall of the protrusion, so that the acquired parts can be accurately placed around the middle of the protrusion in the center of the landing point after unloading.

A second spring rod 703 is symmetrically installed on one side of the second baffle plate 702 away from the feeding robot arm 107, and a second pressing plate 704 is installed on the lower end of the second spring rod 703.

[0056] When this embodiment is working, the distribution of circular components in each group is adjusted by the first width adjuster 108, and the distribution of square components in each group is adjusted by the second width adjuster 109. When adjusting the circular components, the first telescopic rod 601 periodically moves the first baffle plate 602 up and down to adjust the spacing between circular components in different rows. The spacing between two columns of circular components is adjusted by adjusting the spacing between two width adjusting baffle plates 603. The first spring rod 604 and the first pressure plate 605 are used to prevent the circular components from sticking to the first baffle plate 602. When adjusting the square components, the second baffle plate 702 is periodically moved up and down by the second telescopic rod 701 to adjust the spacing between each square component and group them. The second spring rod 703 and the second pressure plate 704 are used to prevent the square components from sticking to the second baffle plate 702.

[0057] The working method of the battery cover assembly detection device comprises the following steps:

[0058] Step 1: collect the heights of several groups of riveted poles 901 after being compressed and the compression amounts of the C-shaped sealing rings 902, and analyze the values ​​by regression equation, and determine the regression equation that meets the condition of P value < 0.05 according to whether the regression equation meets the condition;

[0059] Step 2: At each workstation, the feeding conveyor belt 106 positions and groups the riveted pole 901, the stop frame 903, the positioning cover plate 904, the weak guide plate 905 and the riveted pressure plate 906 and conveys them in groups. In each step, the rubber ring dispenser 105 puts the C-shaped sealing ring 902 on the riveted pole 901, each feeding mechanical arm 107 places each corresponding part on the pressure-bearing mold frame 103 in its own workstation, and the riveting press 110 rivets each component set on the pressure-bearing mold frame 103 in its own workstation. The laser rangefinder 111 measures the thickness of the riveted pole 901 in the battery cover plate on the pressure-bearing mold frame 103 in its own station, and the laser rangefinder 111 substitutes the thickness into the equation to deduce the pressure-bearing thickness of the measured internal C-shaped sealing ring 902 and marks the unqualified products. The feeding robot arm 107 at the last station takes the obtained products from the pressure-bearing mold frame 103 in turn and puts them on the feeding conveyor belt 106, so that the stations correspond to the processes, and each station runs a process at the same time for each step, thereby compressing the production interval time of each product as a whole;

[0060] Step 3: After the laser rangefinder 111 obtains the thickness values ​​of each compressed riveted pole 901, it is substituted into the regression equation obtained in step 1 to calculate the corresponding compression amount of the C-shaped sealing ring 902, so as to identify and mark the defective products that are not within the range.

[0061] When the present invention is in use, the staff flexibly sets the number of workstations and the number of pressure-bearing mold frames 103 according to the number of parts of the product, and always makes the last three workstations respectively the riveter 110, the laser rangefinder 111, and the feeding robot arm 107 and the feeding conveyor belt 106 for unloading the final finished product cover plate, and in each step, the rubber ring dispenser 105 simultaneously sleeves the C-shaped sealing ring 902 on the riveted pole 901, each feeding robot arm 107 places each corresponding part on the pressure-bearing mold frame 103 in its own workstation, the riveter 110 rivets each component set on the pressure-bearing mold frame 103 in its own workstation into a battery cover plate, and the laser rangefinder 111 places the pressure-bearing mold frame 103 in its own workstation. The thickness of the compressed riveted pole 901 in the battery cover on the frame 103 is measured, the laser rangefinder 111 substitutes the thickness into the equation to deduce the compressed thickness of the measured internal C-shaped sealing ring 902 and marks the unqualified products, and the feeding robot arm 107 on the last station takes the obtained products from the pressure-bearing mold frame 103 in turn and puts them on the feeding conveyor 106, so that each step and each station runs a process at the same time, thereby compressing the production interval time of each product as a whole, achieving the best work efficiency and work quality, and at the same time, the annular guide rail composed of the superior arc guide rail 101 and the inferior arc guide rail 102 is used to form the simplest circulation structure of the pressure-bearing mold frame 103, reducing equipment costs and saving floor space;

[0062] During operation, the force ring plate 502 moves up and down, thereby adjusting the extension distance of each fork frame 503 together with the positioning circular plate 501, thereby simultaneously expanding or contracting each clamping claw rod 504. Before clamping the moving component, first contract each clamping claw rod 504, then move the clamping claw rod 504 to the center of the component slot, and then expand the clamping claw rod 504, so that the annular clamping claw 406 can face the annular, circular or circular slotted component to keep the position of the acquired component directly below the clamping claw, thereby accurately positioning the component, and through the annular expansion and contraction, it is avoided that the force in one direction is too large to damage the component during acquisition;

[0063] During operation, the position of each group of feeding mechanical claws 305 is adjusted by the feeding push rod 303, so that in each step, one group of feeding mechanical claws 305 moves to the top of the corresponding pressure-bearing mold frame 103 and the other group of feeding mechanical claws 305 moves to the top of the corresponding component group, and the second slide bar 518 and the first slide bar 515 enable each linkage ring 508 and the clamping claw rod 504 to move simultaneously, so as to accurately maintain the posture of each component after acquisition and accurately stack them during assembly and stacking, and annular expansion and vertical fixed-point stacking methods are adopted for the soft sealing ring and other components matched therewith, so as to avoid leakage, and avoid the adhesion of components to the sealing ring when stacking to form an air layer, thereby ensuring the stacking accuracy;

[0064] When working, the sharp part of the lower end of the clamping claw rod 504 is distributed around the edge of the center protrusion of the landing point in a circular shape. As the support slider 523 moves downward, it first contacts the protrusion and shrinks into the installation groove 520, so that the sharp part of the clamping claw rod 504 just wraps around the side wall of the protrusion, so that after unloading, the obtained parts are accurately placed around the middle of the center protrusion of the landing point, so that the parts when stacked are not only accurately positioned in the horizontal two dimensions, but also further accurately positioned in the vertical direction, so as to achieve accurate positioning in three dimensions;

[0065] During operation, the relationship between pole height and sealing ring compression is obtained through the regression equation obtained through previous data collection and regression analysis, so that the compression amount can be obtained without destroying the product. At the same time, the screening step can be completed in as short as one step to complete the test and valuation, maintaining high efficiency and achieving low cost.
