Abstract
Description
Technical Field
[0001] This invention relates to the field of injection molded part inspection technology, and in particular to an energy storage injection molded cover inspection system. Background Technology
[0002] The top cover of the energy storage battery pack is mostly made of large injection molded parts, characterized by large size, thin walls, and easy warping and deformation. It also has high precision requirements for the positional accuracy of the mounting holes, the flatness of the flange surface, and the overall contour. To ensure the assembly quality and sealing performance of the energy storage battery pack, each injection molded top cover must undergo strict testing of its hole positions and flatness before leaving the factory.
[0003] Currently, the inspection of energy storage injection molded covers mainly relies on manual inspection using measuring tools, which has the following problems:
[0004] First, the positioning reference is unreliable. Large injection molded parts lack a unified positioning reference during inspection, making it easy for the workpiece to shift after placement, resulting in significant errors in the inspection results and making it difficult to ensure consistency in the inspection.
[0005] Second, there is a lack of contour-following supports adapted to the complex shapes of injection molded parts. Energy storage injection molded top covers have complex structures such as reinforcing ribs and undercuts. Existing testing fixtures are mostly planar or point supports, which cannot conform to the bottom contour of the workpiece. During testing, improper support can easily cause secondary deformation, affecting the testing accuracy.
[0006] Third, the hole position detection efficiency is low. There are multiple mounting holes distributed on the flange surface of the energy storage injection molded cover. The traditional method involves inserting detection pins one by one for detection, which is cumbersome, time-consuming and labor-intensive, and cannot meet the needs of batch online detection.
[0007] Fourth, flatness and warpage testing is inconvenient. Flatness testing of large injection molded parts usually requires readings at multiple measurement points, which is a complex process with low testing efficiency.
[0008] To address the above problems, some improvements have been made in the existing technology, such as:
[0009] Chinese patent CN211783278U discloses a workpiece bending deformation measuring tool. After establishing a reference plane through a reference hole, the distance between the top surface of the protrusion and the reference plane is measured to determine the severity of the bending deformation of the injection molded part.
[0010] Chinese patent CN207007131U discloses a device for detecting the hole position of injection molded parts, which uses a cylinder to drive the positioning of injection molded parts and the detection of through holes.
[0011] However, these technical solutions either only target a single inspection item (only detecting deformation or only detecting hole position) or use power components such as cylinders for driving. For large injection molded parts, the equipment is costly, complex in structure, and difficult to meet the comprehensive inspection needs of multiple inspection indicators. Summary of the Invention

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0029] This invention forms an annular platform-like structure that matches the shape and size of the workpiece to be tested through a support assembly. The inner platform surface supports the flange of the workpiece, while the outer platform surface is higher than the inner platform surface and avoids edge structures. This allows the workpiece to be positioned using only the flange as the primary positioning reference, achieving rapid and accurate positioning in conjunction with the primary positioning pin. This avoids positioning deviations caused by interference from edge structures or improper support, fundamentally ensuring the consistency of the testing reference.
[0030] This invention features a contoured support assembly within the inner space of the support platform. A fixed support plate is fixedly connected to the worktable via contoured support columns, while a movable support plate can be slidably adjusted along the width of the worktable via a position adjustment unit. For large injection-molded parts experiencing thermal expansion and contraction due to seasonal temperature changes, the position of the movable support plate can be adjusted to ensure it always conforms to the inner wall of the workpiece being tested. This avoids insufficient support or over-positioning due to changes in workpiece dimensions, effectively preventing secondary deformation of the workpiece during testing.
[0031] The hole position detection component of this invention employs a manual control assembly in conjunction with a linkage mechanism, enabling a single handle to simultaneously control the extension or retraction of multiple elastic pin units, allowing for the simultaneous detection of multiple holes on the flange surface in a single operation. Compared to the traditional method of detecting pins one by one, this significantly improves hole position detection efficiency; compared to a fully automatic cylinder-driven solution, it significantly reduces equipment costs and maintenance difficulty, balancing efficiency and cost.
[0032] The sliding detection component of this invention can slide along the length of the worktable to any predetermined detection position. The probe of the first dial indicator contacts the top surface of the workpiece to be tested, and can quickly read the flatness or warpage data of each measurement point. At the same time, the detection head of the bottom detection component contacts the bottom surface of the workpiece to be tested, and measures the workpiece profile from the bottom. The two components work together to achieve comprehensive detection of the top flatness, warpage, and bottom profile of the energy storage injection molded cover.
[0033] The invention features a rational overall structural layout. The support platform assembly is formed by splicing together several support blocks, facilitating processing and assembly. The top of the worktable has a flat mounting surface, and the layout of each functional component is clear. Ample space is provided for workpiece placement and removal, making manual placement of parts time-saving and labor-saving, and it is particularly suitable for batch online inspection of large injection molded parts.
[0034] In summary, this invention achieves rapid, accurate, and comprehensive online inspection of energy storage injection molded top covers through the coordinated operation of the support assembly, clamping assembly, contour support assembly, sliding detection assembly, bottom detection assembly, and hole position detection assembly. It effectively reduces equipment costs and improves inspection efficiency while ensuring inspection accuracy. Attached Figure Description

Detailed Implementation
[0051] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0052] like Figures 1 to 14 As shown, this invention provides an energy storage injection molding cover inspection system, which includes a worktable 1, a sliding inspection component 2, a clamping component 3, a support platform component 5, a contour support component 6, a bottom inspection component 7, a hole position inspection component 9, and a manual control component 10. The worktable 1 serves as the basic support platform for this inspection system, used to install and support the aforementioned functional components. Preferably, the worktable 1 is made of rigid metal material, and its top has a flat mounting surface.
[0053] like Figure 1 and Figure 7 As shown, the support assembly 5 is set on the top of the workbench 1, and the support assembly 5 is formed by splicing together several support blocks 500. Specifically, multiple support blocks 500 are fixedly connected to the top of the workbench 1 by bolts to form a ring structure, which is used to support the workpiece 4 to be tested, which corresponds to its shape and size. In this scheme, the workpiece to be tested is the energy storage injection molded top cover.
[0054] More specifically, several support blocks 500 collectively form an annular truncated structure that matches the shape and size of the workpiece 4 to be tested. The top surface of this annular truncated structure includes an inner platform 502 located in the inner ring and an outer platform 501 located in the outer ring. The outer platform 501 is higher than the inner platform 502. The outer platform 501 is used to avoid the edge structure of the workpiece 4 to be tested and does not bear the pressure of the workpiece 4. The inner platform 502 is used to support the flange of the workpiece 4 to be tested, thus providing primary support for the workpiece 4. (See reference...) Figure 14 The top surface of the support assembly 5 is also provided with a main positioning pin 507. The main positioning pin 507 is used to cooperate with the positioning hole on the shell of the workpiece 4 to be tested when it is placed, so as to realize the rapid positioning of the workpiece 4 on the support assembly 5. Further, a fixing seat 503 is provided at the bottom of the support block 500. The fixing seat 503 is used to fix the support block 500 on the worktable 1. The support block 500 is also provided with a detection slot 505 and a through hole 506. The detection slot 505 is used to avoid the reinforcing ribs or undercut structure of the workpiece 4 to be tested. The through hole 506 is provided to facilitate the subsequent installation and maintenance of the hole detection assembly 9, and the through hole 506 is also more in line with the requirements of product lightweight design.
[0055] like Figure 2 and Figure 3As shown, in this scheme, there are several clamping components 3, which are evenly distributed around the support assembly 5. They are used to clamp the edge of the workpiece 4 to be tested after it has been placed and positioned on the support assembly 5 by the main positioning pin 507, so as to facilitate subsequent testing.
[0056] In this embodiment, the clamping assembly 3 includes a clamping frame 301, a clamping arm 302, a movable arm 303, and a clamping head 304. The clamping frame 301 is fixed to the top surface of the workbench 1. Preferably, the bottom end of the clamping frame 301 is bolted to the workbench 1. The bottom of the clamping arm 302 is rotatably connected to the top of the clamping frame 301. Specifically, the bottom of the clamping arm 302 is pivotally connected to the top of the clamping frame 301 via a first pivot. One end of the movable arm 303 is rotatably connected to the clamping frame 301. Specifically, one end of the movable arm 303 is pivotally connected to the clamping frame 301 via a second pivot. The middle portion of the clamping arm 302 is movably connected to the middle portion of the movable arm 303. Preferably, a groove is formed in the middle portion of the clamping arm 302, and a sliding pin is provided in the middle portion of the movable arm 303. The sliding pin slidably engages within the groove, thereby achieving the movable connection between the clamping arm 302 and the movable arm 303. The end of the movable arm 303 is also fixed with a pressure head 304 for pressing the workpiece 4 to be tested. When the pressure arm 302 is raised, the movable arm 303 is driven to press the pressure head 304 downwards and press it against the workpiece 4 to be tested. Specifically, when the operator pulls the pressure arm 302 upwards, the pressure arm 302 drives the movable arm 303 to rotate around the second pivot through the above-mentioned movable connection, causing the pressure head 304 at the end of the movable arm 303 to move downwards and press the workpiece 4 to be tested.
[0057] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the sliding detection component 2 includes a movable stage 201 slidably connected to the worktable 1. The movable stage 201 is provided with several sets of detection modules, and the movable stage 201 can slide above the workpiece 4 to be tested along the length direction of the worktable 1, so as to perform detection using the detection modules at any position.
[0058] Reference Figure 6 Specifically, slide rails 213 are provided on both sides of the top of the workbench 1 along its length, and base plates 212 are fixed on both sides of the bottom of the movable table 201. A slider is provided at the bottom of the base plate 212 to slide in cooperation with the slide rails 213. The movable table 201 is slidably mounted on the workbench 1 through the cooperation of the slider and the slide rails 213. (Refer to...) Figure 5 The movable table 201 is also equipped with a positioning block 215 and a positioning bolt 214. When the movable table 201 slides along the length of the worktable 1 to the predetermined detection position, the positioning bolt 214 and the positioning block 215 are engaged and locked to achieve the positioning and locking of the movable table 201 on the worktable 1.
[0059] Please refer to Figure 3 and Figure 4 Furthermore, the detection module includes a sliding detection unit and a fixed detection unit. The fixed detection unit is fixedly mounted on the movable platform 201, and the sliding detection unit is capable of sliding along the length of the movable platform 201. Both the sliding detection unit and the fixed detection unit include a mounting plate 207 and a positioning plate 202. For the fixed detection unit, the positioning plate 202 is fixedly connected to the movable platform 201; for the sliding detection unit, the positioning plate 202 is mounted on the movable platform 201 via a sliding fit structure. Specifically, a slide rail 205 is provided on the movable platform 201 along its length, and the bottom of the positioning plate 202 of the sliding detection unit is provided with a slider that slides in cooperation with the slide rail 205. The positioning plate 202 is slidably mounted on the movable platform 201 through the cooperation of the slider and the slide rail 205. The movable table 201 is also equipped with a positioning hole 204 and a positioning bolt 203. When the sliding detection unit slides along the length of the movable table 201 to a predetermined position, the positioning bolt 203 passes through the positioning hole 204 and abuts against the positioning plate 202, thereby locking the sliding detection unit on the movable table 201. The mounting plate 207 is detachably connected to the end of the positioning plate 202. The mounting plate 207 is equipped with a mounting hole 210, on which a first dial indicator 206 is mounted. Specifically, the detection head of the first dial indicator 206 passes vertically downward through the mounting hole 210 and extends towards the top surface of the workpiece 4 to be measured, for detecting the gap between the bottom of the first dial indicator 206 and the top of the workpiece 4. The movable table 201 is also equipped with a go / no-go gauge 208 for easy access. The go / no-go gauge 208 is used to assist in detecting the hole dimensions at different positions on the workpiece 4.
[0060] like Figure 7 , Figure 8 As shown, the bottom detection assembly 7 includes several horizontal plates 701 and support columns 702 for connecting the worktable 1 and the horizontal plates 701. Specifically, the bottom end of the support column 702 is fixedly connected to the top of the worktable 1, and the top end of the support column 702 is fixedly connected to the bottom of the horizontal plate 701. The horizontal plate 701 is suspended above the worktable 1 by the support columns 702. Several measuring holes 703 are distributed on the horizontal plate 701, and a detection head 802 is installed at each measuring hole 703. The detection head 802 is electrically connected to a second dial indicator 801 fixed on the worktable 1 and is used to detect the gap between the detection head 802 and the bottom surface of the workpiece 4 to be measured.
[0061] Preferably, in this embodiment, the detection head 802 is a contact displacement sensor, with its tip passing through the measuring hole 703 and pointing towards the bottom surface of the workpiece 4 to be measured. When the workpiece 4 is placed on the support assembly 5, the tip of the detection head 802 contacts the bottom surface of the workpiece 4, and the detection head 802 transmits the displacement signal to the second dial indicator 801 for display, facilitating rapid reading and recording of the detection data. (Refer to...) Figure 6 and Figure 7 Symmetrical measuring holes 703 are arranged on the horizontal plates 701 on both sides. In this embodiment, four measuring holes 703 are evenly arranged on each side, for a total of eight measuring holes 703, all of which are used to measure the workpiece 4 to be measured from the bottom. The bottom surface of the horizontal plate 701 of the bottom detection assembly 7 is provided with a mounting block for fixing the detection head 802. The detection head 802 is connected to the mounting block by a threaded connection or a snap-fit method, and the mounting block can be detachably fixed to the horizontal plate 701 by bolts.
[0062] like Figure 7 , Figure 9 , Figure 10 and Figure 11 As shown, the contour support assembly 6 is arranged around the inner space of the support assembly 5, and includes a movable support plate 601, a contour support column 602, and a fixed support plate 603. Specifically, several movable support plates 601 are arranged on both sides along the length of the worktable 1, and several fixed support plates 603 are arranged along the width of the worktable 1. The fixed support plates 603 are fixedly connected to the worktable 1 through the contour support columns 602. Specifically, the bottom end of the contour support column 602 is fixedly connected to the top of the worktable 1, and the top end of the contour support column 602 is fixedly connected to the bottom of the fixed support plate 603.
[0063] The movable support plate 601 and the fixed support plate 603 are used to contact the inner wall of the workpiece to be tested from the inside.
[0064] A position adjustment unit is connected to the bottom of the movable support plate 601 to achieve a sliding connection between the movable support plate 601 and the worktable 1. The position adjustment unit includes an adjustment base plate 608, a contour support slider 607 installed at the bottom of the adjustment base plate 608, and a contour support guide rail 606 that cooperates with the contour support slider 607. Specifically, the contour support guide rail 606 is fixedly installed on the top of the worktable 1 along the width direction of the worktable 1, the adjustment base plate 608 is slidably installed on the contour support guide rail 606 via the contour support slider 607, and the movable support plate 601 is fixedly installed on the top of the adjustment base plate 608. Three adjustment knobs 605 are provided on the adjustment base plate 608 along the extension direction of the contour support guide rail 606. The distance the adjustment base plate 608 slides is controlled by adjusting the three adjustment knobs 605, and the three adjustment knobs 605 represent three different distance settings. Preferably, the adjusting knob 605 is a threaded knob, with its threaded end passing through the adjusting base plate 608 and selectively abutting against different limit positions, thereby realizing the adjustment of three different distance levels.
[0065] In this embodiment, since the workpiece 4 to be tested is a large injection molded part, it will undergo thermal expansion and contraction under different seasonal temperature changes, resulting in changes in its contour dimensions. By adjusting the position of the contour support column 602, the support position of the movable support plate 601 can always be in close contact with the inner wall of the workpiece 4 to be tested, avoiding insufficient support or over-positioning due to changes in workpiece size, thereby ensuring detection accuracy. The contour support assembly 6 also includes a handle 604, which is located on the top of the adjustment base plate 608, making it convenient for the operator to hold and push and pull the movable support plate 601 to adjust its position.
[0066] like Figure 2 , Figure 12 As shown, the hole position detection component 9 includes an elastic pin unit, a detection hole that vertically penetrates the support block 500, and a through hole 506 that horizontally penetrates the support block 500 and communicates with the detection hole. The detection hole starts from the inner platform surface 502 of the support component and extends vertically downward, and the through hole 506 communicates with the middle of the detection hole.
[0067] Reference Figure 12The elastic pin unit includes an elastic pin head 901, a central sleeve 902, a pull hole 903, a pull head 904, a connector 905, a limiting block 906, a connecting head 907, a movable sleeve 908, and a top plate 909. The central sleeve 902 is fixed in the detection hole; specifically, the outer wall of the central sleeve 902 is fixedly fitted with the inner wall of the detection hole. The movable sleeve 908 slides through the central sleeve 902; specifically, the outer wall of the movable sleeve 908 slidesly fitted with the inner wall of the central sleeve 902. The elastic pin head 901 is connected to the top of the movable sleeve 908. The top plate 909 is slidably disposed on the outer side of the elastic pin head 901 and is fixedly connected to the detection hole. Specifically, the top plate 909 is fixedly installed at the top opening of the detection hole (i.e., at the inner platform 502), and the elastic pin head 901 slides through the top plate 909 and extends upwards out of the inner platform 502. The bottom of the movable sleeve 908 has a pull hole 903, and a pull head 904 is movably disposed within the pull hole 903. Preferably, the pull head 904 is engaged within the pull hole 903. A connector 905 is connected to the bottom of the pull head 904, and the connector 905 movably passes through the movable sleeve 908. Specifically, the top end of the connector 905 passes through the bottom of the movable sleeve 908 and is fixedly connected to the pull head 904. A limit block 906 is fixed to the outer side of the bottom of the connector 905. The top surface of the limit block 906 contacts and engages with the bottom surface of the support block 500 to limit the overall upward movement of the elastic pin unit, preventing the elastic pin head 901 from protruding too high and damaging the workpiece 4 under test or the detection structure.
[0068] The bottom end of the connector 905 is also provided with a connector head 907. In this scheme, multiple elastic pin units are provided, which are distributed around the support assembly 5 and correspond one-to-one with the holes on the workpiece 4 to be tested. The manual control assembly 10 is used to control the synchronous extension or retraction of multiple elastic pin heads 901. Specifically, the manual control assembly 10 includes a handle and a linkage mechanism. The handle is located at the edge of the worktable 1, and the linkage mechanism is located inside the worktable 1. One end of the linkage mechanism is connected to the handle, and the other end of the linkage mechanism is connected to the connector head 907 of each elastic pin unit. By moving the handle, the linkage mechanism is driven to move, and the linkage mechanism simultaneously drives each connector head 907 to move, thereby causing each movable sleeve 908 to slide relative to the central sleeve 902, so that each elastic pin head 901 synchronously retracts downward or extends upward. When the elastic pin head 901 can smoothly extend out of the hole corresponding to the position of the workpiece 4 to be tested, it means that the test is qualified. The workbench 1 is also equipped with a mounting base for installing the manual control component 10. The manual control component 10 is fixed to the edge of the workbench 1 via the mounting base, facilitating operation by the operator. The connecting member 905 can be made of steel wire rope, which facilitates the transmission of tension, and is used in this design.
[0069] The working process of this detection system is explained below with reference to the accompanying drawings:
[0070] First, the workpiece 4 to be tested is placed on the support assembly 5. The main positioning pin 507 engages with the positioning hole at the bottom of the workpiece 4 to achieve rapid positioning, ensuring that the flange of the workpiece 4 contacts the inner platform 502, while the edge structure of the workpiece 4 is avoided by the outer platform 501. Then, the clamping assembly 3 is operated, and the pressure arm 302 is pulled upwards, causing the pressure head 304 to press downwards against the edge of the workpiece 4, completing the positioning and clamping of the workpiece.
[0071] It should be noted that before the workpiece to be tested is loaded, the staff adjusts the position of the movable support plate 601 by adjusting the knob 605 according to the actual size of the workpiece 4 to be tested and the seasonal temperature changes, so that the contour support column 602 provides appropriate support to the bottom of the workpiece 4 to be tested, so that the movable support plate 601 can effectively support the workpiece to be tested.
[0072] After loading, the movable table 201 can be pushed along the length of the worktable 1 (via slide rail 213) to the predetermined detection position, and the movable table 201 is locked by positioning bolt 214 and positioning block 215. Then, the positioning plate 202 of the sliding detection unit is pushed along the length of the movable table 201 (via slide rail 205) to the predetermined position, and the sliding detection unit is locked by positioning bolt 203 passing through positioning hole 204. At this time, the probe of the first dial indicator 206 contacts the top surface of the workpiece 4 to be measured, and the flatness or warpage data at that position can be obtained by reading the value of the first dial indicator 206.
[0073] At the same time, the detection head 802 of the bottom detection component 7 contacts the bottom surface of the workpiece 4 to be tested, and the second dial indicator 801 displays the corresponding gap value, which is used to measure the contour of the workpiece 4 to be tested from the bottom and complete the rapid detection with no blind spots.
[0074] Simultaneously, the staff also need to inspect the holes at the edge of the workpiece to be tested. Specifically, by operating the handle of the manual control component 10, the connecting heads 907 are simultaneously driven to move through the linkage mechanism, causing the elastic pins 901 to extend upwards synchronously. If each elastic pin 901 can smoothly pass through the corresponding hole in the workpiece 4 to be tested, it indicates that the position and size of each hole are qualified; if a certain elastic pin 901 cannot extend or is stuck, it indicates that the hole at the corresponding position is unqualified.
[0075] After the test is completed, the manual control component 10 is operated in reverse. Through the linkage mechanism, each connector 907 is driven to move in the opposite direction, which causes each elastic pin 901 to retract downward synchronously, releasing the clamping component 3, removing the workpiece 4 to be tested, and then the next workpiece can be tested.
[0076] In summary, the energy storage injection molding cover detection system provided by this invention achieves rapid, accurate, and comprehensive online detection of energy storage injection molding covers through the coordinated operation of the support assembly, clamping assembly, contour support assembly, sliding detection assembly, bottom detection assembly, and hole position detection assembly. This effectively solves the problems mentioned in the background art, such as unreliable positioning reference, easy secondary deformation, and low hole position detection efficiency.
