Description

Technical Field

[0001] This invention belongs to the field of connection unit manufacturing technology, specifically relating to a flexible testing and assembly system for a high-speed connection unit signal transmission core component. Background Technology

[0002] High-speed connection units are used to transmit high-speed data signals. Their core signal transmission components typically include a thin sheet, a flexible shield, and metal parts. Differences between different models of connection units may involve several aspects, such as the relative positions of internal components, color coding, or the structure of a specific component. Currently, there are two models of high-speed connection units that share the same flexible shield but differ in their thin sheet and metal parts. Separate production would result in high costs and a large system footprint. Therefore, how to achieve the production of both models of connection units through a single production system is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0003] The purpose of this invention is to provide a flexible detection and assembly system for the core components of high-speed connection unit signal transmission, so as to solve the above-mentioned problems existing in the prior art.

[0004] The technical solution adopted in this invention is as follows: a flexible detection and assembly system for the core component of high-speed connection unit signal transmission, comprising a sheet detection equipment group, a flexible shielding sheet cutting and assembly equipment, a metal part assembly equipment, and a metal part hot-melting equipment arranged sequentially from the system feed end to the system discharge end; the sheet detection equipment group includes sheet A detection equipment and sheet B detection equipment arranged side by side, with the discharge end of either sheet A detection equipment or sheet B detection equipment corresponding to the feed end of the flexible shielding sheet cutting and assembly equipment; the flexible shielding sheet cutting and assembly equipment includes a PIN binding module and a flexible shielding sheet group loading seat, the flexible shielding sheet group loading seat being used to position and support several products A and several products B, and being able to reciprocate along the system feed and discharge direction, the PIN binding module being used to bind the inverted U-shaped support of the flexible shielding sheet of product A and product B to the pins of the sheet of their respective products.

[0005] As a further optional solution, the PIN bundling module includes a pre-bundling PIN mechanism and a PIN bundling drive mechanism that drives the pre-bundling PIN mechanism to rise and fall. The pre-bundling PIN mechanism includes a left slider, a right slider, a slide block, a drive rod, a drive component that drives the drive rod to rise and fall, and several PIN bundling units. The left and right sliders are arranged side by side and slidably mounted on the slide block along the system's feed and discharge direction. Each PIN bundling unit includes a left clamping block fixed to the left slider and a right clamping block fixed to the right slider. The left clamping block has several left dials, and the right clamping block has several right dials. The left and right dials are staggered and are used to wrap the two ends of the inverted U-shaped support of the flexible shielding sheet to the outer surface of the pins of the sheet. Both the left and right sliders are provided with vertically penetrating grooves. The groove of the left slider corresponds to the system's feed and discharge directions. The left and right sides of the slide wall of the right slider are respectively provided with a first pin hole and a second pin hole that are tangentially connected to the slide groove. The slide groove of the right slider is provided with a third pin hole and a fourth pin hole that are tangentially connected to the slide groove on the left and right sides of the slide wall at both ends of the system's inlet and outlet. The first pin hole, the second pin hole, the third pin hole and the fourth pin hole are all horizontally set and axially perpendicular to the system's inlet and outlet directions, and each contains a pin. The first pin hole is higher than the second pin hole, and the third pin hole is lower than the fourth pin hole. The upper end of the drive rod extends into the slide grooves of both the left slider and the right slider. Both sides of the drive rod have an upper boss and a lower boss that can contact the pins. When the drive rod is raised and lowered to the first state, the upper boss contacts the pins in the first pin hole and the fourth pin hole. When the drive rod is raised and lowered to the second state, the lower boss contacts the pins in the second pin hole and the third pin hole.

[0006] As a further optional solution, the grooves of the left and right sliders are formed on their opposite sides, and the drive rod passes through both the left and right sliders simultaneously through their grooves. The first pin hole and the fourth pin hole are at the same height, and the second pin hole and the third pin hole are at the same height.

[0007] As a further optional solution, the PIN bundling module also includes a PIN bundling final pressing mechanism located at the discharge end of the pre-bundling PIN mechanism. The PIN bundling final pressing mechanism includes multiple upper riveting heads and multiple lower riveting heads corresponding to each other, as well as upper riveting head drive and lower riveting head drive that drive the upper riveting heads and lower riveting heads to rise and fall respectively. The upper riveting heads and lower riveting heads are respectively located above and below the inverted U-shaped support legs of each product on the flexible shielding sheet assembly mounting base. The lower riveting head has an adapter groove that matches the inverted U-shaped support legs of the bundled flexible shielding sheet.

[0008] As a further optional solution, the flexible shielding sheet cutting and assembly equipment includes a feeding track, a flexible shielding sheet cutting mechanism disposed on the feeding track, a cutting and conveying mechanism corresponding to the flexible shielding sheet cutting mechanism, a staggered spacing mechanism located at the discharge end of the feeding track, and an assembly and conveying mechanism; the cutting and conveying mechanism is used to press multiple flexible shielding sheets onto the flexible shielding sheet cutting mechanism and to convey the multiple cut flexible shielding sheets onto the staggered spacing mechanism; the staggered spacing mechanism is used to adjust the spacing of the multiple flexible shielding sheets to be consistent with the spacing of each product on the flexible shielding sheet assembly loading seat; the assembly and conveying mechanism is used to convey the multiple flexible shielding sheets on the staggered spacing mechanism onto the flexible shielding sheet assembly loading seat and press the flexible shielding sheets onto the thin sheet in the flexible shielding sheet assembly loading seat.

[0009] As a further optional solution, the metal component assembly equipment includes a metal component A feeding and cutting module, a metal component B feeding and cutting module, a metal component assembly loading seat, and an assembly and handling module for transporting metal components A and B from the metal component A feeding and cutting module and the metal component B feeding and cutting module to the metal component assembly loading seat, respectively. The metal component assembly loading seat is used to position and support several products A and several products B, and can reciprocate along the system's infeed and outfeed direction. A transfer and handling module is provided between the flexible shielding sheet cutting and assembly equipment and the metal component assembly equipment for transporting products A and B on the flexible shielding sheet assembly loading seat to the metal component assembly loading seat.

[0010] As a further optional solution, a sheet transfer module is provided between the discharge end of the sheet A testing device and the sheet B testing device and the infeed end of the flexible shielding sheet cutting and assembly device, for transferring the sheet A and sheet B after being tested by the sheet A testing device and the sheet B testing device respectively to the flexible shielding sheet assembly loading seat.

[0011] As a further optional solution, both the sheet A detection device and the sheet B detection device include at least one sheet detection adjustment module. When there are multiple sheet detection adjustment modules, they are arranged sequentially along the feeding and discharging direction of the system. The sheet detection adjustment module includes a detection mechanism and an adjustment mechanism. The detection mechanism is used to detect whether the angles of multiple pins on the sheet are consistent, and the adjustment mechanism is used to adjust pins at different angles to the same angle. The detection mechanism includes a controller and a CCD detector for taking pictures of the sheet. The adjustment mechanism includes an adjustment block for pressing the sheet above it and multiple top blocks corresponding to all pins on the sheet. Different top blocks are driven to rise and fall by different motors. The CCD detector acquires the angle value of each pin and sends it to the controller. The controller calculates the adjustment value based on the angle value of the pin acquired by the CCD detector and transmits the adjustment value to the motor. The motor then drives the top block to move according to the corresponding adjustment value.

[0012] As a further optional solution, a first detection angle of the sheet is detected by a CCD detector; an initial adjustment value is calculated based on the difference between the first detection angle and a preset target angle, and the springback angle corresponding to the sheet material; the pin angle is adjusted by a motor according to the initial adjustment value; the adjusted second detection angle is detected by a CCD detector; a second adjustment value is calculated based on the difference between the second detection angle and the target angle, and the springback angle; the adjustment and detection steps are repeated until the difference between the Nth detection angle and the target angle falls within a set range, where N is an integer greater than 1; the sum of the N adjustment values ​​is superimposed to obtain the correspondence between the first detection angle and the adjustment value; the correspondence is corrected using an artificial intelligence algorithm so that for any first detection angle, the difference between the adjusted detection angle and the target angle falls within a set range; the corrected correspondence is stored in a memory; during the production stage, the controller retrieves the corresponding adjustment value from the memory based on the detection angle detected in real time by the CCD detector and transmits it to the motor to adjust the pin angle; the artificial intelligence algorithm includes a neural network or deep learning model, which is trained using historical adjustment data to optimize the correspondence.

[0013] As a further optional solution, the sheet detection and adjustment module also includes multiple sheet detection carriers and a pushing mechanism that drives each sheet detection carrier to move toward the detection mechanism and the adjustment mechanism; the detection mechanism also includes a detection block for pressing the sheet above the sheet and an adjustment mechanism for driving the CCD detector to reciprocate toward the sheet detection carrier, and the detection block is height-adjustable.

[0014] The beneficial effects of this invention are as follows: by using sheet inspection equipment for two products arranged side by side, the sheets of the two products can be inspected simultaneously by their respective equipment. Then, the flexible shielding sheets of the two products are assembled together by the same flexible shielding sheet cutting and assembly equipment. Next, the metal parts of the two products are assembled separately by metal part assembly equipment. Finally, the metal parts are fixed to the sheets by sharing a metal part hot-melting equipment. This completes the co-line flexible production of two connection units with the same flexible shielding sheet but different sheets and metal parts, which greatly reduces costs and system space occupation, and achieves high-efficiency production of the two products on the basis of co-line production.

[0033] Furthermore, the technical features described herein, or the steps in all the methods or processes disclosed herein, may be combined in any suitable manner in one or more embodiments, except for mutually exclusive features and / or steps. It will be readily understood by those skilled in the art that the order of steps or operations of the methods relating to the embodiments provided herein may also be altered. Any order in the drawings and embodiments is for illustrative purposes only and does not imply a requirement to follow a particular order unless explicitly stated otherwise.

[0034] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, under reasonable circumstances (without self-contradiction), include both direct and indirect connections (linkages).

[0035] Figures 5 to 12This invention illustrates a flexible detection and assembly system for the core components of a high-speed connection unit signal transmission system, comprising a sheet detection equipment group, a flexible shielding sheet cutting and assembly equipment 100, a metal component assembly equipment, and a metal component hot-melting equipment 400 arranged sequentially from the system feed end to the system discharge end. The sheet detection equipment group includes sheet A detection equipment 200 and sheet B detection equipment 201 arranged side by side, with the discharge end of either sheet A detection equipment 200 or sheet B detection equipment 201 corresponding to the feed end of the flexible shielding sheet cutting and assembly equipment 100. The flexible shielding sheet cutting and assembly equipment 100 includes a PIN binding module and a flexible shielding sheet assembly loading seat 101. The flexible shielding sheet assembly loading seat 101 is used to position and carry several products A and several products B, and can reciprocate along the system feed and discharge direction, i.e., the direction between the system feed end and the discharge end. The PIN binding module is used to bind the inverted U-shaped support 21 of the flexible shielding sheet 2 of products A and B to the pins 11 of the sheet 1 of their respective products.

[0036] Figures 1 to 4 Two products are shown, differing in their sheet 1 and metal component 3, but identical in their flexible shielding sheet 2. This system assembles sheet 1, flexible shielding sheet 2, and metal component 3 sequentially, simultaneously completing the assembly of both products. The figure shows the state of the flexible shielding sheet 2 after its inverted U-shaped support 21 is wrapped around pin 11. Sheet A inspection device 200 and sheet B inspection device 201 simultaneously inspect the sheet 1 of both products, then proceed to the flexible shielding sheet cutting and assembly device 100. The sheet 1 of both products is placed on the flexible shielding sheet assembly loading seat 101, and the ends of the inverted U-shaped support 21 of the flexible shielding sheet 2 are bent towards the pin 11 of the sheet 1 using a PIN-binding module to wrap around the pin 11. Then, the metal component assembly device sequentially assembles the metal components 3 of both products.

[0037] Figures 6 to 9This diagram illustrates the structure of the flexible shielding sheet cutting and assembly equipment 100 in this embodiment. In this embodiment, the PIN bundling module may include a pre-bundling PIN mechanism 102 and a PIN bundling drive mechanism 103 that drives the pre-bundling PIN mechanism 102 to rise and fall. The pre-bundling PIN mechanism 102 includes a left slider 104, a right slider 105, a slide block 106, a drive rod 107, a drive component that drives the drive rod 107 to rise and fall, and several PIN bundling units. The left slider 104 and right slider 105 are arranged side-by-side and slidably mounted on the slide block 106 along the system's feed / discharge direction. Each PIN unit includes a left clamping block 108 fixed to the left slider 104 and a right clamping block 109 fixed to the right slider 105. The left clamping block 108 has several left dials 110, and the right clamping block 109 has several right dials 111. The left dials 110 and right dials 111 are staggered and are used to wrap the two ends of the inverted U-shaped support 21 of the flexible shielding sheet 2 around the outer surface of the pins 11 of the sheet 1. Both the left slider 104 and the right slider 105 are provided with vertically penetrating grooves 112. The groove 112 of the left slider 104 corresponds to the system's entry and exit. The left and right sides of the groove at both ends of the material feed are respectively provided with a first pin hole 113 and a second pin hole 114 that are tangentially connected to the slide groove 112. The slide groove 112 of the right slider 105 is respectively provided with a third pin hole 115 and a fourth pin hole 116 that are tangentially connected to the slide groove 112 at both ends of the system feed. The first pin hole 113, the second pin hole 114, the third pin hole 115 and the fourth pin hole 116 are all horizontally arranged and axially perpendicular to the feed direction of the system, and each contains a pin 117. The first pin hole 113 is higher than the second pin hole 114. 4. The third pin hole 115 is lower than the fourth pin hole 116; the upper end of the drive rod 107 extends into the groove 112 of the left slider 104 and the right slider 105 at the same time, and both sides of the drive rod 107 have an upper boss 118 and a lower boss 119 that can contact the pin 117. When the drive rod 107 is raised and lowered to the first state, the upper boss 118 contacts the pin 117 in the first pin hole 113 and the fourth pin hole 116. When the drive rod 107 is raised and lowered to the second state, the lower boss 119 contacts the pin 117 in the second pin hole 114 and the third pin hole 115.

[0038] The flexible shielding sheet assembly 101 carries the two product sheets 1 to the pre-bundling pin mechanism 102. After the flexible shielding sheet 2 is placed on the sheet 1, the inverted U-shaped support 21 is attached to the pins 11 of the sheet 1. The pin-bundling drive mechanism 103 drives the pre-bundling pin mechanism 102 to rise below the sheet 1 to avoid collision with the product. Each inverted U-shaped support 21 has a left dial 110 and a right dial 111 at both ends. Figure 9The diagram illustrates the internal operation, showing only the left slider 104. Therefore, the third pin hole 115 and the fourth pin hole 116 are virtual outlines. When the drive rod 107 is in the first state, the upper boss 118 contacts the pins 117 in the first and fourth pin holes 113 and 116, respectively. At this time, the left slider 104 and the right slider 105 are in their original positions. Under the drive of the drive unit, when the drive rod 107 is in the second state, the upper boss 118 moves away and no longer contacts the pins 117 in the first and fourth pin holes 113 and 116, while the lower boss 119... Contact with the pins 117 in the second pin hole 114 and the third pin hole 115, that is, by the lower boss 119 abutting against the pin 117 in the second pin hole 114, the left slider 104 is driven to slide to the right, and by the lower boss 119 abutting against the pin 117 in the third pin hole 115, the right slider 105 is driven to slide to the left, which in turn causes the left dial 110 of the left clamping block 108 to bend to the right at one end of the U-shaped support leg 21, and causes the right dial 111 of the right clamping block 109 to bend to the left at the other end of the U-shaped support leg 21, thus completing the pre-bundling of the flexible shielding sheet 2. When the upper and lower bosses 119 abut against the circumferential surface of the pins 117 on the left or right side of the slide groove 112, the corresponding slider can be driven to slide. The sliding distance can also be set by the size of the upper and lower bosses 119. The pin-binding action is cleverly achieved through the same drive rod 107. The structure is small and compact. Multiple actions are controlled by a single driver, which significantly reduces the number of drive components, simplifies the structure and reduces manufacturing costs. It also realizes micro-precision pin binding and can meet the precise operation requirements in small spaces. It solves the contradiction between driving force and stroke in traditional telescopic cylinders: the stroke is too long when the driving force is large, while the driving force is insufficient when the stroke is short, making it difficult to meet the needs of micro-operations. The structural design is reasonable and does not require additional hard limit devices, which further simplifies the system structure and improves the integration and reliability of the equipment.

[0039] The grooves 112 of the left slider 104 and the right slider 105 are formed on their opposite surfaces. The drive rod 107 passes through the grooves 112 of both sliders simultaneously. The first pin hole 113 and the fourth pin hole 116 are at the same height, and the second pin hole 114 and the third pin hole 115 are at the same height. In this way, the grooves 112 of the left and right sliders 105 are opposite to each other, and the drive rod 107 passes through the grooves 112 of both sliders simultaneously. The height of the pin holes is set in two ways, which simplifies the structure and realizes synchronous action, saves action time and improves efficiency.

[0040] In some specific embodiments, the flexible shielding sheet cutting and assembly equipment 100 may include a feeding track 120, a flexible shielding sheet cutting mechanism 121 disposed on the feeding track 120, a cutting and transporting mechanism 122 corresponding to the flexible shielding sheet cutting mechanism 121, a staggered spacing mechanism 123 located at the discharge end of the feeding track 120, and an assembly and transporting mechanism 124; the cutting and transporting mechanism 122 is used to press multiple flexible shielding sheets 2 onto the flexible shielding sheet cutting mechanism 121 and to transport the cut multiple flexible shielding sheets 2 onto the staggered spacing mechanism 123; the staggered spacing mechanism 123 is used to adjust the spacing of the multiple flexible shielding sheets 2 to be consistent with the spacing of each product on the flexible shielding sheet assembly loading seat 101; the assembly and transporting mechanism 124 is used to transport the multiple flexible shielding sheets 2 on the staggered spacing mechanism 123 onto the flexible shielding sheet assembly loading seat 101 and press the flexible shielding sheets 2 onto the sheet 1 in the flexible shielding sheet assembly loading seat 101 so as to fix the product when the pre-bundling PIN mechanism 102 is working. The feeding track 120 can be perpendicular to the system's infeed / outfeed direction. The misalignment and spacing mechanism 123 is located between the feeding track 120 and the pre-bundling PIN mechanism 102, used to match the spacing between the flexible shielding sheets 2 on the assembly and handling mechanism 124 with the spacing between the flexible shielding sheets 2 on the flexible shielding sheet assembly loading seat 101. The misalignment and spacing mechanism 123 can be implemented using existing technology, such as the arrangement trajectory spacing mechanism disclosed in Chinese Utility Model Patent CN219636279U, which only requires replacing its vacuum fixture with a positioning carrier capable of positioning the flexible shielding sheets 2; or, for example, the cam-driven spacing mechanism in Chinese Invention Patent Application CN116022536A, which only requires installing a positioning carrier capable of positioning the flexible shielding sheets 2 on its spacing head. The assembly and handling mechanism 124 can employ a robotic arm, which can be equipped with grippers or vacuum suction heads to pick up the flexible shielding sheets 2. The cutting and handling mechanism 122 can also adopt an existing structure, such as the terminal supply device disclosed in Chinese Utility Model Patent CN222573618U; or, it can adopt a structure similar to the steel mesh punching and handling robot in Chinese Utility Model Patent CN214391868U. The flexible shielding sheet cutting mechanism 121 corresponds to the punching die in the steel mesh punching and handling robot in Chinese Utility Model Patent CN214391868U, and the cutting and handling mechanism 122 corresponds to the robotic arm and vacuum suction head in the steel mesh punching and handling robot in Chinese Utility Model Patent CN214391868U. By replacing the robotic arm with a linear motor, the cutting and handling mechanism 122 and the assembly and handling mechanism 124 can share the same drive. The flexible shielding sheet cutting mechanism 121 is an existing cutting mechanism, for example, it can adopt the structure of the punching die in the steel mesh punching and handling robot in Chinese Utility Model Patent CN214391868U. Only the punch and die need to be adapted to the structure of the flexible shielding sheet 2.When the flexible shielding sheet 2 is conveyed to the flexible shielding sheet cutting mechanism 121 via the feeding track 120, the multiple flexible shielding sheets 2 are pressed together by the cutting and transporting mechanism 122. The flexible shielding sheet 2 is cut off from its material strip by the flexible shielding sheet cutting mechanism 121. Then, the cutting and transporting mechanism 122 transports the multiple cut flexible shielding sheets 2 to the staggered spacing mechanism 123. Since the spacing between each flexible shielding sheet 2 during cutting is the same as the spacing on the material strip, which is different from the spacing of each product on the flexible shielding sheet assembly loading seat 101, the staggered spacing mechanism 123 adjusts the spacing of the multiple flexible shielding sheets 2 to be consistent with the spacing of each product on the flexible shielding sheet assembly loading seat 101. Then, the assembly and transporting mechanism 124 transports the multiple flexible shielding sheets 2 on the staggered spacing mechanism 123 to the flexible shielding sheet assembly loading seat 101 and presses the flexible shielding sheets 2 onto the thin sheet 1 in the flexible shielding sheet assembly loading seat 101. Then, the pre-binding PIN mechanism 102 performs the PIN binding action.

[0041] In some specific embodiments, the PIN bundling module may further include a PIN bundling final pressing mechanism 125 located at the discharge end of the pre-bundling PIN mechanism 102. The PIN bundling final pressing mechanism 125 includes multiple upper riveting heads 126 and multiple lower riveting heads 127 corresponding to each other, as well as upper riveting head 126 drive and lower riveting head 127 drive that respectively drive the upper riveting heads 126 and lower riveting heads 127 to rise and fall. The upper riveting heads 126 and lower riveting heads 127 are respectively located above and below the inverted U-shaped support legs 21 of each product on the flexible shielding sheet assembly loading seat 101. The lower riveting head 127 has an adapter groove 130 that matches the inverted U-shaped support legs 21 of the bundled flexible shielding sheet 2. The flexible shielding sheet assembly loading seat 101 moves from the pre-bundling PIN mechanism 102 to the PIN bundling final pressing mechanism 125, and the PIN bundling final pressing mechanism 125 presses the inverted U-shaped support legs 21 after the pre-bundling PINs are further pressed, pressing back the springback that will occur after the pre-bundling PINs, so that it is tightly wrapped on the pins 11.

[0042] The metal parts assembly equipment includes a metal parts A feeding and cutting module 300, a metal parts B feeding and cutting module 301, a metal parts assembly loading seat 302, and an assembly and handling module 303 for transporting metal parts A and B from the metal parts A feeding and cutting module 300 and the metal parts B feeding and cutting module 301 to the metal parts assembly loading seat 302, respectively. The metal parts assembly loading seat 302 is used to position and support several products A and several products B, and can reciprocate along the system's feeding and discharging direction. A transfer and handling module 304 is provided between the flexible shielding sheet cutting and assembly equipment 100 and the metal parts assembly equipment for transporting products A and B from the flexible shielding sheet assembly loading seat 101 to the metal parts assembly loading seat 302. A robotic arm is also provided between the metal parts assembly equipment and the metal parts hot-melt equipment 400 for transferring products from the metal parts assembly equipment to the metal parts hot-melt equipment 400.

[0043] The assembly and handling module 303 can be equipped with a robotic arm. For example, the assembly and handling module 303 can be two sets of the above-mentioned cutting and handling mechanism 122 and assembly and handling mechanism 124; the metal part A loading and cutting module 300 and the metal part B loading and cutting module 301 can be flexible shielding sheet cutting mechanism 121. Only the picking parts of the cutting and handling mechanism 122 and the assembly and handling mechanism 124, and the cutting parts of the flexible shielding sheet cutting mechanism 121 need to be adapted to the specific structures of metal parts A and B.

[0044] The metal parts hot melting equipment 400 can adopt an existing structure, such as the Chinese utility model patent CN210046222U, a multi-faceted hot melting equipment. It is only necessary to replace the clamp with a hot melting carrier that reciprocates along the feeding and discharging direction of the system, and adjust the hot melting head according to the specific structural adaptability of product A and product B.

[0045] The transfer and handling module 304 can be a robotic arm, which can be equipped with grippers or vacuum suction heads to pick up products. The transfer and handling module 304 can be set at the discharge end of the PIN binding and final pressing mechanism 125 to transport the two products on the flexible shielding sheet assembly loading seat 101 to the metal parts assembly loading seat 302. After the two metal parts 3 are cut by the loading and cutting modules of their respective equipment, the assembly and handling module 303 places the two metal parts 3 onto the products on the metal parts assembly loading seat 302, and then heat-melts the two products through the metal parts heat-melting equipment 400. The heat-melting is to heat-melt the plastic parts on the sheet 1 to fix the metal parts 3 to the sheet 1.

[0046] A sheet 1 transfer module is provided between the discharge end of the sheet A testing equipment 200 and the sheet B testing equipment 201 and the feed end of the flexible shielding sheet cutting and assembly equipment 100. This module is used to transfer the sheet A and sheet B, which have been tested by the sheet A testing equipment 200 and the sheet B testing equipment 201 respectively, to the flexible shielding sheet assembly loading seat 101.

[0047] In some specific implementations, such as Figure 5 , Figure 11 and Figure 12As shown, both the sheet A inspection device 200 and the sheet B inspection device 201 may each include at least one sheet inspection and adjustment module 203. When there are multiple sheet inspection and adjustment modules 203, they are arranged sequentially along the feeding and discharging direction of the system. The sheet inspection and adjustment module 203 includes an inspection mechanism and an adjustment mechanism. The inspection mechanism is used to detect whether the angles of multiple pins 11 on the sheet 1 are consistent. The adjustment mechanism is used to adjust pins 11 at different angles to the same angle. The inspection mechanism includes a controller and a CCD inspection instrument 204 for taking pictures of the sheet 1. The adjustment mechanism includes an adjustment block 205 for pressing the sheet 1 above it and multiple top blocks 206 corresponding to all pins 11 of the sheet 1. Different top blocks 206 are driven to rise and fall by different motors. The CCD inspection instrument 204 acquires the angle value of each pin 11 and sends it to the controller. The controller calculates the adjustment value based on the angle value of the pin 11 acquired by the CCD inspection instrument 204 and transmits the adjustment value to the motor. The motor then drives the top block 206 to move the corresponding adjustment value. If the angle of a certain pin 11 is found to be acceptable, then the corresponding motor will not be adjusted. During adjustment, the adjusting block 205 descends to press and fix the sheet 1. Each top block 206 can correspond to multiple pins 11 of the sheet 1, or one top block 206 can correspond to one pin 11, which can be determined by the angle difference of the pins 11. When the angle difference of each pin 11 is relatively large, multiple sheet detection and adjustment modules 203 can be set, with each top block 206 corresponding to one pin 11; when the angle difference of each pin 11 is relatively small, only one sheet detection and adjustment module 203 can be set, with each top block 206 corresponding to multiple pins 11.

[0048] The first detection angle of the thin sheet 1 is detected by the CCD detector 204; an initial adjustment value is calculated based on the difference between the first detection angle and the preset target angle and the springback angle corresponding to the material of the thin sheet 1; the angle of the pin 11 is adjusted by the motor according to the initial adjustment value; the adjusted second detection angle is detected by the CCD detector 204; a second adjustment value is calculated based on the difference between the second detection angle and the target angle and the springback angle; the adjustment and detection steps are repeated until the difference between the Nth detection angle and the target angle falls within a set range, where N is an integer greater than 1; the sum of the N adjustment values ​​is superimposed to obtain the correspondence between the first detection angle and the adjustment value; the correspondence is corrected using an artificial intelligence algorithm so that for any first detection angle, the difference between the adjusted detection angle and the target angle falls within a set range; the corrected correspondence is stored in the memory; during the production stage, the controller retrieves the corresponding adjustment value from the memory based on the detection angle detected in real time by the CCD detector 204 and transmits it to the motor to adjust the angle of the pin 11; the artificial intelligence algorithm includes a neural network or deep learning model, which is trained using historical adjustment data to optimize the correspondence.

[0049] The method for the controller to calculate the adjustment value may include the following steps:

[0050] S101, Obtain the first detection angle θ1. The controller controls the CCD detector 204 to take pictures and analyze the current thin film 1 sample to obtain its initial angle θ1.

[0051] S102, Calculate and execute the initial adjustment value. The controller calculates the initial adjustment value ΔV1 according to the formula ΔV1=f(θ1-θ_target-α). Here, θ_target is the target angle, α is the springback angle corresponding to the material of sheet 1 (which can be obtained by consulting the corresponding manual), and the function f() represents a mapping function that converts the angle difference into the number of pulses or position commands required to drive the motor. The controller sends ΔV1 to the motor, and the motor drives the top block to move, performing the initial adjustment of sheet 1.

[0052] S103, obtain the second detection angle θ2. After adjustment, the controller controls the CCD detector 204 again to detect the angle of the thin film and obtain θ2.

[0053] S104, Judgment and Calculation. Calculate the deviation e2 = θ2 - θ_target. Determine whether |e2| is less than or equal to the preset accuracy threshold ε. If yes, proceed to step S106; otherwise, proceed to step S105.

[0054] S105, Calculate the second adjustment value. Calculate the second adjustment value ΔV2 according to the formula ΔV2=f(e2-α). Then, drive the motor to perform the adjustment action corresponding to ΔV2. Subsequently, the process returns to step S103, where the third detection angle θ3 is obtained, and the deviation e3 is calculated. This process is repeated iteratively.

[0055] S106, Recording and Overlaying. The iteration stops when the deviation e_N meets the accuracy requirement after the Nth detection. Calculate the total adjustment value V_total for this learning process: V_total = ΔV1 + ΔV2 + ... + ΔV_{N-1}. Record the data pair (θ1, V_total) as a learning sample point.

[0056] S107, Change the initial angle and repeat the learning process. Change the initial angle of the thin-slice sample manually or with an auxiliary device, and repeat steps S101 to S106 to obtain M different initial angles and their corresponding ideal total adjustment values, forming an initial correspondence dataset, where M is the number of learning samples.

[0057] S108, AI Model Training and Correction. The above dataset is input into an artificial intelligence algorithm module (e.g., a three-layer feedforward neural network) for training. The algorithm's input is the "first detection angle θ1," and its output is the predicted "total adjustment value V_pred." The training objective is to make the predicted value V_pred as close as possible to the true recorded value V_total. Through training, the AI ​​model learns the complex nonlinear mapping relationships of the entire system. Using the trained model, an optimized adjustment value V_opt can be generated for any input angle θ_x.

[0058] S109, Optimize the correspondence. Store the trained AI model parameters, or an "angle-adjustment value" lookup table generated by the model covering a continuous angle range, into the memory as the "corrected angle adjustment correspondence".

[0059] In actual production, the following steps are performed:

[0060] S201, Real-time Detection. During normal production, when a new sheet to be adjusted arrives at the workstation, the controller controls the CCD detector 204 to quickly detect its current angle θ_current.

[0061] S202, Query adjustment value. The controller retrieves or calculates the corresponding target adjustment value V_target from the "corrected angle adjustment correspondence" stored in memory, using θ_current as the index.

[0062] S203, Perform adjustment. The controller sends V_target to the motor, and the motor drive top block performs an adjustment action.

[0063] The thin-film inspection and adjustment module 203 may further include multiple thin-film 1 inspection carriers and a pushing mechanism 208 that moves each thin-film 1 inspection carrier towards the inspection mechanism and the adjustment mechanism. The inspection mechanism also includes an inspection block 209 for pressing the thin-film 1 above it and an adjustment mechanism 210 for driving the CCD inspector 204 to reciprocate towards the thin-film 1 inspection carrier. The inspection block 209 is height-adjustable. During inspection, the inspection block 209 lowers to press the thin-film 1, fixing it in place and ensuring the reliability of the data captured by the CCD inspector 204. The adjustment mechanism 210 is used to adjust the distance between the CCD inspector 204 and the thin-film 1 to accommodate focal length changes of different products.

[0064] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
