Description

Technical Field

[0001] This utility model relates to the field of hot press testing and production technology, and in particular to an auxiliary mechanism and testing device for testing the flatness of the heating plate of a hot press. Background Technology

[0002] A hot press is a device that heats two pre-fluxed, tin-plated parts to a temperature sufficient to melt and flow the solder, forming a permanent electromechanical connection between the parts and the solder after solidification. Because the flatness requirements for the surface pressed by a hot press are high, the flatness inspection of the hot press's heating plate is particularly important. Currently, the industry standard is to directly press lead strips onto the heating plate and then assess the flatness of the heating plate by measuring the thickness difference of different parts of the lead strip after pressing. However, this method has significant drawbacks: firstly, the soft nature of lead strips makes them prone to adhesion to the heating plate surface during pressing, easily deforming during subsequent separation; secondly, traditional inspection methods lack positioning and protection measures for the lead strips, making them susceptible to secondary deformation during handling and inspection. These factors severely affect the accuracy of the final measurement data, leading to deviations in the flatness assessment results. Furthermore, existing inspection devices lack systematic solutions for lead strip transport and inspection, resulting in low inspection efficiency and inconvenient operation. Utility Model Content

To this end, this invention proposes an auxiliary mechanism and testing device for testing the flatness of a heating plate in a hot press, which has the advantages of improving the positioning stability of the lead strip and reducing deformation during handling.

[0004] In a first aspect, an auxiliary mechanism for testing the flatness of a heating platen in a hot press, according to an embodiment of the present invention, includes: The support component is provided with a receiving groove, the receiving groove having an opening, the receiving groove being used to place the lead strip to be tested, and the opening allowing the lead strip to pass through; The transfer module is detachably connected to the support component and is used to transport the support component.

[0005] An auxiliary mechanism for testing the flatness of a heating plate in a hot press, according to an embodiment of this utility model, has at least the following beneficial effects: This application, through the synergistic action of the support component and the transfer module, forms a complete protective transfer system after the lead strip is subjected to pressure testing. The open design of the receiving groove allows the lead strip to be transferred directly along with the support component after testing without peeling it off, avoiding secondary deformation caused by direct contact with the lead strip in traditional methods. The detachably connected transfer module enables synchronous mechanized handling of the support component and the lead strip, eliminating deformation of the lead strip caused by manual operation and ensuring that the lead strip maintains its original shape after pressure during transfer through physical isolation between mechanisms. The size-adaptive design of the receiving groove ensures the stability of the lead strip's positioning and allows for non-destructive detachment of the lead strip after testing through the open structure, forming a closed-loop protection mechanism of testing-transfer-inspection.

[0006] According to an embodiment of the present invention, an auxiliary mechanism for testing the flatness of a heating plate of a hot press is provided, wherein a positioning groove is provided at the bottom of the receiving groove, and the positioning groove is used to receive the lead strip to be tested.

The translation component can drive the thickness detector to move along the length direction of the lead strip, and the thickness detector is used to detect the thickness of the lead strip.

[0011] A flatness testing device for a hot press heating plate according to an embodiment of this utility model has at least the following beneficial effects: This application solves the problem of deformation of lead strips due to their soft material by coordinating the auxiliary mechanism, the transfer platform, and the detection module. The support component in the auxiliary mechanism fixes the lead strip through a receiving groove, and the transfer module moves the support component from the transfer platform to the detection position, avoiding direct contact with the lead strip and preventing deformation. The transfer platform provides a stable detection environment for the lead strip, ensuring that the lead strip does not shift during the detection process. The detection module drives the thickness detector to move along the length of the lead strip through a translation component, realizing continuous automated measurement of the thickness of the lead strip at different positions. Combined with the positioning groove and the detection mark, it accurately corresponds to the flatness data of each area of ​​the heating plate. The entire device replaces manual operation with mechanical handling, reducing the risk of secondary deformation of the lead strip, and improves detection efficiency and consistency through the directional movement of the translation component.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Reference Figures 1 to 2 This utility model embodiment provides an auxiliary mechanism for testing the flatness of a heating plate in a hot press, including a support 100 and a transfer module. The support 100 is provided with an open receiving groove 110 for placing lead strips, and the transfer module is detachably connected to the support 100 to realize the handling function.

[0023] Specifically, the lead strip is pre-placed in the receiving groove 110 for hot-press testing. After the test, the transfer module picks up the support 100 and transfers it to the testing station. Because the lead strip remains physically constrained within the receiving groove 110, its shape is effectively protected during the transfer. The open structure allows the testing equipment to directly contact the lead strip surface for thickness measurement without removing the lead strip from the support 100. The mechanized handling process eliminates vibration or tilting caused by manual operation, ensuring that the lead strip maintains its original shape after being compressed.

[0024] Compared to existing technologies, traditional methods require manual handling of lead strips using tools such as tweezers, inevitably generating contact stress. This solution establishes a comprehensive protection mechanism for the lead strip from testing to inspection by physically isolating the support component 100 from the transfer module. In existing technologies, the lead strip is exposed to an open environment; this solution creatively employs a closed transfer system, fundamentally blocking external interference factors. This application effectively prevents deformation of the lead strip during transfer, ensuring that thickness measurement data accurately reflects the flatness of the heating plate. After testing, the lead strip can be automatically transferred without manual intervention, significantly improving testing efficiency while avoiding measurement errors caused by contact operations in traditional methods.

[0025] According to some embodiments of this application, a positioning groove 120 is provided at the bottom of the receiving groove 110, and the positioning groove 120 is used to receive the lead strip to be tested.

[0026] Specifically, when the lead strip is placed in the receiving groove 110, its bottom is embedded in the positioning groove 120. The side wall of the positioning groove 120 contacts the side of the lead strip, forming a physical constraint that restricts the horizontal movement of the lead strip. During the process of the transfer module handling the support 100, the lead strip cannot be laterally offset or twisted due to the constraint of the positioning groove 120, thus maintaining its original shape. When the lead strip is compressed, the depth design of the positioning groove 120 can prevent the lead strip from undergoing vertical deformation due to gravity, while the opening structure does not affect the subsequent removal of the lead strip from the transfer platform 200.

[0027] Compared to existing technologies, traditional lead strip testing devices simply place the lead strip on a flat surface, which makes it prone to slippage or warping during transport, leading to deviations in test data. This solution adds a bottom positioning groove 120, maintaining convenient lead strip placement and removal while utilizing the groove structure for bidirectional positioning, eliminating the risk of lead strip displacement, effectively suppressing positional shifts and morphological changes during the testing process, avoiding thickness measurement errors caused by lead strip deformation, and ensuring the accuracy of heating plate flatness test results.

[0028] According to some embodiments of this application, a plurality of positioning grooves 120 are spaced apart along the width direction of the receiving groove 110.

[0029] Specifically, the lead strips are embedded in independent positioning grooves 120, each groove 120 providing circumferential constraint to the lead strips and preventing lateral displacement due to thermal expansion or external forces during hot pressing. The spacing creates physical isolation between adjacent lead strips, eliminating the risk of compression deformation caused by contact. The positioning grooves 120, arranged along the width, ensure that the lead strips cover the lateral detection area of ​​the heating plate, guaranteeing that the detection module 400 can collect lead strip thickness data at different lateral positions, forming a complete flatness evaluation benchmark.

[0030] Compared to existing technologies, which typically stack lead strips directly within the receiving groove 110 without physical isolation, leading to sticking or displacement of the lead strips after heating, this solution uses spaced positioning grooves 120 to create independent receiving spaces. This ensures the lead strips maintain a fixed posture during hot pressing, avoiding deformation errors caused by displacement or contact. This achieves precise positioning of the lead strips during hot pressing, eliminates the influence of contact deformation between lead strips on the test data, ensures the lead strip thickness data accurately reflects the flatness of the heating plate, and optimizes the distribution density and uniformity of the lead strips in the test area, improving the reliability of the flatness test results.

[0031] According to some embodiments of this application, a plurality of detection marks 130 are provided along the radial direction of the positioning groove 120.

[0032] Specifically, detection markers 130 are radially spaced along positioning grooves 120 to form discrete positioning points. Thickness detectors 420 move along the detection markers 130 at preset intervals via translation components 410, performing step-by-step scanning. Each detection marker 130 corresponds to a thickness measurement point at a different radial position on the lead strip. A spatial correspondence is established between the marker coordinates recorded by the system and the thickness data. This method replaces manual visual positioning, eliminates measurement point offsets caused by operator subjective judgment, and ensures consistency between the spatial position of the detection path and the deformation area of ​​the lead strip in each detection.

[0033] Compared to existing technologies, traditional methods rely on operator experience to determine the location of measurement points, which is susceptible to visual errors leading to data deviations. This solution establishes a standardized measurement coordinate system using mechanically constrained detection markers 130, enabling the thickness detector 420 to perform systematic scanning according to a preset program. This avoids random errors caused by manual intervention, achieving precise positioning of the lead strip thickness detection points, eliminating positioning deviations caused by manual operation, ensuring that the measurement data accurately reflects the actual thickness changes of the lead strip at different radial positions, and improving the reliability of the heating plate flatness assessment results.

[0034] According to some embodiments of this application, the transfer module includes a three-axis moving component and a gripping component, the gripping component being detachably connected to the three-axis moving component, and the gripping component being able to grip the support 100; or, the transfer module is a six-axis robot.

[0035] Specifically, the three-axis moving assembly moves along the X, Y, and Z axes under preset program control, positioning the gripping assembly to the target position of the support 100. The gripping assembly then executes the gripping action after detecting the clamping force via sensors, preventing deformation of the lead strip due to excessive external force. When a six-axis robot is used, its end effector adjusts its posture through path planning algorithms, ensuring the support 100 remains horizontal throughout the transfer process, reducing the risk of deformation of the lead strip due to tilted forces. Both solutions replace manual operation with automated handling, eliminating lead strip displacement or compression problems caused by improper operation during handling.

[0036] Compared with existing technologies, traditional methods rely on manual handling of the support component 100, which is prone to deformation of the lead strip due to uneven force or path deviation by the operator. However, this application ensures that the support component 100 is subjected to uniform force and has a precise movement trajectory during the grasping, moving and placing process through the programmed motion control of a three-axis moving component or a six-axis robot, thereby avoiding changes in the shape of the lead strip and solving the problem of deformation of the lead strip due to the inflexibility of the mechanical structure during the transfer process. Through the coordinated control of automated positioning and clamping actions, the stability of the handling process is improved, while reducing manual intervention and improving operational efficiency.

[0037] This application further proposes a flatness testing device for a hot press heating plate, including an auxiliary mechanism for testing the flatness of the hot press heating plate, a transfer platform 200 adjacent to the transfer module, and a detection module 400 composed of a translation component 410 and a thickness detector 420. The transfer platform 200 is used to place the support 100, and the translation component 410 is disposed on the transfer platform 200 and connected to the thickness detector 420, which can drive the thickness detector 420 to move along the length direction of the lead strip to detect its thickness.

[0038] Specifically, after the support component 100 secures the lead strip via the receiving groove 110, the transfer module transfers it to the transfer platform 200. The translation component 410 drives the thickness detector 420 to move at a constant speed along the length of the lead strip, continuously collecting thickness data during the movement. Because the lead strip is confined within the receiving groove 110, and the transfer process uses mechanical clamping rather than direct contact with the lead strip, the risk of deformation caused by manual operation is avoided. The transfer platform 200 provides a stable reference plane for the detection module 400, ensuring that the movement trajectory of the thickness detector 420 remains parallel to the axis of the lead strip, thereby improving the spatial consistency of the measurement data.

[0039] Compared to existing technologies, traditional methods require manual operation when removing lead strips, which can easily cause deformation and result in highly random detection positions. This solution eliminates human interference through mechanical transport and automated detection path planning. Furthermore, the use of a 410 translational component for directional movement detectors ensures repeatability and full-length coverage in thickness measurement, resolving the deformation problem caused by manual handling. Automated detection path control enables continuous and accurate measurement of lead strip thickness, thereby improving the reliability of heating plate flatness assessment data.

[0040] According to some embodiments of this application, the transfer module is detachably connected to an adsorption component 300, which is capable of adsorbing lead strips.

[0041] The adsorption component 300 refers to a device that fixes the lead strip by negative pressure or magnetic attraction. Specifically, it can be implemented by a vacuum chuck 320 or an electromagnetic chuck 320. The surface of the chuck 320 is covered with a flexible material to disperse contact stress and avoid indentation on the surface of the lead strip.

[0042] Specifically, the adsorption component 300 adsorbs the lead strip surface through negative pressure, and the transfer module drives the adsorption component 300 to transfer the lead strip from the heating plate to the support 100. During the adsorption process, the lead strip only bears a uniformly distributed negative pressure, avoiding the localized compression deformation caused by traditional mechanical clamping. The detachable connection structure between the adsorption component 300 and the transfer module allows for changing the layout of the suction cups 320 according to the size or shape of the lead strip. For example, a single row of suction cups 320 can be used for long, narrow lead strips, while a matrix of suction cups 320 can be used for large-area lead sheets. After the lead strip is transferred, the adsorption component 300 can be moved to a standby position with the transfer module or replaced with other functional modules.

[0043] Compared to existing technologies, traditional lead strip transfer methods rely on grippers directly contacting both sides of the lead strip. The clamping force can easily cause deformation at the edges or concavity in the center. In contrast, the adsorption component 300 uses non-contact negative pressure adsorption, resulting in a uniformly distributed contact area and avoiding localized stress concentration. Existing fixed adsorption devices cannot accommodate lead strips of different sizes, while the detachable adsorption component 300 allows for quick changes in the suction cup 320 layout according to the lead strip size, improving the device's adaptability and solving the deformation problem caused by mechanical clamping during lead strip transfer. This ensures the lead strip maintains its original shape after transfer, thereby improving the accuracy of thickness measurement data. The detachable design of the adsorption component 300 further expands the device's compatibility with different specifications of lead strips, reducing measurement errors caused by changes in lead strip size.

[0044] According to some embodiments of this application, such as Figure 3 As shown, the adsorption assembly 300 includes a mounting bracket 310 and suction cups 320, with multiple suction cups 320 distributed in a matrix on the mounting bracket 310.

[0045] Specifically, the mounting bracket 310 is machined to form a flat bearing surface, and the suction cups 320 are fixed to the bracket at a preset position via threaded connection or snap-fit. When the adsorption component 300 contacts the lead strip, the matrix-distributed suction cups 320 simultaneously generate negative pressure adsorption force. The adsorption range of each suction cup 320 is limited to a local area of ​​the lead strip, and multiple suction cups 320 work together to form an adsorption network covering the entire surface of the lead strip. The adsorption force on each area of ​​the lead strip is dynamically balanced by the spacing and number of suction cups 320, avoiding localized concentrated force that could cause material stretching or compression deformation.

[0046] Compared to existing technologies, traditional adsorption devices typically employ a single suction cup 320 or a linear arrangement of suction cups 320, concentrating the adsorption force in the center area of ​​the lead strip, leading to warping at the edges due to insufficient force. This application utilizes a matrix layout to evenly distribute the adsorption force across the lead strip surface, maintaining its original shape before thickness measurement. This solves the problem of deformation caused by uneven force during adsorption, ensuring the lead strip remains flat during transport and providing a stable test object for subsequent thickness measurement.

[0047] According to some embodiments of this application, the detection module 400 further includes an identification component, and the support 100 is provided with a detection mark 130, and the identification component is able to obtain information from the detection mark 130.

[0048] Specifically, after the transfer module places the support 100 on the transfer platform 200, the identification component first scans the detection mark 130 at the end of the lead strip to determine the initial position of the lead strip. As the translation component 410 drives the thickness detector 420 to move along the lead strip, the identification component continuously scans the detection marks 130 along the way, automatically linking the thickness data with the position information. Through the automatic matching of the detection mark 130 and the identification component, precise binding of the "position-thickness" data is achieved, improving testing efficiency by more than 50% while avoiding human error. This is particularly suitable for high-volume, high-precision heating plate flatness testing scenarios.
