Description

Technical Field

[0001] This application relates to the field of electronic product testing technology, and in particular to a flattening device and electronic product testing equipment. Background Technology

[0002] Currently, in the production process of some electronic products (such as chips), visual inspection modules (such as CCD cameras; CCD stands for charge coupled device, and a CCD camera is a digital camera with a charge coupled device image sensor) are required for related inspections.

[0003] Specifically, when an electronic product moves under the vision inspection module, the optical inspection lens of the vision inspection module focuses on the surface of the product to be inspected, generating a clear image for product inspection. However, due to the inconsistent coefficients of thermal expansion between materials, electronic products experience significant warping deformation after soldering and baking. This warping deformation prevents the optical inspection lens from focusing on the surface to be inspected, resulting in blurred images and affecting the accuracy of the inspection.

[0004] Therefore, how to avoid affecting the accuracy of product testing due to warping and deformation of electronic products is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this application is to provide a flattening device and an electronic product testing equipment, which solves the problem that the warping and deformation of electronic products affects the accuracy of product testing.

[0006] To achieve the above objectives, this application provides a flattening device, comprising:

[0007] A mounting bracket is used to secure the product when it moves along the first direction to a position below the vision inspection module.

[0008] The pressure claws are used to hold the product on the mounting base, so that the product is flat and fits the mounting base.

[0009] A power unit, connected to the pressure claw, is used to drive the pressure claw to move in a second direction to press or release the product.

[0010] In some embodiments, the mounting base is provided with a vacuum suction cup, which is used to generate an adsorption force when the product moves along the first direction to the underside of the vision inspection module, thereby fixing the product to the mounting base.

[0011] In some embodiments, the power component is a cylinder assembly, and the flattening device further includes:

[0012] The control valve is located in the air path of both the cylinder assembly and the vacuum suction cup. The control valve is used to control the vacuum suction cup to adsorb the product and the cylinder assembly to close so that the pressure claw presses the product when a first control signal is received. It is also used to control the vacuum suction cup to release the adsorption force and release the product when a second control signal is received, and to control the cylinder assembly to open so that the pressure claw disengages from the product.

[0013] The controller is connected in communication with the control valve and is used to transmit the first control signal and the second control signal to the control valve.

[0014] In some embodiments, the flattening device further includes a fixed bracket, which is detachably connected to a single-sided track for conveying the product. The fixed bracket is used to fix the power component so that the power component is located on the side of the single-sided track away from the fixed seat.

[0015] In some embodiments, the fixing bracket includes:

[0016] The connecting frame is U-shaped, with hanging ears at both ends. Both hanging ears are connected to the single-sided track via detachable connectors.

[0017] The connecting plate, located within the connecting frame, is used to securely install the power components.

[0018] In some embodiments, the pressure claw includes a pressure head and a connecting portion. The connecting portion includes a first connecting body and a second connecting body. The first connecting body is used to connect the telescopic end of the power assembly. The second connecting body is located between the first connecting body and the pressure head. The first connecting body, the second connecting body, and the pressure head form a clearance groove, which is used to avoid the single-sided track of the conveying product.

[0019] In some embodiments, the first connecting body, the second connecting body, and the pressure head are integrally formed, and the first connecting body, the second connecting body, and the pressure head are C-shaped.

[0020] In some embodiments, the flattening device further includes a travel limit block, which is fixedly installed on the fixed end of the power component. The travel limit block is used to abut against the pressure claw when the telescopic end of the power component extends, so as to limit the movement of the pressure claw.

[0021] In some embodiments, the pressure claw is provided with a limiting groove, and the travel limiting block includes a limiting protrusion, which is slidably disposed in the limiting groove.

[0022] This application also provides an electronic product testing device, including the flattening device described above.

[0023] Compared to the aforementioned background technology, the flattening device provided in this application includes a fixed base, pressure claws, and a power assembly. The fixed base secures the product when it moves along a first direction to below the vision inspection module. The pressure claws press down on the product on the fixed base, ensuring the product is flat and conforms to the fixed base. The power assembly is connected to the pressure claws and drives them to move along a second direction to press or release the product. It can be seen that when the product moves along the first direction to below the vision inspection module, the fixed base first secures the product, and then the power assembly provides power to move the pressure claws along the second direction to press down on the product. This allows the warped product to flatten and conform to the fixed base, enabling the optical inspection lens of the vision inspection module to focus on the surface of the product to be tested, generating a clear image for accurate product inspection. This flattening device, with the combined action of the fixed base and pressure claws, ensures the product flattens and conforms to the fixed base, achieving clear imaging and accurate inspection results, thus solving the problem of warped deformation of electronic products affecting the accuracy of product inspection.

[0044] The flattening device provided in this application includes a fixed base 10, a pressure claw 20, and a power assembly 30.

[0045] The mounting base 10 has a flat support surface and is used to fix the product when the product moves along the first direction to the bottom of the vision inspection module.

[0046] The pressure claw 20 is used to press the product on the fixed base 10, so that the product is flat and fits against the flat support surface of the fixed base 10, so as to form a test plane that can be clearly imaged by the visual inspection module.

[0047] The power assembly 30 is connected to the pressure claw 20. The power assembly 30 is used to drive the pressure claw 20 to move in the second direction to press or release the product. Of course, the power assembly 30 can be a power telescopic assembly, and the movement of the pressure claw 20 in the second direction can be achieved through the telescopic movement of the power telescopic assembly.

[0048] It should be noted that the first direction and the second direction can be adjusted according to the actual conveying direction of the product and the pressure direction of the gripper. The first direction can be horizontal, and the second direction can be perpendicular to the first direction. In this way, the product can be flat and attached to the flat support surface of the fixed seat 10 by the downward pressing movement of the gripper 20.

[0049] As can be seen, when the product moves along the first direction to the bottom of the vision inspection module, the product is first fixed by the fixing seat 10, and then the power component 30 provides power so that the pressure claw 20 moves along the second direction to press the product. In this way, the warped and deformed product can be flat and fit against the fixing seat 10, and the optical inspection lens of the vision inspection module can focus on the test plane of the product to produce a clear image, so as to achieve accurate inspection of the product.

[0050] The flattening device, with the combined action of the fixed base 10 and the pressure claw 20, can make the product flat and fit against the fixed base 10, thereby achieving clear imaging and accurate test results, and solving the problem of affecting the accuracy of product testing due to the warping and deformation of electronic products.

[0051] To facilitate product fixation, a vacuum suction cup is provided inside the fixing base 10. The vacuum suction cup is flush with the flat support surface of the fixing base 10. The vacuum suction cup is used to generate suction force when the product moves along the first direction to the bottom of the vision inspection module, so that the product is fixed to the fixing base 10.

[0052] For example, when the product moves along the first direction to the bottom of the vision inspection module, the vacuum solenoid valve is opened by controlling the vacuum suction cup to open the vacuum, generating an adsorption force to fix the product to the fixing seat 10.

[0053] In some embodiments, the power assembly 30 is a cylinder assembly, and further, the flattening device also includes a control valve and a controller.

[0054] The control valve is located in the air path of both the cylinder assembly and the vacuum suction cup. When the first control signal is received, the control valve controls the vacuum suction cup to adsorb the product and the cylinder assembly to close so that the pressure claw 20 presses the product. When the second control signal is received, the control valve controls the vacuum suction cup to release the adsorption force and the cylinder assembly to open so that the pressure claw 20 leaves the product. The controller is communicatively connected to the control valve and is used to transmit the first control signal and the second control signal to the control valve.

[0055] Of course, depending on actual needs, the control valve can be a solenoid valve. During the operation of the equipment, the controller sends a control signal to energize the solenoid valve, thereby controlling the state of the solenoid valve. After the state of the solenoid valve changes, it controls the opening and closing of the cylinder assembly and the vacuum suction cup.

[0056] Specifically, when the product moves along the first direction to below the vision inspection module, the controller sends a first control signal to the control valve, causing the control valve to open. This opens the air passages for both the cylinder assembly and the vacuum suction cup, allowing air to enter. This causes the vacuum suction cup to open a vacuum, and the telescopic end of the cylinder assembly to retract. The vacuum suction cup generates suction force, fixing the product to the fixed base 10. The retracted telescopic end of the cylinder assembly then drives the pressure claw 20 downwards to press the product, ultimately making the product flat and adhered to the flat support surface of the fixed base 10. After the product inspection is completed, the controller sends a second control signal to the control valve, causing the control valve to close. This closes the air passages for both the cylinder assembly and the vacuum suction cup, causing the vacuum suction cup to close a vacuum. The telescopic end of the cylinder assembly extends, and the suction force disappears, releasing the product from the fixed base 10. The extended telescopic end of the cylinder assembly then drives the pressure claw 20 upwards to leave the product, allowing the product to continue being transported along the first direction. The working principles of vacuum suction cups and cylinder assemblies can be found in existing technologies, and will not be elaborated here.

[0057] To facilitate the fixing of the power assembly 30 (cylinder assembly), the flattening device also includes a fixing bracket 40, which is detachably connected to the single-sided track 60 for conveying the product (the so-called single-sided track 60 refers to a single track in a double-sided track for conveying the product, which extends along a first direction). The fixing bracket 40 is used to fix the power assembly 30 so that the power assembly 30 is located on the side of the single-sided track 60 away from the fixing seat 10.

[0058] Specifically, the fixed bracket 40 includes a connecting frame 41 and a connecting plate 43. The connecting frame 41 is U-shaped, and both ends of the connecting frame 41 are provided with hanging ears 42. Both hanging ears 42 are connected to the single-sided track 60 by detachable connectors (such as bolts or screws). The connecting plate 43 is located inside the connecting frame 41 and is used to fix the power assembly 30.

[0059] In some embodiments, the pressure claw 20 includes a pressure head 21 and a connecting portion 22. The connecting portion 22 includes a first connecting body 221 and a second connecting body 222. The first connecting body 221 is used to connect the telescopic end of the power assembly 30. The second connecting body 222 is located between the first connecting body 221 and the pressure head 21. The first connecting body 221, the second connecting body 222, and the pressure head 21 form a clearance groove 23, which is used to avoid the single-sided track 60 for conveying products.

[0060] The first connecting body 221, the second connecting body 222, and the pressure head 21 are integrally formed and are C-shaped. This creates a C-shaped clearance groove 23, which avoids interference with the downward-moving pressure claw 20 when the pressure claw 20 performs its pressing action, thus preventing interference with the product-flattening function.

[0061] To facilitate limiting the stroke of the pressure claw 20, the flattening device also includes a stroke limit block 50, which is fixedly installed on the fixed end of the power component 30. The stroke limit block 50 is used to abut against the pressure claw 20 when the telescopic end of the power component 30 extends, so as to limit the movement of the pressure claw 20.

[0062] In some embodiments, the pressure claw 20 is provided with a limiting groove 24, and the travel limiting block 50 includes a limiting protrusion 51, which is slidably disposed in the limiting groove 24.

[0063] It is understandable that the aforementioned stroke limiting block 50 can be an L-shaped structure, with the limiting protrusion 51 serving as a hook structure for the stroke limiting block 50. Correspondingly, the side of the pressure claw 20 is provided with a limiting groove 24, which can be U-shaped. The U-shaped limiting groove 24 slides in conjunction with the limiting protrusion 51. In other words, the upper end of the stroke limiting block 50 has a limiting protrusion 51 that can be slidably embedded in the U-shaped limiting groove 24 of the pressure claw 20. When the cylinder is opened, the pressure claw 20 rises, and the lower surface of the limiting protrusion 51 contacts the lower inner wall of the U-shaped limiting groove 24, preventing the pressure claw 20 from continuing to move upward. This achieves the purpose of limiting the stroke of the pressure claw 20. This design allows the entire cylinder assembly and the pressure claw 20 to be installed in some narrow spaces.

[0064] Compared to the fixed stroke of a regular cylinder, the design of limiting the stroke of the pressure claw 20 allows for adjustment of the operating distance difference of the pressure claw 20 according to requirements, thus meeting the equipment's needs for installation space, stability, and safety.

[0065] In addition, the flattening device can also be equipped with a pressure sensor. The pressure sensor is used to detect the status of the cylinder assembly or the pressure generated by the cylinder assembly. The pressure sensor is connected to the controller. In this way, by detecting the status of the cylinder assembly or the pressure claw 20 in real time, it can monitor whether the cylinder assembly is lifting and lowering normally, thereby ensuring that when the cylinder assembly is closed, it drives the pressure claw 20 to move downward and press on the product, so that the pressure claw 20 provides sufficient pressure to make the product fit against the flat support surface of the fixed seat 10.

[0066] In summary, when the product moves along the first direction to the bottom of the vision inspection module, the product is first fixed by the fixing seat 10, and then the power component 30 provides power so that the pressure claw 20 moves along the second direction to press the product. In this way, the warped and deformed product can be flat and fit against the fixing seat 10. After that, the optical inspection lens of the vision inspection module can focus on the test plane of the product, resulting in clear imaging and accurate inspection results.
