Description

Technical Field

[0001] This invention relates to the field of electronic component manufacturing technology, specifically to a BIN feeding machine for insertion and extraction force. Background Technology

[0002] In the manufacturing process of electronic components, insertion and extraction force is the most important indicator for evaluating the mechanical performance of electrical connectors. Insertion and extraction force are divided into insertion force and extraction force. Relevant standards have clearly defined the magnitude of insertion and extraction force for some electrical connectors. Electrical connectors rely on multiple pairs of contacts integrated within an insulator to transmit current. Whether the contacts make reliable contact directly affects the reliability and stability of the connector's transmission. If the insertion and extraction force of the contact pairs is too weak, poor contact or open circuits may occur after the connector is installed and used. If the insertion and extraction force is too high, problems such as inability to mate or damage to the connector components after repeated mating and extraction may occur. Therefore, all types of elastic contacts must undergo rigorous testing and sorting of insertion and extraction force before formal assembly.

[0003] With the rapid development of the electronics manufacturing industry, the production scale of electronic components such as connectors and terminals is constantly expanding, placing increasingly higher demands on product testing efficiency and automation levels. Traditional testing methods typically involve manual lifting and testing by operators one by one, which is not only inefficient and costly, but also highly susceptible to human error in terms of accuracy, failing to meet the demands of modern large-scale production for high-precision and high-efficiency testing. Therefore, a BIN (Binding Injection) blanking machine based on insertion and extraction force is proposed to address the aforementioned problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a BIN insertion and extraction force dividing blanking machine, which has the advantages of high automation and high detection accuracy. It solves the problem that traditional detection methods generally require operators to manually lift and inspect each item one by one, which is not only inefficient and costly, but also has detection accuracy that is greatly affected by human factors, and cannot meet the high-precision and high-efficiency detection requirements of modern large-scale production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a BIN insert / extraction force sorting and unloading machine, comprising a machine body, wherein a carrier return line is provided on the machine body and a jig misalignment module and a jig product unloading misalignment module are arranged sequentially along the conveying direction of the carrier return line. A jig loading / unloading module is provided on the upper side of the jig misalignment module and the jig product unloading misalignment module. An insert / extraction force detection mechanism corresponding to the jig loading / unloading module is also provided on one side of the machine body. A product unloading and empty tray handling module is provided on the side of the jig loading / unloading module away from the insert / extraction force detection mechanism. Two sets of receiving bin modules are provided below the product unloading and empty tray handling module, namely, an OK product receiving bin module and an NG product receiving bin module.

[0006] Furthermore, the jig misalignment module includes a first linear module, which is respectively provided with a manual loading position and a machine gripping unloading position, and each of the manual loading position and the machine gripping unloading position is provided with a first proximity switch.

[0007] Furthermore, the fixture loading and unloading module includes an XYZ three-axis moving module, and a hollow rotating platform is provided at the end of the XYZ three-axis moving module. Hydraulic grippers are installed on the hollow rotating platform.

[0008] Furthermore, the jig product unloading misalignment module includes a second linear module, on which a device gripping loading position and a device gripping unloading position are respectively provided. A second proximity switch is provided on both the device gripping loading position and the device gripping unloading position, and a photoelectric sensor is provided at the device gripping unloading position.

[0009] Furthermore, the product unloading and empty pallet handling module includes an XY moving module, which is equipped with a product retrieval module and an empty pallet retrieval module.

[0010] Furthermore, the product retrieval module is equipped with multiple suction nozzles, and the empty tray retrieval module is equipped with multiple suction cups.

[0011] Furthermore, each of the receiving hopper modules includes a third linear module and a lifting electric cylinder. The third linear module is located inside the machine body, and the lifting electric cylinder is mounted on the third linear module. A hopper is provided on the lifting electric cylinder, and a swivel station sensor photoelectric sensor is provided inside the hopper.

[0012] Furthermore, each of the receiving hopper modules contains multiple hoppers, which are arranged side by side along the moving direction of the third linear module.

[0013] Compared with the prior art, the present invention provides a BIN feeding machine with insertion and extraction force, which has the following beneficial effects: 1. This insertion and extraction force sorting and unloading machine automatically completes all processes from loading, handling, inspection, sorting into bins to unloading and tray replacement. Operators only need to place and remove fixtures at the front of the machine, which greatly improves the production efficiency of insertion and extraction force detection and sorting.

[0014] 2. This insertion and extraction force-based bin unloading machine has multiple bins in the OK product receiving bin module, each corresponding to a different insertion and extraction force bin range. This allows for precise classification and storage of products according to their insertion and extraction force values. The NG product receiving bin module also has multiple bins, which can be classified and collected according to different defect types. This meets the needs of high-quality production for product classification management. The two sets of receiving bin modules are arranged side by side below the product unloading and empty pallet handling modules, making full use of the space at the bottom of the equipment. The overall layout is compact and reduces the equipment's footprint.

[0015] 3. This insertion and extraction force-dividing BIN unloading machine utilizes a carrier return line to achieve automatic recycling of fixtures, reducing the labor intensity of manual handling. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 8 This embodiment describes a BIN sorting and unloading machine based on insertion and extraction force. This equipment is used to test the insertion and extraction force of electronic components (such as connectors and contacts) and automatically sorts and unloads the products into corresponding bins based on the test results, achieving full automation of the testing and BIN sorting and unloading process. The BIN sorting and unloading machine includes a body 6, on which a carrier return line 8 is installed. The carrier return line 8 is used to transport fixtures carrying the products, enabling the fixtures to circulate within the equipment.

[0020] In this embodiment, along the conveying direction of the carrier return line 8, a jig misalignment module 1 and a jig product unloading misalignment module 3 are sequentially arranged on the machine body 6. The jig misalignment module 1 is located in the front end area of ​​the carrier return line 8 and is used to receive jigs manually placed in or to send out empty jigs. The jig product unloading misalignment module 3 is located in the rear end area of ​​the carrier return line 8 and is used to receive empty jigs after products have been removed and transfer them to the lower return line for return. Above the jig misalignment module 1 and the jig product unloading misalignment module 3, a jig loading and unloading module 2 is provided. A insertion and extraction force detection mechanism 7 corresponding to the jig loading and unloading module 2 is also provided on one side of the machine body 6.

[0021] The fixture loading and unloading module 2 spans above the carrier return line 8. Its range of motion covers the area between the fixture misalignment module 1, the fixture product unloading misalignment module 3, and the insertion and extraction force detection mechanism 7. It is used to transport products between multiple workstations. The insertion and extraction force detection mechanism 7 is used to accurately measure the insertion force and extraction force of the product and transmit the detection data to the control system.

[0022] A product unloading and empty tray handling module 4 is located on the side of the fixture loading / unloading module 2 away from the insertion / extraction force testing mechanism 7. Below the product unloading and empty tray handling module 4 are two sets of receiving hopper modules 5. The product unloading and empty tray handling module 4 is used to transport the tested products from the fixture product unloading misalignment module 3 to the receiving hopper module 5 for tray placement, and is also responsible for the handling and replacement of empty trays. The two sets of receiving hopper modules 5 are designated as OK product receiving hopper modules and NG product receiving hopper modules. The OK product receiving hopper module stores products that have passed the insertion / extraction force test and can be further divided into BINs according to different insertion / extraction force ranges; the NG product receiving hopper module stores products that have failed the insertion / extraction force test.

[0023] Specifically, the fixture misalignment module 1 includes a first linear module 11, which is preferably a servo motor-driven lead screw module or a synchronous belt module, capable of linear movement along a direction perpendicular to the conveying direction of the carrier return line 8. The first linear module 11 is respectively equipped with a manual loading position 12 and an equipment gripping unloading position 13. The manual loading position 12 is located near the front of the equipment, where operators place the fixture carrying the product to be tested. The equipment gripping unloading position 13 is located near the inside of the equipment, where the fixture loading / unloading module 2 grips the product in the fixture.

[0024] It should be noted that both the manual feeding position 12 and the equipment gripping and unloading position 13 are equipped with a first proximity switch 14, which is used to detect the corresponding position and feed the signal back to the control system to control the movement and subsequent actions of the first linear module 11.

[0025] Specifically, the jig loading / unloading module 2 includes an XYZ three-axis moving module 21, which is composed of an X-axis linear module, a Y-axis linear module, and a Z-axis linear module, enabling linear motion in three spatial directions. A hollow rotating platform 22 is located at the end of the XYZ three-axis moving module 21. The hollow rotating platform 22 can rotate 360 ​​degrees around the Z-axis, facilitating adjustment of the product's posture to meet the gripping and releasing requirements of different workstations. A hydraulic gripper 23 is installed on the hollow rotating platform 22, which is used to clamp the product and has the advantages of stable clamping force and reliable operation.

[0026] Specifically, the fixture product unloading misalignment module 3 includes a second linear module 31. The second linear module 31 is also preferably a servo motor-driven linear motion mechanism that can move in a direction perpendicular to the conveying direction of the carrier return line 8. The second linear module 31 is respectively provided with a device gripping loading position 32 and a device gripping unloading position 33. The device gripping loading position 32 is close to the device gripping unloading position 13 and is used to receive the inspected products. The device gripping unloading position 33 is used for product unloading and for the empty tray handling module 4 to grip the products in the fixture.

[0027] It should be noted that both the feeding and unloading positions 32 and 33 of the equipment are equipped with second proximity switches 34 to detect whether the fixture is in place. In addition, a photoelectric sensor 35 is installed at the unloading position 33 to detect whether there is any product residue inside the fixture, ensuring complete unloading.

[0028] Specifically, the product unloading and empty tray handling module 4 includes an XY movement module 41, which consists of an X-axis linear module and a Y-axis linear module, enabling two-dimensional movement in the horizontal plane. The XY movement module 41 is equipped with a product picking module 42 and an empty tray picking module 43. The product picking module 42 has multiple suction nozzles for picking up products and placing them into the tray within the receiving hopper. The empty tray picking module 43 has multiple suction cups for picking up empty trays, thus achieving automatic tray replacement and handling.

[0029] Specifically, there are two sets of receiving hopper modules 5, with identical structures, used for receiving OK and NG products respectively. Each receiving hopper module 5 includes a third linear module 51 and a lifting electric cylinder 52. The third linear module 51 is located inside the machine body 6 and can move horizontally to move different hoppers 53 to the product unloading position. The lifting electric cylinder 52 is mounted on the third linear module 51 and has a hopper 53 on it. The hopper 53 is used to stack multiple trays, and the lifting electric cylinder 52 can drive the trays in the hopper 53 to rise and fall, so that the tray to be placed is always kept at a suitable height.

[0030] It should be noted that the hopper 53 is equipped with a tray-sloshing station sensor photoelectric 54, which is used to detect whether the tray is in place and the stacking status of the tray. Each set of receiving hopper modules 5 contains multiple hoppers 53, and the multiple hoppers 53 are arranged side by side along the moving direction of the third linear module 51.

[0031] In addition, for the OK product receiving module, each bin 53 corresponds to a different insertion / extraction force BIN range, such as a low insertion / extraction force zone, a low-to-medium insertion / extraction force zone, a medium-to-high insertion / extraction force zone, and a high insertion / extraction force zone, enabling fine-grained classification and storage of products. For the NG product receiving module, each bin 53 can correspond to different defect types (such as insertion / extraction force exceeding the upper limit, insertion / extraction force below the lower limit, appearance defects, etc.), facilitating subsequent classification and processing of defective products.

[0032] The working principle of the above embodiments is as follows: In use, the operator places the fixture carrying the product to be tested on the manual loading position 12 of the fixture misalignment module 1. After the first proximity switch 14 detects that the fixture is in place, it sends a signal to the control system. The first linear module 11 moves the fixture from the manual loading position 12 to the equipment gripping and unloading position 13, completing the initial positioning of the fixture. The XYZ three-axis moving module 21 of the fixture loading and unloading module 2 drives the hydraulic gripper 23 to move above the equipment gripping and unloading position 13 of the fixture misalignment module 1, gripping the product to be tested in the fixture and transporting it to the insertion and extraction force detection mechanism 7. The insertion and extraction force detection mechanism 7 accurately measures the insertion force and extraction force of the product, and the detection data is uploaded to the control system. After the detection is completed, the fixture loading and unloading module 2 retrieves the product.

[0033] If the product passes inspection, the fixture loading / unloading module 2 places the product back into the empty fixture flowing from the carrier return line 8. The fixture continues to move with the upper conveyor line to the equipment gripping and loading position 32 of the fixture product unloading misalignment module 3. After the second proximity switch 34 detects that the fixture is in place, the second linear module 31 moves the fixture from the equipment gripping and loading position 32 to the equipment gripping and unloading position 33. After the photoelectric sensor 35 detects and confirms that there is a product in the fixture, the next step is initiated.

[0034] The product unloading and empty tray handling module 4, driven by the XY moving module 41, moves to above the gripping position 33 of the fixture product unloading misalignment module 3. It then picks up the product through a suction nozzle and, based on the product's insertion / extraction force, sorts it into the BIN range, transporting it to the corresponding hopper 53 in the receiving hopper module 5 for tray placement. If a product fails inspection, it is similarly transported by the product unloading and empty tray handling module 4 to the corresponding hopper 53 in the NG product receiving hopper module.

[0035] During the tray placement process, when a tray is full of products, the empty tray module 43 removes the full tray from above the hopper 53 and places it in the designated position. The lifting electric cylinder 52 drives the hopper 53 to rise, sending the empty tray to the tray placement height. After the tray placement station photoelectric sensor 54 detects that the tray is in place, the equipment continues the tray placement operation. After the products are removed, the empty fixture is moved by the second linear module 31 of the fixture product unloading misalignment module 3 to the lower return line entrance of the carrier return line 8, and flows back to the front end of the equipment through the lower return line for manual loading, forming a circular flow of fixtures.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and concept of the present application, should be covered within the scope of protection of the claims of the present invention.
