Description

Technical Field

[0001] This utility model belongs to the field of probe crimping, specifically relating to a device used on automated logistics lines to achieve automatic crimping, positioning, and lighting of products. Background Technology

[0002] In the display module industry, LCD and OLED display modules often undergo aging performance testing at high temperatures before leaving the factory to improve product lifespan and stability. During this process, defective products are detected by connecting probes to power them on. However, currently, the industry largely relies on manual positioning and power-on for the post-aging product testing process. This manual connection method has many drawbacks; it is not only inefficient and unstable, but also prone to problems such as contact point breakage and misalignment, making risk management difficult. Utility Model Content

[0003] The purpose of this invention is to provide an automatic positioning and crimping device for logistics lines, so as to solve the problems of low efficiency and poor stability of manual crimping in the prior art, and realize automatic crimping test of products during and after aging.

[0004] This utility model discloses an automatic positioning and pressing device for a logistics line, comprising a probe module, a support fixture, a blocking cylinder, a positioning cylinder, and a lifting and pressing cylinder. The support fixture is used to securely carry the product and facilitate product transportation on the logistics line; the probe module and the support fixture cooperate to complete the pressing operation; the blocking cylinder is installed at the inspection station to stop the support fixture from transporting the product; the positioning cylinder precisely positions the stopped support fixture; and the lifting and pressing cylinder drives the probe module upward to achieve pressing and connection with the support fixture, thereby completing the product's electrical connection test.

[0005] As a further embodiment of this invention, the probe module comprises a fixing component, a PCB reference board, and multiple sets of probes. The fixing component effectively protects the PCB reference board and probes from external damage during use. The PCB reference board, as a core component, not only provides a stable mounting base for the probes, ensuring accurate probe positioning, but also plays a crucial role in signal transmission, ensuring data can be smoothly transmitted to the electrical testing equipment. Multiple sets of probes are soldered onto the PCB reference board and, during operation, maintain close contact with the support fixture. Precise crimping operations achieve circuit continuity, providing the necessary conditions for product testing.

[0006] As a further embodiment of this invention, the fixing assembly consists of an upper protective cover and a lower protective cover, which are independent components. The upper protective cover has through holes adapted to each set of probes, and the probes are installed in the through holes. This design allows sufficient slack to be reserved for the probes during compression, effectively preventing damage caused by excessive compression. The lower protective cover is located below the PCB probe board, protecting the PCB probe board from external damage; at the same time, it is indirectly fixed to the lifting and pressing cylinder through a machined part, providing reliable support for the lifting action of the probe module.

[0007] As a further aspect of this invention, an adapter plug is provided on the PCB public board. This plug is used to enable conduction between the wires and the electrical testing equipment, thereby completing the signal transmission test. In the design of the PCB public board, the probes adopt a redundant design scheme, with two probes installed for each output point. This design greatly improves the crimping continuity with the support fixture. Even if one probe fails, the other probe can still ensure normal circuit conduction, significantly improving the stability of the entire device operation.

[0008] As a further embodiment of this invention, a PCB motherboard with PAD contacts is mounted at the bottom of the support fixture. The PCB motherboard is electrically connected to the product via an adapter plug. This support fixture not only ensures stable transport of products on the logistics line but also allows for direct product testing on the fixture itself. The product can be placed flat on the surface of the support fixture, effectively ensuring stability during transportation and convenience of testing operations. Furthermore, the structure of the support fixture is carefully designed to ensure precise alignment of the PAD contacts on the PCB motherboard and the probes, significantly increasing the contact area between them. This achieves stable and reliable conductivity at the PCB / FPC test points, providing a solid guarantee for product testing.

[0009] As a further embodiment of this invention, the blocking cylinder, positioning cylinder, and lifting and pressing cylinder cooperate to complete the automatic pressing process. The blocking cylinder is installed at the inspection station on the logistics line. When the carrying fixture containing the product arrives at this station, the cylinder quickly extends and precisely stops the fixture, ensuring it remains stably in the designated inspection position. The positioning cylinder is located on the side of the carrying fixture. It activates immediately after the fixture stops, precisely adjusting to align the PAD points on the PCB motherboard of the carrying fixture with the probe contacts, ensuring a one-to-one correspondence. The lifting and pressing cylinder is securely connected to the probe module. After positioning, the cylinder exerts force to lift the probe module upwards, causing the probe to tightly contact the PAD copper contacts on the carrying fixture, completing the automatic lifting and pressing action. This establishes circuit contact continuity, allowing the product to be powered on smoothly, creating conditions for subsequent testing of parameters such as current, voltage, and power.

[0010] As a further aspect of this invention, in the probe module, the left-right spacing between adjacent probes is precisely set to 28mm, the diameter of a single probe reaches 4mm, and a flexible telescopic function is achieved through spring assembly. Simultaneously, the dimensions of the PAD copper contacts on the PCB motherboard are meticulously designed, with a length of 35mm and a width of 22mm, resulting in a single PAD contact area of ​​770mm². This design significantly expands the contact range between the probe and the PAD contacts, substantially increasing the force-bearing area between them, thereby effectively improving the accuracy and stability of circuit continuity and ensuring the reliability of product testing results.

[0011] This utility model has the following beneficial effects:

[0012] This utility model provides an automatic positioning and crimping device for logistics lines, which realizes automatic crimping test of products during and after aging.

[0020] The present invention will be further described below with reference to the accompanying drawings and relevant knowledge. Obviously, the described applications are only some embodiments of the present invention, and not all embodiments.

[0021] Reference Figures 1-6 As shown, this utility model discloses an automatic positioning and pressing device for a logistics line, which consists of a probe module, a bearing fixture 5, a blocking cylinder 8, a positioning cylinder 9, and a lifting and pressing cylinder 7.

[0022] The probe module consists of a fixing component, a PCB motherboard 4, and multiple sets of probes 2. The fixing component includes an upper protective cover plate 1 and a lower protective cover plate 3, which are independent components. The upper protective cover plate has through holes, and the probes are installed inside the protective plate, retaining a certain amount of slack during compression. An adapter plug is installed on the PCB motherboard 4 for the connection between the wires and the electrical testing equipment to perform signal transmission testing. The probes 2 are soldered onto the PCB motherboard 4 and employ a redundant design. A carrying fixture 5 mounts a PCB motherboard 6 with PAD contacts at its bottom and connects to the product via an adapter plug on the PCB motherboard 6. This fixture is characterized by its ability to carry products on the logistics line for transport and testing.

[0023] The system comprises multiple sets of cylinders: a blocking cylinder 8, a positioning cylinder 9, and a lifting and pressing cylinder 7. The blocking cylinder 8 is installed at the workstation requiring inspection and stops the fixture. The positioning cylinder 9 positions the stopped fixture, aligning the PCB probes with the PAD contacts. The lifting and pressing cylinder 7 lifts the PCB probes, automatically lifting and pressing them to achieve contact continuity and ultimately power-on of the product. Furthermore, when the fixture carrying the product is transported along the logistics line to the inspection station, the blocking cylinder activates first. Installed at a specific position at the inspection station, its piston rod quickly extends and precisely blocks the fixture's path. As the fixture continues to be transported, it eventually contacts the piston rod of the blocking cylinder. Under the blocking force, the fixture gradually decelerates and smoothly stops at the preset inspection position, providing a stable operating foundation for subsequent positioning and pressing processes and preventing fixture position deviation from affecting the accuracy of subsequent processes. After the fixture is successfully stopped, the positioning cylinder responds immediately. A positioning cylinder is mounted on the side of the fixture, with its piston rod extending towards the fixture and contacting its side. The lateral force applied by the piston rod pushes the fixture to make minute positional adjustments, ensuring precise alignment between the PCB motherboard on the fixture and the probe module below. During this process, the positioning cylinder ensures a one-to-one correspondence between the PAD contacts on the fixture and the probes on the PCB probe male board in the probe module, eliminating any slight misalignment that may occur during transport and providing precise positioning assurance for subsequent crimping. After positioning, the lifting crimping cylinder begins operation. The lifting crimping cylinder is indirectly fixed to the lower protective cover plate in the probe module via a machined component. Upon receiving a start signal, its piston rod extends upward, causing the entire probe module to rise synchronously. As the probe module rises, the probes on the PCB probe male board gradually approach the PAD contacts on the PCB motherboard at the bottom of the fixture, eventually making tight contact with them. Because the probe is spring-loaded and retractable, it is appropriately compressed under the continuous force of the lifting and pressing cylinder, ensuring a reliable electrical connection with the PAD contact. At this point, the probe connects to the electrical testing equipment via an adapter on the PCB probe connector, allowing the equipment to detect parameters such as current, voltage, and power, thus achieving a power-on test. After the test, the piston rod of the lifting and pressing cylinder retracts, causing the probe module to descend and separating the probe from the PAD contact. Next, the piston rod of the positioning cylinder retracts, releasing the positioning constraint on the fixture. Finally, the piston rod of the blocking cylinder retracts, clearing the fixture's path, allowing it to continue moving along the material line to the next process.

[0024] Specifically: The fixture refers to fixture 5, which carries products on the logistics line. Its bottom surface is equipped with a PCB motherboard 6, which has PAD copper contacts with a certain spacing. The PCB motherboard 6 also has plugs for connecting product cables, used for connection and communication between the product and the fixture. The probe module is a probe assembly that is pressed together with the fixture. The probe module is assembled from the bottom up: lower protective cover 3, PCB probe male board 4, and upper protective cover 1. The lower protective cover refers to the insulating protective plate below the PCB probe male board 4. Its function is to indirectly fix it to the lifting and pressing cylinder 7 through the processing parts and to protect the PCB probe male board from damage. The PCB probe board structure consists of multiple sets of probes and PCB boards. Probes 2 are soldered to the PCB male board 4 for communication. The left and right spacing between each set of probes is 28mm, and each probe has a diameter of 4mm. The probes are assembled by springs. The PCB board has two probes installed in each channel for connection. An adapter plug is also installed on the PCB probe board for data transmission testing with electrical testing equipment. A protective cover 1 has through holes for each probe group, designed to fit inside the probe 2 and protect it from damage. The cylinder assembly includes a blocking cylinder 8, a positioning cylinder 9, and a lifting and pressing cylinder 7. The blocking cylinder 8 is installed at the testing station and stops the fixture. The positioning cylinder 9 positions the stopped fixture, aligning the PCB probe with the PAD contacts on the fixture. The lifting and pressing cylinder 7 lifts the probe PCB, automatically lifting and pressing to achieve contact connection and ultimately power-on of the product.

[0025] The purpose of this invention is to enable automatic crimping and power-on testing of products during and after aging by using cylinder positioning on a fixture. The probe module is easy to assemble, and the probe 2 features a dual-needle design, effectively improving the crimping conductivity with the fixture. The fixture can carry the product and transport it on the logistics line. This fixture design allows for flat placement of the product while simultaneously transporting it on the logistics line for a series of tests. Furthermore, the product is transported to the testing station via the fixture 5. The positioning cylinder 9 positions the fixture 5, and the lifting cylinder 7 drives the probe module to crimp with the fixture, completing the conductivity between the probe module and the fixture's PAD copper sheet, thereby achieving conductivity with the product.

[0026] Furthermore, the probe module consists of multiple probes 2, a PCB board 4, an upper protective cover 1, and a lower protective cover 3; the upper protective cover 1 and the lower protective cover 3 are fixed on the upper and lower parts of the probe PCB board respectively, and are detachably connected together to protect the PCB probe board from external force damage.

[0027] On the PCB public board 4, two probes 2 are installed for each output point. The distance between each group of probes 2 is 28mm, and there are a total of 17 groups of contacts. The number of output points on the PCB board is designed according to the actual situation.

[0028] For the fixture, its assembly involves mounting a PCB board 6 with PAD points on the bottom of the fixture 5. For example, the PCB copper contact is 35mm long and 22mm wide, and the area of ​​a single PAD contact is 770mm². In other words, the crimping device probe 2 can contact the PAD contacts of the fixture PCB board 6 over a large area, increasing the force-bearing area, thereby accurately achieving the continuity of the test points on the PCB / FPC, and thus achieving the continuity of the product, thereby achieving the purpose of positioning and testing on the logistics line.

[0029] For the cylinder, the blocking cylinder 8 is installed at a detection station on the logistics line to stop the fixture of the currently transported product, so as to carry out the following process; then the side positioning cylinder 9 will position the fixture, so that the PAD point of the fixture PCB board 6 is aligned with the contact point of the probe 2, so that each group of probes corresponds to the PAD point one by one, and finally the lifting cylinder 7 drives the probe 2 to press and position itself with the fixture PCB board 6.

[0030] Example 1: Refer to Figure 1-4 The automatic positioning and pressing device of this utility model consists of a support fixture 5, a probe module and a cylinder assembly.

[0031] The bottom of the support fixture 5 is equipped with a PCB motherboard 6, which has PAD copper contacts distributed at specific intervals and plugs for connecting product cables, enabling conductive connection between the product and the support fixture 5. With this design, the support fixture 5 can smoothly transport products on the logistics line and accurately deliver them to the inspection station.

[0032] The probe module consists of a lower protective cover plate 3, a PCB probe board 4, an upper protective cover plate 1, and multiple sets of probes 2. The lower protective cover plate 3, located below the PCB probe board 4, serves as an insulating protective structure. On one hand, it is indirectly fixed to the lifting and pressing cylinder 7 via a machined component, providing stable support for the lifting action of the probe module; on the other hand, it effectively protects the PCB probe board 4 from external damage. Multiple sets of probes 2 are soldered onto the PCB probe board 4, with a 28mm spacing between adjacent probes. Each probe has a diameter of 4mm and is spring-loaded for telescopic movement, facilitating tight contact with the PAD contacts on the support fixture 5. Furthermore, the PCB probe board 4 is equipped with an adapter plug for connecting electrical testing equipment to achieve data transmission testing. The upper protective cover plate 1 has through holes adapted to each set of probes 2, allowing the probes 2 to be fitted within them. This prevents damage to the probes from external forces and allows for reasonable allowance during probe compression.

[0033] The cylinder assembly includes a blocking cylinder 8, a positioning cylinder 9, and a lifting and pressing cylinder 7. The blocking cylinder 8 is installed at the inspection station on the logistics line. When the carrier fixture 5 carrying the product is transported to this station, the blocking cylinder 8 extends, precisely stopping the carrier fixture 5. Subsequently, the positioning cylinder 9 activates, precisely adjusting and positioning the stopped carrier fixture 5 to ensure that the PAD points on the PCB motherboard 6 of the carrier fixture 5 correspond one-to-one with the contacts of the probe 2. Finally, the lifting and pressing cylinder 7 drives the probe module upward, causing the probe 2 to tightly adhere to the PAD copper contacts on the carrier fixture 5, completing the automatic lifting and pressing operation, achieving contact continuity, and thus powering the product for testing parameters such as current, voltage, and power.

[0034] In practical applications, the number and spacing of probes in the probe module, as well as the layout of PAD contacts on the support fixture 5, can be flexibly adjusted according to the characteristics and testing requirements of different products, so as to adapt to the testing requirements of diverse products.

[0035] Improved crimping efficiency and stability: The cylinder assembly enables automatic stopping, positioning, and crimping of the load-bearing fixture, eliminating the need for manual operation and greatly improving crimping efficiency. At the same time, it avoids problems such as point disconnection and misalignment caused by manual operation, effectively improving the stability of crimping and reducing risks during product testing.

[0036] Improved continuity reliability: The probe module adopts a dual-needle redundancy design, with one output point corresponding to two probes. Even if one probe fails, the other can still maintain continuity, which greatly improves the crimping continuity with the support fixture and ensures the accuracy of product testing.

[0037] Easy to assemble and maintain: The upper and lower protective covers of the probe module are detachable, which facilitates the installation, maintenance and replacement of the PCB board and probes; the structural design of the support fixture and cylinder assembly also facilitates assembly and debugging, reducing equipment maintenance costs.

[0038] Adaptable to automated production: This device can be used in conjunction with automated logistics lines to realize the automatic delivery and inspection of products on the logistics line, meeting the needs of automated production in the display module industry and improving production efficiency and product quality.
