Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a device for synchronously detecting the hole type, hole spacing and hole diameter of a copper busbar assembly. Background Technology

[0002] Copper busbar assemblies are crucial conductive connection components in power distribution equipment. They typically require bending, punching, and other processing according to circuit design to form the busbar assembly. The precision of the holes (hole spacing, hole diameter, hole shape) on the copper busbar assembly directly affects the installation fit and conductive contact performance with electrical components such as circuit breakers and disconnect switches. If the hole spacing or hole shape is not up to standard, it can lead to installation difficulties, reduced contact area, increased contact resistance, and even serious safety hazards such as localized overheating and sparks.

[0003] Currently, the inspection of copper busbar assembly hole positions relies heavily on manual measurement using traditional measuring tools such as calipers and plug gauges. This method of manually measuring hole spacing and diameter one by one is time-consuming and labor-intensive, making it difficult to meet the needs of modern mass production. The inspection results heavily depend on the experience and sense of responsibility of the operators, and are prone to misjudgment and omissions due to visual fatigue or negligence. Furthermore, the inspection standards may differ between different operators, and even between the same operator at different times, making it difficult to guarantee the consistency and impartiality of the inspection results. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to overcome the problem that in the existing technology, manual measurement of hole spacing and hole diameter is time-consuming and labor-intensive, which is difficult to meet the needs of modern mass production, and the test results are heavily dependent on the experience and sense of responsibility of the operators, and are prone to misjudgment and missed detection due to visual fatigue or negligence, a device for synchronous detection of hole type, hole spacing and hole diameter of copper busbar assembly is provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a synchronous detection device for hole type, hole spacing and hole diameter of copper busbar assembly, including a frame and a transmission mechanism, a detection mechanism and a picking mechanism arranged on the frame. The transmission mechanism is used to transport the copper busbar assembly, the detection mechanism is used to detect the hole spacing and hole type of the copper busbar assembly, and the picking mechanism is used to pick up the copper busbar assembly on the transmission mechanism, transfer it to the detection mechanism, and return it to the transmission mechanism after the detection is completed. The testing mechanism includes a testing base and several testing components. The holes on the testing components and the copper busbar components correspond one-to-one. The testing base has a testing cavity on its side. The testing components include an upper testing rod and a lower testing rod arranged in the testing cavity. The upper testing rod is elastically connected to the mounting base, and the lower testing rod is elastically connected to the mounting base. The upper testing rod is located above the lower testing rod. The copper busbar components are automatically picked up and transported by the picking mechanism. The testing mechanism automatically completes the synchronous testing of hole spacing and hole shape. The testing speed is fast and the accuracy is high. Using the contact and separation states of the upper and lower detection rods under elastic connection as the judgment basis, when the copper busbar assembly hole is qualified, the upper and lower detection rods can smoothly pass through the copper busbar assembly hole and restore contact, thus issuing a qualified signal. This detection method is intuitive, reliable, easy to implement and low in cost. In the initial state, the upper and lower detection rods are in contact.

[0006] To address the issue of how the acquisition mechanism can accurately place or remove the copper busbar assembly from the detection position without interference during the detection process, a further feature is provided: a clearance cavity is provided on the top surface of the detection seat, which is connected to the detection cavity, and the clearance cavity is used for the acquisition mechanism to pass through.

[0007] To address the issue of how to achieve elastic movement of the detection rod, enabling accurate detection while avoiding damage from rigid collisions with the copper busbar assembly, the detection assembly further includes an upper elastic element and a lower elastic element. An upper mounting groove is provided at the top of the detection cavity, and a lower mounting groove is provided at the bottom of the detection cavity. The upper detection rod is slidably arranged within the upper mounting groove, and the upper elastic element is also arranged within the upper mounting groove. One end of the upper elastic element is fixedly connected to the upper detection rod, and the other end is fixedly connected to the bottom of the upper mounting groove. The lower detection rod is slidably arranged within the lower mounting groove, and the lower elastic element is also arranged within the lower mounting groove. One end of the lower elastic element is fixedly connected to the lower detection rod, and the other end is fixedly connected to the bottom of the lower mounting groove.

[0008] To address the issue of how to smoothly guide and align the detection rod when it initially enters the copper busbar assembly hole, avoiding jamming or generating erroneous signals due to minor deviations, the invention further includes an upper guide head that retracts inward from top to bottom at the end of the upper detection rod near the lower detection rod, and a lower guide head that retracts inward from bottom to top at the end of the lower detection rod near the upper detection rod.

[0009] To address the layout issue between the testing and transmission mechanisms, the design further includes placing the testing mechanism on top of the transmission mechanism.

[0010] To address the challenge of automating and precisely transferring copper busbar assemblies between the transmission and inspection mechanisms in three dimensions, a further assembly includes an ingestion mechanism comprising an adsorption head, a lifting drive, a lateral drive, and a longitudinal drive. The longitudinal drive is fixedly connected to the frame and provides power for the movement of the adsorption head along the transmission direction of the transmission mechanism. The output end of the longitudinal drive is connected to the lateral drive, and the output end of the lateral drive is connected to the lifting drive. The lateral drive provides power for the lateral movement of the adsorption head toward or away from the inspection mechanism. The output end of the lifting drive is connected to the adsorption head and provides power for the adsorption head to move toward or away from the copper busbar assemblies transported on the transmission mechanism.

[0011] The beneficial effects of this utility model are: the synchronous detection device for hole shape, hole spacing and hole diameter of copper busbar assembly provided by this utility model can automatically grab and transfer copper busbar assembly through the picking mechanism, and automatically complete the synchronous detection of hole spacing and hole shape through the detection mechanism. The detection speed is fast and the accuracy is high. Using the contact and separation states of the upper and lower detection rods under elastic connection as the basis for judgment, when the copper busbar assembly hole position is qualified, the upper and lower detection rods can smoothly pass through the copper busbar assembly hole position and restore contact, thus issuing a qualified signal. This detection method is intuitive, reliable, easy to implement, and low in cost. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] like Figure 1This is a schematic diagram of the structure of the present invention. A device for synchronously detecting the hole type, hole spacing and hole diameter of a copper busbar assembly includes a frame 1 and a transmission mechanism 2, a detection mechanism 3 and a picking mechanism 4 arranged on the frame 1. The transmission mechanism 2 is used to transport the copper busbar assembly 5. The detection mechanism 3 is used to detect the hole spacing and hole type of the copper busbar assembly 5. The picking mechanism 4 is used to pick up the copper busbar assembly 5 on the transmission mechanism 2, transfer it to the detection mechanism 3, and return it to the transmission mechanism 2 after the detection is completed. like Figure 2 , 3 As shown, the detection mechanism 3 includes a detection seat 31 and several detection components 32. The detection components 32 correspond one-to-one with the holes on the copper busbar assembly 5. The detection seat 31 has a detection cavity 311 on its side. The detection component 32 includes an upper detection rod 321 and a lower detection rod 322 arranged in the detection cavity 311. The upper detection rod 321 is elastically connected to the mounting base, and the lower detection rod 322 is elastically connected to the mounting base. The upper detection rod 321 is located above the lower detection rod 322. The copper busbar assembly is automatically gripped and transported by the picking mechanism 4. The detection mechanism 3 automatically completes the synchronous detection of hole spacing and hole shape. The detection speed is fast and the accuracy is high. Using the contact and separation states of the upper and lower detection rods 421 and 422 under elastic connection as the judgment basis, when the copper busbar assembly hole position is qualified, the upper and lower detection rods 421 and 422 can smoothly pass through the copper busbar assembly hole position and restore contact, and send out a qualified signal. This detection method is intuitive, reliable, easy to implement and low cost. By setting multiple detection components 42, multi-hole synchronous rapid detection is realized, and the detection results are objective and accurate, which greatly improves production efficiency and product quality control level. In the initial state, the upper detection rod 321 and the lower detection rod 322 are in contact.

[0017] like Figure 4 As shown, the top surface of the detection seat 31 is provided with a clearance cavity 312, which is connected to the detection cavity 311. The clearance cavity 312 is used for the intake mechanism 4 to pass through. By setting the clearance cavity 312, the intake mechanism 4 is provided with operating space, ensuring the smoothness of the transfer process and the positioning accuracy, and guaranteeing the repeatability of the detection and the reliability of the device operation.

[0018] like Figure 2 , 3As shown, the detection assembly 32 includes an upper elastic element 323 and a lower elastic element 324. An upper mounting groove 313 is provided on the top of the detection cavity 311, and a lower mounting groove 314 is provided on the bottom of the detection cavity 311. The upper detection rod 321 is slidably arranged in the upper mounting groove 313, and the upper elastic element 323 is arranged in the upper mounting groove 313. One end of the upper elastic element 323 is fixedly connected to the upper detection rod 321, and the other end is fixedly connected to the bottom of the upper mounting groove 313. The lower detection rod 322 is slidably arranged in the lower mounting groove 314. Inside the mounting groove 314, the lower elastic element 324 is arranged. One end of the lower elastic element 324 is fixedly connected to the lower detection rod 322, and the other end is fixedly connected to the bottom of the lower mounting groove 314. The upper and lower elastic elements 323 and 324 are springs. Through the specific arrangement of the upper and lower elastic elements 323 and 324, a stable and reliable elastic reset function is provided for the detection rod, which not only ensures the sensitivity and accuracy of the detection, but also plays a buffer protection role and extends the service life of the device.

[0019] like Figure 2 , 3 As shown, the upper detection rod 321 has an upper guide head 3211 that tapers inward from top to bottom at the end near the lower detection rod 322, and the lower detection rod 322 has a lower guide head 3221 that tapers inward from bottom to top at the end near the upper detection rod 321. The upper and lower guide heads 3211 and 3221 can be arc-shaped or conical. The design of the upper and lower guide heads 3211 and 3221 allows the end of the detection rod to slide smoothly into the hole when it contacts the copper busbar assembly, which plays a good guiding and centering role, reduces the alignment accuracy requirements of the detection process, and improves the success rate and reliability of the detection.

[0020] like Figure 1 As shown, the testing mechanism 3 is arranged on the transmission mechanism 2, which is a conveyor belt. By directly arranging the testing mechanism 3 on the transmission mechanism 2, the equipment layout is optimized, the transfer path of the copper busbar components is shortened, the testing cycle time is further improved, and the equipment integration is higher.

[0021] like Figure 1As shown, the ingestion mechanism 4 includes an adsorption head 41, a lifting drive 42, a lateral drive 43, and a longitudinal drive 44. The longitudinal drive 44 is fixedly connected to the frame 1. The longitudinal drive 44 provides power for the adsorption head 41 to move along the transmission direction of the transmission mechanism 2. The output end of the longitudinal drive 44 is connected to the lateral drive 43. The output end of the lateral drive 43 is connected to the lifting drive 42. The lateral drive 43 provides power for the lateral movement of the adsorption head 41 to move closer to or away from the detection mechanism 3. The output end of the lifting drive 42 is connected to the adsorption head 41. The lifting drive 42 provides power for the adsorption head 41 to move closer to or away from the copper busbar assembly 5 transported on the transmission mechanism 2. Through the combination of the lifting, lateral, and longitudinal drives, a series of complex actions such as gripping, moving, positioning, and placing the copper busbar assembly can be reliably completed. It is the core execution unit for realizing fully automatic detection.

[0022] The suction head 41 can be composed of a vacuum generator and a vacuum suction cup, using compressed air to generate a vacuum through the vacuum generator and connecting a vacuum suction cup made of materials such as silicone or polyurethane. Alternatively, it can be composed of a vacuum pump and a vacuum suction cup, providing a vacuum source through a central vacuum pump and connecting to the suction cup through pipelines and solenoid valves.

[0023] The lifting drive 42, the lateral drive 43 and the longitudinal drive 44 can all be electric push rods, electric cylinders, lead screw transmission mechanisms (composed of servo motors and ball screws) or sliding mechanisms (guide rails and sliders to support and guide the movement and driven by motors or cylinders).

[0024] Working process: The copper busbar assembly 5 to be inspected is placed on the transmission mechanism 2, which transports it to the designated acquisition station; The ingestion mechanism 4 starts working, and the longitudinal drive 44 and the transverse drive 43 work together to move the adsorption head 41 directly above the copper busbar assembly 5; then, the lifting drive 42 drives the adsorption head 41 to descend and grab the copper busbar assembly 5 by vacuum adsorption or other means; next, the lifting drive 42 lifts the copper busbar assembly, and the transverse drive 43 and the longitudinal drive 44 work together again to accurately transfer the copper busbar assembly 5 to the plane where the center of the detection cavity 311 of the detection seat 31 of the detection mechanism 3 is located. Each test hole on the copper busbar assembly 5 is aligned with the lateral position of its corresponding test component 32. Driven by the lateral drive component 43, the copper busbar assembly 5 moves laterally, its upper surface contacting the upper guide head 3211 of the upper test rod 321. Under pressure, the upper test rod 321 is compressed upwards, and the upper elastic element 323 is compressed. Simultaneously, the lower surface of the copper busbar assembly 5 contacts the lower guide head 3221 of the lower test rod 322, and the lower test rod 322 is compressed downwards, compressing the lower elastic element 324. The copper busbar assembly continues to move laterally. If the hole position is qualified (the hole spacing and hole diameter meet the requirements), the ends of all the upper and lower detection rods 321 and 322 will be able to pass smoothly through the holes on the corresponding copper busbar assembly. All detection components 32 will have contact signals at the same time. After the detection is completed, the copper busbar assembly 5 moves laterally out of the detection chamber 311. The upper detection rod 321 moves downward under the restoring force of the upper elastic element 323, and the lower detection rod 322 moves upward under the restoring force of the lower elastic element 324, until the two resume contact. Each detection component 32 is equipped with a sensor (such as a contact sensor, photoelectric sensor, etc., not shown in the figure) to detect whether the upper and lower detection rods 321 and 322 are in contact. If the upper and lower detection rods of all detection components 32 successfully restore contact and generate a signal, the copper busbar component 5 hole position is determined to be qualified.

[0025] If any one or more detection components 32's upper or lower detection rods 321 and 322 cannot pass through the hole due to hole spacing deviation, hole diameter being too small, or hole shape being incorrect (such as tilting), or cannot restore contact after passing through, then the corresponding detection component 32 will have no signal, and the system will determine that the copper busbar component 5 is unqualified. After the inspection is completed, the ingestion mechanism 4 operates again, lifting the copper busbar assembly 5 from the inspection mechanism 3 and transferring it back to the transmission mechanism 2. Based on the inspection results, the transmission mechanism 2 can transport qualified and unqualified products to different collection areas, completing automatic sorting.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
