Description

Technical Field

[0001] This utility model relates to a dispensing detection mechanism, and more particularly to a double-sided dispensing detection mechanism for a gas leak sensor. Background Technology

[0002] A double-sided dispensing inspection mechanism for gas leak sensors refers to a mechanism that performs dispensing operations on both sides of the sensor during the gas leak sensor production process and inspects the quality of the dispensing. This inspection mechanism typically involves aspects such as sensor manufacturing processes, quality control, and potential troubleshooting. Regarding quality control, it means that the quality of the dispensing needs to be inspected after each dispensing to ensure that there are no problems such as leakage, insufficient dispensing, or excessive dispensing. However, for gas leak sensors requiring double-sided inspection, current technology does not have a continuous production line to ensure the continuous execution of double-sided dispensing and inspection. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide a double-sided dispensing detection mechanism for a gas leak sensor. This mechanism utilizes a dual-station tooling fixture mounted on a turntable, and is designed with a layout comprising a peripheral height limiting section, a central UV adhesive detection section, a pin misalignment photographing detection section, a dispensing section, a dispensing detection section, a flipping section, a height limiting section, a dispensing section, a dispensing detection section, and a central UV adhesive detection section. This allows for an automated and continuous double-sided dispensing and thorough detection process for the gas leak sensor after positioning and loading, resulting in higher production efficiency and better stability.

[0004] This utility model provides the following technical solution:

[0005] A double-sided dispensing detection mechanism for a gas leak sensor includes a positioning and material handling part for gripping and feeding the gas leak sensor into a turntable. The turntable is driven by a motor to rotate around a central fixed plate in increments. Multiple sets of tooling fixtures are evenly arranged on the turntable along the circumference. The turntable is also arranged in sequence around the turntable as follows: a height limiting part 1, a central UV glue detection part 1, a pin misalignment photograph detection part 1, a dispensing part 1, a dispensing detection part 1, a flipping part, a height limiting part 2, a dispensing part 2, a dispensing detection part 2, and a central UV glue detection part 2.

[0006] Both the height limiting part one and the height limiting part two include a pressure block driven by a height limiting pressure cylinder. The pressure block is used to press the product in the tooling fixture before dispensing to ensure that the product is placed in place. The center UV glue detection part one and the center UV glue detection part two are used to take pictures to detect whether the UV glue at the center position of the product is missing. The pin misalignment photo detection part one is used to take pictures to detect whether the pins on the product are missing or misaligned. The dispensing part one and the dispensing part two are used to dispense glue to the line grooves on the product. The dispensing detection part one and the dispensing detection part one are used to take pictures to detect whether the line grooves of the product have been dispensed. Each tooling fixture has two sets of workstation slots arranged side by side. A fixed top pressure block is arranged on one side of the workstation slot, and a floating top pressure block pressed by a spring is arranged on the other side. The central fixed plate is also equipped with a pull cylinder for pressing the floating top pressure block away from the fixed top pressure block when the product is loaded, flipped and unloaded.

[0007] Thus, by setting up a dual-station tooling fixture on the turntable, and in conjunction with the surrounding height limiting unit 1, center UV glue detection unit 1, pin misalignment photographing detection unit 1, dispensing unit 1, dispensing detection unit 1, flipping unit, height limiting unit 2, dispensing unit 2, dispensing detection unit 2, and center UV glue detection unit 2, the gas leak sensor after positioning can automatically and continuously complete the double-sided dispensing and thorough detection process, resulting in higher production efficiency and better stability.

[0008] Preferably, the fixed top pressure block is screwed onto the tooling fixture and has two sets of side pressure end blocks that press against one side of the product. The floating top pressure block is slidably mounted on the tooling fixture, with one side pressing against a spring and the other side having two sets of side pressure end blocks that press against the other side of the product. The side pressure end blocks are rectangularly distributed to improve the positioning stability of the product. The floating top pressure block also has a set of positioning blocks. The drive end of the pull cylinder is provided with a set of pull rods, and the end of the pull rods is provided with two sets of side edges to simultaneously press the positioning blocks away from the fixed top pressure block.

[0009] Preferably, the first central UV glue detection unit, the first pin misalignment photographic detection unit, the first dispensing detection unit, the second dispensing detection unit, and the second central UV glue detection unit all include a detection camera for photographic detection, and the dispensing machine includes a dispensing head and a dispensing linear module for driving the dispensing head to move in the X, Y, and Z directions. The dispensing head dispensing technology is existing technology and will not be described in detail here.

[0010] Preferably, the flipping section includes a flipping gripper for clamping the product and flipping it 180°, a linear module for driving the flipping gripper to move back and forth between two sets of workstation slots, and a push cylinder for pushing the linear module to drive the flipping gripper to rise and fall. Therefore, the flipping gripper can be raised after clamping the product to facilitate the subsequent 180° flipping.

[0011] Preferably, the positioning and material handling unit includes two sets of transition transport grippers and a transport drive module for synchronously transferring the two sets of transition transport grippers. One set of transition transport grippers is used to grip and transport the product to the rotary positioning assembly. The rotary positioning assembly includes a rotary carrier for accommodating the product and a rotary motor for driving the rotary carrier to rotate. A positioning camera for taking pictures and positioning the product on the rotary carrier is also arranged on one side. The other set of transition transport grippers is used to synchronously grip and transfer the product on the rotary carrier to the transition transfer assembly. The transition transfer assembly includes a transition carrier for positioning the product and a transition linear module for transferring the transition carrier to the loading end of the second transition transport assembly. The second transition transport assembly includes a second set of transition transport grippers for gripping the product and a transport drive module for driving the second set of transition transport grippers to the tooling fixture above the loading end of the turntable.

[0012] Among them, the first transport drive module adopts the existing quick-change drive module, which can achieve fast and accurate transport effect. The two ends of the transport mounting frame in this quick-change drive module are used to symmetrically install two sets of transition transport grippers. When the transport motor drives the transport shaft to rotate 180°, it can drive the transport mounting frame, which is connected to the tail end of the transport shaft, to move horizontally and vertically in sync. The lateral guide of the transport mounting frame is limited by the lateral guide rail to ensure that the transport mounting frame does not rotate.

[0013] The second transport drive module uses a transport cylinder to facilitate the linear reciprocating motion of the second transport gripper between the loading end of the turntable and the unloading end of the transition transfer component. The transport cylinder and the second transport gripper are also driven to lift and lower via a lifting cylinder for lifting, clamping and placing products.

[0014] Thus, during the feeding process, the addition of a rotary positioning component and a transition transfer component enables synchronous photo-taking and positioning of products fed onto the turntable during the conveying process. Simultaneously, the rotary motor used to rotate the rotating carrier provides the function of rotating misaligned products back into position after photo-taking detection. Even with the added positioning function on the product feeding line, the synchronous cooperation of the transition transfer component, transition handling component one, and transition handling component one ensures that the feeding efficiency is not affected, allowing the product feeding line to achieve stable and efficient synchronous operation.

[0015] The beneficial effects of this utility model are as follows: In this testing mechanism, by setting the tooling fixture with two workstations on the turntable, and in conjunction with the structural layout of the surrounding height limiting part one, the central UV glue detection part one, the pin skew photography detection part one, the dispensing part one, the dispensing detection part one, the flipping part, the height limiting part two, the dispensing part two, the dispensing detection part two, and the central UV glue detection part two, the gas leakage sensor after positioning and loading can automatically and continuously complete the double-sided dispensing and full detection process, resulting in higher production efficiency and better stability.

[0016] Furthermore, during the feeding process, the addition of rotary positioning components and transition transfer components allows for simultaneous photo-taking and positioning of products fed onto the turntable during the conveying process. Simultaneously, the rotary motor used to rotate the rotating carrier can rotate misaligned products back into position. Even with the addition of positioning functions to the product feeding line, the synchronous cooperation of the transition transfer components, transition handling components, and transition handling components ensures that the feeding efficiency is not affected, enabling the product feeding line to achieve stable and efficient synchronous operation.

[0028] like Figure 1-8 As shown, a double-sided dispensing detection mechanism for a gas leak sensor, in this embodiment, includes a positioning and material handling part for clamping and feeding the gas leak sensor into a turntable. The turntable is driven by a motor to rotate around a central fixed plate in increments. Multiple sets of tooling fixtures are evenly arranged on the turntable along the circumference. The turntable is also arranged in sequence around the turntable as follows: a height limiting part 1, a central UV glue detection part 1, a pin skew photography detection part 1, a dispensing part 1, a dispensing detection part 1, a flipping part, a height limiting part 2, a dispensing part 2, a dispensing detection part 2, and a central UV glue detection part 2.

[0029] Both height limiting section one and height limiting section two include a pressure block driven by a height limiting pressure cylinder. The pressure block is used to press against the product in the tooling fixture before dispensing to ensure that the product is placed in place. Center UV glue detection section one and center UV glue detection section two are used to take pictures to detect whether the UV glue at the center position of the product is missing. Pin misalignment photo detection section one is used to take pictures to detect whether the pins on the product are missing or misaligned. Dispensing section one and dispensing section two are used to dispense glue to the wire grooves on the product. Dispensing detection section one and dispensing detection section one are used to take pictures to detect whether the wire grooves on the product have been dispensed. Each tooling fixture has two sets of workstation slots arranged side by side. A fixed top pressure block is arranged on one side of the workstation slot, and a floating top pressure block pressed by a spring is arranged on the other side. The central fixed plate is also equipped with a pull cylinder for pressing the floating top pressure block away from the fixed top pressure block when the product is loaded, flipped and unloaded.

[0030] Thus, by setting up a dual-station tooling fixture on the turntable, and in conjunction with the surrounding height limiting unit 1, center UV glue detection unit 1, pin misalignment photographing detection unit 1, dispensing unit 1, dispensing detection unit 1, flipping unit, height limiting unit 2, dispensing unit 2, dispensing detection unit 2, and center UV glue detection unit 2, the gas leak sensor after positioning can automatically and continuously complete the double-sided dispensing and thorough detection process, resulting in higher production efficiency and better stability.

[0031] The fixed top pressure block is screwed onto the tooling fixture and has two sets of side pressure end blocks 1 that press against one side of the product. The floating top pressure block is slidably mounted on the tooling fixture, with one side pressing against the spring and the other side having two sets of side pressure end blocks 2 that press against the other side of the product. The side pressure end blocks 1 and 2 are rectangularly distributed to improve the positioning stability of the product. The floating top pressure block also has a set of positioning blocks. The drive end of the pull cylinder is provided with a set of pull rods, and the ends of the pull rods are provided with two sets of side edges to synchronously press the positioning blocks away from the fixed top pressure block.

[0032] The Central UV Glue Inspection Department 1, Pin Skew Photography Inspection Department 1, Dispensing Inspection Department 1, Dispensing Inspection Department 2, and Central UV Glue Inspection Department 2 all include inspection cameras for photographic inspection, and the dispensing machine includes a dispensing head and a dispensing linear module for driving the dispensing head to move in the X, Y, and Z directions. The dispensing head dispensing technology is existing technology and will not be described in detail here.

[0033] The flipping section includes a flipping gripper for clamping the product and flipping it 180°, a linear module for driving the flipping gripper to move back and forth between two sets of workstation slots, and a push cylinder for pushing the linear module to drive the flipping gripper to rise and fall. Therefore, the flipping gripper can be raised after clamping the product to facilitate the subsequent 180° flipping.

[0034] The positioning and material handling unit includes two sets of transition transport grippers and a transport drive module for synchronously transferring the two sets of transition transport grippers. One set of transition transport grippers is used to grab the product and transport it to the rotary positioning component. The rotary positioning component includes a rotary carrier for accommodating the product and a rotary motor for driving the rotary carrier to rotate. A positioning camera for taking pictures and positioning the product on the rotary carrier is also arranged on one side. The other set of transition transport grippers is used to synchronously grab the product on the rotary carrier and transfer it to the transition transfer component. The transition transfer component includes a transition carrier for positioning the product and a transition linear module for transferring the transition carrier to the loading end of the second transition transport component. The second transition transport component includes a second set of transition transport grippers for grabbing the product and a transport drive module for driving the second set of transition transport grippers to the tooling fixture above the loading end of the turntable.

[0035] Among them, the first transport drive module adopts the existing quick-change drive module, which can achieve fast and accurate transport effect. The two ends of the transport mounting frame in this quick-change drive module are used to symmetrically install two sets of transition transport grippers. When the transport motor drives the transport shaft to rotate 180°, it can drive the transport mounting frame, which is connected to the tail end of the transport shaft, to move horizontally and vertically in sync. The lateral guide of the transport mounting frame is limited by the lateral guide rail to ensure that the transport mounting frame does not rotate.

[0036] The second transport drive module uses a transport cylinder to facilitate the linear reciprocating motion of the second transport gripper between the loading end of the turntable and the unloading end of the transition transfer component. The transport cylinder and the second transport gripper are also driven to lift and lower via a lifting cylinder for lifting, clamping and placing products.

[0037] Thus, during the feeding process, the addition of a rotary positioning component and a transition transfer component enables synchronous photo-taking and positioning of products fed onto the turntable during the conveying process. Simultaneously, the rotary motor used to rotate the rotating carrier provides the function of rotating misaligned products back into position after photo-taking detection. Even with the added positioning function on the product feeding line, the synchronous cooperation of the transition transfer component, transition handling component one, and transition handling component one ensures that the feeding efficiency is not affected, allowing the product feeding line to achieve stable and efficient synchronous operation.

[0038] The working principle of this utility model is as follows: In this testing mechanism, a tooling fixture with two workstations is set on the turntable, and in conjunction with the surrounding height limiting part one, the central UV glue detection part one, the pin skew photography detection part one, the dispensing part one, the dispensing detection part one, the flipping part, the height limiting part two, the dispensing part two, the dispensing detection part two, and the central UV glue detection part two, the gas leakage sensor after positioning can automatically and continuously complete the double-sided dispensing and full detection process, resulting in higher production efficiency and better stability.

[0039] Furthermore, during the feeding process, the addition of rotary positioning components and transition transfer components allows for simultaneous photo-taking and positioning of products fed onto the turntable during the conveying process. Simultaneously, the rotary motor used to rotate the rotating carrier can rotate misaligned products back into position. Even with the addition of positioning functions to the product feeding line, the synchronous cooperation of the transition transfer components, transition handling components, and transition handling components ensures that the feeding efficiency is not affected, enabling the product feeding line to achieve stable and efficient synchronous operation.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
