Description

Technical Field

[0001] This utility model relates to the field of sensor production and testing equipment, and in particular to an automatic loading and unloading device for sensor helium detection. Background Technology

[0002] With the advancement of social technology, automated equipment is being used more and more widely in various industries, which has also driven the rapid development of various sensors. After ESC sensors are manufactured and assembled, they are generally tested in sensor helium detection equipment to ensure quality. To ensure accuracy and airtightness during testing at the sensor helium detection station, and to control costs, a vertical limiting structure is used. This vertical limiting structure obstructs the loading and unloading of the robotic arm, allowing products to be transferred only from the front. This restricts the loading end of the loading and unloading equipment used in conjunction with the sensor helium detection equipment, limiting the number of products that can be picked up at a time. This results in low loading and unloading efficiency at multiple testing stations of the sensor helium detection equipment. Increasing the loading and unloading speed of the robotic arm would affect the stability of the detection process. Utility Model Content

[0003] This utility model provides an automatic loading and unloading device for sensor helium detection, which solves the technical problem that the loading and unloading efficiency of the loading and unloading device used in conjunction with the sensor helium detection device is low, and that increasing the loading and unloading speed of the robot arm will affect the stability of the detection.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an automatic loading and unloading device for sensor helium detection, including a device housing, a fixed base plate disposed inside the device housing, and at least one set of loading and unloading components disposed on the fixed base plate. The loading and unloading components include two product transfer mechanisms for loading and unloading respectively, a defective product storage mechanism for temporarily storing defective products, and a product transfer mechanism for transferring products between the sensor helium detection device, the product transfer mechanisms, and the defective product storage mechanism. The product transfer mechanism includes a multi-axis robotic arm, a transfer plate driven by the multi-axis robotic arm to move and rotate in the vertical and horizontal directions, and multiple product pick-and-place heads symmetrically disposed at both ends of the transfer plate. A barcode scanning mechanism for scanning the products on the product pick-and-place heads is disposed on one side of the product transfer mechanism. The device offers high loading and unloading efficiency and good stability.

[0005] Furthermore, the product transfer mechanism includes two support plates vertically arranged side-by-side on a fixed base plate, two first horizontal slide rail assemblies horizontally arranged correspondingly on the inner sides of the two support plates, a first sliding plate horizontally slidable on the two first horizontal slide rail assemblies, a first horizontal drive mechanism located on the outer side of the support plates and connected to drive the first sliding plate horizontally, two second horizontal slide rail assemblies horizontally arranged correspondingly on the inner sides of the two support plates and located below the two first horizontal slide rail assemblies, a second sliding plate horizontally slidable on the two second horizontal slide rail assemblies, a second horizontal drive mechanism located on the inner side of the support plates and connected to drive the second sliding plate horizontally, and multiple product storage trays for batch storage of products. Both the first and second sliding plates are provided with limiting structures for positioning the product storage trays. Structural fixing plates are provided at both ends of the two support plates, and positioning sensing mechanisms for sensing and positioning the product storage trays are provided on the inner sides of the structural fixing plates. This simple structure enables product inspection and loading / unloading.

[0006] Furthermore, the defective product temporary storage mechanism includes a fixed frame, a temporary storage plate limiting structure mounted on the fixed support, and a removable defective temporary storage plate limited by the temporary storage plate limiting structure. The defective temporary storage plate is provided with product placement slots evenly distributed for batch placement of defective products. The fixed frame is equipped with a temporary storage plate detection mechanism to detect the presence and position of defective temporary storage plates. Direct replacement of defective temporary storage plates improves efficiency, and the temporary storage plate detection mechanism ensures the safety of personnel and equipment during the production process.

[0007] Furthermore, two product pick-and-place heads are arranged side-by-side on the lower surfaces of both ends of the transfer plate. Each product pick-and-place head includes a vertical drive mechanism fixedly mounted on the lower surface of the transfer plate, an automatic gripper mounted on the vertical drive mechanism and driven by the vertical drive mechanism to move vertically, and a contoured claw finger mounted on the automatic gripper and driven by the automatic gripper to hold and place the product. Each product pick-and-place head operates independently, providing good applicability.

[0008] Furthermore, the loading and unloading components are arranged in two sets correspondingly on both sides of the fixed base plate, and a barcode scanning bracket is provided in the middle of the fixed base plate. Two barcode scanning mechanisms are adjustablely mounted on the barcode scanning bracket and are used to scan products in operation by the two sets of loading and unloading components. In this specific embodiment, the barcode scanning mechanisms are adjustablely fixed to the barcode scanning bracket, which is composed of vertical and horizontal sliding rods and clamping blocks, using a clamping structure and bolts. The structure is simple and practical.

[0009] Furthermore, the upper part of the device housing extends towards the sensor helium detection device from the side closest to it, reducing interference between the two devices.

[0010] Furthermore, the device housing is equipped with multiple guide and limiting docking structures for docking and limiting with the sensor helium detection equipment. In this specific embodiment, the guide and limiting docking structure consists of a first docking block and a second docking block respectively installed on the two types of equipment.

In practical implementation, the two devices can be directly positioned and docked using the guide and limiting docking structures, making the operation convenient and simple.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1An automatic loading and unloading device for helium detector sensors is shown, comprising a housing 100, a fixed base plate 101 disposed within the housing 100, and at least one loading and unloading assembly disposed on the fixed base plate 101. The loading and unloading assembly includes two product transfer mechanisms 200 for loading and unloading respectively, a defective product storage mechanism 300 for temporarily storing defective products, and a product transfer mechanism for transferring products between the sensor helium detector, the product transfer mechanisms 200, and the defective product storage mechanism 300. The product transfer mechanism includes a multi-axis robotic arm 410, a transfer plate 420 driven by the multi-axis robotic arm 410 to move and rotate in the vertical and horizontal directions, and multiple product pick-and-place heads 430 symmetrically disposed at both ends of the transfer plate 420. A barcode scanning mechanism 500 is disposed on one side of the product transfer mechanism for scanning the products on the product pick-and-place heads 430.

[0018] In this specific embodiment, the multi-axis robotic arm 410 is a commercially available four-axis robotic arm. In practice, the product transfer mechanism transfers the products fed by the product transfer mechanism 200 to the sensor helium detector for testing, and then lowers the tested products to the unloading transfer mechanism 200 for unloading. During this process, the scanning mechanism 500 scans the products before and after testing to determine the corresponding information of the tested products and the corresponding test results, which are then input into the system. The width of the transfer plate 420 is within the allowable size range of the sensor helium detector's testing station. The number of product pick-and-place heads 430 at the end of the transfer plate 420 is the same as the number of products placed at the sensor helium detector's testing station. This means that the transfer plate 420 can pick up products placed at two testing stations of the sensor helium detector at once.

[0019] In practice, initially, when the product transfer mechanism picks up materials, the multi-axis robotic arm 410 drives the product pick-up and placement heads 430 at both ends of the transfer plate 420 to pick up products in the product transfer mechanism 200 used for feeding. The multi-axis robotic arm 410 drives the transfer plate 420 to place the product picked up by the product pick-up and placement head 430 at one end onto a detection station of the sensor helium detection equipment, and then exits. After the drive transfer plate 420 rotates horizontally by 180 degrees, the drive transfer plate 420 places the product picked up by the product pick-up and placement head 430 at the other end onto another detection station of the sensor helium detection equipment. During this process, the barcode scanning mechanism 500 scans the products picked up and fed into the sensor helium detection equipment.

[0020] Then, the multi-axis robotic arm 410 drives the product pick-and-place head 430 at one end of the transfer plate 420 to pick up the product in the product transfer mechanism 200 used for loading. After the product testing at one detection station of the sensor helium detector is completed, the end of the multi-axis robotic arm 410 that did not pick up the product enters the detection station of the sensor helium detector to pick up the tested product. The multi-axis robotic arm 410 then drives the transfer plate 420 to exit the detection station of the sensor helium detector and then rotates horizontally 180 degrees to place the other end of the product pick-and-place head 430 in the product transfer mechanism 200 used for loading. Untested products picked up in mechanism 200 are placed on the testing station of the sensor helium detection equipment. The multi-axis robotic arm 410 drives the product pick-up and place head 430 at one end of the transfer plate 420 to pick up the tested products and transfer them to the unloading product transfer mechanism 200. During this process, the barcode scanning mechanism 500 scans the products picked up and loaded onto the sensor helium detection equipment and the tested products picked up on the sensor helium detection equipment. This operation is repeated to cycle the loading and unloading of products on the testing station of the sensor helium detection equipment. During the unloading process, defective products are scanned and unloaded into the defective product temporary storage mechanism 300.

[0021] It has high material loading and unloading efficiency and good stability.

[0022] Based on the above, such as Figure 1 and Figure 2 As shown, the product transfer mechanism 200 includes two support plates 211 vertically arranged side by side on the fixed base plate 101, two first horizontal slide rail assemblies 212 horizontally arranged side by side corresponding to the inner sides of the two support plates 211, a first slide plate 213 horizontally slidably arranged on the two first horizontal slide rail assemblies 212, a first horizontal drive mechanism 214 arranged outside the support plates 211 and connected to drive the first slide plate 213 to slide horizontally, and two second horizontal slide rail assemblies horizontally arranged side by side corresponding to the inner sides of the two support plates 211 and located below the two first horizontal slide rail assemblies 212. 215. A second sliding plate 216 is horizontally slidably mounted on two second horizontal slide rail assemblies 215. A second horizontal drive mechanism is mounted inside the support frame 211 and connects to drive the second sliding plate 216 to slide horizontally. A plurality of product storage trays 217 for batch storage of products are provided. The first sliding plate 213 and the second sliding plate 216 are both provided with limiting structures for limiting the product storage trays 217. Both ends of the two support frames 211 are provided with structural fixing plates 220. The inner side of the structural fixing plates 220 is provided with positioning sensing mechanisms 230 for sensing and positioning the product storage trays 217.

[0023] In this specific embodiment, the first horizontal drive mechanism 214 and the second horizontal drive mechanism are cylinder assemblies with controllable stroke. In further implementations, they can also be linear cylinders or other controllable linear drive mechanisms. The positioning sensing mechanism 230 is a laser sensor. In a specific implementation, during feeding, the product storage tray 217 filled with products is placed on the limiting mechanism on the first slide plate 213 and the second slide plate 216. Under the drive of the first horizontal drive mechanism 214, the first slide plate 213 is transferred along the first horizontal slide rail assembly 212 to the picking range of the product transfer mechanism. When the product storage tray 217 is filled with products on the first slide plate 213... After the products in tray 217 are removed by the product transfer mechanism, the second slide plate 216, driven by the second horizontal drive mechanism 317, moves along the second horizontal slide rail assembly 215 to the product transfer mechanism's picking range. The first slide plate 213, driven by the first horizontal drive mechanism 214, moves along the first horizontal slide rail assembly 212 to outside the product transfer mechanism's picking range, removing the empty product storage tray 217 and replacing it with a product storage tray 217 loaded with products. When the products in tray 217 on the second slide plate 216 are removed by the product transfer mechanism, the first slide plate 213, driven by the first horizontal drive mechanism 317, moves along the second horizontal slide rail assembly 215 to the product transfer mechanism's picking range. Driven by mechanism 214, the first horizontal slide rail assembly 212 moves the second slide plate 216 to the material handling range of the product transfer mechanism. Driven by the second horizontal drive mechanism 317, the second slide plate 216 moves the second horizontal slide rail assembly 215 to the outside of the material handling range of the product transfer mechanism to remove the empty product storage tray 217 and replace it with a product storage tray 217 loaded with products. This cycle is repeated to ensure that there are always untested products available for the product transfer mechanism to load within its transfer range. During unloading, the empty product storage tray 217 is placed on the limiting mechanism on the first slide plate 213 and the second slide plate 216. The first slide plate 213... Driven by the first horizontal drive mechanism 214, the product storage tray 217 moves along the first horizontal slide rail assembly 212 to the product transfer mechanism's feeding range. When the product storage tray 217 on the first slide plate 213 is full of products, the second slide plate 216 moves along the second horizontal slide rail assembly 215 under the drive of the second horizontal drive mechanism 317 to the product transfer mechanism's feeding range. The first slide plate 213 moves along the first horizontal slide rail assembly 212 under the drive of the first horizontal drive mechanism 214 to outside the product transfer mechanism's feeding range. The full product storage tray 217 is removed, and the empty product storage tray 217 is replaced.When the product storage tray 217 on the second slide plate 216 is full of products, the first slide plate 213, driven by the first horizontal drive mechanism 214, moves along the first horizontal slide rail assembly 212 to the unloading range of the product transfer mechanism. The second slide plate 216, driven by the second horizontal drive mechanism 317, moves along the second horizontal slide rail assembly 215 to outside the unloading range of the product transfer mechanism. The full product storage tray 217 is removed, and the empty product storage tray 217 is replaced. This cycle is repeated to ensure that there is always a product storage tray 217 available for the product transfer mechanism to place and inspected products within its transfer range. This simple structure enables the loading and unloading of products for inspection.

[0024] Based on the above, such as Figure 1 As shown, the defective product temporary storage mechanism 300 includes a fixed frame, a temporary storage plate limiting structure mounted on the fixed support, and a removable defective temporary storage plate limited by the temporary storage plate limiting structure. The defective temporary storage plate is provided with product placement slots evenly distributed for batch placement of defective products. The fixed frame is provided with a temporary storage plate detection mechanism for detecting the presence and position of the defective temporary storage plate. In this specific implementation, the temporary storage plate detection mechanism is a laser sensor. In practice, when the defective temporary storage plate is full, the equipment will determine that it is full based on the quantity and alarm to remind the operator. The operator will then replace the entire defective temporary storage plate with an empty one. During the replacement process, if the temporary storage plate detection mechanism detects that the defective temporary storage plate is not in the preset position, the product transfer mechanism will pause the transfer of defective products to the defective temporary storage plate, directly replacing the defective temporary storage plate, which improves efficiency. The temporary storage plate detection mechanism ensures the safety of personnel and equipment during the production process.

[0025] Based on the above, such as Figure 1 and Figure 3 As shown, two product pick-and-place heads 430 are arranged side-by-side on the lower surfaces of both ends of the transfer plate 420. Each product pick-and-place head 430 includes a vertical drive mechanism 431 fixedly mounted on the lower surface of the transfer plate 420, an automatic gripper 432 mounted on the vertical drive mechanism 431 and driven by the vertical drive mechanism 431 to move vertically, and a contoured gripper finger 433 mounted on the automatic gripper 432 and driven by the automatic gripper 432 to grip and place products. In this specific embodiment, the vertical drive mechanism 431 is a sliding cylinder, and the automatic gripper 432 is a pneumatic gripper. In actual implementation, the vertical drive mechanism 431 can also be a rodless cylinder with controllable stroke or a linear drive mechanism with controllable stroke, such as a linear motor. Each product pick-and-place head 430 operates independently, offering good applicability.

[0026] Based on the above, such as Figure 1As shown, the loading and unloading components are arranged in two sets on both sides of the fixed base plate 101. A barcode scanning bracket is provided in the middle of the fixed base plate 101. Two barcode scanning mechanisms 500 are arranged on the barcode scanning bracket with adjustable positions, respectively used to scan the products of the two loading and unloading components in operation. In this specific embodiment, the barcode scanning mechanism 500 is adjustablely fixed to the barcode scanning bracket composed of vertical and horizontal sliding rods and clamping blocks by means of a clamping structure and bolts. The structure is simple and practical.

[0027] Based on the above, such as Figure 1 and Figure 4 As shown, the upper part of the device housing 100 extends towards the sensor helium detection device from the side closest to it. This reduces interference between the two devices.

[0028] Based on the above, such as Figure 1 and Figure 4 As shown, the device housing 100 is provided with multiple guide and limiting docking structures 600 for docking and limiting with the sensor helium detection equipment. In this specific embodiment, the guide and limiting docking structure 600 consists of a first docking block or a second docking block respectively installed on the two types of equipment. Each of the first and second docking blocks has a matching guide docking angle and a guide docking groove at one end. In practical implementation, the two devices can be directly positioned and docked using the guide and limiting docking structure 600, making the operation convenient and simple.

It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
