[0023] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] like Figure 1-5 As shown, a product transfer mechanism for a pressure sensor testing device is used to install onto the pressure sensor testing device. The pressure sensor testing device includes a machine base 1 and a controller. The machine base 1 is also equipped with a loading module, a unloading module, and a testing mechanism. The product transfer mechanism includes a loading / unloading robot 2 and a product conveying module, both connected to the controller. The loading robot is connected to the loading module, the unloading module, and the product conveying module. The product conveying module is connected to the loading / unloading robot 2 and the testing mechanism. The loading / unloading robot 2 is used to pick up the products to be tested from the loading module and place them onto the product conveying module. It is also used to pick up tested products from the product conveying module and place them onto the unloading module. The product conveying module is used to transport the products to be tested to the testing mechanism and simultaneously move the tested products from the testing mechanism to the picking position of the loading / unloading robot 2.

[0026] The loading / unloading robot 2 includes a three-dimensional motion module connected to the machine base 1. A gripper cylinder 21 is mounted on the output end of the three-dimensional motion module. The three-dimensional motion module can drive the gripper cylinder 21 to move freely within three degrees of freedom to meet the loading / unloading operation requirements. The product transport module includes a transverse module 3 and a picking module 4, both connected to the machine base 1. The transverse module 3 is connected to both the three-dimensional motion module and the picking module 4. A product carrier 31 is mounted on the output end of the transverse module 3. The transverse module 3 drives the product carrier 31 to move back and forth between the picking module 4 and the loading / unloading robot 2. The picking module 4 has two picking grippers 41, which drive the picking grippers 41 to move back and forth between the transverse module 3 and the testing mechanism.

[0027] During the loading process, the host computer or a person places the product to be tested onto the loading module beforehand. The three-dimensional motion module drives the gripper cylinder 21 to move onto the loading module, and then the gripper cylinder 21 grabs the product from the loading module. The three-dimensional motion module and the gripper cylinder 21 work together to transport the product to be tested onto the product carrier 31 on the transverse module 3, thus achieving automatic loading. After loading is completed, the transverse module 3 and the picking module 4 work together to transport the product to be tested to the testing mechanism. After testing is completed, the transverse module 3 and the picking module 4 work together to transfer the tested product from the testing mechanism to the product carrier 31. After the tested product is transported to the product carrier 31, the gripper cylinder 21 is driven by the three-dimensional motion module to move to the corresponding position of the product carrier 31. Then, the gripper cylinder 21 grabs the product on the product transfer module, and the tested product is transported to the unloading module through the cooperation of the three-dimensional motion module and the gripper cylinder 21, so as to realize automatic unloading.

[0028] The product's transfer mechanism enables automatic loading, transporting, and unloading of pressure sensors without manual intervention. By replacing manual labor with machines, the automation level of the equipment is improved, enhancing the testing efficiency of pressure sensor testing equipment and meeting the requirements for high-quality testing and processing.

[0029] like Figure 2 As shown, the three-dimensional motion module includes an X-axis module 22, a Y-axis module 23, and a Z-axis module 24. The Y-axis module 23 is connected to the machine base 1. The X-axis module 22 is connected to the output end of the Y-axis module 23, and the Z-axis module 24 is connected to the output end of the X-axis module 22. The gripper cylinder 21 is connected to the output end of the Z-axis module 24. Both the X-axis module 22 and the Y-axis module 23 use existing motor lead screw modules, and their specific structures will not be described in detail here. In this embodiment, there are two Y-axis modules 23, and the two Y-axis modules 23 are arranged in parallel on the machine base 1.

[0030] like Figure 3As shown, the Z-axis module 24 includes a Z-axis mounting base 241, which is connected to the output end of the X-axis module 22. The Z-axis mounting base 241 is equipped with a Z-axis motor 242 and a Z-axis lead screw assembly 243. The output end of the Z-axis motor 242 is connected to the Z-axis lead screw assembly 243. A Z-axis slider 244 is slidably mounted on the Z-axis lead screw assembly 243. A lifting cylinder 245 is mounted on the Z-axis slider 244. A gripper cylinder 21 is connected to the output end of the lifting cylinder 245. During operation, the Z-axis motor 242 drives the Z-axis slider 244 to slide up and down on the Z-axis lead screw assembly 243, thereby driving the lifting cylinder 245 and the gripper cylinder 21 to move up and down. At the same time, in order to compensate for the lifting stroke, the lifting cylinder 245 can drive the gripper cylinder 21 to move up and down further, so that the gripper cylinder 21 can be aligned with the product carrier 31 on the loading module or the transverse module 3. After the gripper cylinder 21 is aligned with the product carrier 31 on the loading module or the transverse module 3, the gripper cylinder 21 can then pick up the product on the loading module or the tested product on the product carrier 31.

[0031] In this embodiment, there are two gripper cylinders 21 and two lifting cylinders 245, and they are arranged in a one-to-one correspondence. By providing two gripper cylinders 21 and two lifting cylinders 245, the product transfer mechanism can simultaneously complete the transfer of two products, thereby improving processing efficiency. In other embodiments, the number of gripper cylinders 21 and lifting cylinders 245 can be any other number, and this utility model does not limit this.

[0032] In actual operation, the combination of the three-dimensional motion module and the gripper cylinder 21 enables automatic loading and unloading of product transfer modules, thereby improving the automation level of the equipment.

[0033] like Figure 4 As shown, the transverse module 3 adopts the existing motor screw module, and its specific structure will not be described in detail here. The product carrier 31 is provided with four product transport slots 32; during operation, two of the product transport slots 32 are used to place the products to be tested transported by the loading and unloading robot 2, and the other two product transport slots 32 are used to place the tested products transported by the picking module 4.

[0034] like Figure 5As shown, the material handling module 4 includes a material handling fixing frame 42, on which a material handling motor 43 and a material handling screw assembly 44 are mounted. The output end of the material handling motor 43 is connected to the material handling screw assembly 44. A material handling slider 45 is slidably mounted on the material handling screw assembly 44. A material handling lifting cylinder 46 is mounted on the material handling slider 45. A gripping cylinder 47 is mounted on the output end of the material handling lifting cylinder 46. Two material handling grippers 41 are respectively mounted on the output end of the gripping cylinder 47. The gripping cylinder 47 can drive the two material handling grippers 41 to close or separate. During operation, when the transverse module 3 transports the product carrier 31 to the gripping position of the picking module 4, the picking motor 43 drives the picking screw assembly 44 to work, which in turn drives the picking slider 45 to move. The picking slider 45 drives the picking lifting cylinder 46 and the gripping cylinder 47 to move directly above the product carrier 31. Then, the picking lifting cylinder 46 drives the gripping cylinder 47 to descend, so that the two picking jaws 41 descend to the corresponding height of the product carrier 31. After that, the gripping cylinder 47 drives the two picking jaws 41 to close or separate, so that the two picking jaws 41 pick up the product from the product carrier 31 or place the product on the product carrier 31, thereby realizing the transfer process of the product between the testing mechanism and the transverse module 3.

[0035] To ensure stable product clamping by the gripper 41, clamping grooves 48 are provided on the gripper 41, and the clamping grooves 48 on the two grippers 41 are symmetrically distributed. During operation, the two grippers 41 close together, so that the two clamping grooves 48 abut against the two sides of the product respectively. The two clamping grooves 48 can stably clamp the product and prevent it from falling off during transportation.

[0036] In this embodiment, each gripper 41 is provided with two gripping slots 48, so that the gripping cylinder 47 can grip two products simultaneously, improving processing efficiency. In other embodiments, the number of gripping slots 48 can be any other number, and this utility model does not limit this.

[0037] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
