Description

Technical Field

[0001] This utility model relates to the field of automated production technology of sealing oil seals, and in particular to a clamping and detection device for an oil seal injection machine. Background Technology

[0002] Currently, the application scenarios for sealing components and oil seals are constantly expanding, and correspondingly, the demand for production capacity and performance requirements are also continuously increasing. In the field of high-end oil seal manufacturing, injection molding technology has been widely adopted. While ensuring product quality, it can also be combined with automated loading and unloading systems to further improve production efficiency.

[0003] However, most injection molding machines are not yet fully automated, especially in the part removal process, where significant bottlenecks remain, mainly in the following two aspects: First, the testing institutions have poor versatility and cannot adapt to products of different heights. Every time a product is changed, the sensors need to be readjusted, which affects the production cycle and flexibility. Secondly, during injection gripping, the equipment is often in a high-temperature state and is accompanied by spraying media such as spraying liquid. Under such harsh working conditions for a long time, the sensor is easily affected by high heat and spraying media, which leads to a decrease in detection stability and even causes misjudgment, directly affecting the reliability and continuity of the automation system. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a gripping and detection device for an oil seal injection machine that can adapt to products of different heights and achieve rapid production changeover without adjusting the sensor, thereby improving production flexibility and efficiency. The use of a fixing plate physically isolates the sensor from the high heat and spraying liquid at the gripping end, fundamentally ensuring the service life of the sensor and guaranteeing the continuity and stability of long-term production.

[0005] To solve the above-mentioned technical problems, the present invention provides a gripping and detection device for an oil seal injection machine, comprising a fixed plate, a gripper assembly, a detection triggering assembly, and a sensor assembly. The gripper assembly is installed below the fixed plate and includes a gripper cylinder, a gripper connecting plate connected to the gripper cylinder, and product grippers disposed on the gripper connecting plate for gripping products. The detection triggering assembly includes a pressure plate, a guide rod, a guide sleeve, a detection mounting plate, and a detection block. The guide sleeve is installed above the fixed plate, and the guide rod passes through the guide sleeve. The upper end of the guide rod is equipped with the detection mounting plate, and the lower end is equipped with the pressure plate. The detection block is mounted on the upper surface of the detection mounting plate. The sensor assembly includes a slotted photoelectric mounting plate mounted on the fixed plate and a slotted photoelectric sensor mounted on the slotted photoelectric mounting plate. The position of the slotted photoelectric sensor corresponds to the movement path of the detection block.

[0006] In a preferred embodiment of the present invention, the gripper cylinder is installed in the mounting hole at the lower end of the fixed plate, and the gripper connecting plate is connected to the mounting hole of the gripper cylinder.

[0007] In a preferred embodiment of this utility model, there are two product grippers, symmetrically arranged on both sides of the gripper connecting plate, which are driven by gripper cylinders to achieve synchronous opening and closing. The gripping surface of the product grippers is provided with arc-shaped grooves or anti-slip textures that are adapted to the shape of the product.

[0008] In a preferred embodiment of this utility model, the guide rod and the guide sleeve are clearance-fitted to form a sliding pair.

[0009] In a preferred embodiment of this utility model, two guide rods and two guide sleeves are provided, symmetrically arranged on both sides of the gripper cylinder.

[0010] In a preferred embodiment of the present invention, the lower end face of the pressure plate is provided with an elastic buffer layer.

[0011] In a preferred embodiment of this utility model, the slotted photoelectric mounting plate is a T-shaped plate, with its bottom end face mounted on the top surface of the fixing plate and the slotted photoelectric plate mounted on its side end face.

[0012] In a preferred embodiment of the present invention, the slotted photoelectric device has a U-shaped detection slot, the opening of which faces the moving path of the detection block.

[0013] The beneficial effects of this utility model are: by detecting the adaptive displacement sensing of the trigger component, rapid identification and grasping of products of different heights are achieved, and there is no need to adjust the position of the sensor during product changeover; by fixing the plate, the sensor component is effectively isolated from the harsh environment such as high temperature and spraying liquid at the grasping end in physical space, which fundamentally avoids sensor failure due to overheating or contamination, ensures the service life of the sensor, and ensures the continuity and stability of long-term production.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0016] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] This utility model relates to a clamping and detection device for an oil seal injection machine, belonging to the field of automated production of sealing oil seals.

[0018] Please see Figure 1 The oil seal injection machine clamping and detection device includes a fixing plate 7, a gripper assembly, a detection trigger assembly, and a sensor assembly.

[0019] Specifically, the first is the gripper assembly, which is installed below the fixed plate 7 and is used to grip the oil seal of the sealing component. The gripper assembly includes a gripper cylinder 5, a gripper connecting plate 4 connected to the gripper cylinder 5, and a product gripper 3 set on the gripper connecting plate 4.

[0020] Furthermore, the gripper cylinder 5 is installed in the mounting hole at the lower end of the fixing plate 7 to achieve a stable connection, and the gripper connecting plate 4 is connected to the mounting hole of the gripper cylinder 5.

[0021] In this embodiment, there are two product grippers 3, which are symmetrically arranged on both sides of the gripper connecting plate 4 and are driven by the gripper cylinder 5 to achieve synchronous opening and closing movements.

[0022] To prevent the product from moving or being damaged during the clamping process, the clamping surface of the product gripper 3 may be provided with an arc-shaped groove or anti-slip texture that matches the shape of the product to ensure stable clamping of the product.

[0023] Secondly, there is a detection triggering component, which is used to trigger a detection signal when the product is clamped. It includes a pressure plate 2, a guide rod 6, a guide sleeve 8, a detection mounting plate 9, and a detection block 11. The guide sleeve 8 is installed above the fixed plate 7, and the guide rod 6 passes through the guide sleeve. The guide rod 6 and the guide sleeve 8 are clearance fit to form a sliding pair, ensuring that the guide rod 6 can slide smoothly along the guide sleeve.

[0024] To ensure the stability of the movement, two guide rods 6 and two guide sleeves 7 are provided, symmetrically arranged on both sides of the gripper cylinder 5.

[0025] Furthermore, a detection mounting plate 9 is installed on the upper end of the guide rod 6, and a pressure plate 2 is installed on the lower end. The detection block 11 is installed on the upper surface of the detection mounting plate 9. At the same time, an elastic buffer layer is provided on the lower surface of the pressure plate 2 to avoid damage to the product during the clamping process.

[0026] Furthermore, there is a sensor assembly used to detect the action signal of the aforementioned detection trigger assembly, including a slotted photoelectric mounting plate 10 and a slotted photoelectric sensor 12. The slotted photoelectric mounting plate 10 is mounted on the fixed plate 7, and the slotted photoelectric sensor 12 is mounted on the slotted photoelectric mounting plate 10. The position of the slotted photoelectric sensor 12 corresponds to the movement path of the detection block 11.

[0027] Specifically, the slotted photoelectric mounting plate 10 is a T-shaped plate, with its bottom end face mounted on the top surface of the fixing plate 7, and its side end face used to mount the slotted photoelectric 12.

[0028] Among them, the slotted photoelectric device 12 has a U-shaped detection slot, the opening of which faces the moving path of the detection block 11, so as to reliably detect the position change of the detection block 11 when it moves with the guide rod 6, and ensure that the passing state of the detection block 11 can be accurately and reliably detected.

[0029] By employing a detection method that adaptively triggers slotted photoelectric sensors based on the product height, rapid switching and gripping of products at different heights is achieved. Since the detection relies on the relative displacement generated after the pressure plate contacts the product, rather than the product's absolute height, no sensor position adjustment is required when switching between different product specifications, significantly improving production flexibility and efficiency.

[0030] In operation, the fixed plate serves as a load-bearing and protective structure, effectively separating the gripper cylinder, detection triggering component, and the sensor assembly above. This plate-type isolation design keeps the slotted photoelectric sensor away from the high heat and harsh environment of the injection molding machine's gripping area, fundamentally preventing performance degradation and misjudgments caused by high temperatures or media contamination, ensuring its service life, and further guaranteeing the long-term stability and reliability of the entire production line.

[0031] The working principle of this utility model oil seal injection machine clamping and detection device is as follows: In the initial state, the pressure plate 2, guide rod 6 and detection mounting plate 9 are at the lower limit position under their own weight, and at this time the detection block 11 is outside the sensing area of ​​the slotted photoelectric sensor 12; When the device descends to grab product 1, the pressure plate 2 first contacts the surface of product 1. As it continues to descend, product 1 generates a reaction force on the pressure plate 2, which pushes the guide rod 6 to drive the detection mounting plate 9 and the detection block 11 to move upward along the guide sleeve 8. When the detection block 11 rises to enter the U-shaped detection groove of the slotted photoelectric sensor 12, the slotted photoelectric sensor 12 is triggered and outputs a signal. This signal is transmitted to the control system, which immediately controls the gripper cylinder 5 to operate, driving the product gripper 3 to close and complete the gripping operation.

[0032] This invention achieves precise judgment of the gripping position by organically combining mechanical contact and photoelectric detection, effectively improving the reliability and automation of oil seal gripping.

[0033] The beneficial effects of this utility model oil seal injection machine clamping and detection device are: It can adapt to products of different heights and achieve rapid production changeover without adjusting sensors, thus improving production flexibility and efficiency; The mounting plate physically isolates the sensor from the high heat and spraying liquid at the gripping end, fundamentally ensuring the sensor's service life and guaranteeing the continuity and stability of long-term production.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
