Description

Technical Field

[0001] The utility model relates to the technical field of injection molded product detection, in particular to an insert detection device. Background Art

[0002] Injection molds are tools used to make molded plastic products. The basic principle is to inject molten plastic material into the mold, and then solidify the plastic material in the mold through pressurization and cooling to form the desired shape of the product. With the continuous advancement and innovation of science and technology, the injection mold industry is also developing continuously. At present, injection mold processing technology has been widely used in many fields, such as the automotive industry, electronic and electrical industry, home appliance industry, medical equipment, daily necessities, packaging industry, construction industry and toy industry.

[0003] The preparations made by injection mold processing usually contain inserts, which are usually wrapped into the injection molded products during the manufacturing process to form non-detachable connectors. Adding inserts to injection molded products can not only install them, but also increase the functions of injection molded products, such as increasing the local strength, hardness, rigidity and wear resistance of injection molded products. Pressing metal inserts such as brass and silver into injection molded products can make the products meet the requirements of magnetic conductivity and electrical conductivity.

[0004] After the insert is installed, it needs to be inspected to avoid missing parts. The traditional inspection method is manual inspection, that is, visual inspection, touch inspection, etc. to determine whether the insert is missing. However, manual inspection has the disadvantages of strong subjectivity, low efficiency and easy fatigue, resulting in inaccurate inspection. Utility Model Content

[0023] In order to make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Apparently, the described embodiments are partial embodiments of the present utility model rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figures 1 to 4 shown, an insert detection device includes a mounting mechanism 1, and a product clamping device 2, a detection sensor 3, a relay 4 and a robotic arm joint 5 disposed on the mounting mechanism 1. A signal receiving terminal 6 is further provided on the robotic arm joint 5; the product clamping device 2 is used for clamping a product to be detected 7, and the detection sensor 3 is used for detecting an insert on the product to be detected 7; the detection sensor 3 is connected to the relay 4 through a first signal transmission line 8, and the relay 4 is connected to the signal receiving terminal 6 through a second signal transmission line 9.

[0025] The insert detection device of the present utility model is mainly used to detect whether an insert in an injection mold product is missed. The mounting mechanism 1 is mainly used for mounting various components, such as the product clamping device 2, the detection sensor 3, the relay 4 and the robotic arm joint 5. The robotic arm joint 5 is used for connecting with an external robotic arm, and the external robotic arm drives the entire mounting mechanism 1 to move. Among them, the robotic arm joint 5 is connected to the external robotic arm through a pneumatic interface 11. The above connection manner is a common manner in the prior art and will not be elaborated here.

[0026] When detecting the product to be detected 7, first, the product to be detected 7 is clamped by the product clamping device 2. The product clamping device 2 is a common robotic gripper in the prior art. Each time the product to be detected 7 is clamped at the same position, it can ensure that the insert on the product to be detected 7 is at the same position each time, and further enable the insert on the product to be detected 7 to cooperate with the detection sensor 3.

[0027] The detection sensor 3 is mainly used to sense whether an insert exists in the product to be detected 7. The type of the detection sensor 3 can be selected according to actual situations, such as a metal sensor, a pressure sensor and a ranging sensor.

[0028] In an embodiment of the present utility model, the insert on the product 7 to be detected is metal, and the detection sensor 3 is a high-precision metal sensor. The high-precision metal sensor in the present utility model is a common high-precision metal sensor in the prior art, which mainly includes an electromagnetic induction high-frequency oscillation type, a magnet magnetic force type, and a capacitance change capacitance type. The specific type can be selected according to actual needs.

[0029] In other embodiments of the present utility model, the detection sensor 3 is a pressure sensor or a ranging sensor. The pressure sensor can sense the pressure signal of the insert and convert the pressure signal into an available output electrical signal. Since the pressure signal detected by the pressure sensor when the insert is missing is different from that when it is normally installed, the pressure sensor can be used to detect whether the insert is missing. The ranging sensor can be an ultrasonic ranging sensor, a laser ranging sensor, or an infrared ranging sensor. No matter which type it is, its principle is relatively similar, mainly based on the emission, reflection, and reception of physical signals, and calculates the target distance by measuring parameters such as the time difference or phase difference of signal transmission. During actual detection, since the distance signal of the ranging sensor when the insert is missing is different from that when it is normally installed, the ranging sensor can be used to detect whether the insert is missing.

[0030] The relay 4 in the present utility model is a common electrical control device in the prior art. When the change in its input quantity reaches the specified requirement, it causes a predetermined step change in the controlled quantity in the electrical output circuit. In the present utility model, the detection sensor 3 and the relay 4 are connected by a first signal transmission line 8, and the relay 4 and the signal receiving terminal 6 are connected by a second signal transmission line 9. Among them, the first signal transmission line 8 is a detection signal transmission cable, and the second signal transmission line 9 is a summary signal transmission cable. During operation, the detection sensor 3 transmits the collected signal to the relay 4 through the first signal line. When the relay 4 displays the lighting or extinguishing state of the indicator light according to the signal transmitted by the detection sensor 3, then the relay 4 integrates all the collected point signals into one signal and transmits it to the signal receiving terminal 6 on the robotic arm joint 5 through the second signal transmission line 9. The signal receiving terminal 6 transmits the signal to an external control device. The external control device can identify whether there is an insert missing on the product 7 to be detected according to the received signal. If there is a missing insert, it is a non-conforming product. At this time, the external control device controls the robotic arm to move to the non-conforming product placement location and places the detected product at the non-conforming product placement location; if there is no missing insert, it is a conforming product. At this time, the external control device controls the robotic arm to move to the conforming product placement location and places the detected product at the conforming product placement location.

[0031] The principle of the relay 4 status display in the present utility model is as follows:

[0032] In actual use, the relay 4 can be regarded as a switch group composed of multiple switches. Each detection sensor 3 is individually connected to a switch point. The indicator light at this point is turned on and off according to the detection signal of the detection sensor 3. When the detection sensor 3 does not detect the insert, the indicator light is turned off. When the insert is detected, the indicator light is turned on. During operation, the missing installation situation of the inserts detected at each detection point can be judged by the states of the indicator lights at multiple switch points, which is convenient for daily inspection and maintenance by relevant staff.

[0033] The signal integration principle of the relay 4 in this utility model is briefly described as follows:

[0034] In actual use, the relay 4 can be regarded as a switch group composed of multiple switches. Each detection sensor 3 is individually connected to a switch point. The final closing or opening of the relay 4 is determined by the state detected by each detection sensor 3. Specifically, the multiple switch points corresponding to each detection sensor 3 are connected in series and then connected to the output point.

[0035] In the above integration principle, when a single switch point is not connected, the output point signal is 0. The signal receiving terminal 6 transmits the signal to the external control device. The external control device identifies that the insert is missing from the product 7 to be detected according to the received signal, determines it as a non-conforming product, and controls the robotic arm to move to the placement location for non-conforming products and place the detected product at the placement location for non-conforming products.

[0036] In the above integration principle, when all single switch points are connected, the output point signal is 1. The signal receiving terminal 6 transmits the signal to the external control device. The external control device identifies that there is no missing insert in the product 7 to be detected according to the received signal, determines it as a conforming product, and controls the robotic arm to move to the placement location for conforming products and place the detected product at the placement location for conforming products.

[0037] In this utility model, the number of product clamping devices 2 is more than one. Each product clamping device 2 corresponds to a detection sensor 3, and the position and number of the detection sensors 3 correspond to the position and number of the inserts on the product 7 to be detected. When the number of product clamping devices 2 is two or more, a corresponding relay 4 and a corresponding set of detection sensors 3 need to be set separately. In a preferred solution of this utility model, the number of product clamping devices 2 is two. During operation, only one product clamping device 2 and the matching detection sensor 3 can be used, and the other can be used as a backup; or two product clamping devices 2 and the matching detection sensors 3 can be used simultaneously to detect two products 7 to be detected at the same time to improve work efficiency.

[0038] In the present utility model, the detection sensor 3 is fixed to the mounting mechanism 1 through the mounting base 10. The mounting base 10 can ensure the stable mounting of the detection sensor 3, thereby guaranteeing the accuracy and reliability of the measurement. At the same time, it is also more convenient to operate when maintenance or replacement is required.

[0039] In the present utility model, the article clamping device 2 is a pneumatic gripper. The pneumatic gripper is a common structure in the prior art, and its principle is mainly based on the design of pneumatic control and mechanical structure, and realizes the clamping and releasing of objects through the telescopic movement of the cylinder. The structure of the pneumatic gripper in the present utility model can be adjusted according to the structure of the article to be detected 7, and those skilled in the art can achieve it conventionally on the basis of knowing the principle of the pneumatic gripper.

[0040] As Figures 2 to 3 shown, in the present utility model, the mounting mechanism 1 includes a first mounting plate 101, a second mounting plate 102, and a connecting column 103 for connecting the first mounting plate 101 and the second mounting plate 102; the article clamping device 2 and the detection sensor 3 are both fixed to the first mounting plate 101, and the relay 4 and the robotic arm joint 5 are both fixed to the second mounting plate 102.

[0041] Dividing the mounting mechanism 1 into two mounting plates facilitates the centralized mounting of components with different functions to prevent the mutual influence of each component. Specifically, the article clamping device 2 and the detection sensor 3 are both components required for detection and both need to contact the article to be detected 7, so they are mounted on the first mounting plate 101; while the relay 4 and the robotic arm joint 5 do not need to contact the article to be detected 7 during operation, and they are mounted on the second mounting plate 102 to prevent the relay 4 and the robotic arm joint 5 from being touched or scratched after the article to be detected 7 is clamped. The above structure has good practicability and guarantees the safety and stability of the device during operation.

[0042] The above-described specific embodiments have further elaborated on the purpose, technical solution, and beneficial effects of the present utility model. It should be understood that the above is only the specific implementation method of the present utility model and is not used to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the gist of the present utility model should be included within the protection scope of the present utility model.
