Description
Technical Field
[0001] The utility model relates to the technical field of welding tooling, in particular to a welding tooling with a light-sensing error-proofing mechanism. Background Art
[0002] Welding can make plastic parts connect stably and effectively. When welding plastic parts, the connection parts of the two plastic parts to be welded need to be positioned to ensure the stability of welding. The existing plastic parts welding process mostly relies on manual positioning, especially when multiple parts are assembled and welded, it is easy to cause missing parts. In addition, there is a lack of detection devices before welding, and the product defect rate is high. Now there is an urgent need for a detection mechanism to detect whether the welded parts are missing before welding. Welding tooling is a set of flexible welding fixing, pressing and positioning fixtures, which are mainly used for welding various weldable materials, including large, medium and small materials.
[0003] Common welding jigs are usually composed of structures such as fixtures and positioning devices, clamping mechanisms, transmission and control systems, and basic platforms and support structures. First, correctly assemble the various parts of the jig together, place the workpiece to be welded on the jig, and use the positioning device and clamping mechanism of the jig to accurately fix the workpiece. This is a common welding jig structure and usage method. Traditional welding jigs cannot accurately detect whether rubber pads are installed at the corresponding positions before welding, and failure to add rubber pads will lead to defective products during welding. Some welding jigs detect whether rubber pads exist by adding probes. However, in this way, due to the accuracy, fragility, operation complexity and detection speed of the probe, the probe added to the welding jig is not convenient to use. At the same time, frequent replacement increases the cost of use, and it is impossible to accurately detect whether the rubber pad is missing, resulting in defective products. For this reason, a welding jig with a light-sensing error-proofing mechanism is proposed. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the deficiencies in the prior art, the utility model provides a welding tool with a light-sensing error-proofing mechanism to solve the above-mentioned technical problem of being unable to accurately detect whether there is a phenomenon of missing rubber pads.
[0006] (II) Technical solution
[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a welding tool with a light-sensing error-proofing mechanism, comprising:
[0008] A welding head, and a positioning seat arranged just below the bottom of the welding head, wherein a positioning groove is provided at the top center of the positioning seat, and fixing screws are installed at the front and rear ends of both sides of the positioning seat;
[0009] The welding shell is arranged at the bottom of the positioning groove, and a rubber pad is added to the top of the welding shell, and a welding iron sheet is connected to the top of the rubber pad;
[0010] The photosensitive head is set at the center of the inner cavity of the positioning seat, and a photosensitive sensor is installed at the center of the back of the positioning seat and connected to the photosensitive head. The operator first places the rubber pad in the middle groove of the welding shell, and then places the welding iron sheet on the rubber pad. The small columns on the welding shell correspond to the small holes of the welding iron sheet. Then the welding shell, rubber pad and welding iron sheet are put into the positioning groove of the positioning seat together. The positioning seat is fixed to the welding workbench with fixing screws; then press the welding button. If the photosensitive head senses that the environment is dark at this time, after processing by the photosensitive sensor, it proves that the rubber pad is not missing at this time. The welding machine drives the welding head downward. If the photosensitive head senses that the environment is bright at this time, it proves that the rubber pad is missing at this time. After the photosensitive sensor, the welding The machine triggers the alarm, the operator takes out the welded part to check and reinstall the rubber pad before welding. After welding, the welding head moves up, the operator takes out the welded product, repeats the above operation, puts the welded part back in the welding seat, and welds the next product. On the one hand, the use of light sensing detection technology, due to its high sensitivity, can detect the missing rubber pad before the welding process, which can accurately and effectively avoid the production of defective products; on the other hand, the use of positioning seat for contour positioning can achieve higher welding accuracy and efficiency, and the manual positioning method is no longer used during the welding process, which ensures welding quality and improves production efficiency.
[0011] Preferably, a guide tube is installed at one side of the front center of the positioning seat, and the inner ends of the guide tubes penetrate the outer wall of the positioning seat and extend inwards. The corresponding medium can be introduced into the interior of the positioning seat through the guide tubes.
[0012] Preferably, the top rear end of the guide tube is evenly provided with round holes, which are located directly below the bottom of the optical head, and a pad is installed at the rear end of the bottom center of the positioning seat. Air can be introduced into the guide tube and sprayed toward the optical head through the round hole, so as to clean the dust that falls on the surface of the optical head, and avoid dust covering the surface of the optical head and blocking part of the light, resulting in a weakening of the light intensity received by the optical head, which will affect the measurement accuracy of the optical head, making it unable to correctly perceive the intensity of the ambient light, and avoiding the occurrence of errors in the detection of the rubber pad.
[0013] Preferably, a connecting circular plate is installed at the front end of the guide tube, and an air inlet end is provided at the front center of the connecting circular plate. The air inlet end of the connecting circular plate can be connected to external equipment such as a fan to introduce air into the guide tube.
[0014] Preferably, an outer blocking plate is added to the air inlet end of the connecting circular plate, and connecting holes are opened inwardly on all sides of the front of the connecting circular plate. When not in use, an outer blocking plate can be added to the air inlet end of the connecting circular plate to prevent air from carrying dust into the interior of the guide tube and affecting the cleaning effect of the optical sensor head. At the same time, the connecting hole can be used to connect with external equipment such as a fan.
[0015] (III) Beneficial effects
[0016] Compared with the prior art, the utility model provides a welding tool with a light-sensing error-proofing mechanism, which has the following beneficial effects:
[0017] 1. The welding tool with light-sensing error-proofing mechanism is operated by the operator to first place the rubber pad in the middle groove of the welding shell, and then place the welding iron sheet on the rubber pad. The small column on the welding shell corresponds to the small hole of the welding iron sheet. Then the welding shell, rubber pad and welding iron sheet are placed together in the positioning groove of the positioning seat. The positioning seat is fixed on the welding workbench by fixing screws; then press the welding button. If the light-sensing head senses that the environment is dark at this time, after processing by the light-sensing sensor, it proves that the rubber pad is not missing at this time. The welding machine drives the welding head downward. If the light-sensing head senses that the environment is bright at this time, it proves that the rubber pad is missing at this time. After processing by the light-sensing sensor, The sensor triggers the alarm of the welding machine. The operator takes out the welded part for inspection and reinstalls the rubber pad before welding. After welding, the welding head moves up, and the operator takes out the welded product and repeats the above operation. The welded part is placed in the welding seat again to weld the next product. In this way, on the one hand, the light sensing detection technology can detect the missing rubber pad before the welding process due to its high sensitivity, which can accurately and effectively avoid the production of defective products. On the other hand, the positioning seat is used for contour positioning, which has higher welding accuracy and efficiency. The manual positioning method is no longer used during the welding process, which ensures the welding quality and improves the production efficiency.
[0018] 2. The welding tool with a light-sensing error-proofing mechanism is connected to external equipment such as a fan by connecting the air inlet end and the connecting hole of the circular plate, introducing air into the guide tube and spraying it to the light-sensing head through the circular hole to clean the dust that falls on the surface of the light-sensing head. When not in use, an external blocking plate can be added to the air inlet end of the circular plate. In this way, dust can be prevented from covering the surface of the light-sensing head and blocking part of the light, resulting in a decrease in the intensity of light received by the light-sensing head, which will affect the measurement accuracy of the light-sensing head and make it unable to correctly perceive the intensity of the ambient light, thereby avoiding the occurrence of errors in the detection of the rubber pad.
