TECHNICAL FIELD

[0001] The utility model relates to an inductive switch, in particular to a contact type mechanical inductive switch for a mechanical hand. BACKGROUND

[0002] In industrial production equipment, such as ALD equipment, the inductive switch is one of the important parts. In the process of moving products or transporting products by the mechanical hand, the state can be accurately fed back, such as distance feedback, in-place feedback, position feedback, presence feedback, safety feedback, etc.

[0003] In the prior art, the mechanical hand needs to grab products in a high-temperature environment. For the inductive switch, there are problems such as high temperature, narrow installation space, etc., and the inductive switch acts on the surface of the measured object, which may cause displacement of the installation body or the measured object. The inductive switch of the prior art cannot effectively meet the above use needs. SUMMARY

[0004] The utility model provides a contact type mechanical inductive switch, which aims to overcome the above-mentioned deficiencies in the prior art and meet the working needs of the ALD equipment mechanical hand.

[0005] The technical solution of the utility model is a contact type mechanical inductive switch, which comprises a second main body part and a first main body part connected in an up-down manner. The first main body part is provided with a sliding groove passing through up and down, and a striker is slidably connected in the sliding groove. A neodymium magnet is installed on the top end of the striker through a fastening screw. The bottom end of the striker extends to the lower side of the first main body part. A spring is installed on the bottom of the second main body part corresponding to the sliding groove of the first main body part. The bottom of the spring presses the neodymium magnet. A dry reed tube inductor is installed in the installation groove on the side of the first main body part close to the striker. The top of the dry reed tube inductor passes through the gap in the second main body part and extends to the upper side of the second main body part.

[0006] Preferably, the whole is made of metal material. Good high-temperature resistance can be achieved.

[0007] Preferably, a heat reflecting cover is installed on the whole side surface of the second main body part and the first main body part outside the dry reed tube inductor. The heat reflecting cover can reflect heat and further protect the dry reed tube inductor from high temperature.

[0008] Preferably, a roller is installed on the bottom end of the striker through a pin. Direct collision can be avoided to prevent damage.

[0009] The utility model has the advantages of reasonable structure design, compact size, batch production, low production cost, fast inductive response, and application in high-temperature environment and narrow space. BRIEF DESCRIPTION OF DRAWINGS

[0015] The utility model will be further explained in detail in combination with embodiment and specific implementation.

[0016] As Figures 1-4 Shown, a kind of contact type mechanical induction switch, overall is metal material, its structure includes the second main part 6 and first main part 1 connected in upper and lower, wherein first main part 1 is equipped with the sliding slot that passes through in upper and lower, sliding slot is slidably connected with striker 3, striker 3 top end is installed with neodymium magnet 2 by fastening screw 10, striker 3 bottom end extends to the first main part 1 below and is installed with gyro wheel 4 by pin 9, spring 8 is installed in the sliding slot of first main part 1 of second main part 6 bottom, neodymium magnet 2 is pressed tightly in spring 8 bottom, dry reed tube inductor 5 is installed in the installation groove of the side of first main part 1 close to striker 3, dry reed tube inductor 5 top portion passes through the accommodation slot on second main part 6 and extends to the above of second main part 6, heat reflecting cover 7 is installed on the overall side of second main part 6 and first main part 1 outside dry reed tube inductor 5.

[0017] According to above structure, when working, dry reed tube inductor 5 is triggered to normal state after electrification, then spring 8 is compressed after striker 3 end is subjected to pressure, neodymium magnet 2 installed at top end is separated from dry reed tube inductor 5 following striker 3, then break off induction, to realize the function of switch. When being used for ALD equipment mechanical hand, the feedback that whether product is grabbed in place can be detected.

[0018] Overall metal material can realize better high temperature resistance.

[0019] Heat reflecting cover 7 can reflect heat, further protect dry reed tube inductor 5 from high temperature influence.

[0020] Striker 3 bottom end installs gyro wheel 4, can avoid direct collision and cause damage.

[0021] The above described components are all prior art, and a person skilled in the art can use any model and prior design that can achieve the corresponding functions.

[0022] The above described is only the preferred embodiment of the present application, it should be pointed out that, for those of ordinary skill in the art, without departing from the inventive concept of the present application, can make a number of deformation and improvement, these all belong to the protection scope of the present application.
