Abstract
The utility model discloses a support thimble applied to a surface mount device. The support thimble comprises a base and a support pin. A fixing device is arranged below the base. The support pin and the base are fixedly connected in a height adjustable manner. The support thimble has the advantages of simple structure, low cost and convenient use, can be applied to the vast majority of SMT production devices, and has a wide application range.
Description
Technical field
The utility model relates to a kind of printed circuit board fabrication equipment, particularly a kind of support pin for surface-mounting equipment.
Background technology
Along with extensively popularizing of various electronic equipments, surface mounting technology (Surface Mounted Technology " SMT ") has obtained using more and more widely.SMT has been penetrated into every field as circuit assembly technology of new generation, and the SMT product has that compact conformation, volume are little, vibration resistance, shock resistance, and high frequency characteristics is good, the production efficiency advantages of higher.SMT has occupied the leading position in circuit board dress connection technique, be most popular a kind of technology and technique in present Electronic Assemblies industry.Along with the diversification of the market demand, the kind of product is more and more, and precision is more and more higher.
In prior art, the incidental spare part of equipment can not satisfy present requirements sometimes.For example, some cell phone mainboards, PCB upper element in two sides is all quite intensive.Production equipment is too intensive because of the first surface device when printing second, can't support to the appropriate location on PCB, badly influences the quality of printing.The technical staff solves problem by the printing apparatus of tailor-made this PCB sometimes, yet, if each product is made a printing apparatus, the cost of cost will strengthen so, and the frequency of model change is accelerated, printing apparatus before regenerating is discarded waste often, and the stacking of various tools management simultaneously is also a no small problem.
Those skilled in the art develops urgently a kind of new device for the support circuit plate and addresses the above problem to a certain extent.
The utility model content
The technical problems to be solved in the utility model is in order to overcome in prior art, and the support jig cost of surface mounting technology (SMT) is high, and the deficiency that should not manage provides a kind of support pin for surface-mounting equipment.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of support pin for surface-mounting equipment, its characteristics be, described support pin comprises a base and a supporting pin, and described base below arranges a fixture, is fixedly connected with in height-adjustable mode between described supporting pin and described base.
Preferably, the fixture of described base for supporting below is one to inhale magnetite, and described suction magnetite is fixedly installed in one container cavity of described base below.Inhale magnetite can with operating platform on steel plate or other magnetic material adhesives, reach thimble be fixed on purpose on operating platform.
Preferably, described supporting pin comprises a first end and a second end, and described first end arranges external screw thread, and described base arranges internal thread, described supporting pin with described base for being threaded.By the rotation screw thread, the height of the relative base of supporting pin can be regulated.
Preferably, described supporting pin also arranges a nut, described nut and supporting pin be spirally connected and with the base butt.
Preferably, described supporting pin diameter is 3.85mm, and described nut internal diameter is 3.85mm, and described suction magnetite is cylindrical, and diameter is 15mm, is highly 7.9mm.
Preferably, the material of described supporting pin is stainless steel.
On the basis that meets this area general knowledge, above-mentioned each optimum condition, but combination in any namely get each preferred embodiments of the utility model.
Positive progressive effect of the present utility model is: this support pin is simple in structure, and is with low cost, easy to use, can be applied to most SMT production equipments, applied range.
Description of drawings
Fig. 1 is the structural representation of the support pin under specific embodiment of the utility model, and wherein nut is not yet installed.
Fig. 2 is the structural representation of the support pin under specific embodiment of the utility model, and wherein nut is installed.
Embodiment
Embodiment of the present utility model describes with reference to the accompanying drawings.In Figure of description, the element with similar structures or function will represent with identical component symbol.Accompanying drawing is each embodiment of the present utility model for convenience of explanation just, is not to carry out to the utility model the explanation of exhaustive, neither limit scope of the present utility model.
Fig. 1 shows the schematic structure of the support pin under specific embodiment of the utility model, in this embodiment, support pin comprises base 10 and supporting pin 20, base 10 arranges screw 12, one end of supporting pin 20 arranges external screw thread 22, external screw thread 22 is spirally connected with screw 12, and operating personnel can regulate by the rotation screw thread height of supporting pin 20.The shape of the other end 24 of supporting pin can be cylinder, can be also the shape of other suitable support circuit plate, and for example, it is spherical, oval or can embed the sharp shape of PCB location hole that the supporting pin top can be set to semicircle.
In one embodiment, supporting pin is stainless steel material, and base can be stainless steel material, can be also other suitable metal material.
Fig. 1 shows the schematic structure of support pin, in this embodiment, the internal diameter of nut 30 and the external screw thread of supporting pin coupling, after in the screw that is threaded into base 10 of supporting pin, nut 30 screws in the thread root of supporting pin, until offset with base, like this, nut 30 firmly fixes supporting pin and base together, avoids supporting pin to rock on base.The material shape of nut 30 is not limit, as long as energy immovable anchor pin and base are all applicable.
It will be appreciated by those skilled in the art that, other fixture can be passed through in base 10 belows, for example, a plurality of screws or thread groove are set on platform, base arranges external screw thread, like this, base can be fixed with operating platform so that the mode that is spirally connected is fixing, also can be fixedly connected with such as height-adjustable modes such as travellers by other between supporting pin 20 and base 10.
In a preferred embodiment, supporting pin 20 diameters are 3.85mm, and nut 30 internal diameters are 3.85mm, and it is cylindrical inhaling magnetite, and diameter is 15mm, is highly 7.9mm.
During use, operating personnel utilize the suction magnetite that thimble is placed on preposition on platform, and supporting pin is adjusted to suitable height, subsequently PCB are placed on thimble, and next just can print on PCB or paster etc. operated.
Those skilled in the art will appreciate that the technical program not only can be applied on the SMT manufacturing equipment, can be applied in equally other and need to carry out to product the occasion of the support of adjustable position.
Although more than described embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is limited by appended claims.Those skilled in the art can make various changes or modifications to these execution modes under the prerequisite that does not deviate from principle of the present utility model and essence, but these changes and modification all fall into protection range of the present utility model.
