After having adopted technique scheme; The utlity model has following beneficial effect: adopt the reflection ray sensor to discern gap position on the housing in the gumming mechanism of (1) the utility model to judge the position of housing; To rotate tool again rotates to an angle according to program setting; Thereby motor can be automatically rotates to housing and reaches the follow-up wheel that is transported on the preset direction and change the requirement of laying on the tool, thereby has guaranteed the degree of accuracy and the high efficiency of follow-up assembly working.

(2) buzzer need be laid piezo, therefore in the housing of gluing when assembling; If will realize the production line of the complicated automation assembling of buzzer, the piezo placing mechanism will be a wherein requisite part, and the utility model is placed on piezo on the automatic charging device; And be placed in the buzzer housing through Handling device absorption piezo and with it, barrel be positioned at linear stepping motor directly over, linear stepping motor starts during material loading; The motor screw mandrel will jacking be positioned at the pallet of barrel, thereby guarantees the automatic continuous material loading of piezo, and the photoinduction sheet is fixed on the side of pallet; And be slidingly connected with long groove, reflective optical sensor is over against the long groove of barrel, when the barrel over against linear stepping motor lacks material; Photoinduction sector-meeting on the pallet triggers photoelectric switching signal, makes the withdrawal of motor screw mandrel, level transposition cylinder action then; Another barrel is delivered to the feed position, further guaranteed the automatic continuous material loading of piezo; Handling device has been realized moving horizontally of suction nozzle through the driving of carrying cylinder and lift cylinder, and the rise and fall action; Simple in structure; Move reliable and stablely, so the utility model realized the automatic charging of piezo and laid automatically, makes this piezo placing mechanism can become a part of the automatic assembly line of a kind of buzzer; Practice thrift the labour, improved operating efficiency and product quality.

(3) 2 contact pins to be installed on the buzzer; This contact pin is that an end connects, and the structure of an end bifurcated is welded on the piezo after the thin needs bending; Be used for installing and energized after thick needs cover the preceding paragraph thermoplastic tube; Therefore need contact pin form as requested is placed to the mechanism on the buzzer, lay, and can guarantee quality and the final quality of buzzer that contact pin is laid to realize high efficiency, full-automatic buzzer contact pin; The utility model is placed on the buzzer contact pin on the contact pin placement platform; Through contact pin Handling device gripping contact pin; Again through contact pin bending device with its bending, and then the contact pin that is clipped after the bending by Handling device is placed in the buzzer housing, realized the automatic bending of contact pin and lays automatically; Because the housing of buzzer is not complete symmetrical structure; The riding position of two contact pins is also asymmetric, but forms certain oblique angle, satisfies laying of oblique contact pin if the tool that will be placed with the buzzer housing behind the contact pin bending again rotated to an angle; Design and control for tool will be very complicated; And cost is too high, so the utility model comprises two contact pin carrying mechanisms, and oblique contact pin Handling device is before inserting the buzzer housing with contact pin; Earlier contact pin is rotated a certain angle, so just can simply and reliably place contact pin.The contact pin placement platform of the utility model is provided with slide rail and two pin boards; After the contact pin on the pin board uses up, move support board, another pin board is moved to the operating position; Can carry out the bending of contact pin continuously and lay work, guarantee the continuation that contact pin is laid.And the contact pin bending device of the utility model is provided with sensor, can respond to contact pin automatically and be placed on the bending tool, improved the automaticity and the accuracy of contact pin bending, practiced thrift the labour, improved operating efficiency and product quality.

When (4) buzzer is assembled, after installing contact pin, need on the hypomere of contact pin, put thermoplastic tube and insulate,, then not only lavish labor on, and installation effectiveness be very low if install through artificial; The utility model is drop-down with thermoplastic tube through the thermoplastic tube guider; Cut off the thermoplastic tube that is enclosed within on the buzzer contact pin through the heat-shrink tube shear then; Thereby realized laying automatically of buzzer contact pin thermoplastic tube; The bottom of four ripple pearl screws all is slidingly connected with the V-knife sheet, and this structure makes the V-knife sheet when cutting off thermoplastic tube, can not misplace, and has improved operating accuracy; And clamping device is earlier flat with the thermoplastic pipe clamp before laying thermoplastic tube, thereby makes that laying of thermoplastic tube is more smooth, has further improved operating accuracy.

(5) the automatic assembly line of a kind of buzzer is when assembling buzzer; Need buzzer be placed in the tool fixture; Station is operated one by one then, and therefore, straight line wheel how to realize tool fixture changes and the moving in circles to use to become and need the difficult problem that solves of empty tool fixture; The utility model cooperates through cylinder shift module, tooth bar rotary module, has realized that the straight line wheel of tool fixture changes; Cooperate through belt conveyor, first electromagnetism carrying module and second electromagnetism carrying module, realized the use that moves in circles of empty tool fixture; Reasonable in design is compact, stable and reliable operation, the automatic assembly line high accuracy of the ability whole a kind of buzzer of extraordinary support, high efficiency production running.

(6) when one of design can be accomplished the production line of buzzer assembling automatically; Also need the buzzer of producing be detected; So that qualified and non-qualified product difference is come, this in the past detection and sorting all are that not only efficient is low by manually-operated; And human factor is many, causes the degree of accuracy of testing result to reduce; The utility model detects sorting mechanism, when bullet touches pawl when clamping plays buzzer, promptly contacts with contact pin, at this moment the buzzer energized; Whether qualified the below of monitor station is provided with the noise appearance, can test the sound that buzzer sends, and carry out judgement by the acoustic pressure detector; Qualified then product concentrates in together through the accept road, underproofly then from discarded passage, reclaims, with simple, compact structure; In the clamping carrying, buzzer is carried out the acoustic pressure detection, carried out sorting, high efficiency based on the structure that detects again; And avoided thinking factor, testing result is accurate, has guaranteed the quality of buzzer.

(7) the utility model design is ingenious, simple in structure, and the buzzer assembly line has realized the automation of height.
