Description

Technical Field

[0001] The invention relates to the technical field of electric switch groups, and in particular to a contact switch assembly production device. Background Art

[0002] A contact switch is a switch that uses metal contacts to open or close a circuit, interrupt current or make it flow to other circuits. It controls the on and off of the circuit through mechanical contact. When the switch is operated (such as pressing a button or toggling), the internal contact points will contact or separate, thereby closing or disconnecting the circuit. Contact switches are one of the commonly used components on equipment and instruments, and the demand is very huge.

[0003] In the conventional production process of these contact switches, workers need to manually assemble the various parts together, which is inefficient, labor-intensive, and has a high scrap rate. Mechanical automation has become a development trend and is gradually replacing traditional manual labor; how to better realize the mechanized assembly of contact switches and improve the level of automated assembly of contact switches has become an urgent problem to be solved.

[0004] For example, the patent publication number CN118578119A discloses a "switch base press-fitting device and its use method", which utilizes the structure on each bracket in the press-fitting assembly to assemble each part separately, has a loading and positioning function, and can accurately assemble each part in sequence, thereby improving assembly efficiency, ensuring assembly stability, and improving product quality.

[0005] For example, the "push button switch assembly machine" disclosed in patent announcement number CN209648090U, the upper cover assembly mechanism, the lower cover assembly mechanism and the assembly mechanism complete the assembly operation of the push button switch, and better realize the mechanized assembly of the push button switch accessories;

[0006] The various existing contact switch assembly lines are only suitable for specific models, and the efficiency is low when the contact switch model assembly line needs to be replaced; during the automatic assembly process of the contact switch, the contact switch needs to be tinned. Excessive tinning of the contact switch will cause a tin bridge to form between the contact points of the switch, resulting in poor contact. Excessive tinning of the contact switch may cause connection to contacts that should not be connected, resulting in a short circuit.

[0007] Therefore, an automatic assembly line is needed that can ensure good tinning effect of contact switches. Summary of the invention

[0074] like Fig.14 As shown, the left end of the conveyor belt assembly 74 is the input end, and the right end is the output end.

[0075] Two groups of limit blocks 721 are fixedly arranged on the top of the support seat 72, and the spacing between the two groups of limit blocks 721 is adapted to the width of the cavity substrate 75. The top of the cavity substrate 75 is provided with multiple groups of cavity grooves at equal intervals in the longitudinal direction, and the cavity grooves are adapted to the contact switch 800;

[0076] The first vertical lifting assembly 76 is relatively located at the input end of the conveyor belt assembly 74 (on the left side of the limit block 721), and the upward output end of the first vertical lifting assembly 76 is connected to the limit member 79, and the limit member 79 is relatively located at the interval between the two groups of conveyor belt assemblies 74; the upward output end of the second vertical lifting assembly 77 is relatively located at the interval between the two groups of conveyor belt assemblies 74; the upward output end of the third vertical lifting assembly 78 is connected to the limit top plate 711, and the limit top plate 711 is relatively located above the limit block 721, and a positioning column extending downward is provided at the bottom of the limit top plate 711, and a positioning hole adapted to the positioning column is opened at the top of the cavity substrate 75;

[0077] The fourth vertical lifting assembly 710 is relatively located at the output end of the conveyor belt assembly 74 (to the right of the limit block 721 ), and a corresponding limit member 79 is installed at the upward output end of the fourth vertical lifting assembly 710 , which is relatively located at the interval between the two groups of conveyor belt assemblies 74 .

[0078] Working principle:

[0079] The previous process transports a row of contact switches 800 arranged at equal intervals in the longitudinal direction to an initial position.

[0080] The first transverse moving assembly 11 drives the clamping mounting plate 13 to move to the initial position, and the angle rotating assembly 15 drives the first rotating shaft 16 to rotate, so that the fixed claw 171 and the movable claw 18 are in a vertical downward state, and then the first vertical moving assembly 12 drives the clamping mounting plate 13 to descend vertically, and the fixed claw 171 and the movable claw 18 cooperate to clamp a contact switch 800 under the action of the spring 19; the space formed by the downward free end of the movable claw 18 and the clamping groove of the downward left part of the fixed claw 171 is sleeved on the outer wall of the contact switch 800, and a certain pressure is applied by the spring 19 to prevent it from detaching. At this time, the contact switch 800 is clamped and fixed by the left and right limit clamps.

[0081] Afterwards, the first transverse moving assembly 11 and the first vertical moving assembly 12 cooperate to drive the clamped row of contact switches 800 to move to the inner cavity of the tin pot 21, so that the lower surface of the clamped contact switches 800 adheres to the tin liquid.

[0082] The heater 22 heats the tin liquid in the inner cavity of the tin pot 21, and the external positive pressure air source is transported to the tin liquid in the inner cavity of the tin pot 21 through the ventilation pipe 23. The bubbles flow upward to take away the gas and impurities in the tin liquid, thereby reducing the bubbles and inclusions in the tin liquid and improving the purity of the tin liquid; the first longitudinal movement component 24 drives the scraper 25 to move longitudinally, and scrapes off a layer of tin oxide film formed by oxidation on the upper surface of the tin liquid to the edge, avoiding the moving range of the contact switch 800; the second vertical movement component 26 drives the tin pot 21 to move vertically, and can relatively adjust the distance between the scraper 25 and the upper surface of the tin liquid in the tin pot 21.

[0083] After the lower surface of the clamped contact switch 800 adheres to the tin liquid and is separated from the tin pot 21, the angle rotation component 15 drives the first rotating shaft 16 to rotate 180 degrees, so that the lower surface of the contact switch 800 originally adhered to the tin liquid is turned over to the upper surface, and at the same time, the contact switch 800 clamped by the fixed claw 171 and the movable claw 18 just moves to the corresponding limiting groove 141 of the limiting clamping plate 14. Therefore, the contact switch 800 is limited in three directions to improve the clamping stability.

[0084] Afterwards, the first transverse moving assembly 11 drives the clamping mounting plate 13 to move below the grinding assembly 300, the third vertical moving assembly 31 drives the grinding wheel 33 to descend and abut against the upper surface of the contact switch 800, and the grinding rotating assembly 32 drives the grinding wheel 33 to rotate to grind the tinned upper surface of the contact switch 800. At this time, the clamping groove of the fixed claw 171 vertically supports the contact switch 800. One grinding wheel 33 can grind a row of contact switches 800 at the same time.

[0085] After the grinding is completed, the third vertical moving assembly 31 drives the grinding wheel 33 to rise and reset, and the angle rotating assembly 15 drives the first rotating shaft 16 to rotate 180 degrees in the opposite direction, so that the side of the contact switch 800 adhering to the tin liquid is turned over to the lower surface. Then, the first horizontal moving assembly 11 and the first vertical moving assembly 12 cooperate to drive the clamped row of contact switches 800 to move into the medicine box 41 and place them in the receiving seat 42; Fig.18 As shown, the cross-sectional shape of the contact switch 800 is similar to an "I-shaped" shape. The flange of the contact switch 800 is driven to be inserted into the straight slot 421 of the accommodation seat 42, and then the first vertical movement component 12 drives the clamping mounting plate 13 to move upward. At this time, the contact switch 800 is vertically limited by the straight slot 421, so that the contact switch 800 is separated from between the fixed claw 171 and the movable claw 18 and remains in the inner cavity of the accommodation seat 42;

[0086] Afterwards, the fourth vertical moving assembly 43 drives the accommodating seat 42 to vertically descend and complete immersion in the liquid medicine, and the liquid medicine removes the residual impurities of the polished contact switch 800 to ensure the cleanliness of the surface of the contact switch 800.

[0087] After cleaning is completed, the fourth vertical moving assembly 43 drives the receiving seat 42 to rise vertically and reset to be separated from the liquid medicine;

[0088] Then the sixth vertical moving assembly 63 drives the elastic vacuum suction nozzle 64 to descend, and the elastic vacuum suction nozzle 64 abuts and cooperates with the contact switch 800 in the inner cavity of the receiving seat 42 directly below, and the elastic vacuum suction nozzle 64 fixes the contact switch 800 by negative pressure adsorption; then the sixth vertical moving assembly 63 and the sixth horizontal moving assembly 61 cooperate to drive the contact switch 800 adsorbed by the elastic vacuum suction nozzle 64 to move between the two groups of water-absorbing brush rollers 52, and the driving motor 55 drives the two water-absorbing brush rollers 52 to rotate in the opposite direction through the driving gear 54 and the driven gear 53, and the two water-absorbing brush rollers 52 rotate to wipe a row of contact switches 800 adsorbed by the elastic vacuum suction nozzle 64. When not in use, the fifth vertical moving assembly 56 drives the driving motor 55 to rise a certain distance, so that the driving gear 54 is separated from the driven gear 53.

[0089] After wiping is completed, the contact switch 800 adsorbed by the elastic vacuum nozzle 64 is moved to the cavity groove of the cavity substrate 76 with the cooperation of the sixth vertical movement component 63 and the sixth horizontal movement component 61, so that a row of contact switches 800 are placed on the top of the cavity substrate 76. If the clamped contact switch 800 deviates slightly from the cavity groove, the support seat 72 can be moved longitudinally by the second longitudinal movement component 71 for adjustment; at this time, the cavity substrate 76 is relatively located between the two sets of limit blocks 721.

[0090] Afterwards, the two sets of conveyor belt assemblies 74 cooperate to convey the cavity substrate 76 located on the upper surface thereof outward.

[0091] Subsequently, a new group of cavity substrates 76 are transported from the outside to between the two groups of limit blocks 721 through the conveyor belt assembly 74, and the third vertical lifting assembly 78 drives the limit top plate 711 to descend, so that the positioning column is inserted into the positioning hole of the cavity substrate 76. At this time, the cavity substrate 76 will not be driven by the conveyor belt assembly 74 to continue to move forward;

[0092] Afterwards, the first vertical lifting assembly 76 drives the stopper 79 at its output end to rise above the conveyor assembly 74, and the stopper 79 blocks the subsequent new cavity substrate 76 from entering between the two sets of stoppers 721;

[0093] In order to avoid friction between the rotation of the conveyor belt assembly 74 and the fixed bottom surface of the cavity substrate 76, the output end of the second vertical lifting assembly 77 rises, and the output end of the second vertical lifting assembly 77 rises to lift the cavity substrate 76 located between the two sets of limit blocks 721 to rise and separate from the conveyor belt assembly 74; after the cavity substrate 76 is equipped with a contact switch 800, it falls to the conveyor belt assembly 74, and the third vertical lifting assembly 78 drives the limit top plate 711 to rise so that the positioning column is separated from the positioning hole of the cavity substrate 76.

[0094] The conveyor belt assembly 74 is used to drive the cavity substrate 76 equipped with the contact switch 800 to be transported to the next process. A set of fourth vertical lifting assemblies 710 are arranged at the output end of the conveyor belt assembly 74. The fourth vertical lifting assembly 710 drives the corresponding limit member 79 to rise and fall, and can control the cavity substrate 76 of the conveyor belt assembly 74 to be transported to the next process.

[0095] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
