Description

[Technical field]

[0001] The invention relates to the field of automatic molding plug-in equipment, in particular to a feeding device for an plug-in machine. [Background technology]

[0002] The feeders of the plug-in machines on the market are composed of multiple cylinders, which are prone to jamming, and the lengths of the pins after cutting are different. At the same time, they are limited by the air pressure in the factory, the cylinders are easy to wear, and the solenoid valves have short lifespans, which makes their use very unstable. In addition, the existing popular feeders on the market often have problems with electronic components during transportation and before and after molding. The parts structure is complex, and many screws are used, which increases the risk of wear. In the production process, the cylinders even conflict with each other, and the production is stopped due to loose structures, resulting in time waste and increased personnel costs. [Summary of the invention]

[0003] The technical problem to be solved by the present invention is to provide a feeding device for an insertion machine with a simple structure and stable transmission.

[0004] The object of the present invention is achieved in that:

[0005] A feeding device for an insertion machine comprises a cutting assembly for cutting pins of electronic components to separate the electronic components from an electronic material tape, a conveying assembly for conveying the electronic material tape to the cutting assembly, and a synchronous driving assembly arranged at the bottom sides of the cutting assembly and the conveying assembly and used to drive the cutting assembly and the conveying assembly to move, wherein the synchronous driving assembly comprises a driving shaft, a driver arranged at one end of the driving shaft and used to control the rotation of the driving shaft, and a first driving wheel and a second driving wheel arranged on the driving shaft and used to drive the cutting assembly and the conveying assembly to move, respectively.

[0006] The present invention adopts the above structure, the driver drives the driving shaft to rotate, thereby driving the first driving wheel and the second driving wheel to rotate synchronously, the rotation of the second driving wheel drives the transmission component to move to transmit the electronic material tape with electronic components to the cutting component, and the rotation of the second driving wheel drives the cutting component to move to cut the pins of the electronic components to separate the electronic components from the electronic material tape. Therefore, the present invention can realize the coordinated work of material tape transmission and device cutting through one power source, and its structure is simple and the transmission is stable.

[0007] In the feeding device of the insertion machine as described above, the first driving wheel is provided with an annular guide groove along its circumference for the bottom of the shearing assembly to abut against, and the annular guide groove is provided with a protrusion for pressing the shearing assembly to make the shearing assembly move. When the first driving wheel rotates, when the protrusion rotates to the bottom of the shearing assembly, the protrusion will lift the shearing assembly to make the shearing assembly move and shear the pins of the electronic components.

[0008] In a feeding device for an insertion machine as described above, the second driving wheel is provided with two opposite semicircular grooves along its circumference, the bottom of the transmission component is in contact with the semicircular grooves, and the two semicircular grooves are connected at their ends with a rotary groove so that the transmission component can move between the two semicircular grooves. The rotation of the second driving wheel can drive the transmission component to move along the semicircular grooves and the rotary grooves, so that the transmission component can reciprocate back and forth, thereby transmitting the electronic material strip to the shearing component.

[0009] In the above-mentioned insertion machine feeding device, the axial distance between the two semicircular grooves is P, and 12.7mm≤P≤15mm, so as to adapt to the sizes of most electrical material strips.

[0010] In a feeding device for an insertion machine as described above, the shearing assembly includes a fixed seat, a first abutment column passing through the fixed seat and abutting against the annular guide groove, and a cutter abutting against the first abutment column. When the protrusion rotates to the bottom of the first abutment column, the protrusion will lift the first abutment column, and the first abutment column will push the cutter outward, so that the cutter cuts the pins of the electronic components.

[0011] In the above-mentioned insertion machine feeding device, the transmission component includes a guide seat, a slide seat slidably arranged on the guide seat, a second abutting column with one end abutting against the semicircular groove or the rotary groove and the other end connected to the slide seat, and an active ratchet arranged on the side of the slide seat and used to engage with the electronic material belt and transmit the electronic material belt to the shearing component. The rotation of the second driving wheel can drive the second abutting column to move along the semicircular groove and the rotary groove, so that the second abutting column, the slide seat and the active ratchet move back and forth relative to the guide seat, and when the active ratchet moves forward, the electronic material belt is transmitted to the shearing component under the engaging action of the active ratchet.

[0012] In the above-mentioned insertion machine feeding device, the first abutment column is provided with a guide slope for the cutter to abut against. When the protrusion rotates to the bottom of the first abutment column, the protrusion will lift the first abutment column, and when the first abutment column is lifted, the cutter is pushed outward through the guide slope, thereby ensuring that the cutter cuts the pins evenly.

[0013] In a feeding device for an insertion machine as described above, the cutter is provided with a first pulley group that can roll relative to the guide inclined surface, thereby improving the smoothness of transmission between the cutter and the first abutment column, and the bottom of the first abutment column is provided with a second pulley group that can roll relative to the annular guide groove, thereby improving the smoothness of transmission between the first abutment column and the annular guide groove.

[0014] In the above-mentioned insertion machine feeding device, the bottom of the second abutment column is provided with a third pulley group that can roll relative to the semicircular groove and the rotary groove, thereby improving the smoothness of transmission between the second abutment column and the semicircular groove and the rotary groove.

[0015] In the above-mentioned insertion machine feeding device, a non-return pawl is provided on one side of the shearing assembly to prevent the electronic material strip from retreating, thereby effectively preventing the electronic material strip from being transmitted backward and ensuring the stability of its transmission.

[0021] A feeding device for an insertion machine comprises a cutting assembly 1 for cutting pins of an electronic component 101 so as to separate the electronic component 101 from an electronic material tape 10, a conveying assembly 2 for conveying the electronic material tape 10 to the cutting assembly 1, and a synchronous driving assembly 3 arranged at the bottom sides of the cutting assembly 1 and the conveying assembly 2 and used to drive the cutting assembly 1 and the conveying assembly 2 to move. The synchronous driving assembly 3 comprises a driving shaft 31, a driver 32 arranged at one end of the driving shaft 31 and used to control the rotation of the driving shaft 31, and a first driving wheel 33 and a second driving wheel 34 arranged on the driving shaft 31 and used to drive the cutting assembly 1 and the conveying assembly 2 to move, respectively.

[0022] In order to enable the shearing assembly 1 to quickly shear the pins of the electronic component 101 when the first driving wheel 33 rotates, the first driving wheel 33 is provided with an annular guide groove 331 along its circumference for the bottom of the shearing assembly 1 to abut against, and the annular guide groove 331 is provided with a protrusion 332 for pressing the shearing assembly 1 to make the shearing assembly 1 move.

[0023] In order to enable the conveying component 2 to reciprocate back and forth to convey the electronic material strip 10 to the shearing component 1, the second driving wheel 34 is provided with two opposite semicircular grooves 341 along its circumference, and the bottom of the conveying component 2 is in contact with the semicircular grooves 341. The two semicircular grooves 341 are connected at their ends with a rotating groove 342 so that the conveying component 2 can move between the two semicircular grooves 341.

[0024] In order to adapt to the size of most electronic material strips, the axial distance between the two semicircular grooves 341 is P (the axial distance P is equal to the spacing between two adjacent electronic components 101 on the electronic strip 10), and 12.7mm≤P≤15mm.

[0025] Preferably, the shearing assembly 1 includes a fixing seat 11 , a first abutting post 12 passing through the fixing seat 11 and abutting against the annular guide groove 331 , and a cutting knife 13 abutting against the first abutting post 12 .

[0026] Preferably, the conveying assembly 2 comprises a guide seat 21, a slide seat 22 slidably disposed on the guide seat 21, a second abutting column 23 having one end abutting against the semicircular groove 341 or the rotary groove 342 and the other end connected to the slide seat 22, and an active ratchet 24 disposed on the side of the slide seat 22 and used to engage with the electronic material tape 10 and convey the electronic material tape 10 to the shearing assembly 1. The electronic material tape 10 is provided with a clamping hole 100 along its length direction for the inclined clamping block of the active ratchet 24 to engage, and the spacing between two adjacent clamping holes 100 is equal to the axial distance P and the spacing between two adjacent electronic components 101 on the electronic material tape 10.

[0027] In order to ensure that the cutter 13 cuts the pins evenly, a guiding inclined surface 121 for the cutter 13 to abut against is provided on the first abutting column 12 .

[0028] In order to improve the smoothness of transmission between the cutter 13 and the first abutment column 12, the cutter 13 is provided with a first pulley group 131 that can roll relative to the guide inclined surface 121. In order to improve the smoothness of transmission between the first abutment column 12 and the annular guide groove 331, a second pulley group 122 that can roll relative to the annular guide groove 331 is provided at the bottom of the first abutment column 12.

[0029] In order to improve the stability of transmission between the second abutting column 23 and the semicircular groove 341 and the rotating groove 342 , a third pulley set 231 that can roll relative to the semicircular groove 341 and the rotating groove 342 is provided at the bottom of the second abutting column 23 .

[0030] In order to effectively prevent the electronic material 10 from being transported back and ensure the stability of its transportation, a non-return pawl 4 is provided on one side of the shearing assembly 1 to prevent the electronic material 10 from retreating (the structure of the non-return pawl 4 is the same as that of the active pawl 24, and both are provided with an inclined card block that can be elastically connected to the card hole 100 on the electronic material strip 10).

[0031] Preferably, the driver 32 is a motor, and a gear transmission set 321 is provided between the output end of the motor and the end of the driving shaft 31 .

[0032] When the present invention is used, the driver 32 drives the driving shaft 31 to rotate, thereby driving the first driving wheel 33 and the second driving wheel 34 to rotate synchronously. When the protrusion 332 rotates to the bottom of the first abutting column 12, the protrusion 332 will lift the first abutting column 12, and the first abutting column 12 will push the cutter 13 outward, so that the cutter 13 shears the pins of the electronic component 101 to separate the electronic component 101 from the electronic material belt 10, thereby feeding the insertion machine. At the same time, when the second driving wheel 34 rotates, the second abutting column 23 moves along the semicircular groove 341 and the rotary groove 342, so that the second abutting column 23, the slide seat 22 and the active ratchet The claw 24 reciprocates back and forth relative to the guide seat 21. When the active ratchet 24 moves forward (toward the direction of the shearing assembly 1), the electronic material strip 10 is transferred to the shearing assembly 1 (the bottom of the electronic material strip 10 is provided with a guide groove for supporting and fixing the electronic material strip 10) under the clamping action of the active ratchet 24 (the active ratchet 24 is clamped with the clamping hole 100 on the electronic material strip 10). During the transmission process, the non-return ratchet 4 is also clamped with the clamping hole 100, effectively preventing the electronic material strip 10 from retreating. When the active ratchet 24 moves backward (toward the opposite direction of the shearing assembly 1), the active ratchet 24 is disengaged from the clamping hole 100 and re-clamped on the next clamping hole 100. A sensor 102 for sensing the electronic component 101 can be provided on the opposite side of the shearing assembly 1, and the sensor 102 is electrically connected to the driver 32 to control its start and stop.
