Description

Technical Field

[0001] The utility model belongs to the technical field of non-standard equipment, and specifically relates to a terminal supply device. Background Art

[0002] In the manufacturing process of a certain type of connector, a single terminal with plastic needs to be sent to the assembly line and crimped with the body.

On the one hand, during the process of cutting the terminals loose, the terminals are stacked randomly, and the relative movement between the terminals increases; on the other hand, the vibration of the vibration plate also increases the relative movement between the terminals, which greatly increases the probability of damage to the coating on the terminal surface, and ultimately leads to a defective connector.

The second connecting rod 415, the third connecting rod 416 and the first telescopic cylinder 417 that drives the third connecting rod 416 to slide back and forth vertically, the connecting seat 411 is provided with a slide groove 4111, the first vacuum suction head 412 and the second vacuum suction head 413 are both slidably matched with the slide groove 4111 and slide back and forth along the first horizontal direction, one end of the third connecting rod 416 extends into the slide groove 4111 and is hinged to one end of the first connecting rod 414 and the second connecting rod 415 respectively, the other end of the third connecting rod 416 extends out of the base and is connected to the piston rod of the first telescopic cylinder 417, the first connecting rod 414 and the third connecting rod 415 are connected to the piston rod of the first telescopic cylinder 417, and the first connecting rod 414 and the third connecting rod 415 are connected to the piston rod of the first telescopic cylinder 417. The other ends of the two connecting rods 415 are hinged to the first vacuum suction head 412 and the second vacuum suction head 413 respectively; the cutting mold 10 includes a die 11, a punch 12 and a press 13 for driving the die 11 and the punch 12 to open and close, the punch 12 has an upper knife 121, the die 11 has a lower knife 111 and an avoidance hole, the lower knife 111 is used to cooperate with the upper knife 121 to cut the terminal 100 from the material strip, the avoidance hole corresponds to the lower knife 111 and is used to avoid the first vacuum suction head 412 and the second vacuum suction head 413; the die 11 has a cavity 114 below to avoid the material receiving unit 40.

[0032] like Figure 1 As shown, the first robot arm 70 and the second robot arm 90 may include a single-axis robot arm, a slide telescopic cylinder 71 connected to a slider of the single-axis robot arm, and a third vacuum suction head 72 connected to the slide telescopic cylinder 71 .

[0033] The specific structure of the cutting die 10 can be the same as that of the stamping die in the prior art, and a ditch hole can be provided at the blanking position of the terminal 100 to allow the terminal 100, the first vacuum suction head 412 and the second vacuum suction head 413 to pass through. Figure 2As shown, the punch 12 includes a P plate 122 and an S plate 123, the P plate 122 and the S plate 123 are connected by equal height screws 124, the upper knife 121 is fixed to the P plate 122, and a pressing spring 125 is provided between the P plate 122 and the S plate 123; the die 11 includes a D plate 112, the lower knife 111 is fixed to the D plate 112, and the four vertices of the S plate 123 are fixed with guide columns 14, and the four vertices of the P plate 122 and the D plate 112 are respectively provided with guide sleeves 15 that slide with the guide columns 14, and the guide sleeves 15 are provided with the guide sleeves 15 that slide with the guide columns 14. 5 and the guide column 14 ensure that the relative positions of the upper knife 121 and the lower knife 111 are accurate during the action of the press machine 13. The press machine 13 drives the P plate 122 and the upper knife 121 to move downward. The P plate 122 drives the S plate 123 to move downward through the pressing spring 125. The S plate 123 first contacts the material strip and presses the material strip during the downward movement of the P plate 122. Then, the P plate 122 and the upper knife 121 continue to move downward until the upper knife 121 cooperates with the lower knife 111 to cut off the terminal 100 on the material strip. Figure 4 shown.

[0034] By setting two vacuum suction heads, namely the first vacuum suction head 412 and the second vacuum suction head 413, in one cycle, namely the press machine 13 and the first linear drive unit 50 each operate once, two terminals 100 can be transported, and the efficiency can be doubled. However, the spacing between the terminals 100 on the material strip is not equal to the spacing between the two terminals 100 required on the assembly line. Therefore, after continuous research by the applicant, a method such as Figure 2 The suction assembly 41 shown in the figure includes a connecting seat 411, a first vacuum suction head 412, a second vacuum suction head 413, a first connecting rod 414, a second connecting rod 415, a third connecting rod 416 and a first telescopic cylinder 417 that drives the third connecting rod 416 to slide back and forth vertically. The connecting seat 411 is provided with a slide groove 4111. The first vacuum suction head 412 and the second vacuum suction head 413 are both slidably matched with the slide groove 4111 and both slide back and forth along the first horizontal direction. One end of the third connecting rod 416 extends into the slide groove 4111 and is hinged to one end of the first connecting rod 414 and the second connecting rod 415 respectively. The other end of the third connecting rod 416 extends out of the base and is connected to the piston rod of the first telescopic cylinder 417. The other ends of the first connecting rod 414 and the second connecting rod 415 are respectively hinged to the first vacuum suction head 412 and the second vacuum suction head 413. The first telescopic cylinder 417 drives the third connecting rod 416 to extend and retract, thereby driving the first vacuum suction head 412 and the second vacuum suction head 413 to open and close through the first connecting rod 414 and the second connecting rod 415, respectively, so as to match the distance between the two terminals 100 required on the assembly line. Figure 2As shown, both ends of the slide groove 4111 are provided with a limit plate 418, and the limit plate 418 is threadedly connected with an adjustment screw 419. By rotating the adjustment screw 419, the spacing between the first vacuum suction head 412 and the second vacuum suction head 413 after opening can be adjusted to match the spacing between the two terminals 100 required on the assembly line or the spacing between the two terminals 100 on the material strip. It can be understood that the spacing between the two terminals 100 after the first vacuum suction head 412 and the second vacuum suction head 413 are closed can be obtained by mechanical processing to control the size progress, which will not be repeated here.

[0035] like Figure 2 and 3 As shown, the top of the connection seat 411 has a first limiting surface 4112, and the bottom of the concave mold 11 has a second limiting surface 113. When the first limiting surface 4112 is attached to the second limiting surface 113, the top surface of the first vacuum suction head 412 and the top surface of the second vacuum suction head 413 are both attached to the bottom surface of the terminal 100 in the cutting mold 10. Therefore, the spacing between the first limiting surface 4112 and the top surface of the first vacuum suction head 412, the first limiting surface 4112 and the top surface of the second vacuum suction head 413, and the second limiting surface 113 and the top surface of the lower knife 111 is ensured by mechanical processing, so that the first vacuum suction head 412 and the second vacuum suction head 413 can accurately absorb the terminal 100 without interfering with the convex mold 12.

[0036] like Figure 2 As shown, the surface of the first vacuum suction head 412 in contact with the terminal 100 has a first suction hole 4121, and the side of the first vacuum suction head 412 is provided with a first connector hole 4122 connected to the first suction hole 4121; the surface of the second vacuum suction head 413 in contact with the terminal 100 has a second suction hole 4131, and the side of the second vacuum suction head 413 is provided with a second connector hole 4132 connected to the second suction hole 4131; the first connector hole 4122 and the second connector hole 4132 are both used to connect an air connector, so as to connect a vacuum generator or other vacuum generating device through the air connector.

[0037] The first linear drive unit 50, the second linear drive unit 80 and the third linear drive unit 42 can all adopt existing structures such as cylinders, pneumatic slides, electric slides, etc. In this embodiment, the first linear drive unit 50 and the second linear drive unit 80 both adopt single-axis robotic arms; the third linear drive unit 42 adopts a slide cylinder.

[0038] After in-depth research by the applicant, it was found that since the first vacuum suction head 412 and the second vacuum suction head 413 need to go deep into the die 11 to suck the terminal 100, the position of the terminal 100 on the first vacuum suction head 412 and the second vacuum suction head 413 may be offset during the process of cutting the terminal 100. Therefore, if the terminal 100 on the first vacuum suction head 412 and the second vacuum suction head 413 is directly transferred to the assembly line by a robot arm, poor assembly may occur due to the position offset of the terminal 100. Therefore, a transfer positioning seat 60 can be provided to correct the deviation of the terminal 100. In this embodiment, if Figure 5 and 6 As shown, the transfer positioning seat 60 includes a seat body 62 connected to the second linear drive unit 80 and a non-zero even number of carriers 61 arranged on the seat body 62; the carrier 61 includes a carrier 611, a first limit block 612, a second limit block 613, a first spring 614, a second spring 615, a drive block 616 and a second telescopic cylinder 617; the top of the carrier 611 has a limit bottom surface 6111, a first vertical limit surface 6112 and a second vertical limit surface 6113 that are perpendicular to each other; the first limit block 612 has a third vertical limit surface 6123 corresponding to the first vertical limit surface 6112 and a first extension portion 6121 extending perpendicularly to the third vertical limit surface 6123; the second limit block 613 has a fourth vertical limit surface 6132 corresponding to the second vertical limit surface 6113 and a second extension portion 6131 extending perpendicularly to the fourth vertical limit surface 6132; An extension portion 6121 and a second extension portion 6131 are both inserted into the carrier 611 and are both slidably matched with the carrier 611; the first spring 614 is arranged between the first limit block 612 and the carrier 611 and is used to drive the third vertical limit surface 6123 away from the first vertical limit surface 6112; the second spring 615 is arranged between the second limit block 613 and the carrier 611 and is used to drive the fourth vertical limit surface 6132 away from the second vertical limit surface 6113; the second telescopic cylinder 617 is used to drive the driving block 616 to slide, so that the first limit block 612 and the second limit block 613 slide at the same time and overcome the elastic force of the first spring 614 and the second spring 615, and the first vertical limit surface 6112, the second vertical limit surface 6113, the third vertical limit surface 6123 and the fourth vertical limit surface 6132 are combined to form a rectangular limit space for positioning the terminal 100.

[0039] like Figure 5As shown, in the present embodiment, six carriers 61 are provided; initially, under the action of the first spring 614 and the second spring 615, the first limit block 612 and the second limit block 613 are in an open state, that is, the length and width of the rectangular space formed by the first vertical limit surface 6112, the second vertical limit surface 6113, the third vertical limit surface 6123 and the fourth vertical limit surface 6132 are both greater than the length and width of the terminal 100. After the terminal 100 is placed on the limiting bottom surface 6111, the second telescopic cylinder 617 is actuated to drive the first limit block 612 and the second limit block 613 to slide and close at the same time. After closing, the length and width of the rectangular limit space enclosed by the first vertical limit surface 6112, the second vertical limit surface 6113, the third vertical limit surface 6123 and the fourth vertical limit surface 6132 for positioning the terminal 100 are adapted to the length and width of the terminal 100, thereby achieving accurate positioning of the terminal 100. As shown Figure 6 As shown, the first extension portion 6121 and the second extension portion 6131 are rectangular blocks. Obviously, the first extension portion 6121 and the second extension portion 6131 can also be cylinders with non-circular cross-sections.

[0040] In this embodiment, if Figure 6 As shown, the top of the first limit block 612 has a third extension portion 6122 perpendicular to the third vertical limit surface 6123, and the third extension portion 6122 extends from the third vertical limit surface 6123 to the first vertical limit surface 6112; when the first limit block 612 and the second limit block 613 are closed, the third extension portion 6122 covers the terminal 100, thereby preventing the terminal 100 from shaking and causing the position to shift during the movement of the transfer positioning seat 60. Obviously, a fourth extension portion perpendicular to the fourth vertical limit surface 6132 can also be provided on the top of the second limit block 613, and the fourth extension portion extends from the fourth vertical limit surface 6132 to the second vertical limit surface 6113 to achieve the same purpose of the third extension portion 6122. Figure 6 As shown, the third extension portion 6122 is a rectangular block. Obviously, the third limiting block can also be a column block with other cross sections.

[0041] like Figure 5 and 6 As shown, the limiting bottom surface 6111 has a third suction hole 6114, and the side of the carrier 611 is provided with a third connector hole 6115 connected to the third suction hole 6114. The third connector hole 6115 is used to connect an air connector, thereby connecting a vacuum generator or other vacuum generating device through the air connector.

[0042] like Figure 5As shown, in this embodiment, the driving block 616 is slidably arranged on the seat body 62 along a direction perpendicular to the third vertical limit surface 6123, and the driving block 616 has a first driving surface 6161 and a second driving surface 6162 connected to the first driving surface 6161 on the side facing the carrier 611; the first driving surface 6161 and the third vertical limit surface 6123 are located on the same side of the carrier 611; the second driving surface 6162 is a first inclined surface inclined relative to the first driving surface 6161; the second limiting block 613 has a second inclined surface 6133 matching the first inclined surface, so that one driving device can simultaneously drive the first limiting block 612 and the second limiting block 613 to move. Specifically, the piston rod of the second telescopic cylinder 617 extends out, drives the first limiting block 612 to slide through the first driving surface 6161, and then drives the second limiting block 613 to slide at the same time under the action of the first inclined surface and the second inclined surface 6133.

[0043] like Figure 5 As shown, in the present embodiment, the first extension portion 6121 of each first limiting block 612 is arranged in parallel, and each third vertical limiting surface 6123 is located on the same side of the carrier 611; each fourth vertical limiting surface 6132 is located on the same side of the carrier 611, so that all the second telescopic cylinders 617 can be arranged on the same side of the carrier 611, and the air joint connected to the third joint hole 6115 is located on the other side of the carrier 611, which is convenient for arranging the air pipe; and a unified slide 63 can be provided so that all the driving blocks 616 can slide in cooperation with the same slide 63.

[0044] like Figure 7 As shown, in this embodiment, the feeding unit 20 and the pulling unit 30 both include a track 21, a ratchet 22, a first motor 23 driving the ratchet 22 to rotate, and a third telescopic cylinder 24 driving the first motor 23 to rise and fall; the track 21 has a material trough 211 penetrating along the first horizontal direction; the outer circumferential surface of the ratchet 22 has ratchets matching the positioning holes of the material belt; the material trough 211 has an avoidance groove 212 for avoiding the rotation of the ratchets. The material belt is inserted into the material trough 211, and the ratchets of the ratchet 22 are inserted into the positioning holes of the material belt. With the continuous rotation of the first motor 23, the ratchets drive the material belt to move along the first horizontal direction to the positioning hole where the ratchets leave the material belt, and at the same time, the next ratchets are inserted into the next positioning hole of the material belt, so that the material belt always moves along the first horizontal direction. The feeding unit 20 conveys the material belt in the forward cutting mold 10, and the pulling unit 30 pulls the material belt from behind, so that the material belt is always in a straight state, which is less likely to be stuck than setting only the feeding unit 20. When the material belt is replaced, the piston rod of the third telescopic cylinder 24 is extended, and the ratchet is away from the material slot 211 , so that the new material belt can be inserted into the material slot 211 easily.

[0045] like Figure 7As shown, in this embodiment, the bottom surface of the slot 211 has a clearance groove 213 for avoiding the coating of the terminal 100. By providing the clearance groove 213, the bottom surface of the slot 211 is prevented from directly contacting the coating of the terminal 100, so that during the movement of the material belt, the coating of the terminal 100 is suspended in the air, thereby preventing the coating of the terminal 100 from being damaged due to friction.

[0046] like Figure 8 As shown, in this embodiment, the press 13 includes a bottom plate 131, a top plate 132 disposed above the bottom plate 131, four guide pillars 133 penetrating the bottom plate 131 and slidingly cooperating with the bottom plate 131, and a power device disposed below the bottom plate 131; the top ends of the four guide pillars 133 are connected to the bottom plate 131, and the four guide pillars 133 are distributed in a rectangular shape; the power device is used to drive the four guide pillars 133 to rise and fall simultaneously; the die 11 and the punch 12 are both located between the bottom plate 131 and the top plate 132; a cavity 114 is formed between the bottom plate 131 and the die 11. Figure 1 and 8 As shown, two vertical plates 139 are fixed to the bottom of the die 11, and the two vertical plates 139 are arranged at intervals; the opposite surfaces of the two vertical plates 139, the bottom surface of the die 11 and the top surface of the bottom plate 131 form a cavity 114. By providing two vertical plates 139, the die 11 is raised, and the power device is placed under the bottom plate 131, thereby leaving more space for the first linear drive unit 50 and the material receiving unit 40, and the structure is more reasonable.

[0047] The power device can adopt existing technologies such as oil cylinders. In this embodiment, Figure 8 As shown, the power device includes a bracket 134 disposed below the bottom plate 131, a crankshaft 135 rotatably supported on the bracket 134, a second motor 136 driving the crankshaft 135 to rotate, two fourth connecting rods 137 rotatably connected to the crank of the crankshaft 135, and two transfer rods 138 respectively hinged to the two fourth connecting rods 137; the two transfer rods 138 are arranged in parallel and each connects two guide pillars 133. By arranging the crankshaft 135 and the two fourth connecting rods 137 located on the same crankshaft 135, the power is evenly transmitted to the four guide pillars 133, thereby ensuring the cutting accuracy.

[0048] The present utility model is not limited to the above-mentioned optional implementation modes. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all technical solutions that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
