DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0033] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0034] The directional and positional terms used in this invention, such as up, down, front, back, left, right, inside, outside, top, bottom, and side, are merely references to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0035] A bidirectional synchronous pushing mechanism, such as Figure 2 As shown, it includes two groups of pushing components, a connecting rod component, and a driving mechanism 1. The connecting rod component includes an input end and two output ends. The two output ends are respectively connected to the two groups of pushing components. The two output ends move synchronously under the drive of the input end and move in opposite directions to make the two groups of pushing components push toward each other; the driving mechanism 1 is used to drive the input end.

[0036] like Figure 3 As shown, the pushing assembly includes a first track member 2, a first sliding block 3, a pushing block 4, and a push rod 11. The first track member 2 and the first sliding block 3 cooperate so that the first sliding block 3 can only slide along the track direction of the first track member 2. The pushing block 4 is fixed on the first sliding block 3, and the output end performs an arc motion. The fixed connection is provided with a pushing block 4, and a matching groove 401 is provided at the upper end of the pushing block 4. The output end is inserted into the matching groove 401, so that the arc motion of the output end is converted into a linear motion of the pushing block 4. The push rod 11 is connected to the first sliding block 3. When the first sliding block 3 slides back and forth along the track direction of the first track member 2, the push rod 11 performs a push-reset reciprocating action.

[0037] Because the material pushed out in this embodiment is a relatively thin metal conductive pin, a material platform 12 is also provided in conjunction with the pushing assembly. The push rod 11 cooperates with the material platform 12 to push out the material (the relatively thin metal conductive pin) that has landed on the material platform 12, completing the assembly. Specifically, a guide rail 1201 is fixed to the material platform 12. The push rod 11 engages with the guide rail 1201 in a position-limiting manner. The push rod 11 engages with the push block 4. The position of the material platform 12 corresponds to the position of the push block 4, which positions the push rod 11 horizontally, ensuring that the push rod 11 is pushed and reset horizontally.

[0038] like Figure 5As shown, the connecting rod assembly includes a fixed connecting plate 5, and two groups of transmission pairs are connected to the connecting plate 5. One group of transmission pairs includes a transverse swing arm 6 and a longitudinal swing arm 7. One end of the transverse swing arm 6 is hingedly connected to the connecting plate 5 to form a first hinge end, and the other end forms a driving end. One end of the longitudinal swing arm 7 is hingedly connected to the connecting plate 5 to form a second hinge end, and the other end is provided with an output end. A hinge shaft 8 is provided that passes through the first hinge end, the connecting plate 5, and the second hinge end. The hinge shaft 8 forms a linkage with both the transverse swing arm 6 and the longitudinal swing arm 7, and the hinge shaft 8 is rotatable relative to the connecting plate 5.

[0039] The connecting rod assembly includes a push plate 9, the input end is arranged on the push plate 9, the driving ends of the two transverse swing arms 6 are close to each other and are located on one side of the push plate 9, and the push plate 9 is driven to form a thrust in the same direction on the driving ends of the two transverse swing arms 6.

[0040] The drive mechanism 1 includes a rotary motor and an output shaft connected to the rotary motor, with a cam portion 101 provided on the output shaft. A limiting structure is provided to allow the push plate 9 to slide along a straight line. An elastic member acts on the connecting rod assembly to force the input end into contact with the cam portion 101. Specifically, the limiting structure is a guide rail assembly connected to the push plate 9.

[0041] When the rotary motor drives the output shaft to rotate one circle, the cam portion 101 pushes the push plate 9 to slide along a straight line to complete a reciprocating motion, so that the two sets of transmission pairs complete a reciprocating motion at the same time, realizing the synchronous action of the two push components.

[0042] In the figure, the two pusher assemblies are located on either side of the same position. When in operation, the two pusher assemblies move in opposite directions, completing the pushing of the inserted parts from both sides. The two pusher assemblies can also be arranged in a front-to-back arrangement. According to the actual assembly requirements of the parts and the design requirements of the front-to-back arrangement, the thickness of the connecting plate 5 can be adjusted. Even if the thickness of the two hinged locations of the connecting plate 5 is different, the thickness of the longitudinal swing arm 7 can be different. By adjusting the thickness of the output end of the longitudinal swing arm 7, even if the two pusher assemblies are arranged in a front-to-back arrangement, the thickness of the output end of the longitudinal swing arm 7 can be lengthened to meet the matching relationship with the pusher assemblies.

[0043] The input end is a first roller 901 rotatably connected to the push plate 9 .

[0044] The elastic member is a tension spring 10, and the tension spring 10 is connected to the transverse swing arm 6. The other end of the tension spring 10 is fixed on the frame.

[0045] The articulated shaft 8 and the transverse swing arm 6 as well as the articulated shaft 8 and the longitudinal swing arm 7 are connected via a fastening assembly 13;

[0046] like Figure 6 、 Figure 7As shown, the fastening assembly 13 includes a first clamping ring 1301 having an axial notch and a second clamping ring 1302 having an axial notch. The outer circumference of the first clamping ring 1301 is a conical surface, and the inner circumference of the second clamping ring 1302 is a conical surface. The tapers of the outer circumference of the first clamping ring 1301 and the inner circumference of the second clamping ring 1302 are adapted so that the second clamping ring 1302 is sleeved outside the first clamping ring 1301 and the two fit together.

[0047] One end of the first clamping ring 1301 is convexly formed into a connecting ring 1303. The connecting ring 1303 is provided with a plurality of first connecting holes. The second clamping ring 1302 is correspondingly provided with a plurality of second connecting holes 1305. The second connecting holes 1305 are threaded holes and are provided with bolts 1304. The bolts 1304 pass through the first connecting holes and threadably engage with the second connecting holes 1305. The first and second clamping rings 1301, 1302 have axial cutouts, allowing them to be opened or tightened. The bolts 1304 are used to adjust the relative positions of the first and second clamping rings 1301, 1302. Through the interaction of the two conical surfaces, tightening the bolts 1304 tightens the first clamping ring 1301 to form a tight fit with the hinge shaft 7, while opening the second clamping ring 1302 to form a tight fit with the hole wall of the transverse swing arm 6 or the longitudinal swing arm 7.

[0048] The output end is a second roller 701 rotatably connected to the longitudinal swing arm 7, and the matching groove 401 is a U-shaped groove to reduce friction resistance.

[0049] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
