[0035] In this embodiment, a lower spring mechanism is provided along the feeding direction of the spring feeding channel 212, which is used to insert the spring part of the spring feeding channel 212 into the base part; a pressure rod insertion mechanism 5 is provided along the feeding direction of the pressure rod feeding channel 222, which is used to insert the pressure rod part on the pressure rod feeding channel 222 into the base part.

[0036] Since the pressure rod member itself is in the shape of a long strip, the pressure rod member is in a flat state when loading. In this embodiment, the pressure rod member in the flat state is adjusted to a vertical state and then inserted into the base member.

[0037] In the description of this embodiment, a pressure rod reversing mechanism 4 is provided in the feeding direction of the pressure rod feeding channel 222, which is used to adjust the pressure rod from a horizontal state to a vertical state. Specifically, the pressure rod reversing mechanism 4 includes a turntable 41, and the turntable 41 is provided with a material receiving slot hole 42 along its circumference, and the turntable 41 is connected to a turntable driving member 43 that drives it to rotate.

In this embodiment, the insert spring assembly machine is provided with a base positioning mechanism 6 along the feeding direction of the base feeding channel 232, and the base positioning mechanism 6 is used to position the base to be assembled to prevent the base member from being offset during assembly.

[0042] Specifically, the base positioning mechanism 6 includes a clamping drive member 61 and a clamping arm 62. The clamping drive member 61 can drive the clamping arm 62 to open or close. When the base member needs to be clamped, the clamping drive member 61 drives the clamping arm 62 to clamp the base member. The clamping drive member 61 can be optionally but not limited to a cylinder.

[0043] Specifically, the driving end of the clamping driving member 61 is connected to a reversing slide 63, and the reversing slide 63 is provided with an inclined hole 64. One end of the clamping arm 62 is connected to a cam 65, and the cam 65 is arranged in the inclined hole 64. The inclination angle of the inclined hole 64 forms an angle with the driving direction of the clamping driving member 61. When the reversing slide 63 of the clamping driving member 61 reciprocates, the cam 65 is driven to move toward or away from each other, thereby driving the clamping arm 62 to open or close.

[0044] Specifically, in order to ensure the clamping accuracy of the clamping arm 62 on the base member, the clamping arm 62 is connected to a slide rail 66, and the clamping arm 62 is slidably arranged on the slide rail 66 to ensure that the movement trajectory of the clamping arm 62 will not be offset. A clamping portion 67 is provided on the side of the clamping arm 62 away from the cam 65, and a clamping groove 68 matching the base member is provided on the clamping portion 67 to ensure the clamping accuracy of the clamping arm 62 on the base member.

[0045] In the further description of this embodiment, the pressure rod insertion mechanism 5 includes a pressure rod insertion driving member 51, a driving end of the pressure rod insertion driving member 51 is connected to a pressure rod clamp, and the pressure rod clamp is connected to a clamp driving member. The pressure rod insertion driving member 51 drives the pressure rod clamp to perform an insertion action, and the clamp driving member drives the pressure rod clamp to grab the pressure rod member of the pressure rod feeding channel 222.

[0046] Specifically, the pressure rod driving member 51 drives the pressure rod clamping claw to reach the pressure rod member of the pressure rod feeding channel 222, and the clamp driving member pressure rod clamping claw grabs the pressure rod member of the pressure rod feeding channel 222, and the pressure rod driving member 51 drives the pressure rod clamping claw to insert the grabbed pressure rod member into the base member. The pressure rod driving member 51 can be selected from but not limited to a cylinder, and the pressure rod clamping claw can be selected from but not limited to a cylinder.

[0047] In one embodiment, a pressure rod sensor 8 is provided along the feeding direction of the pressure rod feeding channel 222, and the pressure rod sensor 8 is provided on one side of the turntable 41 and faces the turntable 41.

[0048] In one embodiment, the insert spring assembly machine further includes a feeding mechanism 9, which includes a good product detection member 91 and a feeding channel 92. The good product detection member 91 is connected to a separation drive member 93, and the separation drive member 93 is used to separate defective products. Specifically, the good product detection member 91 detects the assembled product parts, and discharges the product from the feeding channel 92 after the detection is qualified. If the detection is unqualified, the separation drive member 93 separates the defective products. The separation drive member 93 can be selected from but not limited to a cylinder.

[0049] Embodiment 3:

[0050] This embodiment provides a leaf spring assembly machine, which is further optimized on the basis of Embodiment 1 and Embodiment 2.

[0051] In order to realize the coordinated operation of the insertion and pressure rod mechanism 5 and the lower spring mechanism, in this embodiment, the insertion and pressure rod mechanism 5 is connected to an assembly switching driving member 7 that drives it to reciprocate between the base positioning mechanism 6 and the pressure rod reversing mechanism 4 .

[0052] Specifically, the lower spring mechanism includes a lower spring driver 31, which is fixedly connected to the insertion and pressure rod mechanism 5 through a fixing plate 71. When the assembly switching driver 7 drives the insertion and pressure rod mechanism 5 to reciprocate between the base positioning mechanism 6 and the pressure rod reversing mechanism 4, it also drives the lower spring mechanism to reciprocate between the spring feeding channel 212 and the base positioning mechanism 6. The spring driver may be, but is not limited to, a cylinder, and the assembly switching driver 7 may be, but is not limited to, a cylinder.

[0053] Specifically, the driving end of the lower spring driving member 31 grabs the spring member from the spring feeding channel 212. Preferably, the driving end of the lower spring driving member 31 can be connected to the clamping claw. After the driving end of the lower spring driving member 31 grabs the spring member, the assembly switching driving member 7 drives the lower spring driving member 31 to move the grabbed spring member to the corresponding position of the base positioning mechanism 6. The lower spring driving member 31 puts the grabbed spring member into the base member locked by its corresponding base positioning mechanism 6; after the assembly switching driving member 7 drives the lower spring driving member 31 to move the grabbed spring member to the corresponding position of the base positioning mechanism 6 At the same time, the assembly switching drive member 7 synchronously drives the insertion pressure rod drive member 51 to the pressure rod reversing mechanism 4. While the driving end of the lower spring drive member 31 grabs the spring member, the insertion pressure rod drive member 51 drives the pressure rod clamp to clamp the vertical pressure rod member at the pressure rod reversing mechanism 4; when the assembly switching drive member 7 continues to drive the lower spring drive member 31 back to the position of the spring feeding channel 212, it drives the insertion pressure rod drive member 51 to the corresponding position of the base positioning mechanism 6. When the spring drive member grabs the next spring member, the insertion pressure rod drive member 51 drives the pressure rod clamp to insert the clamped pressure rod member into the base member; and this reciprocating cycle is repeated.
