[0002] Circuit board insertion refers to the process of inserting electronic devices onto circuit boards. The speed and accuracy of insertion will seriously affect the efficiency and quality of circuit board assembly. Existing insertion equipment generally uses cylinder drive for lifting and displacement, which has slow speed, low accuracy, and high noise, and can no longer meet production needs. Utility Model Content

[0003] In order to solve the above problems, the utility model provides an electric base lifting device, which can perform reciprocating lifting more accurately and quickly, and can also effectively reduce noise pollution and use costs.

[0004] The technical solution adopted by the utility model is to provide an electric base lifting device, including a driving motor, a screw rod connected to the driving motor in transmission, a lifting seat sleeved on the screw rod, a guide slide rail arranged at intervals on one side of the lifting seat, a slider arranged on the guide slide rail for upward and downward sliding and fixed to one side of the lifting seat, a connecting rod fixed to the other side of the lifting seat, and a mounting seat connected to the connecting rod, the screw rod and the guide slide rail are both arranged vertically, the screw rod rotates to drive the lifting seat and the slider to rise and fall synchronously, and the lifting seat drives the mounting seat to rise and fall synchronously through the connecting rod.

[0005] It also includes a connecting bearing arranged on a connecting rod and an annular groove arranged on the outer periphery of a mounting seat. The connecting rod is arranged transversely, and the connecting bearing is sleeved on the outer end of the connecting rod and embedded in the annular groove.

[0006] It also includes a first pulley arranged on the driving end of the driving motor, a second pulley arranged at the lower end of the screw and located at the same horizontal position as the first pulley, and a transmission belt arranged on the first pulley and the second pulley. The driving motor drives the first pulley to rotate and drives the second pulley to rotate with the help of the transmission belt. The rotation of the second pulley drives the screw to rotate synchronously.

[0007] The beneficial effect of the utility model is that it provides an electric base lifting device, which adopts a driving motor instead of a cylinder as a drive, and can lift and lower more accurately and quickly during insertion, thereby improving efficiency, reducing noise pollution, reducing use costs, and making the lifting process smoother.

Specific embodiments

[0012] As Figures 1 - 3 shown, the present utility model provides an electric base lifting device, which includes a driving motor 1, a lead screw 2 drivingly connected to the driving motor 1, a lifting seat 3 sleeved on the lead screw 2, a guiding slide rail 4 arranged at an interval on one side of the lifting seat 3, a slider 5 slidably arranged up and down on the guiding slide rail 4 and fixed to one side of the lifting seat 3, a connecting rod 6 fixed to the other side of the lifting seat 3, and a mounting seat 7 connected to the connecting rod 6. The lead screw 2 and the guiding slide rail 4 are both vertically arranged. The rotation of the lead screw 2 drives the lifting seat 3 and the slider 5 to lift synchronously, and the lifting seat 3 drives the mounting seat 7 to lift synchronously through the connecting rod 6.

[0013] This design uses the driving motor 1 as the drive, replacing the traditional cylinder drive. The driving motor 1 drives the lead screw 2 to rotate. The outer circumference of the lead screw 2 has an external thread, and the lifting seat 3 has a matching threaded hole. The rotation of the lead screw 2 drives the lifting seat 3 to perform a lifting movement on the lead screw 2. The guiding slide rail 4 is fixedly installed on one side of the lifting seat 3 and is parallel to the lead screw 2. The slider 5 slidably installed on the guiding slide rail 4 is fixed to the lifting seat 3. When the lifting seat 3 lifts, the slider 5 on the guiding slide rail 4 lifts synchronously to guide the lifting seat 3 so that the lifting seat 3 will not rotate on its own and can lift stably. The connecting rod 6 fixed to the other side of the lifting seat 3 is also fixed to the mounting seat 7. When the lifting seat 3 lifts, it drives the mounting seat 7 to lift synchronously. The mounting seat 7 is used to install a plug-in component, and the plug-in component is a component for clamping and placing components. Without changing the plug-in component, this design uses the driving motor 1 to drive. Utilizing the high-speed and precise performance of the driving motor 1, the plug-in component can be lifted quickly to complete the plugging action, greatly improving the plugging speed and accuracy.

[0014] As Figures 1 - 3 shown, it further includes a connecting bearing 8 arranged on the connecting rod 6 and an annular groove 9 arranged on the outer circumference of the mounting seat 7. The connecting rod 6 is horizontally arranged, and the connecting bearing 8 is sleeved on the outer end of the connecting rod 6 and embedded in the annular groove 9.

[0015] The mounting base 7 is a vertical columnar structure, with a ring groove 9 added to its outer periphery. A connecting bearing 8 is installed at one end of the connecting rod 6 facing the mounting base 7, and the connecting bearing 8 is embedded in the ring groove 9. This can, without affecting the lifting of the mounting base 7, also not affect the rotation of the mounting base 8, making it more flexible in use, with a wider range of applications, and enabling further expansion of more functions.

[0016] As Figures 1 - 3 shown, it also includes a first pulley 10 arranged on the driving end of the driving motor 1, a second pulley 11 arranged at the lower end of the lead screw 2 and at the same horizontal position as the first pulley 10, and a transmission belt 12 arranged on the first pulley 10 and the second pulley 11. The driving motor 1 drives the first pulley 10 to rotate and drives the second pulley 11 to rotate by means of the transmission belt 12. The rotation of the second pulley 11 drives the lead screw 2 to rotate synchronously.

[0017] Transmission is carried out through the first pulley 10, the second pulley 11, and the transmission belt 12. The transmission is stable and the assembly is convenient. The second pulley 11 is fixed at the lower end of the lead screw 2, which does not interfere with the lifting of the lifting seat 3, the mounting base 7, and the slider 5, while making its assembly space larger and the assembly more convenient.
