[0023] Example 1

[0024] Reference Figure 1-5 The schematic diagram shows the overall structure of the screwing device proposed in this embodiment. At present, in the production process, when the thermos cup lid is tightened, the position of the logo of the cup lid and the position of the cup handle have a relative angle requirement, and the position of the handle is determined by the connecting piece M on the cup body S, that is, the spot welding piece; the position of the connecting piece M is determined by manually screwing the cup lid, and then marking the cup body S with a paintbrush, and fixing the connecting piece M at the marked position by spot welding. This method has high labor costs and low efficiency. Figure 5 As shown in the figure, a positioning fixture 200 and a positioning block 201 are proposed, which can position the cup body S at the marking position, and the screwing device of this embodiment is used to assist the rotation of the cup body S, thereby realizing the tightening, positioning and loosening of the cup body S on the positioning fixture 200.

[0025] For ease of understanding, the positioning and marking process of the thermos cup is described as follows: Referring to the existing mature technology, the positioning and marking automated production line for the cup body and handle includes a loading position, a tightening position, a marking position, a loosening position and a unloading position, wherein the tightening position and the loosening position are realized by relying on the screwing device proposed in this embodiment, and assist the positioning of the positioning fixture 200 and the cup body S, that is, the up and down displacement, tightening and loosening actions. The screwing assembly 100 tightens the cup body S to the positioning fixture 200. When the cup body S is rotated into place, the positioning is completed, that is, the cup body S reaches the angle required by the position of the cup cover logo and the position of the cup body handle. At this time, the laser polisher marks the automatically aligned cup body S. After the position marking is completed, the screwing assembly 100 is rotated in the opposite direction again. After the cup body S is separated from the positioning fixture 200, the cup body S is taken out by the discharging equipment to complete the positioning, marking and marking operation. It should be noted that for the automated marking production line for thermos cups, other automated parts can be implemented with reference to current technologies, such as loading and unloading. At the same time, the positioning fixture 200 can also be achieved by manually screwing the cup lid and then marking the cup body S with a brush. The core essence of this embodiment is not how the positioning fixture 200 is positioned, but only to achieve the up and down displacement, tightening and loosening actions between the positioning fixture 200 and the cup body S.

[0026] Refer again Figure 1-4As shown in the figure, this embodiment proposes a screwing assembly 100 of a screwing device, which is used to tighten the cup body S. Specifically, the screwing assembly 100 includes a clamping mechanism 101, a lifting mechanism 102 and a rotating mechanism 103; wherein the rotating mechanism 103 is arranged above the clamping mechanism 101, and is used to drive the rotation of the clamping mechanism 101, and the lifting mechanism 102 is arranged on the side of the clamping mechanism 101, and is used to drive the clamping mechanism 101 to move up and down, and the clamping mechanism 101 is used to clamp the cup body S.

[0027] More specifically, the clamping mechanism 101 includes a clamp 101a, a clamp cylinder 101b, a clamp slider 101c, a clamp slot 101d and a pressure block 101e; the clamp slider 101c is arranged above the clamp 101a and slides in the clamp slot 101d, and is the moving track of the clamp 101a, at least three clamps 101a are arranged below the clamp cylinder 101b, the clamp cylinder 101b is used to drive the movement of the clamp 101a, and the pressure block 101e is arranged below the clamp 101a.

[0028] The working process of the clamping mechanism 101 is as follows: the pressing block 101e first contacts the cup body S, and the clamping jaw cylinder 101b drives the clamping jaw 101a to open and tighten to clamp the cup body S.

[0029] The rotating mechanism 103 includes a rotating shaft 103a, a limiting pin 103b, a limiting slide 103c, a guide seat 103d and an elastic member 103e. More specifically, the rotating shaft 103a is connected to a drive for rotation and a limiting truncated table 103g is arranged below. The drive is a servo motor 103h, which is a kind of electric motor, commonly used in control systems, and can provide precise control and positioning. The basic principle of operation is to rotate to a specific angle position and maintain the position, and the rotation of the rotating shaft 103a can be precisely controlled. The output shaft of the servo motor 103h is connected to the coupling 103i, and is fixedly arranged on the lifting bracket 102a through the support of the mounting frame 103j. After the servo motor 103h is connected to the coupling 103i, it is connected to the bearing 103k, and a slip ring 103f is arranged below to realize the rotation of the rotating shaft 103a driven by the servo motor 103h.

[0030] Furthermore, the limiting pin 103b is arranged on one side of the limiting truncated cone 103g, and the limiting slot 103c is arranged on the guide seat 103d. After the rotating shaft 103a is inserted into the guide seat 103d, it can only move up and down through the cooperation and limiting action of the limiting pin 103b and the limiting slot 103c. The elastic member 103e is arranged in the guide seat 103d, and the upper and lower parts thereof conflict with the limiting truncated cone 103g and the clamping mechanism 101 respectively. The rotation of the rotating shaft 103a drives the rotation of the guide seat 103d, and the guide seat 103d is fixedly connected with the clamping mechanism 101. It should be noted that the guide seat 103d and the clamping mechanism 101 of this embodiment are fixedly arranged, that is, the guide seat 103d and the clamping mechanism 101 cannot rotate relative to each other, and specifically, the bottom of the guide seat 103d is fixed to the upper part of the clamping jaw cylinder 101b through a flange.

[0031] The working process of the rotating mechanism 103 is as follows: the servo motor 103h is started, and the rotating shaft 103a is driven to rotate through the transmission of the coupling 103i and the bearing 103k. Due to the limiting effect of the limiting pin 103b, the guide seat 103d rotates with the rotation of the rotating shaft 103a, thereby driving the clamping mechanism 101 to rotate. When the clamping mechanism 101 clamps the cup body S, it drives the cup body S to rotate.

[0032] Furthermore, the present embodiment further comprises a lifting mechanism 102, which is connected to the rotating mechanism 103 via a lifting bracket 102a, and specifically, comprises a lifting bracket 102a, a fixed bracket 102b, a slide rail 102c, a limit top block 102d, a limit seat 102e and a limit rod 102f; wherein the lifting bracket 102a is connected to the fixed bracket 102b by sliding up and down via the slide rail 102c, the limit top block 102d is arranged below the lifting bracket 102a, the limit seat 102e is fixed on the fixed bracket 102b, the limit top block 102d is connected to the limit rod 102f, and the limit top block 102d is inserted into the limit seat 102e through the limit rod 102f and moves up and down until the limit top block 102d conflicts with the limit seat 102e. In the present embodiment, the lifting bracket 102a is connected to the lifting cylinder 102h via a connecting rod 102g.

[0033] The working process of the lifting mechanism 102 is as follows: the lifting cylinder 102h outputs power to the connecting rod 102g, and the connecting rod 102g drives the lifting bracket 102a to move up and down, and stops when the limit top block 102d conflicts with the limit seat 102e. The limit seat 102e is the maximum stroke of downward movement. At the same time, the lifting cylinder 102h can make the limit top block 102d located at any position in the stroke according to the power output.

[0034] According to the scheme of the above embodiment, after the positioning of the cup body S is completed, it is rotated to the marking position for marking. The marking equipment in this embodiment is a laser marking machine, which uses a laser beam to mark the surface of various materials permanently. The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks, text, etc. In this embodiment, it is the mark of the handle position for the subsequent precise welding of the handle. The cup body S is positioned to the set angle by rotating the screw assembly 100, and is rotated to the marking position through the automated workbench to complete the marking and marking. After the marking is completed, it enters the loosening position to loosen the cup body S, and finally enters the unloading position to remove the marked cup body S. At this point, the positioning, marking and marking of the entire cup body S are completed. The automated control part involved in this embodiment is not a necessary technical feature, and it can be fully implemented with reference to existing mature technologies, so it will not be described in detail.
