[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model embodiment discloses a device for synchronously adjusting the spacing and angle of an injection pen, which includes two parallel bearing fixing seats 8, a central axis 10 arranged on the two bearing fixing seats 8, two connecting plates 11 parallel to each other and respectively arranged at both ends of the central axis 10, two sliding shafts 12 parallel to each other and arranged between the two connecting plates 11, a carrier assembly 16 arranged on the sliding shaft 12, a driving assembly capable of driving the central axis 10 to rotate relative to the bearing fixing seats 8, and an arc plate 15 capable of limiting the moving trajectory of the carrier assembly 16, and the bearing fixing seats 8 and the central axis 10 are connected with a first bearing 9.

[0026] The carrier assembly 16 includes a connecting block 19 sleeved on two sliding shafts 12, a connecting rod 21 arranged on the connecting block 19, a base 22 arranged on the connecting rod 21, a clamping claw cylinder 23 arranged on the base 22, a clamp 24 arranged on the base 22, and an injection pen 25 arranged on the base 22, the connecting rod 21 passes through the arc plate 15, the connecting block 19 is provided with a sliding sleeve 17 for sleeved on the sliding shaft 12, the connecting block 19 is provided with a shaft sleeve 18 for sleeved on the connecting rod 21, and a composite bearing 20 is provided between the connecting rod 21 and the arc plate 15. The carrier assembly 16 is provided in plurality, and the arc plate 15 is provided with a track groove having a specific angle corresponding to the carrier assembly 16 and for the carrier assembly 16 to pass through.

[0027] A giant synchronous wheel 14 is provided on the central shaft 10, and the driving assembly includes a motor base plate 1 and a servo motor 2, a synchronous belt 7 for transmission connection between the servo motor 2 and the giant synchronous wheel 14, a bearing seat 5 provided on the motor base plate 1, and a second bearing 4 provided on the bearing seat 5, a reducer 3 provided at the output end of the servo motor 2, and a synchronous wheel 6 provided at the output end of the reducer 3, the synchronous wheel 6 is transmission-connected to the giant synchronous wheel 14 through the synchronous belt 7, and the synchronous wheel 6 is connected to the second bearing 4.

[0028] The arc plate 15 in the utility model adopts a 90° rotating arc path. The device combines a rotating mechanism and a variable pitch mechanism, allowing fast and accurate transfer of parts in a limited space.

[0029] The carrier assembly 16 is used to install and fix the injection pen 25. Under the joint action of the base 22, the clamp cylinder 23 and the clamp 24, the injection pen 25 can be stably placed in the clamp 24 to facilitate the connection between the previous and next processes, and change the injection pen 25 from the horizontal direction to the vertical direction while changing the spacing; the sliding sleeve 17 is provided with two channels for the sliding shaft 12 to move back and forth, and the two sliding shafts 12 are arranged in parallel. The matching design of the sliding shaft 12 and the sliding sleeve 17 fully ensures the smooth operation of the carrier assembly 16 during the process of flipping at a specific angle.

[0030] The power of the servo motor 2 is transmitted to the central shaft 10 through the reducer 3, the synchronous belt 7, etc., and the forward and reverse rotation of the servo motor 2 drives the forward and reverse rotation of the central shaft 10 (wherein, the central shaft 10 is positioned and supported by the first bearing 9, and the bearing fixing seat 8 provides support force for it. Connecting plates 11 are respectively provided at both ends of the central shaft 10, and the sliding shaft 12 is deflected by the connecting plates 11). A groove structure is provided on the arc plate 15. During the forward and reverse rotation of the servo motor 2, the sliding shaft 12 deflects along with the servo motor 2, thereby driving the movement of the carrier assembly 16. At the same time, since the sliding shaft 12 is an optical axis, under the action of the deflection force of the sliding shaft 12 and the guiding action of the groove structure of the arc plate 15, the forward and reverse motion of the servo motor 2 is converted into a cyclic reciprocating conversion of a specific distance and a specific angle of the carrier assembly 16.

[0031] The utility model proposes a device for synchronously adjusting the spacing and angle of injection pens 25, which mainly includes a 90° rotating pitch-changing mechanism, a clamping cylinder 23, a servo motor 2, a composite bearing 20 and other components. The injection pens 25 on the material tray are grabbed by a spider hand robot and placed on the 90° rotating pitch-changing mechanism. After the clamping cylinder 23 clamps the injection pen 25, the servo motor 2 drives the central shaft 10 to rotate, so that the carrier assembly 16 rotates. At the same time, the composite bearing 20 rolls in the inner groove, so that the spacing and angle between each injection pen 25 change simultaneously. This process simplifies the operation steps and improves the adjustment accuracy and production efficiency by synchronously adjusting the spacing and angle of the injection pens 25.

[0032] The implementation principle of the utility model is as follows: First, the spider hand robot grabs the injection pen 25 on the material tray and places it on the carrier assembly 16 of the 90° rotating pitch change mechanism. Then, the clamping cylinder 23 clamps the injection pen 25, and the servo motor 2 starts to work to drive the central shaft 10 to rotate. During the rotation process, the composite bearing 20 rolls in the inner groove, so that the spacing and angle between the injection pens 25 change simultaneously. When the preset spacing and angle are reached (such as Figure 3The product shown is erected), the motor stops working, the gripper cylinder 23 releases the injection pen 25, and the spider hand robot grabs the adjusted injection pen 25 and places it in the next process. During the whole process, the rotation angle and speed of the motor and the rolling trajectory of the composite bearing 20 are accurately controlled by the control system, so as to ensure the adjustment accuracy of the spacing and angle of the injection pen 25. Through the above implementation, the utility model realizes the synchronous adjustment of the spacing and angle of the injection pen 25, and improves the production efficiency and product quality. At the same time, this implementation also has the advantages of simple operation and good stability, and is suitable for the spacing and angle adjustment of the injection pen 25 in a large-scale production environment.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
