[0033] Please refer to Figure 1 The embodiment provides a cap assembly device 100, which comprises a feeding assembly 110, a pre-assembly assembly 120, a cap tightening assembly 130 and a carrier 140, as shown in Figure 4 The carrier 140 is used for placing a plurality of to-be-assembled parts 200 arranged side by side at intervals; the feeding assembly 110 comprises a conveying groove, the conveying groove has a feeding position and a taking position, and the cap can be moved from the feeding position to the taking position; the pre-assembly assembly 120 is arranged on one side of the taking position of the feeding assembly 110, and the pre-assembly assembly 120 comprises a taking part 121, which can clamp and place the cap at the taking position on the mounting position of the to-be-assembled part 200; the cap tightening assembly 130 comprises a tightening part 131, the carrier 140 can drive the to-be-assembled part 200 and the cap to move to the relative position of the tightening part 131, and the tightening part 131 can drive the cap to rotate relative to the to-be-assembled part 200, so that the cap and the to-be-assembled part 200 are fixedly connected.

[0034] Specifically, as shown in Figure 1 The cap assembly device 100 mainly comprises the feeding assembly 110, the pre-assembly assembly 120, the cap tightening assembly 130 and the carrier 140. The carrier 140 plays a role of carrying and transporting the to-be-assembled part 200 and cooperating with various assemblies during assembly, and the to-be-assembled parts 200 are arranged side by side at intervals on the carrier 140. This arrangement mode is beneficial to accurate and independent processing of each to-be-assembled part 200 during assembly, and avoids mutual interference.

[0035] The cap can be moved from the feeding position to the taking position of the conveying groove, and the taking part 121 of the pre-assembly assembly 120 can clamp and place the cap at the taking position on the mounting position of the to-be-assembled part 200, so that the pre-assembly of the cap and the to-be-assembled part 200 is completed. As shown in Figure 1 And Figure 2As shown, the position layout of the pre-assembly assembly 120 is next to the taking position of the feeding assembly 110, and such arrangement can minimize the stroke of the taking part 121 when clamping the cap, thereby improving the assembly efficiency. The taking part 121 can rotate relative to the feeding assembly 110 and the carrier 140, so as to facilitate the transfer of the cap on the feeding assembly 110 to the to-be-assembled part 200 on the carrier 140. Through the arrangement of the pre-assembly assembly 120, the cap can be accurately placed on the mounting position of the to-be-assembled part 200, so as to ensure the accuracy of the preliminary docking of the cap and the to-be-assembled part 200, provide a good basis for subsequent tightening and fixation, and avoid the unqualified final assembly quality due to pre-assembly deviation.

[0036] When the cap is pre-assembled to the to-be-assembled part 200, the carrier 140 can move the to-be-assembled part 200 with the cap to a position corresponding to the tightening part 131, at which time the tightening part 131 starts to work to rotate the cap relative to the to-be-assembled part 200. During the rotation, the cap is gradually tightened on the to-be-assembled part 200 by relying on the cooperation mode of the thread connection between the cap and the to-be-assembled part 200, thereby realizing the firm fixed connection therebetween.

[0037] It should be noted that, in an embodiment of the present application, first, as shown in Figure 3 The number of the tightening parts 131 is multiple, the multiple tightening parts 131 are arranged side by side and spaced from each other, so as to correspond to the multiple to-be-assembled parts 200 of the carrier 140. The tightening part 131 comprises a body 1311, and the body 1311 has a clamping opening 1311a at one end facing the carrier 140. The cap tightening assembly 130 further comprises a rotating motor, which can drive the tightening part 131 to drive the cap to rotate relative to the to-be-assembled part 200 along the axial direction through the clamping opening 1311a.

[0038] Specifically, in order to improve the assembly efficiency, multiple tightening parts 131 are adopted in the present application. These tightening parts 131 are arranged side by side and spaced from each other, so as to correspond to the arrangement form of the multiple to-be-assembled parts 200 on the carrier 140. When the carrier 140 moves the to-be-assembled part 200 with the cap to the specified position, these side-by-side and spaced tightening parts 131 can simultaneously operate on the respective corresponding to-be-assembled part 200 and cap, thereby greatly saving the assembly time, improving the overall production efficiency, and also ensuring the consistency and accuracy of each assembly link, because each tightening part 131 can independently and accurately act on the corresponding part combination.

[0039] As shown in Figure 5As shown, the tightening member 131 comprises a body 1311, and the body 1311 is provided with a clamping opening 1311a at one end thereof, which can stably clamp the cap during subsequent assembly process. Under the driving of the rotary motor, the tightening member 131 rotates around its own axial center, and then drives the clamped cap to rotate axially relative to the to-be-assembled part 200, so that the cap gradually rotates into the threads of the to-be-assembled part 200 until a specified tightening torque is reached, thereby realizing the tight and firm fixed connection between the cap and the to-be-assembled part 200, and ensuring the quality and stability of the entire assembled product.

[0040] Secondly, the number of the transmission grooves is multiple, and the multiple transmission grooves are arranged side by side and spaced from each other; the feeding assembly 110 further comprises a vibration source, which can drive the transmission grooves to vibrate, so that the multiple caps are sequentially moved along the transmission grooves from the feeding position to the taking position.

[0041] Specifically, in order to improve the supply efficiency of the cap, multiple transmission grooves are arranged, so that the multiple caps are sequentially moved along the transmission grooves from the feeding position to the taking position. Since the multiple transmission grooves are arranged side by side, the multiple caps can be arranged in a spaced and side-by-side manner at the end of the feeding assembly 110, so that the taking part 121 can simultaneously place multiple caps on the to-be-assembled part 200, further improving the assembly efficiency.

[0042] The cap assembly device 100 provided by the present application comprises a feeding assembly 110, a pre-assembly assembly 120, a cap tightening assembly 130, and a carrier 140, the carrier 140 is used for placing multiple to-be-assembled parts 200 arranged side by side and spaced from each other, thereby improving the efficiency of the overall assembly; the feeding assembly 110 comprises a transmission groove, the transmission groove has a feeding position and a taking position, and the cap can be moved from the feeding position to the taking position; the pre-assembly assembly 120 is arranged on one side of the taking position of the feeding assembly 110, and the pre-assembly assembly 120 comprises a taking part 121, which can clamp and place the cap at the taking position on the mounting position of the to-be-assembled part 200; the taking part 121 can accurately clamp and place the cap on the mounting position of the to-be-assembled part 200, thereby ensuring the positional accuracy of the cap and the to-be-assembled part 200 in the preliminary assembly stage; the cap tightening assembly 130 comprises a tightening member 131, the carrier 140 can drive the to-be-assembled part 200 and the cap to move to the relative position of the tightening member 131, and the tightening member 131 can drive the cap to rotate relative to the to-be-assembled part 200, so as to realize the fixed connection between the cap and the to-be-assembled part 200. Such a setting mode reduces the additional transfer mechanism, the tightening member 131 realizes the fixed connection between the cap and the to-be-assembled part 200 through rotation, which can ensure the fastening and reliability of the connection, improve the assembly efficiency, and is suitable for large-scale production requirements. The above-mentioned cap assembly device 100 can improve the assembly efficiency and the assembly yield, thereby improving the production efficiency and the product yield.

[0043] In an implementation of the present application, as shown in Figure 3 The cap tightening assembly 130 further comprises a first linear motor 132, which is drivingly connected with the tightening member 131. The first linear motor 132 can drive the tightening member 131 to move the cap relative to the to-be-assembled part 200 along the vertical direction to approach or move away from the to-be-assembled part 200.

[0044] Specifically, as shown in Figure 3 In the cap tightening assembly 130, in addition to the tightening member 131 and the rotating motor, the first linear motor 132 is additionally provided. When the first linear motor 132 receives a control signal to start running, it can move the cap along the vertical direction through the tightening member 131 to approach or move away from the to-be-assembled part 200, so as to adjust the relative distance between the cap and the to-be-assembled part 200, and improve the assembly precision. Meanwhile, when the tightening member 131 drives the cap to rotate, the first linear motor 132 can drive the cap to move downward along the vertical direction through the tightening member 131, so as to press the cap and the to-be-assembled part 200 tightly, and further improve the assembly efficiency.

[0045] For example, as shown in Figure 5 The tightening member 131 further comprises a shell 1312 and an elastic member 1313. The elastic member 1313 is sleeved on the outer wall of the tightening member 131, and the shell 1312 is sleeved on the outside of the body 1311 and the elastic member 1313. The clamping opening 1311a of the body 1311 is exposed by the shell 1312.

[0046] The shell 1312 mainly plays a role of protecting and supporting the internal components, and the elastic member 1313 provides buffering and self-adapting capability for the tightening member 131 during contact and operation with the cap and the to-be-assembled part 200, so as to avoid damage to the cap or the to-be-assembled part 200 due to excessive rotation force.

[0047] Optionally, the cap tightening assembly 130 further comprises a controller and a force sensor. The controller is connected with the force sensor and the rotating motor respectively, and the force sensor is connected with the tightening member 131. When the rotating motor drives the tightening member 131 to rotate, the force sensor can measure the force value in real time, convert the force value into a force signal, and transmit the force signal to the controller. When the force value reaches a preset force value, the controller can drive the tightening member 131 to stop rotating through the rotating motor.

[0048] Specifically, the force sensor can accurately measure the force during the tightening process, and the controller is used for coordinated control and data processing of the force sensor. The force sensor is connected with the tightening member 131 and can directly sense the change of the force received by the tightening member 131 during work. Then, it converts the force information into corresponding force signals and transmits them to the controller. At the same time, the controller is connected with the rotary motor, which enables the controller to accurately control the rotary motor according to the force signals from the force sensor, so as to realize real-time control of the rotating action of the tightening member 131 and ensure the automatic and intelligent operation of the whole system.

[0049] When the rotary motor starts to work and drives the tightening member 131 to rotate to tighten the cap, the force sensor can accurately measure the force received by the tightening member 131 during the tightening process. Subsequently, the force sensor rapidly converts the measured force values into force signals that can be recognized and processed by the controller, and timely transmits them to the controller, providing real-time and accurate data basis for the decision of the controller.

[0050] Before the whole tightening operation starts, the operator will set a suitable target force value in the controller according to the connection requirements of the cap and the to-be-assembled part 200, material properties, and product quality standards and other factors. During the tightening process, the controller will continuously receive the force signals from the force sensor and compare the corresponding force values with the preset force value. Once the measured force value reaches the preset force value, the controller will immediately issue an instruction to the rotary motor to stop the operation, so that the tightening member 131 stops rotating. In this way, it can be ensured that each cap is tightened to the right degree, neither too loose due to insufficient tightening force, affecting product quality and use safety, nor damaged due to excessive tightening force, damaging the cap, the to-be-assembled part 200 or the connecting structure such as the thread, ensuring the consistency and reliability of the product and improving the quality control level of the whole cap assembly process.

[0051] In an embodiment of the present application, as shown in Figure 6 and Figure 7 The cap tightening assembly 130 further includes a positioning portion 133, which is arranged opposite to the tightening member 131, and the carrier 140 can be arranged between the positioning portion 133 and the tightening member 131. The positioning portion 133 includes a plurality of clamping positioning members 1332 arranged side by side and spaced from each other, which are arranged corresponding to the plurality of to-be-assembled parts 200 arranged on the carrier 140, for clamping and fixing the to-be-assembled parts 200.

[0052] Specifically, in order to provide a stable positioning reference for the to-be-assembled part 200, as shown in Figure 6As shown, the cap tightening assembly 130 further comprises a positioning portion 133, which comprises a plurality of positioning plates 1331 arranged side by side and spaced apart from each other, and each of the positioning plates 1331 is provided with a clamping positioning piece 1332 on the side facing the carrier 140. When the carrier 140 transports the to-be-assembled part 200 to the position corresponding to the tightening piece 131, each clamping positioning piece 1332 can accurately contact and firmly clamp the corresponding to-be-assembled part 200, and through the appropriate clamping force, the to-be-assembled part 200 is stably positioned at a specific position, preventing the to-be-assembled part 200 from shifting, rotating or vibrating due to factors such as rotational force and friction during the cap tightening process, improving the interface concentricity when the cap is assembled with the to-be-assembled part 200, thereby creating good conditions for the cap to be accurately and correctly tightened on the to-be-assembled part 200, and ensuring the quality and efficiency of the entire cap assembly process.

[0053] Optionally, as shown in Figure 6 and Figure 7 , the positioning portion 133 further comprises a first movable air cylinder 1333, and one end of the first movable air cylinder 1333 is connected with one end of each of the plurality of clamping positioning pieces 1332 away from the carrier 140, so as to drive the clamping positioning pieces 1332 to move along the horizontal direction to approach or move away from the carrier 140.

[0054] Specifically, as shown in Figure 6 , the first movable air cylinder 1333 is fixedly connected with the positioning plate 1331 through the end thereof, so that the power output of the air cylinder can directly act on the clamping positioning piece 1332. When the first movable air cylinder 1333 receives a control signal to start working, it can generate a pushing force or a pulling force in the horizontal direction, thereby driving the clamping positioning piece 1332 to move along the horizontal direction.

[0055] When it is necessary to position the to-be-assembled part 200, the first movable air cylinder 1333 drives the clamping positioning piece 1332 to move along the horizontal direction to approach the carrier 140, until the clamping positioning piece 1332 contacts and firmly fixes the to-be-assembled part 200 on the carrier 140, so as to ensure that the to-be-assembled part 200 does not shift or shake during the cap tightening process; while completing the tightening operation or replacing the to-be-assembled part 200, the first movable air cylinder 1333 drives the clamping positioning piece 1332 to move along the horizontal direction to move away from the carrier 140, so as to provide sufficient space for the movement of the carrier 140, the loading and unloading of the to-be-assembled part 200 and other operations, so that the entire cap assembly process can be carried out in an orderly manner, and the automation degree and working efficiency of the production line are improved.

[0056] Optionally, as shown in Figure 6 and Figure 7As shown, the positioning part 133 further comprises a plurality of second movable air cylinders 1334, which are respectively arranged opposite to the plurality of clamping positioning members 1332, and each of the second movable air cylinders 1334 is connected with one clamping positioning member 1332; the clamping positioning member 1332 comprises two clamping parts, and the second movable air cylinder 1334 is used to drive the two clamping parts to move close to or away from each other.

[0057] Specifically, as shown in Figure 6 and Figure 7 , the second movable air cylinder 1334 serves as a power unit to provide the clamping positioning member 1332 with accurate and flexible control capability. Each clamping positioning member 1332 is composed of two clamping parts, which are used to directly contact the to-be-assembled part 200 to limit the to-be-assembled part 200. The second movable air cylinder 1334 is connected with the two clamping parts, and it can generate different directions of thrust or pull force according to the movement of the internal piston. Such force acting on the clamping parts will cause the two clamping parts to move relatively, i.e., move close to or away from each other.

[0058] When it is needed to clamp the to-be-assembled part 200, the second movable air cylinder 1334 pushes the two clamping parts to move close to each other until tightly clamping the to-be-assembled part 200, and relies on the friction force and clamping force to stabilize the to-be-assembled part 200 at a specific position; while when it is needed to release the to-be-assembled part 200, the second movable air cylinder 1334 drives the two clamping parts to move away from each other to release the to-be-assembled part 200, so as to carry out subsequent operations such as replacement of the to-be-assembled part 200 or movement of the carrier 140, etc. Such adjustable clamping mode greatly improves the adaptability and flexibility of the positioning part 133, and guarantees the efficient and accurate operation of the cap assembly process.

[0059] Optionally, as shown in Figure 3 , the positioning part 133 further comprises a second linear motor 1335 connected with the plurality of clamping positioning members 1332, which is used to drive the clamping positioning member 1332 to move in the vertical direction to adjust the relative height difference with the to-be-assembled part 200.

[0060] When the second linear motor 1335 receives a control signal to start running, it can exert a thrust or pull force on the clamping positioning member 1332 connected therewith in the vertical direction. The clamping positioning member 1332 moves up or down in the vertical direction under the driving of such force.

[0061] In the actual scene of the cap assembly, due to the different heights of the different to-be-assembled parts 200, the vertical movement adjustment of the clamping positioning part 1332 driven by the second linear motor 1335 can accurately match the actual height position of the to-be-assembled part 200, and eliminate or reduce the relative height difference between the two. In this way, whether in the initial clamping positioning stage or in the subsequent cap tightening process, the clamping positioning part 1332 can always be closely matched with the to-be-assembled part 200 at the optimal height position, avoiding problems such as unstable clamping, cap tightening deviation, etc. caused by inconsistent height, thereby effectively improving the quality and efficiency of the cap assembly, and ensuring the stable operation of the entire assembly production line.

[0062] The above only describes optional embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.

[0063] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present application will not describe various possible combinations again.
