[0064] The embodiment of the utility model discloses an assembly device for assembling a sensor assembly 1, referring to Figure 1 The sensor assembly 1 includes a sensor body 11, a bracket 12, a connecting rod 13 and a ball head 14.

[0065] refer to Figure 3 , Figure 6 and Figure 8 The assembly device disclosed in this embodiment includes a turntable 2, a locking mechanism, a ball head mounting mechanism 5 and a connecting rod mounting mechanism 6. The turntable 2 can rotate along its own axis, and the turntable 2 can be driven by a motor to run. The turntable 2 is provided with a clamping mechanism 3, which is used to fix the sensor body 11, the bracket 12 and the connecting rod 13. The turntable 2 can drive the clamping mechanism 3 to rotate to the third position (such as Figure 3 As shown in the middle area C) and the fourth station (as shown in Figure 3As shown in the middle area D). The locking mechanism is arranged on the third station, and the locking mechanism is used to lock the sensor body 11 to the bracket 12 when the clamping mechanism 3 rotates to the third station, so that the sensor body 11 and the bracket 12 are connected; illustratively, the locking mechanism is a screw locking machine, and the screw locking machine uses a screw 16 to lock the sensor body 11 to the bracket 12 when the clamping mechanism 3 rotates to the third station, so that the sensor body 11 and the bracket 12 are connected. The ball head installation mechanism 5 is arranged on the third station, and the ball head installation mechanism 5 is used to install the ball head 14 on the connecting rod 13 when the clamping mechanism 3 rotates to the third station. The connecting rod installation mechanism 6 is arranged on the fourth station, and the connecting rod installation mechanism 6 is used to install the connecting rod 13 on the sensor body 11 when the clamping mechanism 3 rotates to the fourth station.

[0066] By adopting the above technical scheme, the sensor body 11, the bracket 12 and the connecting rod 13 are all fixed on the clamping mechanism 3, and the clamping mechanism 3 is made to rotate with the turntable 2. When the turntable 2 rotates to the third position, the locking mechanism locks the sensor body 11 on the bracket 12 to fix the sensor body 11 and the bracket 12. The ball head installation mechanism 5 installs the ball head 14 on the connecting rod 13 to fix the ball head 14 and the connecting rod 13. Then the turntable 2 rotates to the fourth position, and the connecting rod installation mechanism 6 installs the connecting rod 13 on the sensor body 11. In this way, the assembly of the sensor assembly 1 is completed. The assembly device provided by the utility model can realize the automatic assembly of the sensor assembly 1, which not only improves the assembly efficiency but also reduces the damage to the product caused by improper operation.

[0067] Alternatively, if Figure 2 As shown, the two ends of the connecting rod 13 are respectively provided with a first groove 131 and a second groove 132. Figure 3 and Figure 5 As shown, along the rotation direction of the turntable 2 (such as Figure 3 The R direction in FIG. 1 shows), a second station is provided upstream of the third station (as shown in FIG. Figure 3 As shown in the middle area B), the turntable 2 can drive the clamping mechanism 3 to rotate from the second station to the third station. The assembly device also includes a grease coating mechanism 7, which is arranged on the second station. The grease coating mechanism 7 is used to coat grease in the first groove 131 and the second groove 132 when the clamping mechanism 3 rotates to the second station.

[0068] Alternatively, if Figure 5As shown, the grease coating mechanism 7 includes: a storage tank, a needle 71, a first drive mechanism and a second drive mechanism. The storage tank is used to store grease. The needle 71 is connected to the storage tank, and the needle 71 is used to apply grease to the first groove 131 and the second groove 132. Specifically, the needle 71 and the storage tank are connected by a pipeline, and a quantitative valve is also provided on the pipeline for quantitatively controlling the grease provided by the needle 71. The first drive mechanism is connected to the needle 71, and the first drive mechanism is used to drive the needle 71 to move in a vertical direction (such as Figure 6 The second drive mechanism is connected to the needle 71, and the second drive mechanism is used to drive the needle 71 to move in the horizontal direction (as shown in the Y direction). Figure 5 The first driving mechanism and the second driving mechanism drive the needle 71 to move so that the needle 71 is close to the first groove 131 and the second groove 132, and grease is applied to the first groove 131 and the second groove 132 to increase the lubricity between the parts. The above technical solution can improve the automation and standardization of grease application.

[0069] Alternatively, if Figure 4 As shown, the bracket 12 is provided with a threaded hole, the sensor body 11 is provided with a mounting hole and a connecting ball head 111, and the clamping mechanism 3 includes: a first clamping member 31, a second clamping member 32 and a third clamping member 33. Among them, the first clamping member 31 is used to clamp the connecting rod 13. When the connecting rod 13 is located in the first clamping member 31, the first groove 131 and the second groove 132 are both facing upward. The second clamping member 32 is used to clamp the sensor body 11. When the sensor body 11 is located in the second clamping member 32, the connecting ball head 111 faces upward (as shown in FIG. 1 ). Figure 7 The third clamping member 33 is used to clamp the bracket 12. When the bracket 12 is located in the third clamping member 33, the mounting hole is located above the threaded hole and the axis of the mounting hole coincides with the axis of the threaded hole, so that the locking mechanism can pass the screw through the mounting hole and the threaded hole in sequence for locking.

[0070] By adopting the above technical solution, the sensor body 11, the bracket 12 and the connecting rod 13 are respectively fixed on the corresponding clamping members, which can ensure that the subsequent assembly work can be carried out smoothly.

[0071] Alternatively, if Figure 6 As shown, the ball head installation mechanism 5 includes: a first clamping jaw 51 and a third driving mechanism. The first clamping jaw 51 is used to grab the ball head 14. Specifically, the ball head 14 is transported to the second station by a conveying device. For example, the conveying device is a vibrating conveyor. The third driving mechanism is used to drive the first clamping jaw 51 to move in a vertical direction to press the ball head 14 into the first groove 131 so that the ball head 14 is fixed to the connecting rod 13.

[0072] Optionally, the assembly device further includes a flipping mechanism. The flipping mechanism is disposed on the third station, and is used to flip the connecting rod 13 180 degrees after the ball head mounting mechanism 5 mounts the ball head 14 on the connecting rod 13, so that the second groove 132 faces the opposite direction to the connecting ball head 111. Specifically, after the connecting rod 13 is flipped 180 degrees, the second groove 132 faces downward (in contrast to the connecting ball head 111). Figure 7 The connecting ball head 111 faces upward.

[0073] Alternatively, if Figure 4 As shown, the clamping mechanism 3 further includes a fourth clamping member 34. Exemplarily, the first clamping member 31, the second clamping member 32, the third clamping member 33 and the fourth clamping member 34 are all substrates provided with positioning grooves, and the shape of each positioning groove is respectively adapted to the outer contour shape of the corresponding clamped member, and when the clamped member is placed in the positioning groove, the positioning groove can limit the clamped member to prevent the clamped member from moving.

[0074] The flipping and moving mechanism includes: a second clamping jaw, a fourth driving mechanism and a fifth driving mechanism. The second clamping jaw is used to grab the connecting rod 13; the fourth driving mechanism is used to drive the second clamping jaw to rotate so that the connecting rod 13 flips 180 degrees around its own axis; the fifth driving mechanism is used to drive the second clamping jaw to move so that the flipped connecting rod 13 can move from the first clamping member 31 to the fourth clamping member 34, and the flipped connecting rod 13 is placed in the fourth clamping member 34 for fixing.

[0075] Alternatively, if Figure 7 and Figure 8 As shown, the connecting rod installation mechanism 6 includes: a third clamping jaw 61 and a sixth driving mechanism. The third clamping jaw 61 is used to grab the connecting rod 13 on the fourth clamping member 34. The sixth driving mechanism is used to drive the third clamping jaw 61 to move so that the second groove 132 is matched with the connecting ball head 111. Specifically, the first driving mechanism, the second driving mechanism, the third driving mechanism, the fourth driving mechanism, the fifth driving mechanism and the sixth driving mechanism can be electric cylinders, oil cylinders or air cylinders.

[0076] By adopting the above technical solution, the connecting rod installation mechanism 6 fixes the connecting rod 13 with the ball head 14 installed to the sensor body 11 and the bracket 12, so that the four parts are assembled together to complete the entire assembly process.

[0077] Alternatively, if Figure 3 As shown, along the rotation direction of the turntable 2, a first station (such as Figure 3As shown in the middle area A), the turntable 2 can drive the clamping mechanism 3 to rotate from the first station to the second station, and the assembly device also includes a first detection mechanism 9 and a control system. Among them, the first detection mechanism 9 is arranged on the first station, and the first detection mechanism 9 is used to detect whether the sensor body 11, the bracket 12 and the connecting rod 13 are located at the preset position, and send a first signal to the outside when the sensor body 11, the bracket 12 and the connecting rod 13 are all located at the preset position, and send a second signal to the outside when at least one of the sensor body 11, the bracket 12 and the connecting rod 13 is not located at the preset position; specifically, the first detection mechanism 9 is a camera. The control system is electrically connected to the first detection mechanism 9, and the control system is used to control the turntable 2 to rotate when receiving the first signal, so as to drive the turntable 2 to rotate to the second station, and control the turntable 2 to stop rotating when receiving the second signal.

[0078] By adopting the above technical solution, the first detection mechanism 9 can detect the positions of the sensor body 11, the bracket 12 and the connecting rod 13, thereby preventing assembly failure caused by incorrect placement of the above three.

[0079] Alternatively, if Figure 3 As shown, the assembly device further includes a second detection mechanism 10. The second detection mechanism 10 is disposed on the second station, and the second detection mechanism 10 is electrically connected to the control system. The second detection mechanism 10 is used to detect whether there is grease in the first groove 131 and the second groove 132. Specifically, the second detection mechanism 10 is a camera. When grease exists in both the first groove 131 and the second groove 132, the control system controls the turntable 2 to rotate from the second station to the third station; when at least one of the first groove 131 and the second groove 132 is not coated with grease, the control system controls the turntable 2 to stop running.

[0080] By adopting the above technical solution, the second detection mechanism 10 detects whether there is grease in the first groove 131 and the second groove 132 to prevent the phenomenon of grease leakage.

[0081] Optionally, the assembly device further includes: a third detection mechanism, a fourth detection mechanism and a fifth detection mechanism. Among them, the third detection mechanism is arranged on the third station, the third detection mechanism is electrically connected to the control system, and the third detection mechanism is used to detect whether the pressure value applied by the locking mechanism to the screw is greater than or equal to a preset value. The fourth detection mechanism is arranged on the third station, the fourth detection mechanism is electrically connected to the control system, and the fourth detection mechanism is used to detect whether the depth value of the screw inserted into the threaded hole is greater than or equal to a preset value. The fifth detection mechanism is arranged on the third station, the fifth detection mechanism is electrically connected to the control system, and the fifth detection mechanism is used to detect whether the torque value provided by the locking mechanism for the screw is greater than or equal to a preset value. When the pressure value provided by the locking mechanism is less than the preset value, the depth value of the screw inserted into the threaded hole is less than the preset value, and the torque value provided by the locking mechanism for the screw is less than the preset value, the control system controls the locking mechanism to operate; when the pressure value provided by the locking mechanism is greater than or equal to the preset value, the depth value of the screw inserted into the threaded hole is greater than or equal to the preset value, or the torque value provided by the locking mechanism for the screw is greater than or equal to the preset value, the control system controls the locking mechanism to stop operating. Specifically, the third detection mechanism is a pressure sensor, the fourth detection mechanism is a displacement sensor, and the fifth detection mechanism is a torque sensor.

[0082] By adopting the above technical solution, the third detection mechanism, the fourth detection mechanism and the fifth detection mechanism respectively detect the pressure, torque and displacement during the screw installation process, which can prevent product damage caused by excessive pressure, excessive torque or excessive displacement.

[0083] Alternatively, if Figure 3 and Figure 8 As shown, the assembly device also includes a sixth detection mechanism 15. The sixth detection mechanism 15 is arranged on the fourth station, and the sixth detection mechanism 15 is electrically connected to the control system. The sixth detection mechanism 15 is used to detect whether the connecting ball head 111 is located in the second groove 132. Specifically, the sixth detection mechanism 15 is a camera. When the connecting ball head 111 is located in the second groove 132, the control system controls the turntable 2 to rotate from the fourth station to the first station, and the operator affixes the model label of the sensor component 1 and unloads the assembled sensor component 1; when the connecting ball head 111 is not located in the second groove 132, the control system controls the turntable 2 to stop running.

[0084] By adopting the above technical solution, the sixth detection mechanism 15 can prevent unqualified products caused by the mismatch between the positions of the connecting ball head 111 and the second groove 132.

[0085] The process of assembling the sensor assembly by the assembly device provided in this embodiment is as follows:

[0086] The motor drives the turntable 2 to run in the rotation direction. When the clamping mechanism rotates to the first position, the operator places the sensor body 11, the bracket 12 and the connecting rod 13 into the first clamping member 31, the second clamping member 32 and the third clamping member 33 respectively for positioning. At this time, the first groove 131 and the second groove 132 are both facing upwards, and the first detection mechanism 9 detects the positions of the sensor body 11, the bracket 12 and the connecting rod 13 respectively and sends signals to the control system. When at least one of the sensor body 11, the bracket 12 and the connecting rod 13 is not in the preset position, the first detection mechanism 9 sends a second signal to the outside, and the control system receives the second signal and controls the turntable 2 to stop rotating; when the sensor body 11, the bracket 12 and the connecting rod 13 are all in the preset position, the first detection mechanism 9 sends a first signal to the outside, and the control system receives the first signal and controls the turntable 2 to continue rotating. When the clamping mechanism rotates to the second station, the grease coating mechanism 7 located at the second station coats grease into the first groove 131 and the second groove 132. The second detection mechanism 10 is used to detect whether there is grease in the first groove 131 and the second groove 132. When at least one of the first groove 131 and the second groove 132 does not have grease, the control system controls the turntable 2 to stop running. When grease exists in both the first groove 131 and the second groove 132, the control system controls the turntable 2 to rotate. When the clamping mechanism rotates from the second station to the third station, the ball head installation mechanism 5 located at the third station installs the ball head 14 on the connecting rod 13. At this time, the ball head 14 and the connecting rod 13 are fixed. Then the flipping movement mechanism lifts the connecting rod 13 up to a certain height and flips the connecting rod 13 180 degrees around its own axis, so that the second groove 132 is opposite to the direction of the connecting ball head 111. Then, the flipped connecting rod 13 is placed in the fourth clamping member 34. At the same time, the locking mechanism uses screws to lock the sensor body 11 to the bracket 12, so that the sensor body 11 and the bracket 12 are connected. During the locking process, The third detection mechanism, the fourth detection mechanism and the fifth detection mechanism located above the third station respectively detect the pressure, torque and displacement during the screw installation process. When the pressure value applied by the locking mechanism to the screw is greater than or equal to the preset value, or the depth value of the screw inserted into the threaded hole is greater than or equal to the preset value, or the torque value provided by the locking mechanism to the screw is greater than or equal to the preset value, the control system controls the locking mechanism to stop running; when the pressure value provided by the locking mechanism to the screw is less than the preset value, the depth value of the screw inserted into the threaded hole is less than the preset value, and the torque value provided by the locking mechanism to the screw is less than the preset value, the control system controls the locking mechanism to run. When the ball head installation mechanism, the flip movement mechanism and the locking mechanism complete the action, the control system controls the turntable 2 to continue to rotate.When the clamping mechanism rotates from the third station to the fourth station, the connecting rod installation mechanism 6 lifts up the connecting rod 13 located in the fourth clamping member 34 and makes the second groove 132 correspond to the position of the connecting ball head 111, and then presses downward to make the second groove 132 cooperate with the connecting ball head 111, and installs the connecting rod 13 on the sensor body 11. At this time, the entire assembly process of the sensor assembly is completed. The sixth detection mechanism 15 located at the fourth station detects whether the connecting ball head 111 is located in the second groove 132. When the connecting ball head 111 is not located in the second groove 132, the control system controls the turntable 2 to stop running; when the connecting ball head 111 is located in the second groove 132, the control system controls the turntable 2 to rotate from the fourth station to the first station, and the operator attaches a label corresponding to its model on the assembled sensor assembly 1, and removes the assembled sensor assembly 1 from the clamping mechanism 3.

[0087] To improve production efficiency, such as Figure 3 As shown, four clamping mechanisms 3 may also be provided on the turntable 2, namely, a first clamping mechanism, a second clamping mechanism, a third clamping mechanism and a fourth clamping mechanism, and the four clamping mechanisms 3 are arranged at equal intervals along the circumference of the turntable 2. Specifically, the angle between two adjacent clamping mechanisms 3 is 90 degrees. When the turntable 2 stops rotating, the first station, the second station, the third station and the fourth station each correspond to a clamping mechanism 3.

[0088] By adopting the above technical solution and providing four clamping mechanisms 3 , the devices on four workstations can work simultaneously, thereby improving the assembly efficiency of the sensor assembly 1 .

[0089] The assembly device provided by the utility model can improve the assembly efficiency of the sensor assembly and avoid damage to the product caused by improper manual assembly methods.
