Description

Technical Field

[0001] This invention relates to the field of motor manufacturing, and more particularly to a motor rubber cover PQ side terminal assembly machine. Background Technology

[0002] Brushed motors are widely used actuators in automobiles. A brushed motor consists of a housing and a motor cover at the end. During operation, external current is transmitted through the conductive terminals on the motor cover, thereby driving the brushed motor to control the operation of mechanisms such as windows, wipers, door locks, fuel pump, and throttle.

[0003] The aforementioned motor cover is used to support conductive terminals for electrical connection and also serves as an insulating cover component. This motor cover typically features two types of conductive terminals: a P-side terminal and a Q-side terminal, arranged in a mirror-symmetrical configuration. These terminals are used to form the electrical path connection for the motor, satisfying the motor's power supply and circuit continuity requirements.

[0004] In the existing technology, due to the limitations of structural symmetry and functional differentiation, the two types of motor covers that support P-side terminals and Q-side terminals require two separate assembly lines for material preparation, processing and testing of the two types of terminals. This results in low production efficiency and increases costs for equipment investment, mold management and material control, which is not conducive to large-scale production and the improvement of product versatility.

[0005] Therefore, the aforementioned problems in the existing technology still need to be improved. Summary of the Invention

[0006] The main objective of this invention is to provide a motor cover PQ side terminal assembly machine, which solves the technical problem of low processing efficiency caused by processing the P-side and Q-side terminals of the motor cover through two independent production lines in the prior art through a switchable terminal pre-assembly mechanism and a clamping mechanism.

[0007] The first aspect of this invention provides a motor cover PQ side terminal assembly machine, comprising a feeding belt and a turntable, the turntable rotating sequentially along the following stations: a top extension rotary exchange mechanism for placing a first motor cover to be processed, transported by the feeding belt, onto the turntable, and for placing a second motor cover processed on the turntable onto the feeding belt; a vision inspection mechanism for detecting whether the first motor cover is a target motor cover; a terminal pre-assembly mechanism for switching between a first point and a second point to pre-assemble a P-side terminal or a Q-side terminal onto the first motor cover; and a clamping mechanism for switching between a third point and a fourth point. The mechanism is used to press the P-side terminal or Q-side terminal pre-installed on the first motor cover; a height detection mechanism is used to detect whether the installation height of the P-side terminal or Q-side terminal on the first motor cover meets the preset value; a defective material discharge mechanism is used to obtain the pressure value detected by the pressing mechanism, the height value detected by the height detection mechanism, and the detection result of the vision inspection mechanism. When any one of the pressure value, the detection value, or the detection result of the first motor cover is unqualified, the defective material discharge mechanism recycles the first motor cover; otherwise, the turntable transports the first motor cover to the top extension rotary exchange mechanism.

[0008] Preferably, the top-extension rotary exchange mechanism includes a first gripper, a second gripper, and a rotating shaft. The first gripper and the second gripper exchange positions between the feed belt and the turntable under the drive of the rotating shaft.

[0009] Preferably, the terminal pre-installation mechanism includes: a gripper assembly for gripping a P-side terminal or a Q-side terminal and pre-installing the P-side terminal or the Q-side terminal onto the motor cover; a first drive assembly for driving the gripper assembly to move between a gripping position and a pre-installation position; wherein the gripping position is the position where the gripper assembly grips the P-side terminal or the Q-side terminal, and the pre-installation position is the position where the gripper assembly pre-installs the P-side terminal or the Q-side terminal onto the motor cover; and a changing assembly disposed between the gripper assembly and the first drive assembly, the changing assembly being connected to both the gripper assembly and the first drive assembly, and the changing assembly driving the gripper assembly to move between a first position and a second position; when the gripper assembly is at the first position, the gripper assembly is directly facing one of the P-side terminal or the Q-side terminal at the gripping position; when the gripper assembly is at the second position, the gripper assembly is directly facing the other of the P-side terminal or the Q-side terminal at the gripping position.

[0010] Preferably, the changing component includes a first slide rail and a first driving member, wherein the first slide rail and the movement trajectory direction of the first driving member have a preset angle, and the gripper assembly is slidably connected to the first slide rail; the first driving member is connected to the gripper assembly, and the first driving member is used to drive the gripper assembly to reciprocate along the first slide rail.

[0011] Preferably, the gripper assembly includes a gripper structure and a pre-compression structure, wherein the gripper structure includes two gripping hook elements, and the pre-compression structure is disposed between the two gripping hook elements; the pre-compression structure includes an elastic member and a supporting member, the elastic member abutting against the supporting member and outputting tension to the supporting member, and the supporting member is used to abut the end of the P-side terminal or the Q-side terminal.

[0012] Preferably, the clamping mechanism includes: a clamping assembly for pressing a P-side terminal or a Q-side terminal pre-installed on a motor cover to clamp the P-side terminal or the Q-side terminal to the motor cover; a second drive assembly for driving the clamping assembly to move up and down to clamp the P-side terminal or the Q-side terminal; and a switching assembly disposed between the clamping assembly and the second drive assembly, connected to both the clamping assembly and the second drive assembly; the switching assembly for driving the clamping assembly to move between a third position and a fourth position; when the clamping assembly is at the third position, it is clamping one of the P-side terminal or the Q-side terminal; when the clamping assembly is at the fourth position, it is clamping the other of the P-side terminal or the Q-side terminal.

[0013] Preferably, the switching component includes a second drive member and a third slide rail, wherein the clamping component is slidably connected to the third slide rail, and the second drive member is connected to the clamping component to drive the clamping component to reciprocate between the third point and the fourth point along the third slide rail.

[0014] Preferably, the clamping assembly includes a pressure sensor for detecting the pressure value of the clamping assembly pressing the P-side terminal or the Q-side terminal.

[0015] Preferably, the height detection mechanism includes a third drive component, a pre-pressure component, a transmission component, and a displacement sensor. The third drive component is connected to the pre-pressure component and drives the pre-pressure component closer to the motor cover. The transmission component is slidably connected to the pre-pressure component and is signal-connected to the displacement sensor. The relative positions of the pre-pressure component and the displacement sensor are fixed. During the process of the third drive component driving the pre-pressure component closer to the motor cover, the transmission component first contacts and presses the top of the P-side terminal or Q-side terminal. The third drive component continues to drive the pre-pressure component and the displacement sensor closer to the motor cover until the pre-pressure component abuts against the motor cover. The displacement sensor detects the displacement of the transmission component relative to the pre-pressure component and determines the height value of the P-side terminal or Q-side terminal on the motor cover based on the displacement.

[0016] Preferably, the conductive component and the pre-compression component are slidably connected as follows: the pre-compression component is provided with a fifth slide rail, and the conductive component is disposed on the fifth slide rail; when the conductive component contacts and presses the top of the P-side terminal or the Q-side terminal, the conductive component remains stationary, and the fifth slide rail slides relative to the conductive component, so that the pre-compression component continues to approach the motor cover under the drive of the drive component.

[0017] In summary, the motor cap PQ side terminal assembly machine provided by this invention aims to solve the problems of low production efficiency, high cost, and poor versatility in the prior art, which requires two independent assembly lines for P-side and Q-side terminals. This assembly machine includes a feeding belt, a turntable, and various workstation mechanisms. The turntable drives the motor caps to be processed through the following stations sequentially: top-extension rotation exchange, visual inspection, terminal pre-assembly, clamping, height detection, and defective material discharge. The terminal pre-assembly mechanism can switch between two positions to pre-assemble either the P-side or Q-side terminals, and the clamping mechanism simultaneously switches positions to complete the clamping. This solution allows one assembly line to adapt to the assembly of two types of terminals, eliminating the need for separate material preparation, processing, and inspection lines, significantly improving production efficiency, reducing equipment investment, mold management, and material control costs, enhancing product versatility, and ensuring product assembly quality through multi-mechanism inspection.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0046] Brushed motors are widely used actuating drive components in automobiles. A brushed motor consists of a housing and a rubber cover at the end. During operation, external current is transmitted through the conductive terminals on the motor cover, thereby driving the brushed motor to control the operation of mechanisms such as windows, wipers, door locks, fuel pump, and throttle. The aforementioned motor cover serves to support the conductive terminals for electrical connection and also acts as an insulating cover component. Figures 1 to 4 As shown, the motor cover 10 is typically equipped with two types of conductive terminals, namely P-side terminal 11 and Q-side terminal 12. The two are arranged in a mirror symmetrical manner and are used to form the electrical path connection of the motor to meet the requirements of motor power supply and circuit conduction.

[0047] Due to the structural symmetry and functional distinction of the two types of motor covers that support P-side terminal 11 and Q-side terminal 12, the preparation, processing and testing of the two types of terminals require two separate assembly lines, resulting in low production efficiency. This also increases the costs of equipment investment, mold management and material control, which is not conducive to large-scale production and the improvement of product versatility.

[0048] To address the aforementioned issues, this application provides a motor cover PQ side terminal assembly machine. Through a switchable terminal pre-assembly mechanism and a clamping mechanism, it solves the technical problem in the prior art where the P-side and Q-side terminals of the motor cover are processed through two independent production lines, resulting in low processing efficiency.

[0049] First, the motor cover PQ side terminal assembly machine provided in the embodiments of this application will be described in general as follows.

[0050] like Figure 5 and Figure 6 As shown, the motor cover PQ side terminal assembly machine provided in this application embodiment includes a feeding belt 01 and a turntable, which rotates sequentially along the following stations:

[0051] Top extension and rotation exchange mechanism 02, CCD vision inspection mechanism 03, first terminal pre-assembly mechanism 04-1, first clamping station 05-1, second terminal pre-assembly mechanism 04-2, second clamping mechanism 05-2, height detection mechanism 06, defective material discharge station 07.

[0052] The feeding belt 01 transports the motor cover 10 to be processed to the designated position. The first gripper of the top extension and rotation exchange mechanism 02 picks up the first motor cover 10 to be processed and places it in the initial position of the turntable. At the same time, the second gripper picks up the second motor cover that has been processed on the turntable and places it in the feeding belt so that the feeding belt can send the second motor cover into the next process.

[0053] Afterwards, the turntable drives the motor-driven rubber cover 10 to each workstation in sequence to complete processing and inspection. The specific workflow of each workstation is as follows:

[0054] The visual inspection unit 03 identifies the appearance features and model markings of the motor cover 10, determines whether the current motor cover 10 is the preset processing model of this batch, filters out non-target model products, and avoids incorrect processing in subsequent processes.

[0055] The first terminal pre-installation mechanism 04-1 grabs the first terminal among the P-side terminal 11 or the Q-side terminal 12 and pre-inserts it into the corresponding mounting hole of the motor cover 10. The pre-insertion process retains a preset margin to ensure that the terminal is stable and does not fall off and is easy to tighten later.

[0056] The first clamping station 05-1 performs a second clamping on the pre-installed first terminal. By using pressure to coordinate positioning, it ensures that the terminal is installed in place and eliminates problems such as terminal floating or tilting.

[0057] The second terminal pre-installation mechanism 04-2 is structurally symmetrical to the first terminal pre-installation mechanism 04-1, and grasps and pre-inserts the second terminal in either the P-side terminal 11 or the Q-side terminal 12 according to the same principle.

[0058] The second clamping mechanism 05-2 clamps and fixes the second pre-inserted terminal, completing the entire process of pre-installation and clamping of the two terminals.

[0059] The height detection mechanism 06 adopts a contact displacement detection method, using the motor cover 10 reference surface as a reference, to measure the terminal installation height and determine whether the height deviation is within the allowable tolerance range.

[0060] Defective material discharge station 07 classifies and discharges unqualified products according to the test results, distinguishing them into three categories: CCD test failure, pressing abnormality, and height deviation. Qualified products are sent back to the feeding belt 01 by the top extension and rotation exchange mechanism 02 and enter the next processing step.

[0061] Based on the above overall architecture, the various mechanisms in the motor cover PQ side terminal assembly machine provided in this application embodiment are described in detail below.

[0062] like Figure 7 As shown, the top extension and rotation exchange mechanism 02 includes a first gripper 1301, a second gripper 1302 and a rotating shaft 1303. The first gripper 1301 and the second gripper 1302 exchange positions between the feeding belt 01 and the turntable under the drive of the rotating shaft 1303.

[0063] In this embodiment, the first gripper 1301 and the second gripper 1302 are symmetrically arranged and form a rotary structure under the drive of the rotating shaft 1303. Each rotation causes the first gripper 1301 and the second gripper 1302 to symmetrically switch positions by 180°. In the specific working process, when the first motor cover 10 to be processed reaches the preset position, the first gripper 1301 and the second gripper 1302 fall simultaneously. At this time, the first gripper 1301 grabs the first motor cover 10 to be processed on the feeding belt 01, and the second gripper 1302 grabs the second motor cover 10 that has been processed on the turntable. Then, the rotating shaft 1303 drives the first gripper 1301 and the second gripper 1302 to rotate and switch positions. As a result, the first motor cover 10 to be processed enters the initial position of the turntable and begins the subsequent processing steps. The second motor cover 10 that has been processed returns to the feeding belt 01 and enters other subsequent processing processes.

[0064] The top-extension rotary exchange mechanism 02 provided in this application embodiment can quickly load and unload materials through rotational cooperation, resulting in high processing efficiency.

[0065] It should be noted that the above two concepts, the first motor cover and the second motor cover, are only used to distinguish between the motor cover to be processed and the motor cover after processing. For ease of understanding, they will be referred to as motor cover 10 below.

[0066] Optionally, such as Figure 8 As shown, the visual inspection mechanism is specifically a CCD visual inspection mechanism 03, which includes an illumination module 1401 and an inspection module 1402. The CCD visual inspection mechanism 03 is used to identify the appearance features and model markings of the motor cover 10, determine whether the current motor cover 10 is the preset processing model of this batch, screen out non-target model products, and avoid misprocessing in subsequent processes.

[0067] In this embodiment, the terminal pre-installation mechanism includes two identical and symmetrical mechanisms. This is because both the P-side terminal 11 and the Q-side terminal 12 contain two symmetrically arranged terminals. The two terminal pre-installation mechanisms are symmetrically arranged and have the same working principle and structural composition. The following text will take one of the terminal pre-installation mechanisms (first terminal pre-installation mechanism 04-1) as an example for detailed explanation. The other terminal pre-installation mechanism (second terminal pre-installation mechanism 04-2) will not be described in detail.

[0068] The detailed plan is as follows:

[0069] Please see Figures 9 to 12 The terminal pre-installation mechanism provided in this application includes: a gripper assembly 300, which grips the P-side terminal 11 or the Q-side terminal 12 and pre-installs the P-side terminal 11 or the Q-side terminal 12 onto the motor cover 10; and a first drive assembly 200, which drives the gripper assembly 300 to move between a gripping position 1a and a pre-installation position 1b; wherein, the gripping position 1a is the position where the gripper assembly 300 grips the P-side terminal 11 or the Q-side terminal 12, and the pre-installation position 1b is the position where the gripper assembly 300 pre-installs the P-side terminal 11 or the Q-side terminal 12 onto the motor cover 10. A changing component 100 is disposed between the gripper assembly 300 and the first drive assembly 200. The changing component 100 is connected to both the gripper assembly 300 and the first drive assembly 200. The changing component 100 is used to drive the gripper assembly 300 to move between a first position and a second position. When the gripper assembly 300 is at the first position, the gripper assembly 300 is facing one of the P-side terminal 11 or the Q-side terminal 12 at the gripping position 1a. When the gripper assembly 300 is at the second position, the gripper assembly 300 is facing the other of the P-side terminal 11 or the Q-side terminal 12 at the gripping position 1a.

[0070] In this embodiment, as Figures 10 to 12As shown, the first terminal feeder 08-1 accurately conveys the P-side terminal 11 to the gripping position 1a. The gripper assembly 300 grips the P-side terminal 11, and then the first drive assembly 200 moves along... Figures 10 to 12 As shown by arrow B, the gripper assembly 300 is smoothly moved to the pre-installation position 1b. At the pre-installation position 1b, the gripper assembly 300 pre-inserts the P-side terminal 11 into the mounting hole of the motor cover 10, completing the pre-installation of a single P-side terminal 11. The equipment repeats this action cyclically to achieve continuous processing. When the production line completes the batch production of the P-side terminal 11 covers and needs to switch to producing the Q-side terminal 12 covers, the first terminal feeder 08-1 switches its feeding mechanism, conveying the Q-side terminal 12 to the gripping position 1a. Because the Q-side terminal 12 is mirror-symmetrical to the P-side terminal 11, its position at the gripping position 1a is offset relative to the P-side terminal 11. At this time, the changeover component 100 drives the gripper component 300 to switch between the first position and the second position in the direction of arrow A. When the gripper component 300 is at the first position, it is facing the P-side terminal 11 of the gripping position 1a; when it is at the second position, it is facing the Q-side terminal 12 of the gripping position 1a. The pre-installation processing of the two terminals can be quickly switched without changing the tooling or adjusting the overall structure of the equipment.

[0071] Therefore, the solution proposed in this application achieves point switching of the gripper assembly 300 through the changeover component 100, breaking the limitation of traditional two sets of equipment processing P and Q side terminals 12 separately. One set of pre-installed mechanism is compatible with processing two types of symmetrical terminals, eliminating the need for separate line material preparation and multi-equipment management, simplifying the production process, and greatly improving processing efficiency. At the same time, it reduces equipment investment, mold development and material management costs, enhances the versatility of the production line and the capacity for large-scale production, and effectively solves the technical problems of cumbersome procedures, high costs and poor versatility of traditional processing methods.

[0072] It should be noted that the switching drive method of the changeover component 100 can be flexibly selected according to processing requirements. The preferred embodiment provided in this application is as follows:

[0073] Optionally, the changing component 100 includes a first driving member and a first limiting member, wherein the first limiting member is used to limit the movement of the gripper assembly 300 between a first point and a second point along a preset trajectory; the first driving member is connected to the gripper assembly 300 and is used to drive the gripper assembly 300 to reciprocate under the limitation of the limiting member.

[0074] like Figures 10 to 12 As shown, the first limiting member restricts the gripper assembly 300 to move back and forth in a straight line along the direction of arrow A, constraining the motion trajectory to avoid deviation and ensuring that the gripper assembly 300 accurately stops at the first and second points; the first driving member can be a motor or a cylinder to provide stable power to the gripper assembly 300, driving it to complete the point switching under the constraint of the first limiting member, with stable power output and rapid motion response.

[0075] This structure achieves precise 300-degree change of the gripper assembly through the combination of limiting and driving. The movement process is highly controllable and the change accuracy is high, ensuring the alignment accuracy of terminal gripping and pre-installation. The structure is simple and compact, which facilitates equipment integration and maintenance and improves the stability of mechanism operation.

[0076] It should be noted that the replacement component 100 includes multiple implementation methods, and this application provides two preferred solutions:

[0077] Example 1

[0078] like Figures 10 to 12 As shown, the first limiting member includes a first slide rail 110, the first slide rail 110 and the movement trajectory direction of the first drive assembly 200 have a preset angle, and the gripper assembly 300 is slidably connected to the first slide rail 110; the first drive member includes a first motor or a first cylinder, and the first motor or the first cylinder is connected to the gripper assembly 300.

[0079] In this embodiment, the first slide rail 110 extends along the direction of arrow A, forming a preset angle α with the movement trajectory of the first drive assembly 200 in the direction of arrow B. The bottom of the gripper assembly 300 slides in engagement with the first slide rail 110. The output end of the first motor or the first cylinder is directly connected to the gripper assembly 300. After startup, the gripper assembly 300 is driven to slide along the first slide rail 110, realizing the switching between the first position and the second position. The first slide rail 110 provides rigid support and guidance for the gripper assembly 300, with low sliding friction resistance and smooth, non-jamming movement.

[0080] The sliding guide structure has a strong load-bearing capacity and can stably support the gripper assembly 300 with integrated multi-functional modules, preventing the gripper assembly 300 from shifting due to its own weight or motion inertia, thus ensuring the positioning accuracy of the changeover. The sliding guide has a tight fit, low wear during long-term operation, and a long service life, making it suitable for heavy-duty and high-frequency changeover processing scenarios.

[0081] Example 2

[0082] The first limiting member includes a first connecting rod sub-assembly (not shown in the figure), which is connected to the gripper assembly 300 to guide the movement trajectory of the gripper assembly 300 between the first point and the second point; the first driving member includes a first motor or a first cylinder, which is connected to the gripper assembly 300.

[0083] In this embodiment, optionally, the first connecting rod sub-assembly is composed of multiple hinged connecting rods, one end of which is fixedly connected to the first driving assembly 200, and the other end is hinged to the gripper assembly 300. The first motor or the first cylinder drives the connecting rod assembly to extend and swing, thereby driving the gripper assembly 300 to move between the first point and the second point along a preset trajectory. The connecting rod transmission has a fast response speed and the switching action is smooth and efficient.

[0084] The linkage transmission structure is compact, occupies little equipment space, has low motion inertia, and fast switching speed. It is suitable for rapid changeover scenarios of lightweight gripper assembly 300, can match high-speed processing cycle, and improve the overall operating efficiency of the equipment.

[0085] The replacement component 100 has been described in detail above. The specific structure of the first drive component 200 is described below:

[0086] like Figures 10 to 12 As shown, the first drive component 200 includes a first slider 210 and a second slide rail 220, wherein the second slide rail 220 has a preset angle with the movement direction of the changing component 100; the first slider 210 is connected to the changing component 100.

[0087] Optionally, the first drive assembly 200 further includes a first power unit 230, which may be a motor or a cylinder, and is used to drive the first slider 210 to slide along the second slide rail 220.

[0088] In this embodiment, the second slide rail 220 is arranged along the direction of arrow B, forming a preset angle α with the movement trajectory of the conversion component 100 in the direction of arrow A. The first slider 210 is slidably mounted on the second slide rail 220, and its top is fixedly connected to the conversion component 100. External power drives the first slider 210 to slide along the second slide rail 220, causing the conversion component 100 and the gripper assembly 300 to translate between the gripping position 1a and the pre-assembly position 1b, thereby realizing the transfer and pre-assembly of the terminals.

[0089] The first drive assembly 200 adopts a sliding rail and first slider 210 cooperation structure, which has high translational guidance accuracy and smooth movement without shaking, ensuring that the gripper assembly 300 does not deviate or fall off during the transfer of terminals; the sliding rail and the first slider 210 are tightly fitted, with low movement resistance and low operating noise, which can accurately control the transfer stroke and ensure that the terminals are accurately aligned with the mounting holes of the motor cover 10, thus improving the pre-installation accuracy.

[0090] It should be noted that the gripper assembly 300 is designed to meet the processing requirements of P-side terminal 11 and Q-side terminal 12, and works efficiently with the changeover assembly 100. The preferred solution is as follows:

[0091] like Figure 10 and Figure 11As shown, the gripper assembly 300 includes a vertical drive sub-assembly 310, a rotary motion sub-assembly 320, and a terminal gripper 330. The vertical drive sub-assembly 310 is connected to the changing assembly 100 and is used to drive the terminal gripper 330 to move up and down so that the terminal gripper 330 picks up and pre-installs the P-side terminal 11 or the Q-side terminal 12. The rotary motion sub-assembly 320 is connected to both the vertical drive assembly 310 and the terminal gripper 330. The rotary motion sub-assembly 320 is used to rotate the terminal gripper 330 by a preset angle after it picks up the P-side terminal 11 or the Q-side terminal 12 so that the P-side terminal 11 or the Q-side terminal 12 is aligned with the mounting hole of the motor cover 10.

[0092] In this embodiment, after the terminal gripper 330 closes and grips the P-side terminal 11 or the Q-side terminal 12, the vertical drive sub-assembly 310 drives the terminal gripper 330 to rise upwards and disengage from the gripping position 1a. After the first drive assembly 200 moves the gripper assembly 300 to the pre-installation position 1b, the vertical drive sub-assembly 310 drives the terminal gripper 330 downwards to pre-insert the terminal into the preset position of the motor cover 10. Because the insertion parts of the P-side terminal 11 and the Q-side terminal 12 are sheet-like structures, the insertion angle requires precision. After the terminal gripper 330 grips the terminal, the rotational motion sub-assembly 320 drives it to rotate by a preset angle to correct the terminal posture and make it precisely aligned with the mounting hole of the motor cover 10.

[0093] The vertical drive sub-assembly 310 realizes the terminal picking, lifting and pre-installation actions. The rotary motion sub-assembly 320, together with the type-changing assembly 100, accurately corrects the insertion angle of the two types of terminals, solves the problem of symmetrical terminal angle adaptation, and realizes the accurate pre-installation of P-side terminal 11 and Q-side terminal 12 by one set of mechanisms. The installation qualification rate is high and the adaptability is strong.

[0094] It should be noted that the rotary motion sub-assembly 320 can be implemented in various ways, and the preferred solution provided in this application is as follows.

[0095] like Figure 10 and Figure 11 As shown, the rotary motion sub-assembly 320 includes a rotary motor 321, a rotating block 322, and a transmission shaft 323. The rotary motor 321 is connected to the transmission shaft 323 via the rotating block 322, and the transmission shaft 323 is connected to the terminal gripper 330. A position sensor is provided on the rotating block 322, which is used to detect the rotation angle of the rotating block 322.

[0096] In this embodiment, the output shaft of the rotary motor 321 is fixedly connected to the rotating block 322. The rotating block 322 is rigidly connected to the terminal gripper 330 via the transmission shaft 323. After the rotary motor 321 starts, it sequentially drives the rotating block 322 and the transmission shaft 323 to rotate, thereby driving the terminal gripper 330 to rotate by a preset angle. A position sensor is installed on the rotating block 322 to detect the rotation angle of the rotating block 322 in real time. Preferably, the sensor can be a magnetic sensor. Magnets and magnetic sensing elements are respectively provided on the rotary motor 321 and the rotating block 322. When the rotation is in position, the magnet and the sensor are aligned, triggering a position signal to accurately control the rotation angle.

[0097] This transmission structure delivers power directly and responds quickly to rotation, making it suitable for high-speed machining cycles. The position sensor monitors the rotation angle in real time, providing accurate feedback to prevent over-rotation or under-rotation, ensuring precise alignment of the P-side terminal 11 and the Q-side terminal 12 and improving pre-assembly consistency.

[0098] Preferably, to further enhance the precise control of the rotation angle, a physical limiting structure can be added to the position sensor.

[0099] Optionally, the rotary motion subassembly 320 includes at least one stop for defining the rotation angle of the terminal gripper 330.

[0100] In this embodiment, two stops (not shown in the figure) are preferably provided, which are fixed at the starting and ending points of the rotation of the rotating block 322, respectively, to form a physical limit. When the rotating block 322 rotates, it stops moving when it touches the stop, which strictly limits the rotation amplitude of the terminal gripper 330. The two stops accurately define the starting and ending points of the rotation, eliminating angular deviation.

[0101] As a result, by using both physical stops and position sensors to limit the rotation, the rotation angle is guaranteed to be accurate from both electrical and mechanical perspectives. This dual protection prevents uncontrolled rotation and further improves the accuracy of the pre-installed terminal angle, ensuring stable and reliable installation quality.

[0102] Optionally, based on the rotation and drive structure, the specific structure of the terminal gripper 330 is optimized as follows:

[0103] like Figure 13 and Figure 14 As shown, the terminal gripper 330 includes a gripper structure 331 and a pre-compression structure 332. The gripper structure 331 includes two gripping hook elements 331-1 that clamp together, and the pre-compression structure 332 is disposed between the two gripping hook elements 331-1.

[0104] In this embodiment, the feeding machine places the P-side terminal 11 or the Q-side terminal 12 into the placement slot 340. To facilitate gripping, a gap exists between the placement slot 340 and the terminal, which can easily lead to terminal misalignment. Before the two gripping hook elements 331-1 of the gripper structure 331 symmetrically grip the terminal, as... Figure 14 As shown, the pre-compression structure 332 first presses down on the upper end of the terminal, using external force to correct the tilted terminal to an upright state, eliminating the posture deviation caused by the gap, and ensuring that the gripping hook element 331-1 accurately clamps the center part of the terminal.

[0105] As a result, the pre-pressure structure 332 corrects the terminal posture in advance, avoiding the impact of skewed terminals on the gripping and pre-assembly accuracy, improving the stability of terminal gripping from the source, eliminating problems such as pre-assembly failure and hole damage caused by terminal skew, greatly reducing the defect rate and ensuring processing quality.

[0106] It should be noted that the pre-compression structure 332 can adopt an elastic compression method, and the preferred scheme is as follows: Figure 14 As shown, the pre-compression structure 332 includes a first elastic element 332-1 and a supporting element 332-2. The first elastic element 332-1 abuts against the supporting element 332-2 and outputs a relaxing tension to the supporting element 332-2. The supporting element 332-2 is used to support the end of the P-side terminal 11 or the Q-side terminal 12. The first elastic element 332-1 is preferably a compression spring, and the supporting element 332-2 is a rigid pressure block. The upper end of the first elastic element 332-1 is fixed, and the lower end abuts against the supporting element 332-2. In its natural state, the first elastic element 332-1 outputs a downward relaxing tension to the supporting element 332-2. When the terminal gripper 330 moves downward, the supporting element 332-2 first contacts the upper end of the terminal, and the first elastic element 332-1 is compressed by force. Through the relaxing tension, the terminal is flexibly compressed, correcting its posture while avoiding rigid compression damage to the terminal. After correction, the gripping hook element 331-1 completes the clamping.

[0107] In this embodiment, the elastic pressure method is a flexible correction, with a gentle and controllable force. It can effectively correct the terminal posture without damaging the terminal's appearance and structure, ensuring the terminal's integrity. The first elastic element 332-1 adaptively compensates for the terminal's height deviation, adapting to the pre-pressure correction of terminals of different specifications. It has strong versatility, a simple and reliable structure, and requires no additional power drive.

[0108] It should be noted that the clamping mechanism provided in this application embodiment is used to install the motor cover 10 after the terminal pre-installation mechanism has been pre-installed. As mentioned above, the PQ side terminal assembly machine provided in this application embodiment has two symmetrical sets of terminal pre-installation mechanisms (first terminal pre-installation mechanism 04-1 and second terminal pre-installation mechanism 04-2). Therefore, this application also adaptably provides two sets of clamping mechanisms (first clamping mechanism 05-1 and second clamping mechanism 05-2) to clamp the terminals pre-installed by the two sets of terminal pre-installation mechanisms respectively.

[0109] For ease of understanding, the following explanation will only take one set of clamping mechanisms (first clamping station 05-1) as an example. The structure of the other set of clamping mechanisms (second clamping mechanism 05-2) is exactly the same, and will not be described in detail here.

[0110] like Figures 15 to 16 As shown, the clamping mechanism provided in this embodiment of the application is used for assembling and clamping the P-side terminal 11 and Q-side terminal 12 of the motor cover 10. It includes: a clamping assembly 400, which is used to press the P-side terminal 11 or Q-side terminal 12 pre-installed on the motor cover 10 to clamp the P-side terminal 11 or Q-side terminal 12 onto the motor cover 10; a second drive assembly 600, which is used to drive the clamping assembly 400 to move up and down to clamp the P-side terminal 11 or Q-side terminal 12; and a switching assembly 500. The switching component 500 is disposed between the clamping component 400 and the second drive component 600, and the switching component 500 is connected to the clamping component 400 and the second drive component 600 respectively; the switching component 500 is used to drive the clamping component 400 to move between the third position and the fourth position; when the clamping component 400 is in the third position, the clamping component 400 is facing one of the P-side terminal 11 or the Q-side terminal 12; when the clamping component 400 is in the fourth position, the clamping component 400 is facing the other of the P-side terminal 11 or the Q-side terminal 12.

[0111] In this embodiment, the second drive assembly 600 provides vertical power to drive the clamping assembly 400 to reciprocate up and down. When the clamping assembly 400 moves downward, it directly acts on the P-side terminal 11 or Q-side terminal 12 pre-installed on the motor cover 10, pressing the terminal from the pre-insertion state to the fully fixed state. Since the P-side terminal 11 and Q-side terminal 12 are arranged in a left-right mirror symmetrical manner, their installation positions on the motor cover 10 are laterally offset. Therefore, a switching assembly 500 is provided to drive the clamping assembly 400 to move laterally between the third and fourth points. When processing the cover of the P-side terminal 11, the switching assembly 500 adjusts the clamping assembly 400 to the third point, so that the clamping part is facing the P-side terminal 11. When processing the cover of the Q-side terminal 12, the switching assembly 500 adjusts the clamping assembly 400 to the fourth point, so that the clamping part is facing the Q-side terminal 12. By switching the lateral position, a single clamping mechanism can be compatible with the clamping operations of two symmetrical terminals, eliminating the need for separate equipment and production lines.

[0112] This application embodiment achieves rapid switching of the clamping component 400 position by switching component 500, breaking the limitation of traditional methods that require two sets of clamping mechanisms to process the P and Q side terminals 12 separately. One set of mechanisms can complete the clamping process of two types of terminals, effectively reducing equipment investment, mold occupation and production line footprint, and simplifying production layout. At the same time, it eliminates the tooling replacement and equipment debugging steps when switching models, and completes the model change with one click, improving production continuity and processing efficiency, fundamentally solving the technical problems of poor versatility, high cost and cumbersome process of traditional processing methods.

[0113] Preferably, the switching component 500 includes the following structure.

[0114] The switching component 500 includes a second driving member and a second limiting member, wherein the second limiting member is used to limit the movement of the pressing component 400 along a preset trajectory between the third point and the fourth point; the second driving member is connected to the pressing component 400 and is used to drive the pressing component 400 to reciprocate under the limitation of the limiting member.

[0115] In this embodiment, for the processing scenario where the P-side terminal 11 and the Q-side terminal 12 are laterally offset, the second limiting member restricts the clamping assembly 400 to move only along a horizontal preset trajectory, constrains the direction of movement to avoid offset, and ensures that the clamping assembly 400 is accurately positioned directly above the corresponding terminal; the second driving member provides stable lateral power to the clamping assembly 400, driving it to reciprocate smoothly under the constraint of the second limiting member, thereby achieving stable switching between the third and fourth points.

[0116] This structure, through the coordination of limit and drive, ensures accurate positioning of the 400-type clamping component, stable and reliable movement, and a simple and compact structure. It is suitable for integrated installation in automated production lines, effectively improving the operating accuracy and service life of the mechanism.

[0117] The specific implementation of the switching component 500 can be flexibly selected according to processing requirements. Preferred embodiments are provided in this application as follows:

[0118] Example 1

[0119] like Figure 15 As shown, the second limiting member includes a horizontally arranged third slide rail 510, and the pressing assembly 400 is slidably connected to the third slide rail 510; the second driving member includes a first motor or a first cylinder, and the first motor or the first cylinder is connected to the pressing assembly 400.

[0120] In this embodiment, the third slide rail 510 is arranged horizontally, consistent with the offset direction of the P and Q side terminals 12. The bottom of the clamping assembly 400 slides in conjunction with the third slide rail 510 to achieve horizontal guiding movement. The second driving component is preferably a first cylinder. Position stops are provided at both ends of the third slide rail 510, corresponding to the third and fourth positions respectively. After the first cylinder is activated, it drives the clamping assembly 400 to slide along the third slide rail 510. The movement stops when it touches the stop, achieving precise positioning.

[0121] The slide rail guide structure has a strong load-bearing capacity and can stably support the clamping assembly 400 with multiple components, avoiding movement deviation caused by the weight of the components; the horizontal slide rail has a small movement range and precise guidance, which can effectively prevent the clamping assembly 400 from interfering with surrounding components during the sliding process, and is suitable for heavy-duty and high-frequency clamping operations; the cylinder and stop block method reduces equipment costs while ensuring the accuracy of point switching and meeting the needs of mass production.

[0122] Example 2

[0123] In this embodiment, the second limiting member includes a second connecting rod assembly, which is connected to the pressing assembly 400 to guide the movement trajectory of the pressing assembly 400 between the third and fourth points; the second driving member includes a first motor or a first cylinder, which is connected to the pressing assembly 400.

[0124] In this embodiment, the second connecting rod sub-assembly is composed of multiple hinged connecting rods, one end of which is fixed, and the other end is hinged to the clamping assembly 400. The second driving member drives the connecting rod assembly to extend and swing, causing the clamping assembly 400 to move along a preset trajectory between the third and fourth points. The connecting rod transmission structure is compact, occupies little space, has a fast motion response speed, and has no sliding friction resistance.

[0125] The linkage assembly features rapid switching action and low motion inertia, making it suitable for quick changeover scenarios in lightweight clamping assembly 400. It can match high-speed processing cycles, improve the overall operating efficiency of the equipment, and is suitable for production line layouts with compact space and high requirements for changeover speed.

[0126] Example 3

[0127] In this embodiment, the second limiting member includes a rotating sub-assembly, which is connected to the pressing assembly 400; the second limiting member is used to drive the pressing assembly 400 to rotate in a rotation cycle of 180°, so as to guide the pressing assembly 400 to rotate and change position between the third point and the fourth point; the second driving member includes a first motor or a first cylinder, which is used to drive the rotating sub-assembly to rotate.

[0128] In this embodiment, the rotating sub-assembly adopts a rotating shaft structure, with the clamping assembly 400 fixed to the end of the rotating shaft. The second driving component drives the rotating shaft to rotate 180° periodically, causing the clamping assembly 400 to rotate and reposition, aligning with the third and fourth points respectively. The rotational motion trajectory is stable, with no lateral sliding gap, and high positioning consistency.

[0129] The rotary repositioning method is simple to operate and precise in positioning. It does not require long-distance horizontal movement, effectively saving the horizontal space of the equipment. It is suitable for rapid switching of symmetrical points. After rotating into place, it has good self-locking properties, which prevents displacement during pressing operations and improves pressing stability.

[0130] The above describes the specific switching method of the switching component 500. The following is a more detailed description of the specific working method of the clamping component 400.

[0131] like Figure 16 and Figure 17As shown, the clamping assembly 400 includes a second elastic member 410 and a first clamping member 420. The second elastic member 410 abuts against the first clamping member 420 and outputs tension to the first clamping member 420. The first clamping member 420 is used to hold and clamp the end of the P-side terminal 11 or the Q-side terminal 12.

[0132] In this embodiment, the second elastic element 410 is preferably a compression spring, and the first pressing element 420 is a rigid pressure head. The upper end of the second elastic element 410 is fixed, and the lower end abuts against the first pressing element 420. In its natural state, it outputs downward tension to the first pressing element 420. The second driving assembly 600 drives the pressing assembly 400 downward. After the first pressing element 420 contacts the end of the terminal, the second elastic element 410 is compressed by force, and the P-side terminal 11 or Q-side terminal 12 is smoothly pressed into the motor cover 10 through the elastic tension.

[0133] The elastic pressure application method does not require precise control of the downward pressure of the second drive component 600. The clamping component 400 is driven to move down to the preset position by the second drive component 600, and the clamping force can be controlled by the compression of the second elastic element 410, which reduces the control precision requirements of the drive mechanism. There is no need to use a high-cost servo motor. Precise and stable clamping operation can be achieved by using only ordinary cylinders, which greatly reduces equipment costs and control difficulty.

[0134] Furthermore, the clamping assembly 400 may also include the following structure.

[0135] The clamping assembly 400 includes a pressure sensor 430, which is used to detect the pressure value of the clamping assembly 400 clamping the P-side terminal 11 or the Q-side terminal 12.

[0136] In this embodiment, during the clamping operation, the pressure sensor 430 collects the pressure value of the second elastic element 410 in real time and compares it with the preset standard pressure value. If the measured pressure value deviates from the preset range, it indicates that there is an installation abnormality such as pressure deviation, skewness, or jamming at the terminal, resulting in uneven force. The clamping mechanism uploads this abnormal signal to the control system, marking the motor cover 10 as a defective product, which is automatically rejected when the product flows to the defective material discharge station 07.

[0137] This solution enables simultaneous pressing and inspection, allowing for direct quality assessment of the pressing process without the need for separate inspection stations and equipment. This simplifies the process and improves efficiency. Simultaneously, it monitors the pressing quality in real time, promptly identifying defective products and preventing them from flowing into subsequent processes, thus reducing overall production costs.

[0138] It should be noted that, before the clamping assembly 400 clamps the P-side terminal 11 or the Q-side terminal 12, in order to further ensure the stability of the motor cover 10 and thus improve the success rate of clamping, the following solution is provided.

[0139] like Figures 15 to 17 As shown, it also includes a positioning component 700, which is elastically disposed at the lower end of the clamping component 400; the positioning component 700 is used to clamp and position the motor cover 10 before the clamping component 400 contacts the P-side terminal 11 or the Q-side terminal 12.

[0140] In this embodiment, during the specific working process, the second driving component 600 drives the pressing component 400 and the positioning component 700 to move down synchronously. Because the positioning component 700 is elastically set at the lower end of the pressing component 400, the positioning component 700 first contacts the surface of the motor cover 10, and under the elastic force, it continuously presses and fixes the motor cover 10, eliminating the shaking and floating problems of the motor cover 10. After the motor cover 10 is completely positioned, the pressing component 400 continues to move down to complete the terminal pressing.

[0141] As a result, the positioning component 700 relies on the power of the original second drive component 600 to achieve pre-positioning, without the need for an additional positioning power mechanism. The product can be fixed before pressing using only the elastic structure, which simplifies the structure and reduces costs. It effectively prevents the motor cover 10 from shifting during the pressing process, and greatly improves the terminal pressing accuracy and pass rate.

[0142] The specific structure of the positioning component 700 is not limited in this application embodiment. For ease of understanding, preferred embodiments are provided as follows.

[0143] like Figures 15 to 17 As shown, the positioning component 700 includes a positioning block 710, a positioning slide rail 730, and a third elastic member 720. The positioning slide rail 730 is fixedly connected to the clamping component 400, and the positioning block 710 is slidably connected to the positioning slide rail 730. One end of the third elastic member 720 is connected to the positioning block 710, and the other end is connected to the clamping component 400 or the second drive component 600. The third elastic member 720 outputs tension to the positioning block 710. The positioning block 710 includes a U-shaped pressure plate. The two pressure arms 711 of the U-shaped pressure plate are used to press the positioning motor cover 10 while avoiding the clamping component 400.

[0144] In this embodiment, the positioning slide rail 730 is vertically fixed below the clamping assembly 400, the positioning block 710 slides with the positioning slide rail 730, and the third elastic element 720 provides a downward elastic force to the positioning block 710; the two pressure arms 711 of the U-shaped pressure plate symmetrically press the two sides of the motor cover 10, with a clearance space reserved in the middle to ensure that the first clamping element 420 can smoothly pass through the U-shaped area to contact the terminal. When moving downward, the U-shaped pressure plate first contacts and presses the motor cover 10, the positioning block 710 slides upward along the positioning slide rail 730, the third elastic element 720 is compressed, and the clamping force is maintained continuously; after the clamping is completed, the second drive assembly 600 moves upward, and the third elastic element 720 pushes the positioning block 710 to reset.

[0145] As a result, the U-shaped pressure plate achieves symmetrical positioning on both sides, ensuring stable positioning without deviation, while perfectly avoiding the pressing path and ensuring smooth pressing operation; the combination of sliding fit and elastic pressure makes the positioning action gentle, avoiding damage to the appearance and structure of the motor cover 10, and the positioning and reset response is rapid, making it suitable for automated continuous production.

[0146] The specific working method of the positioning component 700 has been described in detail above. As for the second driving component 600, it is sufficient to drive the positioning component 700 and the pressing component 400 to move up and down. The specific implementation method is not limited in this application. For ease of understanding, the preferred embodiments are provided as follows.

[0147] like Figure 16 and Figure 17 As shown, the driving mechanism includes a second power unit 610, a second slider 630, and a vertically arranged fourth slide rail 620. The fourth slide rail 620 is vertically fixed, the second slider 630 is slidably connected to the fourth slide rail 620, and the clamping assembly 400 is fixedly connected to the second slider 630. The second power unit 610 is connected to the second slider 630 and is used to drive the second slider 630 to move up and down.

[0148] In this embodiment, the fourth slide rail 620 is vertically fixed to the equipment frame, and the second slider 630 slides up and down along the fourth slide rail 620, driving the pressing component 400 and the positioning component 700 to move synchronously; the second power unit 610 is preferably a common cylinder, and the cylinder piston rod is connected to the second slider 630 to drive the second slider 630 to perform vertical reciprocating motion.

[0149] The second slider 630 of the vertical slide rail has high guiding accuracy and smooth, wobbly movement, ensuring precise clamping and positioning. Combined with the aforementioned scheme, the clamping force is controlled by the second elastic element 410, and the positioning is achieved by the third elastic element 720. It eliminates the need for high-cost components such as servo motors and ball screws. Only one set of ordinary cylinders is needed to complete the three processes of product positioning, terminal clamping, and press-fit testing. The structure is simple, the operation is reliable, and the cost is low, which greatly reduces equipment investment and maintenance costs and is suitable for large-scale industrial production.

[0150] The height detection mechanism 06 provided in this embodiment is used for detecting the P-side terminal 11 and Q-side terminal 12 of the motor cover 10 after assembly. It includes: a third drive assembly 800, a pre-pressure assembly 900, a conduction assembly 1000, and a displacement sensor 1100.

[0151] The third drive assembly 800 is connected to the preload assembly 900, and the third drive assembly 800 is used to drive the preload assembly 900 to approach the motor cover 10;

[0152] The transmission component 1000 is slidably connected to the preload component 900, and the transmission component 1000 is signal connected to the displacement sensor 1100; the relative positions of the preload component 900 and the displacement sensor 1100 are fixed.

[0153] During the process of the third drive assembly 800 driving the pre-pressure assembly 900 to approach the motor cover 10, the transmission assembly 1000 first contacts and presses the top of the P-side terminal 11 or the Q-side terminal 12; the third drive assembly 800 continues to drive the pre-pressure assembly 900 and the displacement sensor 1100 to approach the motor cover 10 until the pre-pressure assembly 900 abuts against the motor cover 10; the displacement sensor 1100 detects the displacement of the transmission assembly 1000 relative to the pre-pressure assembly 900, and determines the height of the P-side terminal 11 or the Q-side terminal 12 on the motor cover 10 based on the displacement.

[0154] In this embodiment, the working principle of the above technical solution is explained in detail with the motor cover 10 lying flat and the P-side terminal 11 or Q-side terminal 12 facing vertically upwards. In practical applications, the relative position of the detection mechanism and the motor cover 10 terminal can be adjusted to any direction according to the production line layout. The overall detection process is divided into four steps:

[0155] S1, such as Figure 18 and Figure 19 As shown, the third drive assembly 800 starts and drives the pre-pressure assembly 900 to press down vertically towards the motor cover 10. Since the displacement sensor 1100 and the pre-pressure assembly 900 are connected in a fixed relative position, and the conduction assembly 1000 and the pre-pressure assembly 900 are slidably connected, when the third drive assembly 800 drives the pre-pressure assembly 900 to press down, the displacement sensor 1100 and the conduction assembly 1000 move down synchronously with the pre-pressure assembly 900, and the three of them remain relatively stationary as they approach the motor cover 10.

[0156] S2, such as Figure 20 and Figure 21 As shown, during the process of the pre-pressing component 900, the transmission component 1000 and the displacement sensor 1100 pressing down together, because the detection end of the transmission component 1000 is directly opposite to the P-side terminal 11 or Q-side terminal 12 on the motor cover 10, and the P-side terminal 11 or Q-side terminal 12 protrudes vertically upward on the surface of the motor cover 10, the transmission component 1000 will first contact and press the top of the P-side terminal 11 or Q-side terminal 12. At this time, the terminal forms an upward supporting force on the transmission component 1000, and the transmission component 1000 is held down by the P-side terminal 11 or Q-side terminal 12 and stops moving downward.

[0157] S3, such as Figure 20 and Figure 21As shown, since the conduction component 1000 and the preload component 900 are in a sliding connection, when the conduction component 1000 is held stationary by the P-side terminal 11 or the Q-side terminal 12, the preload component 900 and the displacement sensor 1100 can continue to press down under the continuous driving force of the third drive component 800. At this time, the preload component 900 slides relative to the conduction component 1000, and the preload component 900 moves away from the conduction component 1000 vertically downward. During this sliding process, the relative position of the displacement sensor 1100 and the preload component 900 remains fixed. Therefore, while the preload component 900 moves away from the conduction component 1000, the displacement sensor 1100 also moves relative to the conduction component 1000. The displacement sensor 1100 records the relative displacement in real time during this process.

[0158] S4, such as Figure 22 and Figure 23 As shown, when the lower end face of the pre-pressure component 900 abuts against the upper end face of the motor cover 10, the motor cover 10 provides rigid support to the pre-pressure component 900, and the third drive component 800 stops outputting driving force and terminates its movement. At this time, the pre-pressure component 900 stably abuts against the upper surface of the motor cover 10, and the conduction component 1000 stably abuts against the top surface of the P-side terminal 11 or the Q-side terminal 12. The vertical distance between the upper surface of the motor cover 10 and the top surface of the terminal is the actual installation height of the P-side terminal 11 or the Q-side terminal 12. This installation height is equal to the relative displacement of the pre-pressure component 900 relative to the conduction component 1000. This relative displacement has been completely recorded by the displacement sensor 1100. The displacement sensor 1100 can directly output the height detection result of the P-side terminal 11 or the Q-side terminal 12 on the motor cover 10 based on the recorded relative displacement.

[0159] Therefore, the technical solution of this application, through the ingenious cooperation between the third drive component 800 and the transmission component 1000, and with the help of the displacement sensor 1100, a conventional testing device, can accurately measure the installation height of the P-side terminal 11 or Q-side terminal 12 of the motor cover 10, realizing rapid detection of whether the terminal installation is qualified. It has multiple beneficial effects: 1. The third drive component 800, displacement sensor 1100, etc. used in the testing mechanism are all conventional industrial components, the overall structure of the equipment is simple, and the cost of equipment research and development and procurement is greatly reduced; 2. The components of the mechanism are compactly coordinated and highly integrated, and can be integrated as an independent testing unit in the production line of the motor cover 10 PQ-side terminal assembly equipment, without occupying separate production line space, and can efficiently realize the terminal height detection function within the limited production line layout space; 3. The entire testing process can be completed by only one pressing action of the third drive component 800, without the need for multiple adjustments or testing operations, resulting in high testing efficiency, and the rigid cooperation of the mechanical structure ensures the speed and accuracy of the testing results.

[0160] It should be noted that the specific structures of the third drive component 800, the pre-pressure component 900, the conduction component 1000 and the displacement sensor 1100, as well as the implementation of the relative connection relationship between each component, are not limited in the embodiments of this application. For ease of understanding, preferred embodiments are provided as follows.

[0161] First, the sliding connection between the conduction component 1000 and the preload component 900 can be achieved in various ways, with the preferred method being... Figures 18 to 23 As shown, the conductive component 1000 and the preload component 900 are slidably connected as follows:

[0162] The pre-compression component 900 is provided with a fifth slide rail 910, and the transmission component 1000 is provided on the fifth slide rail 910;

[0163] When the transmission component 1000 contacts and presses the top of the P-side terminal 11 or the Q-side terminal 12, the transmission component 1000 remains stationary, and the fifth slide rail 910 slides relative to the transmission component 1000 so that the pre-pressure component 900 continues to approach the motor cover 10 under the drive of the third drive component 800.

[0164] In this embodiment, in the aforementioned step S3, the transmission component 1000 is held stationary by the P-side terminal 11 or the Q-side terminal 12, while the fifth slide rail 910 and the pre-pressure component 900 are a fixedly connected integrated structure. The transmission component 1000 and the fifth slide rail 910 are in sliding engagement. Therefore, when the third drive component 800 continues to drive the pre-pressure component 900 to press down, the fifth slide rail 910, which is fixed to the pre-pressure component 900, will slide relative to the transmission component 1000 along the sliding direction of the transmission component 1000. This will cause the pre-pressure component 900 and the displacement sensor 1100, which is fixed to the pre-pressure component 900, to continue to press down until the pre-pressure component 900 abuts against the motor cover 10. This sliding engagement method realizes the relative movement between the transmission component 1000 and the pre-pressure component 900 through a simple slide rail structure, ensuring the smooth progress of the detection process.

[0165] Therefore, the sliding connection between the transmission component 1000 and the pre-compression component 900 achieved through the fifth slide rail 910 has significant advantages: Firstly, the slide rail is a standardized mechanical mating structure with low sliding resistance, ensuring smooth sliding of the pre-compression component 900 relative to the transmission component 1000, avoiding detection errors caused by jamming, and improving the stability of the detection process; secondly, the slide rail is easy to install and debug, and the stroke and mating accuracy of the slide rail can be adjusted according to actual detection needs, adapting to different specifications of motor covers 10 and terminal detection scenarios; at the same time, the slide rail structure has a long service life and low maintenance costs, and can adapt to the continuous operation requirements of industrial production lines.

[0166] The preferred embodiment of the pre-compression component 900 is described below.

[0167] It is important to emphasize that the pre-pressure component 900, as the core actuator of the testing mechanism, mainly needs to possess two core functions: 1. It must be able to avoid the P-side terminal 11 or Q-side terminal 12, ensuring that after the transmission component 1000 smoothly abuts against the top of the P-side terminal 11 or Q-side terminal 12, the pre-pressure component 900 can continue to slide relative to the transmission component 1000 without being obstructed by the terminal; 2. When the third drive component 800 drives the pre-pressure component 900 to move to the plane where the motor cover 10 is located, the pre-pressure component 900 can achieve stable surface contact with the motor cover 10, providing a clear trigger point for the stopping movement of the third drive component 800 and ensuring that the reference plane is consistent for each test. Based on these two functional requirements, the contact element between the pre-pressure component 900 and the motor cover 10 can be set to different structures such as needle-shaped, block-shaped, or plate-shaped according to the testing requirements. This application embodiment is not limited in this regard. For ease of understanding, a preferred embodiment is provided as follows.

[0168] like Figures 18 to 23 As shown, the pre-compression assembly 900 includes a pre-compression plate 920 and a mounting plate 930, wherein,

[0169] There are two mounting plates 930, which are respectively located at both ends of the pre-pressing plate 920. One end of each mounting plate 930 is connected to the pre-pressing plate 920, and the other end is connected to the third drive assembly 800. The fifth slide rail 910 is located on the mounting plate 930.

[0170] The preload plate 920 has a clearance hole 921, which is used to avoid the P-side terminal 11 or the Q-side terminal 12, so that the conductive assembly 1000 can contact and press the top of the P-side terminal 11 or the Q-side terminal 12 through the clearance hole 921.

[0171] In this embodiment, two mounting plates 930 are respectively vertically fixed at both ends of the pre-pressure plate 920, forming a "door" shaped overall structure. The fifth slide rail 910 is vertically disposed on the inner side wall of the mounting plate 930. The two ends of the transmission component 1000 are slidably engaged with the fifth slide rail 910 on the two mounting plates 930. Thus, the two mounting plates 930 together limit the sliding space and sliding direction of the transmission component 1000 relative to the pre-pressure component 900 through the fifth slide rail 910. This ensures that after the transmission component 1000 abuts against the top surface of the P-side terminal 11 or the Q-side terminal 12, it can only slide vertically relative to the pre-pressure component 900 along the extension direction of the fifth slide rail 910, avoiding detection errors caused by horizontal displacement of the transmission component 1000.

[0172] Furthermore, the contact element in the pre-pressure assembly 900 that abuts against the motor cover 10 is a plate-shaped pre-pressure plate 920. The plate-shaped structure can form a large-area surface contact with the upper surface of the motor cover 10, ensuring stability during contact and preventing the pre-pressure assembly 900 from tilting due to point or line contact, thereby improving the overall stability of the detection system. At the same time, the pre-pressure plate 920 has a clearance hole 921 at the position corresponding to the P-side terminal 11 or the Q-side terminal 12. The diameter of the clearance hole 921 is larger than the outer diameter of the terminal, achieving complete clearance of the P-side terminal 11 or the Q-side terminal 12. This ensures that the conductive assembly 1000 can pass through the clearance hole 921 and contact the top of the terminal, and that the pre-pressure plate 920 can clear the P-side terminal 11 or the Q-side terminal 12. Thus, after the conductive assembly 1000 abuts against the P-side terminal 11 or the Q-side terminal 12, the pre-pressure assembly 900 can continue to slide downward in the vertical direction without being blocked by the terminal.

[0173] Therefore, the pre-compression assembly 900 structure in this embodiment has significant advantages: First, both the pre-compression plate 920 and the mounting plate 930 are sheet metal or machined parts, with simple structure, low processing and manufacturing costs, and the connection between the parts is fixed by bolts, making disassembly and maintenance convenient; Second, the fifth slide rail 910 on the two mounting plates 930 cooperates with the transmission assembly 1000 to achieve bidirectional limiting sliding of the transmission assembly 1000, with stable sliding without deviation, ensuring detection accuracy while improving detection efficiency; Third, the large-area contact method of the plate-shaped pre-compression plate 920 combined with the clearance design of the clearance hole 921 ensures the consistency of the detection reference surface and achieves unobstructed contact between the transmission assembly 1000 and the terminal, meeting the dual core functional requirements of the pre-compression assembly 900.

[0174] The preferred embodiment of the displacement sensor 1100 will be described below.

[0175] The displacement sensor 1100 can detect the relative displacement of the conductive component 1000 in various ways, such as infrared ranging, ultrasonic ranging, or contact detection of physical components. This application does not limit the detection method. For ease of understanding, preferred embodiments are provided as follows.

[0176] The signal connection between the transmission component 1000 and the displacement sensor 1100 is as follows:

[0177] A first conductive link 1110 is provided between the conductive component 1000 and the displacement sensor 1100. The first conductive link 1110 is fixedly connected to the conductive component 1000 and slidably connected to the displacement sensor 1100.

[0178] The displacement sensor 1100 determines the displacement of the transmission assembly 1000 relative to the preload assembly 900 by detecting the relative displacement of the first transmission link 1110.

[0179] In this embodiment, as Figures 18 to 23 As shown, the first conductive link 1110 is arranged vertically, with its lower end fixedly connected to the upper end face of the conductive assembly 1000, and its upper end coaxially inserted into the detection end of the displacement sensor 1100, forming a sliding fit with the displacement sensor 1100. Therefore, in step S3 above, when the relative position of the conductive assembly 1000 and the displacement sensor 1100 changes, the first conductive link 1110, fixed to the conductive assembly 1000, will synchronously slide relative to the displacement sensor 1100. The displacement sensor 1100 can detect the sliding displacement of the first conductive link 1110 in real time through its detection end. Since the first conductive link 1110 is fixedly connected to the conductive assembly 1000, this sliding displacement is equal to the displacement of the conductive assembly 1000 relative to the pre-compression assembly 900. Therefore, the displacement sensor 1100 can directly determine the displacement of the conductive assembly 1000 relative to the pre-compression assembly 900 by detecting the relative displacement of the first conductive link 1110.

[0180] As a result, this signal connection and detection method has outstanding advantages: the mechanical connection and displacement transmission between the transmission component 1000 and the displacement sensor 1100 are achieved through the physical first transmission link 1110. Compared with non-contact ranging methods such as infrared and ultrasonic, it is not affected by environmental factors such as dust and light in industrial production lines, and the detection results are more accurate. At the same time, the first transmission link 1110 is a conventional shaft part with a simple structure and low cost. The sliding fit with the displacement sensor 1100 does not require complex circuit debugging. The accurate detection of displacement can be achieved simply through the clever connection relationship of the mechanical structure, which takes into account both the high efficiency and low cost of detection.

[0181] It should be noted that, since the core movement of the entire height detection mechanism 06 is the vertical downward pressing movement of the pre-compression component 900, each component can theoretically reach its proper position at each movement node under the action of gravity. However, factors such as equipment vibration and part fitting clearance exist in industrial production lines, which can easily cause unnecessary small movements of the components, affecting the detection accuracy of the displacement sensor 1100. In order to further ensure the measurement accuracy, this application further provides the following solution.

[0182] like Figures 18 to 23 As shown, a first spring 1120 is sleeved on the first conductive link 1110. One end of the first spring 1120 is fixedly connected to the first conductive link 1110 or the conductive assembly 1000, and the other end of the first spring 1120 is connected to the displacement sensor 1100.

[0183] In this embodiment, the first spring 1120 is coaxially sleeved on the first conductive connecting rod 1110. Simultaneously, the lower end of the first spring 1120 is fixedly connected to the upper end face of the conductive assembly 1000, and the upper end of the first spring 1120 is fixedly connected to the lower end face of the displacement sensor 1100. Initially, the first spring 1120 is in a slightly compressed state, thus continuously generating downward tension between the conductive assembly 1000 and the displacement sensor 1100. When the conductive assembly 1000 contacts and presses the top surface of the P-side terminal 11 or the Q-side terminal 12, the tension of the first spring 1120 continues to act on the conductive assembly 1000, ensuring that the conductive assembly 1000 always tightly abuts against the top surface of the P-side terminal 11 or the Q-side terminal 12. This prevents the conductive assembly 1000 from experiencing slight upward displacement due to relative sliding with the pre-compression assembly 900, equipment vibration, or other factors, and avoids deviations in the detection value of the displacement sensor 1100 caused by gaps between the conductive assembly 1000 and the terminal tops.

[0184] Therefore, by setting the first spring 1120 on the first transmission link 1110, unnecessary movement of each component during the testing process can be effectively avoided, significantly improving the testing accuracy: Firstly, the continuous tension of the first spring 1120 provides a downward preload to the transmission assembly 1000, ensuring that the transmission assembly 1000 is always in contact with the terminal top, eliminating the testing error caused by the gap between the parts; Secondly, the elastic buffering effect of the spring can absorb the equipment vibration in the production line, avoiding the slight shaking of the transmission assembly 1000 caused by vibration, and improving the stability of the testing process; Thirdly, the installation method of the first spring 1120 is simple, and springs with different elastic coefficients can be replaced according to the testing requirements to adapt to the testing requirements of different specifications of terminals, which is highly flexible.

[0185] The preferred embodiment of the conductive component 1000 will be described below.

[0186] It should be emphasized that the conductive component 1000, as a detection component that directly contacts the terminal, can be designed in various ways according to factors such as the specifications and spacing of the terminal. The specific structure of the conductive component 1000 is not limited in the embodiments of this application. For ease of understanding, the preferred embodiments are provided as follows.

[0187] like Figures 18 to 23 As shown, the conductive assembly 1000 includes a conductive plate 1010, a conductive block 1020, a second conductive link 1030, and a second spring 1040, wherein...

[0188] The conductive plate 1010 is T-shaped. The T-shaped conductive plate 1010 includes a vertical arm 1012 and a horizontal arm 1011 that are perpendicular to each other. The horizontal arm 1011 is connected to the conductive block 1020. One side of the vertical arm 1012 is connected to the first conductive link 1110. The other side of the vertical arm 1012 is used to contact and press the top of the P-side terminal 11 or the Q-side terminal 12.

[0189] The conductive block 1020 is slidably connected to the pre-compression component 900. The second conductive link 1030 is parallel to the sliding direction of the conductive block 1020 relative to the pre-compression component 900. The conductive block 1020 and the second spring 1040 are sequentially sleeved on the second conductive link 1030.

[0190] In this embodiment, the longitudinal arm 1012 of the T-shaped conductive plate 1010 is a slender rod-like structure, with its lower end serving as a detection end for contacting the top of the P-side terminal 11 or the Q-side terminal 12. This allows for precise pressure against the delicate terminal structure, avoiding interference between adjacent terminals caused by an excessively wide detection end of the conductive plate 1010. The transverse arm 1011 of the T-shaped conductive plate 1010 is a plate-like structure, with both ends fixedly connected to the conductive blocks 1020 on both sides. This ensures a stable connection between the conductive plate 1010 and the conductive blocks 1020, balancing the precision of terminal contact with the overall sliding stability of the conductive assembly 1000. Preferably, the longitudinal arm 1012 and the transverse arm 1011 of the T-shaped conductive plate 1010 are integrally formed.

[0191] Furthermore, the transmission block 1020 is slidably engaged with the fifth slide rail 910 on the pre-compression assembly 900, and the second transmission link 1030 is arranged in a vertical direction parallel to the extension direction of the fifth slide rail 910. The transmission block 1020 and the second spring 1040 are coaxially sleeved on the second transmission link 1030 in sequence. One end of the second spring 1040 is fixedly connected to the transmission block 1020, and the other end is fixedly connected to the pre-compression assembly 900. In the initial state, the second spring 1040 is in a slightly compressed state. The working principle of this structure is consistent with the cooperation principle of the first transmission link 1110 and the first spring 1120 mentioned above. The second spring 1040 continuously generates downward tension between the transmission block 1020 and the pre-compression component 900. When the longitudinal arm 1012 of the transmission plate 1010 contacts the top of the terminal, the tension of the second spring 1040 is transmitted to the transmission plate 1010 through the transmission block 1020, ensuring that the transmission plate 1010 always tightly abuts the top of the terminal, while limiting the excessive shaking of the transmission block 1020 on the fifth slide rail 910, further avoiding unnecessary movement of the transmission component 1000 and improving detection accuracy.

[0192] The preferred embodiment of the third drive component 800 is described below.

[0193] It should be noted that, since the motor cover 10 is a standardized machined part, the flatness of the upper surface of the standard motor cover 10 parts after testing is consistent. The stroke of the pre-pressure component 900 from the initial position to the upper surface of the motor cover 10 is a fixed value. Therefore, the third drive component 800 only needs to ensure that the pre-pressure component 900 moves by a fixed amplitude each time to achieve the uniformity of the testing benchmark. The specific implementation of the third drive component 800 is not limited in this application embodiment. Preferred embodiments are provided as follows.

[0194] like Figures 18 to 23 As shown, the height detection mechanism 06 also includes a mounting bracket 1200, a third drive component 800 is disposed on the mounting bracket 1200, a sixth slide rail 1210 is provided on the mounting bracket 1200, and a pre-pressure component 900 is slidably connected to the mounting bracket 1200 through the sixth slide rail 1210.

[0195] The third drive assembly 800 includes a height detection cylinder 810, the output shaft of which is connected to the preload assembly 900;

[0196] A magnetic component is provided at a preset position on the output shaft of the height detection cylinder 810, and a magnetic sensor is provided on the mounting bracket 1200. When the height detection cylinder 810 drives the preload component 900 to abut against the motor cover 10, the relative distance between the magnetic component and the magnetic sensor is less than a preset value.

[0197] In this embodiment, the mounting bracket 1200 is the overall support structure of the detection mechanism. The height detection cylinder 810 is vertically fixed at the top of the mounting bracket 1200. The sixth slide rail 1210 is vertically disposed on the inner side wall of the mounting bracket 1200. The pre-pressure component 900 is slidably engaged with the sixth slide rail 1210. The output shaft of the height detection cylinder 810 is vertically downward and fixedly connected to the pre-pressure component 900. After the height detection cylinder 810 is started, the pre-pressure component 900 is driven to reciprocate vertically along the sixth slide rail 1210 through the extension and retraction of the output shaft. A magnetic component is fixed on the output shaft of the height detection cylinder 810 at the position where the preload component 900 abuts against the motor cover 10. A magnetic sensor is installed on the mounting bracket 1200 at the position corresponding to the magnetic component. The magnetic sensor is electrically connected to the control system of the equipment. When the height detection cylinder 810 drives the preload component 900 to press down along the sixth slide rail 1210 until it abuts against the motor cover 10, the magnetic component on the output shaft is also pressed down until the relative distance between it and the magnetic sensor is less than a preset value. The magnetic sensor detects the magnetic field signal of the magnetic component and transmits the signal to the control system. After receiving the signal, the control system controls the height detection cylinder 810 to stop outputting driving force, thus completing one pressing detection action.

[0198] As a result, the design of the third drive component 800 has significant advantages: through the cooperation of magnetic components and magnetic sensors, precise control of the stroke of the height detection cylinder 810 is achieved, enabling the low-cost height detection cylinder 810 to achieve stroke control accuracy similar to that of a servo motor, eliminating the need for a more expensive servo motor as the drive source, thus significantly reducing the cost of the third drive component 800. At the same time, the height detection cylinder 810 has a fast response speed and stable output force, which can meet the continuous operation requirements of industrial production lines. In addition, the sixth slide rail 1210 provides guidance and limit for the movement of the preload component 900, ensuring that the preload component 900 always moves in the vertical direction, avoiding detection reference deviation caused by horizontal offset of the preload component 900, and further improving detection accuracy.

[0199] Optionally, in this embodiment, the installation method in which the relative positions of the pre-compression component 900 and the displacement sensor 1100 are fixed is as follows: the pre-compression component 900 and the displacement sensor 1100 are both fixedly connected to a common slider. The slider is slidably engaged with the sixth slide rail 1210 on the mounting bracket 1200. The output shaft of the height detection cylinder 810 of the third drive component 800 is fixedly connected to the slider. When the output shaft of the height detection cylinder 810 extends or retracts, it drives the slider to slide along the sixth slide rail 1210, thereby driving the pre-compression component 900 and the displacement sensor 1100 to slide synchronously. This achieves synchronous movement with fixed relative positions between the pre-compression component 900 and the displacement sensor 1100, ensuring the consistency of their movements.

[0200] It should be noted that, in the specific working process, since there are two P-side terminals 11 or Q-side terminals 12 installed on the motor cover 10, and the two terminals are symmetrically distributed, in order to accurately detect whether the installation height of a pair of terminals meets the standard, this application adopts the following solution.

[0201] like Figures 18 to 23 As shown, the preload assembly 900 is in one group, and the transmission assembly 1000 and displacement sensor 1100 are in two groups each.

[0202] Two sets of transmission components 1000 and two sets of displacement sensors 1100 are respectively located at both ends of the preload component 900, with each set of transmission components 1000 corresponding to one set of displacement sensors 1100.

[0203] The two sets of conductive components 1000 are respectively aligned with the two P-side terminals 11 or the two Q-side terminals 12 installed on the motor cover 10.

[0204] In this embodiment, two sets of conductive components 1000 are symmetrically arranged at both ends of the pre-compression component 900. Each set of conductive components 1000 is connected to the corresponding displacement sensor 1100 through an independent first conductive link 1110. The detection ends of the two sets of conductive components 1000 are respectively aligned with the two symmetrically distributed P-side terminals 11 or Q-side terminals 12 on the motor cover 10. Combining the aforementioned structural scheme of the conductive component 1000, the conductive plate 1010 in the conductive component 1000 is T-shaped, and its longitudinal arm 1012 is a slender rod structure with a small detection end. Even if the distance between the left and right terminals on the motor cover 10 is small, the longitudinal arms 1012 of the two conductive plates 1010 can accurately abut the top of the corresponding terminals respectively without mutual interference, thereby achieving independent and accurate detection of the two terminals.

[0205] Therefore, the beneficial effects of this solution are as follows: by setting up two sets of one-to-one corresponding transmission components 1000 and displacement sensors 1100, the height detection of the two P-side terminals 11 or Q-side terminals 12 on the motor cover 10 can be completed simultaneously in one pressing detection action, eliminating the need for two separate detections and greatly improving detection efficiency; at the same time, each set of transmission components 1000 and displacement sensors 1100 is an independent detection unit, which can output the height detection results of the two terminals separately, accurately determining whether the installation of a single terminal is qualified, avoiding misjudgment of the entire motor cover 10 due to the unqualified installation of one terminal, and improving the accuracy and reliability of the detection.

[0206] In summary, the motor cap PQ side terminal assembly machine provided in this application aims to solve the problems of low production efficiency, high cost, and poor versatility in the prior art, which requires two independent assembly lines for P-side and Q-side terminals. This assembly machine includes a feeding belt, a turntable, and various workstation mechanisms. The turntable drives the motor caps to be processed through the following stations sequentially: top-extension rotation exchange, visual inspection, terminal pre-assembly, clamping, height detection, and defective material discharge. The terminal pre-assembly mechanism can switch between two positions to pre-assemble either the P-side or Q-side terminals, and the clamping mechanism simultaneously switches positions to complete the clamping. This solution allows one assembly line to adapt to two types of terminal assembly, eliminating the need for separate material preparation, processing, and inspection lines, significantly improving production efficiency, reducing equipment investment, mold management, and material control costs, enhancing product versatility, and ensuring product assembly quality through multi-mechanism inspection.

[0207] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
