Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, specifically relating to a device for pressing diodes onto the positive plate of an automotive alternator rear cover assembly. Background Technology

[0002] The diode press-fitting equipment for the rear cover assembly of an automotive alternator is a key process equipment used to precisely press rectifier diodes into the positive electrode plate of the alternator. Its core function is to achieve a high-precision, high-reliability mechanical connection between the diode and the electrode plate, ensuring the stability of the alternator rectifier system's conversion of AC to DC. The quality of diode press-fitting directly affects the accuracy of the alternator output voltage, rectifier lifespan, and the reliability of the vehicle's electrical system. According to industry statistics, rectifier failures account for 65% to 75% of all alternator failures, with diode failures accounting for as much as 80%. Diode failure not only causes fluctuations in alternator output voltage and triggers vehicle electrical system malfunctions, but in severe cases, it can even cause overcharging or undercharging of the battery, shortening battery life. Therefore, reliable diode press-fitting is a crucial step in ensuring alternator performance. Existing alternator rear cover diode press-fitting uses single-axis hydraulic or pneumatic presses, with multiple diodes being pressed sequentially manually or using simple tooling. Manual press-fitting is inefficient. Utility Model Content

Detailed Implementation

[0024] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0025] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the automotive alternator rear cover assembly diode pressing equipment is used to automatically press diodes onto the front plate. It includes a worktable 1, on which a stepping rotary platform 2 is set. Several equidistantly distributed fixed fixtures 3 are set on the rotary platform 2. A diode loading station 4, a pressing station 5, and a unloading station 6 are arranged around the rotary platform 2. The diode loading station 4 is used to place the diodes in the position to be installed on the front plate. The pressing station 5 is used to press the diodes placed on the front plate. The unloading station 6 is used to remove the front plate with the pressed diodes from the fixed fixtures 3.

[0026] This utility model proposes a diode pressing device for the rear cover assembly of an automotive alternator. The device automatically presses diodes onto the rear cover assembly. The workbench 1 provides a stable platform for the operation of the entire device.

[0027] The rotating platform 2 is set on the worktable 1 and adopts a step-by-step rotation method, that is, it rotates according to a certain step length and rhythm. Several fixed fixtures 3 are set on the rotating platform 2. These fixed fixtures 3 are evenly distributed to fix the plate and ensure the stability of the plate's position during rotation.

[0028] Three workstations are arranged sequentially around the rotating platform 2: diode loading station 4, pressing station 5, and unloading station 6. Each workstation has a specific function and is arranged in a certain order to realize the automated process of diode pressing.

[0029] Before the equipment is started, the rotating platform 2 is in the initial position, and the positive plates of diodes to be installed may have been placed on each of the fixed fixtures 3 (or the positive plates can be placed on the fixed fixtures 3 manually or by an automatic feeding device after the equipment is started).

[0030] The rotating platform 2 rotates in a step-by-step manner. When a certain fixed fixture 3 rotates with the rotating platform 2 to the diode loading station 4, the diode loading station 4 starts to work and accurately places the diode on the mounting position of the plate on the fixed fixture 3.

[0031] After the loading is completed, the rotary platform 2 continues to rotate step by step, moving the positive plate containing the diodes to the pressing station 5. At the pressing station 5, the equipment applies pressure to the diodes placed on the positive plate, firmly pressing them onto the positive plate.

[0032] After pressing is completed, the rotary platform 2 rotates again, moving the pressed diode plate to the unloading station 6. The unloading station 6 removes the pressed diode plate from the fixed fixture 3, thus completing a full diode pressing cycle. The rotary platform 2 then continues to rotate, repeating the above steps to achieve continuous and automated diode pressing production.

[0033] Combination Figure 1 , Figure 2 and Figure 3 As shown, the diode loading station 4 includes a vibratory feeder 41 mounted on the workbench 1, and a material handling robot 42 is mounted at the outlet of the vibratory feeder 41.

[0034] Specifically, the vibratory feeder 41, mounted on the workbench 1, is one of the core components of the diode loading station 4. The vibratory feeder 41 typically has a specific disc structure with an internal spiral track. Regular vibrations generated by a vibrating device at the bottom of the vibratory feeder 41 allow the diodes placed inside the disc to move orderly upwards along the spiral track, eventually reaching the outlet of the vibratory feeder 41. This achieves automatic sorting and conveying of a large number of scattered diodes, providing a stable and orderly source of diodes for subsequent material handling operations.

[0035] The picking robot 42 is located at the outlet of the vibratory feeder 41 and is also fixed on the worktable 1. The picking robot 42 has a flexible motion mechanism, generally composed of a robotic arm, grippers, etc. The robotic arm can achieve multi-degree-of-freedom movement, such as extension, rotation, and lifting, so as to accurately reach the outlet of the vibratory feeder 41 to pick up the diodes; the grippers are designed according to the shape and size of the diodes, and can firmly and accurately clamp the diodes to prevent them from falling or being damaged during transportation.

[0036] Once the equipment is started, a certain number of diodes are poured into the vibratory feeder 41. The vibratory feeder 41 begins to vibrate, and the internal spiral track, under the action of vibration, causes the diodes to gradually move upward along the track. This achieves an orderly arrangement, and they eventually reach the outlet of the vibratory feeder 41 in sequence. At this point, the diodes are in a state of waiting to be picked up.

[0037] The robotic arm 42, controlled by a preset program, moves along a designated path to the outlet of the vibratory feeder 41. Then, under the command of the control system, the gripper opens and accurately catches the diode located at the outlet. The gripper then closes, firmly holding the diode.

[0038] After the robotic arm 42 picks up the diode, it moves again, transporting the diode to its designated position on the board according to a pre-set trajectory. Once at the designated position, the gripper releases, accurately placing the diode on the board, completing the diode loading operation. The robotic arm 42 then returns to its initial position, awaiting the next loading command. This cycle repeats continuously, achieving automatic diode loading.

[0039] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the pressing station 5 includes a fixed frame 51 located behind the diode loading station 4. Two sets of pressing mechanisms 52 for pressing diodes on the positive plate are arranged side by side on the fixed frame 51. The pressing mechanism 52 has a drive mechanism 53 that drives it to move on the XY axis.

[0040] Specifically, the mounting bracket 51 serves as the basic support structure for the entire pressing station 5. It is installed on the workbench 1, located behind the diode loading station 4. The mounting bracket 51 provides a stable mounting platform for the pressing mechanism 52, ensuring that the pressing mechanism 52 will not shake or shift during the pressing process, thereby guaranteeing the accuracy and quality of the pressing.

[0041] Two sets of pressing mechanisms 52 are arranged side-by-side on the fixed frame 51. These two sets of pressing mechanisms 52 can work simultaneously or operate independently according to actual production needs. Each pressing mechanism 52 has specific pressing components, which are usually designed to match the shape of the diode and the positive plate, and can apply uniform and stable pressure to the diode during the pressing process, so that it is accurately embedded in the positive plate.

[0042] The drive mechanism 53 is connected to the pressing mechanism 52, providing the power for the pressing mechanism 52 to move along the XY axis. The drive mechanism 53 typically consists of a high-precision motor, lead screw, guide rail, and other components. The rotation of the motor drives the lead screw to rotate, which in turn causes the nut mating with the lead screw and the pressing mechanism 52 mounted on the nut to move precisely along the guide rail in the XY axis direction. This allows the pressing mechanism 52 to flexibly adjust its position to adapt to the pressing requirements of positive circuit boards and diodes of different specifications and positions.

[0043] When the positive plate is transported to the pressing station 5 by the rotating platform 2, the drive mechanism 53 starts working. According to the preset program and the information fed back by the sensors (such as the position of the positive plate, the position of the diode to be installed, etc.), the motor in the drive mechanism 53 starts, and through the transmission of the lead screw and nut, it drives the pressing mechanism 52 to make initial movement on the XY axis, so that the pressing mechanism 52 is close to the diode to be installed area on the positive plate, and completes the initial positioning.

[0044] After initial positioning, to ensure the accuracy of pressing, the drive mechanism 53 further fine-tunes the position of the pressing mechanism 52. High-precision sensors monitor the relative positional relationship between the pressing mechanism 52 and the diode and positive plate in real time, and feed the data back to the control system. Based on the feedback information, the control system precisely controls the rotation of the motor, causing the pressing mechanism 52 to make minute movements along the XY axes until the optimal pressing position is reached.

[0045] Once the pressing mechanism 52 reaches the correct position, the driving mechanism 53 applies pressure, causing the pressing component of the pressing mechanism 52 to move downwards and press the diode on the positive plate. During the pressing process, the driving mechanism 53 continuously provides stable pressure to ensure that the diode can be firmly embedded in the positive plate, and the magnitude and duration of the pressing force can be precisely controlled according to factors such as the material and specifications of the diode and the positive plate.

[0046] After pressing is completed, the drive mechanism 53 drives the pressing mechanism 52 to move upward and return to the initial position. At the same time, the rotating platform 2 will transport the positive plate that has completed diode pressing away and transport the next positive plate to be pressed to the pressing station 5. At this time, the drive mechanism 53 will start again and repeat the above steps to perform a new round of pressing operations, realizing continuous and efficient diode pressing production.

[0047] Combination Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the pressing mechanism 52 includes a pressing cylinder 521 mounted on a fixed frame 51, and the output end of the pressing cylinder 521 is connected to a pressing block 522.

[0048] Specifically, the pressing cylinder 521 serves as the power source for the pressing mechanism 52, and is mounted on the fixed frame 51. The pressing cylinder 521 is selected and designed according to the pressure and stroke required for diode pressing to ensure that it can provide sufficient and stable pressing force.

[0049] The pressing block 522 is connected to the output end of the pressing cylinder 521. The pressing block 522 is the component that directly contacts the diode and the positive plate. The working surface of the pressing block 522 is machined into a shape that matches the outer contour of the diode to ensure that pressure can be applied evenly during the pressing process and to avoid damage to the diode due to uneven force.

[0050] Combination Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the unloading station 6 includes a mounting frame 61 located behind the pressing station 5. The mounting frame 61 is equipped with an unloading robot 62. The picking end of the unloading robot 62 is connected to a mounting plate 63. The bottom of the mounting plate 63 is connected to a finger cylinder 64. The output end of the finger cylinder 64 is connected to a picking gripper 65.

[0051] Specifically, the mounting frame 61 serves as the basic support structure for the entire unloading station 6. It is installed on the workbench 1 and located behind the pressing station 5. The mounting frame 61 provides a stable mounting platform for the unloading robot 62, ensuring that the unloading robot 62 will not shake or shift during operation, thereby guaranteeing the accuracy and stability of the unloading operation.

[0052] The unloading robot 62, mounted on the mounting frame 61, is the core moving component of the unloading station 6. It typically possesses multi-degree-of-freedom motion capabilities and generally consists of a robotic arm, a drive motor, and a transmission mechanism. The robotic arm can rotate and extend flexibly in multiple directions. Through precise control of the drive motor and transmission mechanism, the robotic arm achieves accurate positioning and movement in three-dimensional space, enabling it to accurately reach above the pressing station 5, grasp the pressed plate, and transport it to the designated location.

[0053] Mounting plate 63 is connected to the picking end of unloading robot 62, serving to connect and support finger cylinder 64. Mounting plate 63 ensures that finger cylinder 64 can be mounted on mounting plate 63 without interfering with the movement of unloading robot 62.

[0054] Finger cylinders 64 are fixed to the bottom of mounting plate 63 and are cylinders that drive the fingers to open and close. Finger cylinders 64 have two or more movable fingers, and by controlling the inlet and outlet of compressed air, the fingers can be opened and closed. The selection and design are based on the size and shape of the plate to ensure stable and reliable gripping.

[0055] The gripper 65 is connected to the output end of the finger cylinder 64 and is the component that directly contacts the plate. The shape and size of the gripper 65 are carefully designed according to the specific structure of the plate, and it usually adopts a shape that matches the outer contour of the plate to increase the gripping contact area and stability.

[0056] Once the material unloading station 6 receives the unloading signal, the unloading robot 62 begins to work. The drive motor of the unloading robot 62 starts, and through the transmission mechanism, it drives the robotic arm to move, so that the picking end of the unloading robot 62 moves to the initial positioning position above the pressing station 5.

[0057] After the unloading robot 62 reaches its initial positioning position, the finger cylinder 64 begins to move. The unloading robot 62 continues to fine-tune its position so that the opening gripper 65 accurately aligns with the pressed plate. Then, the gripper 65 clamps the plate. During this process, the finger cylinder 64 provides sufficient clamping force to ensure that the plate does not fall during handling.

[0058] Once the plate is gripped by the material handling gripper 65, the drive motor of the unloading robot 62 starts again, driving the robot arm to transport the plate from the pressing station 5 to the designated unloading position according to the preset path.

[0059] After the unloading robot 62 moves the plate to the designated position, the picking gripper 65 releases the plate and places it in the designated position. Then, the unloading robot 62 drives the mounting plate 63, the finger cylinder 64, and the picking gripper 65 back to the initial position, waiting for the next unloading command, thus completing one complete unloading cycle.

[0060] Combination Figure 1 , Figure 2 and Figure 8 As shown, the rotating platform 2 includes a rotating cylinder 21 located at the center of the workbench 1. The output end of the rotating cylinder 21 is connected to a rotating disk 22. A rotating seat 23 is located at the center of the rotating disk 22. Several fixed columns 24 are evenly distributed on the rotating seat 23. Each fixed column 24 is equipped with a position sensor 25.

[0061] Specifically, the rotary cylinder 21 serves as the power source for the rotary platform 2, and is installed at the center of the worktable 1. The rotary disk 22 is tightly connected to the output end of the rotary cylinder 21 and is the main load-bearing component of the rotary platform 2. The rotary disk 22 is circular, and its diameter is designed according to the workpiece size and operating space. When the rotary cylinder 21 operates, the rotary disk 22 rotates together with the output end of the rotary cylinder 21, providing rotational support for the workpiece placed on it.

[0062] The rotating base 23 is positioned at the center of the rotating disk 22, serving to stabilize and position the device. The rotating base 23 provides a stable mounting foundation for the fixed posts 24, allowing the fixed posts 24 to be accurately distributed on the rotating disk 22.

[0063] Fixed columns 24 are equidistantly distributed on the rotating base 23, with the number determined according to actual production needs. The fixed columns 24 are used to fix the workpieces, and their shape and size are designed according to the type of workpiece and the fixing method. Each fixed column 24 is equipped with a position sensor 25 to detect whether the orientation of the plate on the rotating disk 22 corresponds to the diode loading station 4, pressing station 5, and unloading station 6. The position sensor 25 can be of various types, such as photoelectric sensors and proximity sensors, and can provide real-time feedback of the workpiece's position information to the control system. This allows the control system to control the rotation of the rotating platform 2 and the operation of other related equipment based on the workpiece's position status, ensuring the accuracy and stability of the production process.

[0064] Combination Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the fixing fixture 3 includes a fixture seat 31 disposed on the rotating disk 22, and a positioning pin 32 is disposed on the top of the fixture seat 31.

[0065] Specifically, the fixture base 31 is the basic support component for fixing the fixture 3, and it is set on the rotating disk 22. The shape and size of the fixture base 31 are designed according to the shape and size of the workpiece and the spatial layout of the rotating disk 22. Common shapes include square and round. Its surface is generally finely machined to ensure the fitting accuracy with the workpiece and the positioning pin 32.

[0066] The locating pin 32 is located on the top of the fixture base 31 and is the core component for fixing the fixture 3 to achieve precise workpiece positioning. The locating pin 32 is generally cylindrical, and its diameter and length are precisely designed according to the size of the locating hole on the workpiece. It is usually manufactured using high-precision machining technology to ensure that the fit clearance with the workpiece locating hole is within a reasonable range, which can ensure both smooth installation of the workpiece and precise positioning.

[0067] Combination Figure 1 , Figure 2 and Figure 3 As shown, a control switch 7 is installed on the workbench 1.

[0068] Specifically, control switch 7 is located on workbench 1. Common operating components of control switch 7 include buttons, knobs, and levers. Buttons are typically used to perform simple switching actions, such as starting and stopping the equipment; knobs can be used to adjust equipment parameters, such as speed and temperature; levers are often used to switch the equipment's operating mode or state. Operating components are generally mounted on the surface of the housing and are clearly marked for easy identification and operation by the operator. For example, the start button may be marked in green, and the stop button in red.

[0069] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
