Description

Technical Field

[0001] This application relates to the field of press-fitting technology, specifically to a press-fitting mechanism. Background Technology

[0002] The existing pressing mechanism uses a method of periodically adjusting the position of the upper pressing head, and after pressing, operators check the inner wall of the pressing hole for damage in real time, and report any abnormalities promptly. However, this adjustment method is relatively slow and is affected by installation errors, so the actual installation position of the product inevitably deviates. Even if the position of the upper pressing head is adjusted, the upper pressing head may still scratch the inner wall of the pressing hole during the pressing process, reducing the product yield. Utility Model Content

[0003] The purpose of this application is to provide a pressing mechanism that solves the problem of scratching the inner wall of the pressing hole during the pressing process of the pressing head, thereby improving the product yield.

[0004] To address the aforementioned technical problems, this application provides a pressing mechanism for pressing a component to be pressed onto a product, wherein the product has a pressing hole, and the pressing mechanism includes:

[0005] Drive mechanism;

[0006] An image acquisition mechanism is provided, which is drivenly connected to the driving mechanism. The image acquisition mechanism has a working position in which it can acquire image information of the actual installation position of the product.

[0007] The upper pressure head is drivenly connected to the drive mechanism.

[0008] The controller is electrically connected to the image acquisition mechanism and the drive mechanism. The controller can obtain the installation position deviation of the product based on the actual installation position and the theoretical installation position of the product, and control the drive mechanism based on the installation position deviation to make the upper pressure head and the pressure hole coaxial.

[0009] To address the issue of the upper pressure head potentially scratching the inner wall of the pressure hole during the pressing process, this application's pressing mechanism includes a drive mechanism, an image acquisition mechanism, and a controller. The image acquisition mechanism acquires image information of the actual installation position of the product and transmits the image acquisition results to the controller. The controller has pre-stored image information of the theoretical installation position of the product. The controller compares the actual installation position with the theoretical installation position to determine the installation position deviation. Based on this deviation, the drive mechanism is controlled to adjust the position of the upper pressure head, ensuring that the upper pressure head and the pressure hole are coaxial. This compensates for the installation position deviation and minimizes the risk of the upper pressure head scratching the inner wall of the pressure hole during the pressing process. This reduces product damage and significantly improves product yield. The pressing mechanism of this application uses an automated adjustment method to replace traditional manual experience operation, reducing the need for manual intervention, avoiding human judgment errors, ensuring stable pressing quality of different batches of products, and improving production efficiency. At the same time, the image acquisition mechanism and the drive mechanism are connected, and the image acquisition mechanism can have different working positions. In other words, the drive mechanism can move the image acquisition mechanism to the optimal observation position, ensuring that the acquired image information can cover the key areas of the product, improving detection accuracy, reducing the risk of misjudgment due to limited or offset field of view, and meeting the detection needs of different types of products, making the pressing mechanism of this application more compatible.

[0061] Please refer to Figures 1-4 , Figure 1 This is a schematic diagram of a specific embodiment of the pressing mechanism provided in this application; Figure 2 for Figure 1 A schematic diagram of the press-fitting mechanism after the product is installed; Figure 3 for Figure 2 A structural diagram of the second angle; Figure 4 for Figure 1 A magnified view of a portion of area A in the pressing mechanism.

[0062] This embodiment provides a pressing mechanism for pressing a component to be pressed onto product 01. Product 01 has a pressing hole. The pressing mechanism includes:

[0063] Drive mechanism 1;

[0064] Image acquisition mechanism 9 is connected to drive mechanism 1. Image acquisition mechanism 9 has a working position. In the working position, image acquisition mechanism 9 can acquire image information of the actual installation position of product 01.

[0065] Upper pressure head 2 is connected to drive mechanism 1.

[0066] The controller is electrically connected to the image acquisition mechanism 9 and the drive mechanism 1. The controller can obtain the installation position deviation of the product 01 based on the actual installation position and the theoretical installation position of the product 01, and control the drive mechanism 1 according to the installation position deviation to make the upper pressure head 2 and the pressure hole coaxial.

[0067] To address the potential for the upper pressure head 2 to scratch the inner wall of the pressure hole during the pressing process, this embodiment of the pressing mechanism includes a drive mechanism 1, an image acquisition mechanism 9, and a controller. The image acquisition mechanism 9 acquires image information of the actual installation position of product 01 and transmits the image acquisition results to the controller. The controller has pre-stored image information of the theoretical installation position of product 01. The controller compares the actual installation position of product 01 with the theoretical installation position to obtain the installation position deviation of product 01. Based on this installation position deviation, the controller controls the drive mechanism 1 to adjust the position of the upper pressure head 2, ensuring that the upper pressure head 2 and the pressure hole are coaxial. This compensates for the installation position deviation of product 01 and minimizes the risk of the upper pressure head 2 scratching the pressure hole during the pressing process. The inner wall reduces product damage and significantly improves product yield. In this embodiment, the pressing mechanism uses an automated adjustment method to replace traditional manual experience operation, reducing the need for manual intervention, avoiding human judgment errors, ensuring stable pressing quality of different batches of product 01, and improving production efficiency. At the same time, the image acquisition mechanism 9 and the drive mechanism 1 are connected, and the image acquisition mechanism 9 can have different working positions. In other words, the drive mechanism 1 can drive the image acquisition mechanism 9 to move to the optimal observation position, ensuring that the obtained image information can cover the key areas of product 01, improving detection accuracy, reducing the risk of misjudgment due to limited or offset field of view, and meeting the detection needs of different types of product 01, making the pressing mechanism of this embodiment more compatible.

[0068] It is understandable that when obtaining the theoretical and actual installation positions of the same product 01, the image acquisition mechanism 9 is located in the same working position. That is, both the theoretical and actual installation positions of product 01 are acquired based on the same observation benchmark (fixed viewing angle, fixed focal length), ensuring that the image coordinate system is completely consistent, eliminating calculation errors caused by viewing angle switching, and reducing calculation complexity. For example, when the image acquisition mechanism 9 is in the working position, it can be located directly above the pressure hole.

[0069] It should be noted that this application does not limit the specific structure of the image acquisition mechanism 9, as long as it can obtain image information of product 01. As a preferred embodiment, the image acquisition mechanism 9 includes a camera.

[0070] Furthermore, the specific structure and control principle of the controller are existing technologies well known to those skilled in the art, and will not be described in detail here.

[0071] In some embodiments of this application, the image acquisition mechanism 9 and the upper pressure head 2 are relatively fixed, and the driving mechanism 1 can drive the image acquisition mechanism 9 and the upper pressure head 2 to move synchronously.

[0072] As set up above, the spatial relationship between the image acquisition mechanism 9 and the upper pressure head 2 remains constant. During the pressing process of the upper pressure head 2, the image acquisition mechanism 9 can continuously acquire image information of the product 01. The controller can correct the trajectory of the upper pressure head 2 in real time based on the synchronously acquired image information, further improving the positional accuracy of the upper pressure head 2. At the same time, the constant spatial relationship between the image acquisition mechanism 9 and the upper pressure head 2 eliminates the need for complex coordinate transformation calculations, which helps to reduce computational complexity. The image acquisition mechanism 9 and the upper pressure head 2 are synchronously driven by the same motion unit. Compared with the image acquisition mechanism 9 and the upper pressure head 2 being driven by different motion units, this can also reduce the number of motion units, simplify the structure of the pressing mechanism, and reduce the cost of the pressing mechanism.

[0073] The relative positions of the image acquisition mechanism 9 and the upper pressure head 2 are not restricted; for example, the image acquisition mechanism 9 can be located on one side of the upper pressure head 2.

[0074] In some embodiments, such as Figure 4 As shown, the upper pressure head 2 has a mounting groove 2a with an opening at the lower end. The axis of the mounting groove 2a coincides with the axis of the upper pressure head 2. The image acquisition mechanism 9 is disposed inside the mounting groove 2a and is coaxially arranged with the upper pressure head 2.

[0075] As described above, the image acquisition mechanism 9 is located inside the mounting slot 2a of the upper pressure head 2. The image acquisition mechanism 9 and the upper pressure head 2 are coaxially arranged. First, this improves the integration of the image acquisition mechanism 9 and the upper pressure head 2, making the pressing mechanism more compact and reducing its size. Second, the upper pressure head 2 also protects the image acquisition mechanism 9, reducing interference and damage from the external environment and improving its durability. Third, the coaxial arrangement of the image acquisition mechanism 9 and the upper pressure head 2 ensures that the acquired image information and the axis of the pressing action are consistent, which helps to more accurately control the pressing position of the upper pressure head 2 and reduce deviations. Finally, the absolute coordinates of the image acquisition mechanism 9 and the upper pressure head 2 are aligned, eliminating the need for complex coordinate transformation calculations and reducing computational complexity.

[0076] In some other embodiments of this application, the driving mechanism 1 includes a first driving part and a second driving part, the first driving part being driven connected to the image acquisition mechanism 9, and the second driving part being driven connected to the upper pressure head 2.

[0077] As set up above, the first drive unit is connected to the image acquisition mechanism 9, and the second drive unit is connected to the upper pressure head 2. The image acquisition mechanism 9 and the upper pressure head 2 are controlled independently. Through the precise control of the image acquisition mechanism 9 by the first drive unit, the actual installation position of the product 01 can be obtained more accurately, providing precise positioning information for the second drive unit to drive the upper pressure head 2. The image acquisition mechanism 9 and the upper pressure head 2 move independently, and their movements can be adjusted according to actual needs, improving the flexibility and accuracy of operation.

[0078] The connection method between the first drive unit and the image acquisition mechanism 9 is not limited. For example, threaded connectors can be used to fix the first drive unit and the image acquisition mechanism 9.

[0079] Specifically, the first drive unit can be a robotic arm, and the image acquisition mechanism 9 is connected to the end of the robotic arm. The robotic arm can precisely control the motion trajectory of the image acquisition mechanism 9, thereby improving the motion accuracy of the image acquisition mechanism 9.

[0080] Furthermore, the image acquisition mechanism 9 also has a retrieval position, in which the image acquisition mechanism 9 is away from the product 01.

[0081] As set up above, after completing image acquisition, the image acquisition mechanism 9 can be moved to the recycling position to move away from the product 01, thereby freeing up space for the pressing operation of the upper pressure head 2, thus not interfering with the pressing process, improving the safety of the equipment, and also preventing damage to the image acquisition mechanism 9 caused by the pressing operation of the upper pressure head 2, thus improving the durability of the image acquisition mechanism 9.

[0082] In embodiments where the image acquisition mechanism 9 and the upper pressure head 2 are relatively fixed, the drive mechanism 1 only includes a second drive unit, such as... Figure 3 As shown, the second drive unit specifically includes:

[0083] The first servo mechanism 11 has an output shaft that extends along a first direction.

[0084] The second servo mechanism 12 is connected to the output shaft of the first servo mechanism 11. The output shaft of the second servo mechanism 12 extends along the second direction and is driven to connect with the upper pressure head 2.

[0085] The first direction, the second direction, and the height direction are perpendicular to each other.

[0086] As configured above, the output shaft of the first servo mechanism 11 extends along the first direction, and the output shaft of the first servo mechanism 11 is connected to the second servo mechanism 12. That is, the extension and retraction of the output shaft of the first servo mechanism 11 can drive the second servo mechanism 12 to move along the first direction. The output shaft of the second servo mechanism 12 extends along the second direction, and the output shaft of the second servo mechanism 12 is driven to connect with the upper pressure head 2. That is, the extension and retraction of the output shaft of the second servo mechanism 12 can drive the upper pressure head 2 to move along the second direction. The first direction, the second direction, and the height direction are perpendicular to each other. Through the combination of the two servo mechanisms, the upper pressure head 2 can be precisely adjusted in the horizontal direction to ensure the precise alignment of the upper pressure head 2 during the pressing process. At the same time, servo mechanisms usually have high control accuracy. Using a servo mechanism as a power unit can improve the control accuracy of the upper pressure head 2.

[0087] The first servo mechanism 11 and the second servo mechanism 12 include servo motors. Servo motors are existing technologies well known to those skilled in the art and will not be described in detail here.

[0088] The pressing mechanism includes a fixed base and a first adapter. The main body of the first servo mechanism 11 is fixed to the fixed base. The specific fixing method is not limited, such as fixing by threaded connectors, welding, or snap-fit. The first adapter is connected to the output shaft of the first servo mechanism 11 and is movably supported by the fixed base. The first adapter can fix the main body of the second servo mechanism 12. To improve the positional accuracy of the first adapter, a guide mechanism can be set between the first adapter and the fixed base. The guide mechanism includes a sliding guide rail and a slider. The guide rail is fixed to the fixed base, and the slider is fixed to the first adapter. The fixing method of the first adapter and the main body of the second servo mechanism 12 is not limited, such as fixing by threaded connectors, welding, or snap-fit.

[0089] In some embodiments, product 01 has at least two pressure holes, and a first direction or a second direction is the extension direction of the line connecting two of the pressure holes.

[0090] In other words, when the first servo mechanism 11 or the second servo mechanism 12 is in a fixed state, the output shaft of the first servo mechanism 11 extends along the extension direction of the line connecting the two pressing holes, or the output shaft of the second servo mechanism 12 extends along the extension direction of the line connecting the two pressing holes. With this configuration, when the upper pressing head 2 needs to move from one pressing hole to another, only the first servo mechanism 11 or the second servo mechanism 12 needs to be controlled individually. This minimizes unnecessary mechanical movement and adjustment time, simplifies the control strategy, and improves production efficiency and control accuracy of the upper pressing head 2.

[0091] Furthermore, in some embodiments of this application, the pressing mechanism further includes:

[0092] Two displacement sensors are provided. One displacement sensor is linked to the output shaft of the first servo mechanism 11 to detect the displacement of the output shaft of the first servo mechanism 11. The other displacement sensor is linked to the output shaft of the second servo mechanism 12 to detect the displacement of the output shaft of the second servo mechanism 12. The displacement sensors are electrically connected to the controller.

[0093] As set up above, the two displacement sensors can provide real-time feedback on the displacement of the output shaft of the first servo mechanism 11 and the displacement of the output shaft of the second servo mechanism 12, helping the controller to adjust the movement of the two servo mechanisms in a timely manner, avoiding deviations as much as possible, ensuring that the movement of the output shaft of the first servo mechanism 11 in the first direction is precise and controllable, and ensuring that the movement of the output shaft of the second servo mechanism 12 in the second direction is precise and controllable, thereby achieving precise control of the upper pressure head 2.

[0094] A displacement sensor is a device that converts mechanical displacement into an electrical signal. The specific form of the displacement sensor is not limited; for example, it can be a laser displacement sensor, a magnetoelectric displacement sensor, etc. In some embodiments of this application, the displacement sensor includes a grating ruler, which includes a grating ruler body and a grating ruler reading head slidably mounted on the grating ruler body. The grating ruler body is connected to a first servo mechanism 11 or a second servo mechanism 12, and the grating ruler reading head can move synchronously with the output shaft of the first servo mechanism 11 or the output shaft of the second servo mechanism 12.

[0095] As configured above, the grating ruler body has precisely engraved grating lines. When the output shaft of the first servo mechanism 11 or the output shaft of the second servo mechanism 12 moves, the grating ruler reading head can move along the grating ruler body and read the grating lines. By calculating the changes in the grating lines, the displacement of the output shaft of the first servo mechanism 11 or the second servo mechanism 12 can be accurately measured. Using the grating ruler as a displacement sensor can significantly improve the motion accuracy of the first servo mechanism 11 or the second servo mechanism 12, achieving precise control of the upper pressure head 2.

[0096] Please continue to refer to this. Figures 1-5 , Figure 5 for Figure 1 A partial enlarged view of the pressing table in the pressing mechanism.

[0097] In some embodiments of this application, the pressing mechanism further includes:

[0098] The pressing table 3 includes a positioning part 31 for positioning and installing product 01;

[0099] Column 4 is connected to the output shaft of the second servo mechanism 12;

[0100] The bracket 5 is slidably installed on the column 4 along the height direction. The bracket 5 includes an upper horizontal part 51 located above the pressing table 3 and a lower horizontal part 52 located below the pressing table 3. The bracket 5 also includes a vertical part 53 extending along the height direction. The upper horizontal part 51 is connected to the upper end of the vertical part 53, and the lower horizontal part 52 is connected to the lower end of the vertical part 53.

[0101] The first lifting mechanism 6 is installed on the column 4. The output shaft of the first lifting mechanism 6 extends along the height direction and is connected to the bracket 5.

[0102] The second lifting mechanism 7 is installed on the upper horizontal part 51. The output shaft of the second lifting mechanism 7 extends along the height direction and is connected to the upper pressure head 2. The driving force of the second lifting mechanism 7 is greater than the driving force of the first lifting mechanism 6.

[0103] The pressing head 8 is slidably disposed along the height direction and is located above the lower horizontal part 52. The top of the pressing head 8 has a mounting part 8A for mounting the part to be pressed. The pressing head 8 can abut against the lower horizontal part 52 and move upward under the thrust of the lower horizontal part 52 to press the part to be pressed onto the product 01. The pressing head 8 can also return to the initial position after the thrust of the lower horizontal part 52 is removed.

[0104] When the upper pressure head 2 and the pressure hole have been adjusted to be in a coaxial state, the pressing process of the pressing mechanism in this embodiment is as follows:

[0105] The output shaft of the second lifting mechanism 7 extends under the action of driving force and drives the upper pressure head 2 to move downward. The upper pressure head 2 enters the pressure hole of product 01 and abuts against the pressure hole step on the inner wall of the pressure hole.

[0106] The second lifting mechanism 7 continues to apply driving force. Since the upper pressure head 2 and the pressure hole step on the inner wall of the pressure hole abut against each other, the output shaft of the second lifting mechanism 7 cannot continue to move downward. The driving force of the second lifting mechanism 7 is greater than the driving force of the first lifting mechanism 6. Under the action of the driving force of the second lifting mechanism 7, the main body of the second lifting mechanism 7 can overcome the driving force of the first lifting mechanism 6 and move in the opposite direction, and drive the bracket 5 to move upward, so that the output shaft of the first lifting mechanism 6 retracts. When the lower horizontal part 52 and the lower pressure head 8 abut against each other, under the pushing action of the lower horizontal part 52, the lower pressure head 8 and the bracket 5 move upward synchronously and press the part to be pressed onto the product 01.

[0107] After the pressing is completed, the output shaft of the second lifting mechanism 7 retracts and drives the upper pressing head 2 to move upward; the output shaft of the first lifting mechanism 6 extends and pushes the bracket 5 downward, and the lower pressing head 8 returns to its initial position after the thrust of the lower horizontal part 52 is removed.

[0108] As can be seen from the above description, in this embodiment, the bracket 5 forms a C-shaped reaction device. During the entire pressing process, by controlling the thrust of the output shaft of the second lifting mechanism 7, the pressure information during the pressing process can be monitored and fed back in real time. This allows for accurate control of the pressure of the upper pressure head 2 and the lower pressure head 8 on the product 01, improving the accuracy and reliability of pressure control, enhancing the pressing quality and stability, and avoiding problems such as product deformation or incomplete pressing caused by uneven pressure.

[0109] The first lifting mechanism 6 and the second lifting mechanism 7 can be power mechanisms capable of generating linear displacement, such as lifting cylinders, hydraulic cylinders, and electric cylinders.

[0110] The pressing mechanism also includes a second adapter seat, which is movably supported by the first adapter seat. The second adapter seat can fix the column 4. In order to improve the positional accuracy of the second adapter seat, a guide mechanism can be set between the second adapter seat and the first adapter seat. The guide mechanism includes a sliding guide rail and a slider. The guide rail is fixed to the first adapter seat and the slider is fixed to the second adapter seat. The fixing method between the second adapter seat and the column 4 is not limited. For example, it can be fixed by threaded connectors, welding, or snap-fit.

[0111] Please continue to refer to this. Figure 1In some embodiments of this application, a guide rail is connected to one of the opposite sidewalls of the column 4 and the bracket 5, extending along the height direction, and a slider is connected to the other sidewall, with the slider slidably mounted on the guide rail. Thus, the sliding cooperation of the guide rail and the slider guides the bracket 5, ensuring that the bracket 5 can only slide along the extension direction of the guide rail, improving the movement accuracy of the bracket 5 and further improving the movement accuracy of the upper pressure head 2.

[0112] In other embodiments of this application, one of the opposing sidewalls of the column 4 and the bracket 5 is provided with a guide groove extending along the height direction, and the other is connected with a guide block, which is slidably inserted into the inside of the guide groove. In this way, the sliding cooperation between the guide groove and the guide block can also guide the bracket 5, further improving the movement accuracy of the upper pressure head 2.

[0113] Please continue to refer to this. Figure 1 In some embodiments of this application, the support 5 is provided with a guide rail on the side wall of the upper pressure head 2, the guide rail extending along the height direction, and a slider is connected to the connection between the output shaft of the second lifting mechanism 7 and the upper pressure head 2, the slider being slidably mounted on the guide rail. Thus, the sliding cooperation between the guide rail and the slider further guides the upper pressure head 2, ensuring that the upper pressure head 2 can only slide along the extension direction of the guide rail, further improving the movement accuracy of the upper pressure head 2.

[0114] In other embodiments of this application, the support 5 has a guide groove on the side wall of the upper pressure head 2, which extends along the height direction. A slider is connected to the connection between the output shaft of the second lifting mechanism 7 and the upper pressure head 2, and the slider is slidably inserted into the inside of the guide groove. In this way, the sliding cooperation between the guide groove and the guide block can also guide the upper pressure head 2, further improving the movement accuracy of the upper pressure head 2.

[0115] Please refer to Figures 6-8 , Figure 6 for Figure 1 A partial structural diagram of the lower pressure head in the pressing mechanism; Figure 7 for Figure 6 A structural diagram of the second angle; Figure 8 for Figure 1 Another partial structural diagram of the lower pressure head in the pressing mechanism.

[0116] In some embodiments of this application, the pressure head 8 includes:

[0117] An external pressure head 81 is slidably disposed along the height direction. The external pressure head 81 is a hollow structure with an opening at the top. The side wall of the external pressure head 81 has a groove 81a extending along the height direction, and the groove 81a penetrates the open end wall of the external pressure head 81.

[0118] An inner pressure head 82 is installed inside an outer pressure head 81. A mounting portion 8A is formed in a portion of the outer pressure head 81 above the inner pressure head 82. The peripheral wall of the inner pressure head 82 has a protrusion 821. The protrusion 821 is slidably installed inside a groove 81a. When the lower pressure head 8 is in the initial position, the lower side wall of the protrusion 821 abuts against the closed end wall of the groove 81a. There is a gap L between the upper side wall of the protrusion 821 and the open end wall of the outer pressure head 81.

[0119] Push rod 83 extends along the height direction. The upper end of push rod 83 is connected to the internal pressure head 82, and the lower end of push rod 83 can abut against the lower horizontal part 52.

[0120] When the push rod 83 moves upward, the first elastic element 84 gradually stores energy, and when the inner pressure head 82 moves upward relative to the outer pressure head 81, the second elastic element 85 gradually stores energy.

[0121] As set up above, during the pressing process of the pressing mechanism, when the lower end of the push rod 83 abuts against the lower horizontal part 52, the push rod 83 will move upward under the pushing force of the lower horizontal part 52, and push the outer pressing head 81 and the inner pressing head 82 to move upward synchronously. At this time, the first elastic element 84 gradually stores energy. When the outer pressing head 81 moves to abut against the lower surface of the product 01, the outer pressing head 81 can no longer move upward. The inner pressing head 82 will move upward relative to the outer pressing head 81 under the pushing force. At this time, the second elastic element 85 gradually stores energy. When the upper side wall of the protrusion 821 is flush with the opening end wall of the outer pressing head 81, the upper side wall of the protrusion 821 also abuts against the lower surface of the product 01. The inner pressing head 82 can no longer move upward. At this time, the pressing part is pressed into place. When the thrust of the horizontal part 52 on the push rod 83 is removed, under the restoring force of the first elastic element 84 and the second elastic element 85, both the external pressure head 81 and the internal pressure head 82 return to their initial positions.

[0122] Therefore, in this embodiment, the pressing head 8, through the cooperation of the external pressing head 81 and the internal pressing head 82, can more precisely control the pressing depth and pressing force of the part to be pressed, ensuring that the part to be pressed can be accurately pressed into the pressing hole of the product 01; the distance L between the protrusion 821 and the opening end wall of the external pressing head 81 can adjust the rising stroke of the internal pressing head 82, thereby controlling the pressing depth of the part to be pressed and improving the consistency of pressing; the setting of the first elastic element 84 and the second elastic element 85 can realize the control of the pressing force during the pressing process, making the pressing force more uniform and controllable, avoiding damage to the product 01; after the pressing is completed, the first elastic element 84 and the second elastic element 85 can also realize the automatic reset of the external pressing head 81 and the internal pressing head 82, improving the degree of automation.

[0123] Depend on Figure 7 and Figure 8 It can be seen that the downward pressure head 8 also includes:

[0124] Workbench 86, fixed setting;

[0125] The sliding part 87 is slidably disposed on the worktable 86 along the height direction;

[0126] The push rod 83 passes through the worktable 86, the sliding part 87, and the external pressure head 81. The push rod 83 has a first step and a second step. The first step can abut against the lower side wall of the sliding part 87 to push the sliding part 87 to move upward synchronously. The first elastic member 84 is fitted onto the push rod 83 and is axially limited between the lower side wall of the worktable 86 and the second step. The second elastic member 85 is fitted onto the push rod 83 and is axially limited between the sliding part 87 and the external pressure head 81.

[0127] As set up above, during the pressing process of the pressing mechanism, when the lower end of the push rod 83 abuts against the lower horizontal part 52, the push rod 83 will move upward under the pushing force of the lower horizontal part 52, and push the sliding part 87, the external pressing head 81 and the internal pressing head 82 to move upward synchronously. At this time, the first elastic element 84 gradually stores energy. When the external pressing head 81 moves to abut against the lower surface of the product 01, the external pressing head 81 can no longer move upward. The sliding part 87 and the internal pressing head 82 will move upward relative to the external pressing head 81 under the pushing force. At this time, the second elastic element 85 gradually stores energy. When the upper side wall of the protrusion 821 is flush with the opening end wall of the external pressing head 81, the upper side wall of the protrusion 821 also abuts against the lower surface of the product 01. The internal pressing head 82 can no longer move upward. At this time, the pressing part is pressed into place. When the thrust of the horizontal part 52 on the push rod 83 is removed, under the restoring force of the first elastic element 84 and the second elastic element 85, the sliding part 87, the outer pressure head 81 and the inner pressure head 82 all return to their initial positions.

[0128] In some embodiments of this application, the worktable 86 is fixedly disposed on the pressing table 3. A guide rail is connected to one of the opposing side walls of the worktable 86 and the sliding part 87, extending along the height direction. A slider is connected to the other side wall, and the slider is slidably mounted on the guide rail, thus achieving a sliding connection between the worktable 86 and the sliding part 87. Simultaneously, the sliding cooperation between the guide rail and the slider also guides the sliding part 87, improving its movement accuracy.

[0129] Please continue to refer to this. Figure 4In this embodiment, the pressing table 3 includes a pressing table body 32, and a positioning part 31 is disposed on the upper side wall of the pressing table body 32. The positioning part 31 includes a positioning pin (not shown in the figure), a support column 311, and a pressing part 312. The positioning pin can be inserted into the positioning hole of the product 01 to position the product 01. The support column 311 supports the product 01. The pressing part 312 includes a horizontally extending pressing rod. The pressing rod can rotate and switch between a pressing position and a release position. When the pressing rod is in the pressing position, the pressing rod abuts against the upper surface of the product 01, thereby pressing the product 01 onto the upper side wall of the pressing table body 32, thereby limiting the product 01 in the height direction and improving the installation stability of the product 01. When the pressing rod is in the release position, the pressing rod disengages from the upper surface of the product 01, releasing the limitation on the product 01 in the height direction, making it easy to remove the pressed product 01.

[0130] The pressing part 312 can be a rotary pressing cylinder, which can apply downward pressure while the pressing rod is rotating, ensuring reliable pressing of product 01.

[0131] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
