Description

Technical Field

[0001] This application relates to the field of press-fitting equipment technology, and more specifically, to a pre-pressing structure and press-fitting equipment. Background Technology

[0002] In the assembly process of components such as mobile phone screens and cover plates, press-fitting equipment is required. This equipment applies pressure to these components to complete their assembly. To improve assembly efficiency, pre-pressing is typically performed on the assembly structure, applying a certain pre-pressure to the workpiece. This pre-pressure reduces the force required during subsequent processing, meaning the press-fitting equipment needs to move less, thus effectively improving assembly efficiency.

[0003] Existing preloading structures typically require complete disassembly to adjust the preload by modifying internal adjustment components; alternatively, complex procedures are needed to adjust the preload applied to the workpiece. Therefore, existing preloading structures are inefficient. Utility Model Content

[0037] Various embodiments of this application may exist in the form of a range; it should be understood that the description in the form of a range is merely for convenience and brevity and should not be construed as a hard limitation on the scope of this application; therefore, it should be considered that the range description has specifically disclosed all possible sub-ranges and single numerical values ​​within that range. For example, it should be considered that the range description from 1 to 6 has specifically disclosed sub-ranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6, etc., and single numbers within the range, such as 1, 2, 3, 4, 5, and 6, regardless of the range. Furthermore, whenever a numerical range is referred to herein, it means including any referenced number (fraction or integer) within the referred range.

[0038] refer to Figures 1-3 This application provides a pre-compression structure 10, which includes:

[0039] The main body is equipped with an adjustment section 131;

[0040] Detection component 300 is installed inside the main body;

[0041] The pressure application component has a groove 203 on the side away from the detection element 300. The adjustment part 131 passes through the pressure application component and is located in the groove 203. The pressure application component is slidably connected to the main body and is used to reciprocate in the direction toward the detection element 300.

[0042] The elastic element 600 has one end abutting against the pressure application component and the other end abutting against the detection element 300;

[0043] An adjusting member 400 is disposed in the groove 203 and connected to the adjusting part 131, and is used to reciprocate along the direction from the pressure applying component to the detection component 300 to limit the distance between the pressure applying component and the detection component 300.

[0044] In this embodiment, the usage process of the pre-pressure structure 10 is as follows: First, the workpiece is placed on the processing table. Second, the pressure-applying component of the pre-pressure structure 10 is moved toward the workpiece from the side away from the detection element 300, and the pre-pressure structure 10 moves toward the workpiece. Then, as the pressure-applying structure contacts the workpiece, the workpiece is subjected to pre-pressure, and the elastic element 600 will also continuously deform and shrink. The detection element 300 will obtain the current pressure applied to the workpiece through the elastic element 600, and the workpiece will be subjected to a gradually increasing force.

[0045] If, after the pressure is detected by the detection element 300, it is found that the pre-pressure set by the pre-pressure structure 10 is too small, causing the pre-pressure structure 10 to need to move a long distance toward the workpiece, the pre-pressure structure 10 can be lifted away from the workpiece first, and then the adjustment element 400 can be driven to move toward the detection element 300. In turn, the adjustment element 400 drives the pressure application component to move toward the detection element 300, while compressing the elastic element 600. This allows the detection element 300 to detect a large pre-pressure before contacting the workpiece, and also ensures that the pressure on the workpiece is large enough at the moment it is squeezed by the pre-pressure structure 10 (the elastic element 600 has a tendency to produce elastic deformation).

[0046] Therefore, the pre-pressure structure 10 of this application can change the current pre-pressure by moving the adjusting member 400 to drive the elastic member 600 of the pressure application component to deform. Simultaneously, because the groove 203 is located on the side away from the detection member 300 during pressure application, and the adjusting member 400 is located within the groove 203, the pressure application component will not damage the adjusting member 400 during operation. Furthermore, the user can directly control the adjusting member 400 by inserting a tool or hand into the groove 203. Therefore, the pre-pressure adjustment of the pre-pressure structure 10 is convenient and quick. In summary, the pre-pressure structure 10 of this application has high efficiency in both use and pre-pressure adjustment.

[0047] It should be understood that the pressure application component can be... Figure 1The device consists of a suction cup mounting plate 202, a pad 201, a slider connecting plate 220, and a slider 230. A suction cup can also be installed on the side of the pad 201 away from the detection element 300. The detection element can be a pressure sensor.

[0048] In one embodiment, please refer to Figures 1-3 In the figure, the Z-axis points upwards. The main body includes a shell and a connecting rod 130. The shell is provided with a receiving cavity 101 and a connecting channel (not marked in the figure). The connecting channel connects the receiving cavity 101 and the external environment. The detection element 300 is disposed in the receiving cavity 101.

[0049] At least a portion of the connecting rod 130 is located within the connecting channel, with one end of the connecting rod 130 connected to the inner wall of the receiving cavity 101 away from the pressure application component, and the other end provided with an adjustment part 131.

[0050] In this embodiment, the receiving cavity 101 can effectively accommodate the detection element 300, and the connecting channel can limit the movement of the connecting rod 130. When one end of the connecting rod 130 is connected to the inner wall of the receiving cavity 101 away from the pressure application component, the pressure application component can be "suspended" by the connecting rod 130, that is, the adjusting element 400 prevents the pressure application component from sliding down from the connecting rod 130.

[0051] In one embodiment, please refer to Figures 1-3 The outer casing is provided with a mounting assembly 110 and a guide rail 120, and the receiving cavity 101 is disposed within the mounting assembly 110;

[0052] The pre-compression structure 10 also includes a baffle 700, which is disposed at one end of the mounting assembly 110 near the pressure application assembly. The guide rail 120 is connected to the outer wall of the mounting assembly 110 and abuts against the baffle 700. The pressure application assembly is slidably connected to the guide rail 120.

[0053] In this embodiment, the guide rail 120 can guide and restrict the reciprocating movement of the pressure application component. Since the baffle 700 is disposed at the end of the mounting component 110 near the pressure application component, the guide rail 120 can be abutted by the baffle 700 in the vertical direction to prevent it from sliding off during installation and use, thereby improving the assembly efficiency of the pre-compression structure 10 and also improving the service life of the pre-compression structure 10.

[0054] It should be understood that the installation component 110 may include Figure 1 The guide rail mounting base 111, the connecting flange 112, and the mounting plate 113.

[0055] In one embodiment, please refer to Figures 1-3The pressure application assembly includes a pressure plate, a slider 230 and a slider connecting plate 220. The slider connecting plate 220 is connected to the pressure plate, and the slider 230 is connected to the guide rail 120 and the slider connecting plate 220 for reciprocating movement along the guide rail 120.

[0056] The baffle 700 also abuts against the slider 230 to restrict the slider 230 from moving away from the receiving cavity 101.

[0057] In this embodiment, when the slider 230 reciprocates on the guide rail 120, the baffle 700 can limit its range of movement to prevent the pressure application component from slipping during use, thereby improving the service life of the pre-pressure structure 10.

[0058] In one embodiment, please refer to Figures 1-3 The main body includes a mounting plate 113, a connecting flange 112, a guide rail mounting seat 111, and a connecting rod 130. The mounting plate 113 is located at the end of the connecting flange 112 away from the pressure application component, so as to define a receiving cavity 101 together with the connecting flange 112. The detection element 300 is located in the receiving cavity 101. The mounting plate 113 is used to connect with external devices.

[0059] One end of the connecting rod 130 is fixedly connected to the mounting plate 113, and the other end is provided with an adjustment part 131.

[0060] In this embodiment, the connecting flange 112 can be detachably connected to the receiving cavity 101. In this case, if the detection component 300 needs to be replaced, the receiving cavity 101 can be quickly opened by removing the mounting plate 113. The mounting plate 113 can be connected to external structures such as robotic arms, thereby facilitating the movement and rotation of the pre-pressurization structure 10 during processing. Because the connecting rod 130 is connected to the mounting plate 113, when disassembling the pressure application component and the connecting flange 112, the connecting rod 130 can be prevented from falling off directly along with the two, thus avoiding damage from impact with the external environment.

[0061] In one embodiment, please refer to Figures 1-3 The detection element 300 is fixedly connected to the inner wall of the receiving cavity 101, and the connecting rod 130 passes through the detection element 300.

[0062] In this embodiment, because the detection element 300 is fixedly connected to the inner wall of the receiving cavity 101, damage to the detection element 300 due to shaking within the receiving cavity 101 can be effectively prevented. Simultaneously, the design of the connecting rod 130 passing through the detection element 300 allows the connecting rod 130 to guide the detection element 300 during installation of the pre-compression structure 10, thus enabling the detection element 300 to be quickly installed on the mounting plate 113. When the connecting rod 130 and the detection element 300 are connected, they also interlock, preventing the entire assembly from detaching even if the connection between either fails.

[0063] In one embodiment, please refer to Figures 1-3 The adjusting element 400 is a nut, and the adjusting part 131 is provided with threads. The nut is sleeved on the adjusting part 131 and connected to the threads.

[0064] In this embodiment, when the adjusting member 400 is a nut, the user can rotate the nut so that the nut moves quickly along the thread toward or away from the detection member 300, thereby changing the distance between the pressure application component and the detection member 300 and thus adjusting the magnitude of the pre-pressure.

[0065] In one embodiment, please refer to Figures 1-3 A sleeve 500 is also provided between the elastic element 600 and the pressure application component. The sleeve 500 is sleeved on the adjustment part 131 and is located between the elastic element 600 and the pressure application component.

[0066] In this embodiment, the sleeve 500 can first play a certain sealing role to prevent external moisture and particulate matter from entering the receiving cavity 101 and affecting the detection element 300; at the same time, the sleeve 500 can also serve as a bridge connecting the elastic element 600 and the pressure application component, reducing the length of the elastic element 600 (vertical direction), thereby preventing the elastic element 600 from being too long and causing a decrease in the deformation recovery rate.

[0067] In one embodiment, please refer to Figures 1-3 The outer wall of the main body is provided with scales, which are arranged sequentially along the moving direction of the pressure component. When the pressure component moves back and forth, it will also cover or expose the scales.

[0068] In this embodiment, since the scale is arranged sequentially along the moving direction (Z-axis direction) of the pressure component, after the pressure component is pressed onto the workpiece surface, as the pressure component moves toward the detection element 300, the scale will gradually be blocked by the pressure component. At this time, the junction of the pressure component and the scale can clearly indicate the pressure value that the detection element 300 should currently have, thereby allowing the user to quickly judge the current pre-pressure magnitude.

[0069] It should be understood that when the detection component 300 is a pressure sensor, if the pressure sensor is not powered on before assembling the pre-pressure structure, the current pre-pressure value can still be confirmed by observing the scale.

[0070] Accordingly, this application also provides a pressing device, which includes the pre-compression structure 10 of any of the above embodiments.

[0071] In this embodiment, the pressing equipment includes the pre-compression structure 10 of any of the above embodiments. Therefore, it can change the current pre-compression pressure by moving the adjusting member 400 to drive the pressure application component to deform the elastic member 600. At the same time, since the groove 203 is located on the side away from the detection member 300 and the adjusting member 400 is located in the groove 203, the pressure application component will not damage the adjusting member 400 when it is working. Moreover, the user can directly control the adjusting member 400 by inserting an instrument or hand into the groove 203. Therefore, the pre-compression adjustment of the pressing equipment is convenient and quick.
