Description

Technical Field

[0001] This application relates to the field of neutralization cup assembly equipment technology, and in particular to an assembly fixture for a neutralization cup. Background Technology

[0002] Neutralization cups, a common laboratory instrument, are widely used in chemical analysis, materials testing, and other fields. Their structure typically includes a basket, a lid, and a body. The basket is mounted on the lid and used in conjunction with the body to neutralize samples. With increasing demands for experimental precision, the assembly process of neutralization cups has become increasingly important, especially the connection between the lid and the basket, where ensuring the rubber gasket's tightness is crucial for a proper seal. However, traditional manual assembly methods are insufficient for efficient and stable production needs; therefore, there is an urgent need to develop a dedicated assembly tool to improve assembly efficiency and quality.

[0003] Under related technologies, refer to Figure 1 The cup lid has a slot inside, and a rubber pad needs to be installed in the slot. Then, the mirror basket is inserted into the slot. During assembly, it is usually done by manually pressing. First, press the rubber pad into the slot, and then press the mirror basket into the slot.

[0004] Regarding the aforementioned technologies, the conventional methods exhibit significant drawbacks in practical applications: manual operation is not only labor-intensive but also struggles to ensure uniform and consistent clamping force, easily leading to insufficient or damaged rubber gaskets, thus affecting the sealing performance of the neutralizing cup. Therefore, there is an urgent need for a solution that can automate and efficiently assemble the mirror basket and cup lid to overcome the shortcomings of existing technologies. Utility Model Content

[0005] In order to automate and efficiently assemble the mirror basket and the cup lid, this application provides an assembly fixture for a neutralization cup.

[0006] This application provides an assembly fixture for a neutralization cup, which adopts the following technical solution:

[0007] An assembly fixture for a neutralization cup, including

[0008] Frame;

[0009] A base is provided on the frame, and a placement groove is provided through the base along a first direction. The placement groove extends through the top wall of the base along a second direction, which is perpendicular to the first direction.

[0010] The pressing plate is located on the side of the base near the placement slot, and the pressing plate is slidably connected to the frame in the second direction;

[0011] A cylinder, the cylinder housing of which is fixedly connected to the frame, the piston rod of which is parallel to a first direction, and the piston rod of which is fixedly connected to the pressing plate.

[0012] By adopting the above technical solution, the rubber pad is inserted into the slot of the cup lid, and then the lens basket is inserted into the slot. In order to stably install the lens basket, rubber pad and slot, a base and a pressing plate are set. The cup lid product is placed in the placement slot, and the cylinder drives the pressing plate to slide in the first direction. The pressing plate contacts the lens basket and presses it towards the cup lid in the first direction, so that the rubber pad and lens basket can be stably installed in the slot of the cup lid. After installation, the operator places another cup lid in the placement slot. At this time, the previously installed cup lid is pushed to the outside of the placement slot. The lens basket is installed on the cup lid in the same way by pressing the plate. The steps are repeated to complete the assembly of the cup lid and lens basket. By pressing the plate, the rubber pad and cup lid can be assembled in place, thereby further improving the stability of the connection between the rubber pad and cup lid, as well as the stability of the connection between the lens basket and cup lid through automation.

[0013] Optionally, it also includes two limiting members, which are spaced apart along a third direction and have a clamping gap between them. The clamping gap and the placement groove are connected in a first direction.

[0014] By adopting the above technical solution, in order to further improve the stability of the cup lid in the placement slot and reduce the movement of the cup lid when the pressing plate presses the mirror basket, a limiting component is set. Two limiting components abut and limit the cup lid to be assembled, thereby improving the stability of the cup lid.

[0015] Optionally, the limiting element is a micro switch, and two micro switches are disposed on both sides of the base in the placement slot.

[0016] By adopting the above technical solution, and by setting the limiting component as a micro switch, the transmission element of the micro switch abuts against both sides of the cup lid to be operated. The transmission element limits the cup lid product, and the cylinder drives the pressing component to press the mirror basket. After installation, when the personnel push the subsequent cup lid, the installed cup lid applies force to the action spring of the micro switch. The action spring of the micro switch is displaced and moves away from the cup lid, so that the installed cup lid slides out of the placement groove. At this time, the two action springs return to their original positions.

[0017] Optionally, the base has a first receiving groove along the second direction, the first receiving groove is connected to the placement groove, and the limiting member is located in the first receiving groove.

[0018] By adopting the above technical solution, in order to make the limiting member abut against the cup lid, the limiting member is located in the first receiving groove, and the limiting member limits the cup lid.

[0019] Optionally, a sensor is installed on the frame, the sensor is electrically connected to the cylinder, and the sensor is located on the side of the limiting member away from the clamping gap.

[0020] By adopting the above technical solution, and by setting a sensor on the side of the limiting member away from the clamping gap, when the sensor senses that the cup lid is in the clamping gap, the sensor sends a signal to the cylinder, and the cylinder drives the pressing plate to slide along the first direction, thereby pressing the mirror basket into the slot of the cup lid for fixation, further improving the automation level of the overall assembly tooling.

[0021] Optionally, the base and the frame are fixed together by a locking assembly.

[0022] By adopting the above technical solution, in order to further improve the stability during installation, the base and the frame are fixed by locking components.

[0023] Optionally, a locking assembly is also included, which includes a screw and a pressure plate. The screw is parallel to the first direction, one end of the screw is rotatably connected to the frame, and the pressure plate is sleeved on the screw. The pressure plate slides along the length of the screw, and one side of the pressure plate is in contact with the top wall of the base.

[0024] By adopting the above technical solution, by setting a screw and a pressure plate, with the pressure plate sleeved on the screw, when the screw rotates, it drives the pressure plate to slide along the first direction, thereby fixing the base by the pressure plate and further improving the stability of the base.

[0025] Optionally, it also includes a guide rod, which is parallel to the screw, with one end of the guide rod fixedly connected to the frame, and the pressure plate sleeved on the guide rod.

[0026] By adopting the above technical solution, a guide rod is set to guide the rotation of the pressure plate along the screw.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. This application uses a base, a pressure plate, and a cylinder to place the cup lid product in the placement slot. The cylinder drives the pressing plate to slide in the first direction, so that the pressing plate contacts the mirror basket and presses it towards the cup lid in the first direction, so that the rubber pad and the mirror basket can be stably installed in the slot of the cup lid. After installation, the operator places another cup lid in the placement slot. At this time, the previously installed cup lid is pushed to the outside of the placement slot. The mirror basket is installed on the cup lid in the same way by pressing the plate. The steps are repeated to complete the assembly of the cup lid and the mirror basket, which further improves the convenience and stability of the connection between the mirror basket, the rubber pad, and the cup lid.

[0029] 2. This application uses a micro switch as the limiting component to further limit the cup lid to be installed;

[0030] 3. This application improves the stability of the base on the frame by setting a locking component and sliding the pressure plate along the length of the screw rod. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0037] This application discloses an assembly fixture for a neutralization cup. For ease of description, this application introduces directional terms such as first direction, second direction, and third direction to form a three-dimensional reference direction. The directional terms used, such as "first direction, second direction, and third direction," can be specifically referred to in the figure, where X represents the first direction X, Y represents the second direction Y, and Z represents the third direction Z. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0038] Reference Figure 1 The neutralizing cup includes a mirror basket 01, a cup lid 02, and a cup body (not shown in the figure). The cup lid 02 is detachably connected to the cup body. The cup lid 02 has a slot 03, and a rubber pad 04 is installed in the slot 03. After the rubber pad 04 is installed in the slot 03, the mirror basket 01 needs to be inserted into the slot 03 to complete the installation of the mirror basket 01 and the cup lid 02. The cup lid 02 has a circular cross-section.

[0039] Reference Figure 1 and Figure 2The assembly fixture for the neutralization cup includes a frame 1, a base 2, a pressing plate 3, and a cylinder 4. The base 2 is mounted on the frame 1, and a placement groove 21 is formed through the base 2 along a first direction. The placement groove 21 extends through the top wall of the base 2 along a second direction, which is perpendicular to the first direction. The pressing plate 3 is located on the side of the base 2 near the placement groove 21 and is slidably connected to the frame 1 along the second direction. The cylinder shell of the cylinder 4 is fixedly connected to the frame 1, and the piston rod of the cylinder 4 is parallel to the first direction and is fixedly connected to the pressing plate 3. The cup lid 02 is then placed on the base 1. Placed in the placement slot 21, the cylinder 4 drives the pressing plate 3 to slide along the first direction. The pressing plate 3 contacts the mirror basket 01 and presses it towards the cup lid 02 along the first direction, so that the rubber pad 04 and the mirror basket 01 can be stably installed in the slot 03 of the cup lid 02. After installation, the operator places another cup lid 02 in the placement slot 21. At this time, the previously installed cup lid 02 is pushed to the outside of the placement slot 21. The mirror basket 01 is installed on the cup lid 02 in the same way by pressing the plate 3. The steps are repeated to complete the assembly of the cup lid 02 and the mirror basket 01.

[0040] Reference Figure 3 When the pressing plate 3 presses the mirror basket 01, in order to further improve the stability of the cup lid 02 in the placement groove 21 and reduce the movement of the cup lid 02, the assembly tooling of the neutralizing cup also includes two limiting members 5. The two limiting members 5 are spaced apart along a third direction, which is perpendicular to both the first direction and the second direction. There is a clamping gap 51 between the two limiting members 5. The clamping gap 51 is connected to the placement groove 21 in the first direction. The cup lid 02 is located in the placement groove 21 and between the two limiting members 5, so that the cup lid 02 is limited by the two limiting members 5, reducing the impact of the movement of the cup lid 02 on the installation of the cup lid 02 and the mirror basket 01.

[0041] Reference Figure 3Specifically, the limiting component 5 is a micro switch. Two micro switches are tilted and symmetrically arranged relative to the cup lid 02. Micro switches are existing technology in this field. A micro switch is one in which external mechanical force acts on an actuating spring plate through a transmission element (button, lever, roller, etc.). In this application, the transmission element is a roller. When the actuating spring plate is displaced to the critical point, it generates an instantaneous action, causing the moving contact at the end of the actuating spring plate to connect or disconnect with the fixed contact. When the force on the transmission element is removed, the actuating spring plate generates a reverse action force. When the transmission element reverses, the actuating spring plate reaches its critical action point. After the point is pressed, the reverse action is completed instantly. In this embodiment, the transmission element of the micro switch, namely the roller, abuts against both sides of the cup lid 02 to be operated. The roller limits the cup lid 02 product. The cylinder 4 drives the pressing component to press the mirror basket 01. After installation, when the personnel push the subsequent cup lid 02, the installed cup lid 02 applies force to the action spring plate. The action spring plate is displaced and moves away from the cup lid 02, so that the installed cup lid 02 slides out of the placement groove 21. At this time, the two action spring plates return to their original positions. The micro switch is the prior art in this field, and the specific structure will not be described in detail here.

[0042] Reference Figure 3 In order to make the limiting member 5 abut against the cup lid 02, the base 2 is provided with a first receiving groove 22 along the second direction. The first receiving groove 22 is connected to the placement groove 21. The limiting member 5 is located in the first receiving groove 22 and the cup lid 02 is limited by the limiting member 5.

[0043] Reference Figure 3 To further improve the level of automation, a sensor 6 is installed on the frame 1. The sensor 6 is electrically connected to the cylinder 4. The sensor 6 is located on the side of the limiting member 5 away from the clamping gap 51. When the sensor 6 senses that the cup lid 02 is located in the clamping gap 51, the sensor 6 sends a signal to the cylinder 4. The cylinder 4 drives the pressing plate 3 to slide along the first direction, thereby pressing the mirror basket 01 into the slot 03 of the cup lid 02 for fixation.

[0044] Reference Figure 4 To further improve stability during installation, the base 2 and the frame 1 are fixed together by locking assembly 7.

[0045] Reference Figure 4Specifically, the frame 1 includes a fixedly connected mounting base 11 and mounting bracket 12. The cylinder shell of the cylinder 4 is fixedly connected to the mounting bracket 12. The base 2 is disposed on the mounting base 11. The locking assembly 7 includes a screw 71 and a pressure plate 72. The screw 71 is parallel to a first direction. One end of the screw 71 is rotatably connected to the mounting plate. The screw 71 is parallel to the first direction along the rotation axis of the mounting plate. The pressure plate 72 is sleeved on the screw 71. The pressure plate 72 slides along the length of the screw 71. One side of the pressure plate 72 is in contact with the top wall of the base 2. When the screw 71 is rotated, the screw 71 drives the pressure plate 72 to slide along the first direction, thereby pressing the base 2 tightly and ensuring the stability between the base 2 and the mounting base 11. In this embodiment, the locking assembly 7 is spaced apart on both sides of the mounting base 11 along a third direction.

[0046] Reference Figure 4 In order to guide the sliding of the pressure plate 72 along the length of the screw 71, the assembly tooling of the neutralization cup also includes a guide rod 8. The guide rod 8 is parallel to the screw 71, and one end of the guide rod 8 is fixedly connected to the base 2. The pressure plate 72 is sleeved on the guide rod 8, and the guide rod 8 guides the sliding of the pressure plate 72 along the length of the screw 71.

[0047] The implementation principle of the assembly tooling for a neutralization cup in this application embodiment is as follows: Before assembly, the base 2 is placed on the mounting seat 11 of the frame 1, and the screw 71 is rotated to drive the pressure plate 72 to slide along the first direction so that the pressure plate 72 fixes the base 2.

[0048] During assembly, the cup lid 02 is placed in the placement slot 21. When the cup lid 02 to be assembled moves to the limiting member 5, the sensor 6 sends a signal to the cylinder 4. The cylinder 4 drives the pressing plate 3 to slide along the first direction. The pressing plate 3 contacts the mirror basket 01 and presses it towards the cup lid 02 in the first direction so that the rubber pad 04 and the mirror basket 01 can be stably installed in the slot 03 of the cup lid 02. After installation, the operator places another cup lid 02 in the placement slot 21. At this time, the previously installed cup lid 02 is pushed to the outside of the placement slot 21. The mirror basket 01 is installed on the cup lid 02 in the same way by pressing the plate 3. The steps are repeated to complete the assembly of the cup lid 02 and the mirror basket 01.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
