Description

Technical Field

[0001] This utility model relates to the field of packaging fixture technology, and more specifically, to a universal fixture assembly for probe housing packaging. Furthermore, this utility model also relates to a fixture including the aforementioned universal fixture assembly for probe housing packaging. Background Technology

[0002] The outer shell of an in vitro diagnostic probe, such as an ultrasound probe shell, is generally composed of two halves bonded together with adhesive. During encapsulation, a clamping assembly is used to clamp the shell from both sides, and then the adhesive is allowed to cure.

[0003] However, in actual production, the shape of the ultrasonic probe shell is an irregular curved surface. In order to ensure that the shell can be tightly joined during the ultrasonic probe packaging process, the clamping assembly needs to be in close contact with and pressed against the ultrasonic probe shell. Therefore, the contact surface of the clamping assembly should be the same as the curved surface of the ultrasonic probe shell. Thus, a corresponding clamping assembly needs to be made for each ultrasonic probe packaging, which increases the production cost.

[0004] In the prior art, a method is disclosed that uses a floating pin to automatically adapt to the curved surface of the probe housing to ensure that the clamping assembly can make close contact with the ultrasonic probe housing. However, during the curing process of the adhesive on the housing, the adhesive has a certain fluidity and requires a certain curing time. The flowing adhesive will adhere to the floating pin, causing the pin to lose its floating performance. When adapting to a new probe housing, it cannot make close contact with the curved surface of the probe housing, making the clamping assembly unusable.

[0005] In summary, how to solve the problem of flowing adhesive adhering to floating ejector pins, causing the ejector pins to lose their floating properties, is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a universal clamping assembly for probe housing packaging. By adding a fan to generate airflow and constraining the airflow direction through air holes, the airflow can effectively act on the workpiece, accelerate the curing of the adhesive, avoid the loss of the ejector pin's floating performance caused by the adhesive adhering to the ejector pin, and enable the clamping assembly to be reusable.

[0007] Another objective of this invention is to provide a clamp that includes the aforementioned universal clamping assembly for probe housing encapsulation, possessing the same technical features and capable of solving the same technical problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A fan is fixedly disposed relative to the top block. The surface of the top block base is provided with air holes for the airflow generated by the fan to act on the workpiece shell that is abutted by the ejector pin.

[0012] Preferably, the surface of the top block substrate is provided with pin holes and air holes at intervals. The pin holes are used to slide the pins, and the airflow discharged from the air holes can act on the pins in the pin holes near the pins.

[0013] Preferably, the probe housing encapsulates a universal clamping assembly and further includes a heating assembly, which is arranged within the air duct where the fan and / or the air hole are located, for heating the airflow discharged from the air hole.

[0014] Preferably, the ejector pin includes a driving component for driving the ejector pin to move in the same direction relative to the top block substrate.

[0015] Preferably, the driving component includes a counterweight block, which is fixedly disposed at one end of the ejector pin located inside the ejector block;

[0016] When the ejector pin is vertical, the counterweight can drive the ejector pin to slide downward relative to the ejector block.

[0017] Preferably, the locking assembly includes a locking hole plate and a locking bolt;

[0018] The locking plate includes several through holes, the ejector pin passes through the through holes, and the locking bolt is threadedly connected to the top block to abut and drive the locking plate to move radially along the ejector pin, so that the side wall of the ejector pin can abut and brake against the wall of the through hole.

[0019] Preferably, the cross-sectional area of ​​the through hole is larger than the cross-sectional area of ​​the ejector pin, in order to reduce the relative motion resistance between the ejector pin and the through hole when they are not in contact during braking.

[0020] Preferably, the top block comprises two layers of perforated plates, each perforated plate being provided with pin holes, and the locking perforated plate being slidably disposed between the two layers of perforated plates;

[0024] The universal clamping assembly for probe housing encapsulation provided by this utility model has at least the following advantages compared with the prior art:

[0025] By adding a fan to generate airflow, and restricting the airflow direction through the pores on the surface of the top block substrate, the airflow is effectively directed to the workpiece shell that the ejector pin abuts, promoting the curing of the adhesive used during the encapsulation of the probe shell, reducing adhesive flow, and thus preventing adhesive from adhering to the ejector pin, maintaining the ejector pin's floating ability, and ensuring that the fixture assembly remains reusable.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] The core of this utility model is to provide a universal clamping assembly for probe housing packaging. By adding a fan to generate airflow and constraining the airflow direction through air holes, the airflow can effectively act on the workpiece, accelerate the curing of the adhesive, avoid the loss of the ejector pin's floating performance caused by the adhesive adhering to the ejector pin, and enable the clamping assembly to be reusable.

[0040] Another core aspect of this utility model is to provide a clamp that includes the aforementioned universal clamping assembly for probe housing encapsulation, which has the same technical features and can solve the same technical problems.

[0041] Please refer to Figures 1-4 A universal clamping assembly for encapsulating a probe housing includes:

[0042] The top block includes a top block base 21, a number of ejector pins 22 that are floatingly connected to the inside of the top block base 21, and a locking assembly 23 for locking the position of the ejector pins 22. One end of the ejector pins 22 extends to the outside of the top block base 21 and is used to abut against the workpiece shell.

[0043] The fan 4 is fixed relative to the top block. The surface of the top block base 21 is provided with air holes 212, which are used to allow the airflow generated by the fan 4 to act on the workpiece shell that is abutted by the ejector pin 22 through the air holes 212.

[0044] like Figure 1As shown, several sets of ejector pins 22 are floating inside the top block. Before clamping the probe housing 1, the ends of the ejector pins 22 extending to the outside of the top block base 21 are all made to abut against the surface of the probe housing 1. At this time, the locking assembly 23 is used to lock all the ejector pins 22 so that they cannot float. At this time, all the ejector pins 22 have a relatively fixed positional relationship with the top block, and the ends of the ejector pins 22 extending to the outside of the top block replicate the surface of the probe housing 1. They can still maintain good contact and abutment with other probe housings 1 of the same shape. When the probe housing 1 is replaced, the locking assembly 23 is operated to release the locking of the ejector pins 22, so that the ejector pins 22 restore their original floating ability. The above steps of replicating the surface of the probe housing 1 are repeated so that the clamping assembly 2 can be re-applied to clamp the new probe housing 1.

[0045] Meanwhile, the fan 4, which is fixed to the clamping assembly 2, drives the airflow. At the same time, the air hole 212 is provided in the top block base 21 to restrict the direction of airflow, so that the airflow can effectively act on the surface of the probe shell 1 held by the ejector pin 22. The airflow acts on the surface of the adhesive used for sealing the probe shell 1, which promotes the rapid curing of the adhesive and reduces the fluidity of the adhesive. This prevents the ejector pin 22 from losing its floating ability due to the adhesive adhering to the ejector pin 22. That is, after the clamping assembly 2 completes the clamping and the locking assembly 23 unlocks the ejector pin 22, the ejector pin 22 can restore its original floating ability and can be used again to replicate the surface of a new probe shell 1.

[0046] In some embodiments, the surface of the top block substrate 21 is provided with ejector pin holes 211 and vent holes 212 at intervals. The ejector pin holes 211 are used for slidingly mounting ejector pins 22, and the airflow discharged from the vent holes 212 can act on the ejector pins 22 in the ejector pin holes 211 near itself. It is understood that the embodiments mentioned above have a broader protective effect on the ejector pins 22 as a whole and prevent adhesion. In some other embodiments, top block substrates 21 with different vent hole distribution positions can be selected to concentrate the vent holes 212 on the outer side, thereby accelerating the curing of the adhesive coating at the edge of the shell. The distribution of the vent holes 212 can be adaptively adjusted according to actual needs and the shape of the shell to be packaged, but all of these are beyond the protection scope of this application.

[0047] like Figure 2 As shown, the air holes 212 and the pin holes 211 are evenly spaced. The air holes 212 are used for airflow guidance, and the pin holes 211 are used for guiding the pin 22. The airflow in the air holes 212 blows from the root of the pin 22 to the end of the pin 22 until it acts on the surface of the probe housing 1 held at the end of the pin 22. This can inhibit the flow of adhesive along the outer wall of the pin 22 from the end to the root, thereby preventing the adhesive from solidifying at the contact position between the pin 22 and the pin hole 211, that is, preventing the pin 22 from sticking to the pin hole 211.

[0048] Meanwhile, for moisture-curing silicone, the flowing airflow acts on the adhesive, which can accelerate the curing of the adhesive and shorten the encapsulation time of the workpiece.

[0049] In some embodiments, the probe housing encapsulates a general-purpose clamping assembly and also includes a heating assembly 5, which is arranged in the air duct where the fan 4 and the air hole 212 are located, for heating the airflow discharged from the air hole 212.

[0050] like Figure 1 As shown, a heating component 5 is installed in the air duct where the fan 4 and / or the air hole 212 are located to heat the airflow, thereby increasing the temperature of the airflow acting on the surface of the probe housing 1. For the probe housing 1 encapsulated with epoxy resin, the high-temperature airflow can accelerate the curing of the resin and further shorten the encapsulation time.

[0051] In some embodiments, the ejector pin 22 includes a driving component for driving the ejector pin 22 to move in the same direction relative to the top block base 21.

[0052] By setting a driving component, the ejector pin 22 has a driving force in the same direction when it is floating. This ensures that when the ejector pin 22 comes into contact with the surface of the probe housing 1, the end of the ejector pin 22 can effectively contact the probe housing 1, avoiding the problem that some ends of the ejector pin 22 do not effectively contact the probe housing 1. This ensures that the shape formed by the ends of all the ejector pins 22 is consistent with the shape of the clamping surface of the probe housing 1, and that when the clamping assembly 2 clamps the probe housing 1, the ends of the ejector pins 22 can fit tightly against the probe housing 1, so that the probe housing 1 is subjected to a balanced clamping force at all positions.

[0053] In some embodiments, the drive component includes a counterweight 221, which is fixedly disposed at one end of the ejector pin 22 located inside the ejector pin;

[0054] When the ejector pin 22 is vertical, the counterweight 221 can drive the ejector pin 22 to slide outward.

[0055] like Figure 4 As shown, a counterweight 221 is provided at the root of the ejector pin 22. When the clamp assembly 2 is in the position where the end of the ejector pin 22 is facing down, the counterweight 221 can drive the ejector pin 22 to move along its own axis towards the end under the action of gravity until the end of the ejector pin 22 is blocked and stops moving. This ensures that when replicating the surface of the probe housing 1, the end of the ejector pin 22 can effectively contact the surface of the housing, thereby ensuring that the replica surface is consistent with the surface of the probe housing 1.

[0056] In some embodiments, the locking assembly 23 includes a locking hole plate 231 and a locking bolt 232;

[0057] The locking plate 231 includes several through holes, through which the ejector pin 22 passes. The locking bolt 232 is connected to the top block by a thread and is used to abut against and drive the locking plate 231 to move radially along the ejector pin 22, so that the side wall of the ejector pin 22 can abut against and brake the wall of the through hole.

[0058] like Figure 4 and Figure 5 As shown, the locking assembly 23 includes a locking hole plate 231 and a locking bolt 232. The ejector pin 22 passes through the through hole of the locking hole plate 231. When the locking assembly 23 is in the unlocked state, there is a small positive pressure between the side wall of the ejector pin 22 and the hole wall of the through hole, which makes the axial movement resistance of the ejector pin 22 small. When the locking hole plate 231 moves under the drive of the locking bolt 232, that is, the locking hole plate 231 moves radially along the ejector pin 22, the positive pressure between the side wall of the ejector pin 22 and the hole wall of the through hole increases, and the friction between the side wall of the ejector pin 22 and the hole wall of the through hole increases, that is, the axial movement resistance of the ejector pin 22 increases, thereby locking the position of the ejector pin 22, and thus making the ends of all the ejector pins 22 jointly used to replicate the clamping surface of the probe housing 1.

[0059] In some embodiments, the cross-sectional area of ​​the through hole is larger than the cross-sectional area of ​​the ejector pin 22, in order to reduce the relative motion resistance between the ejector pin 22 and the through hole in the non-contact braking state.

[0060] like Figure 4 and Figure 5 As shown, the cross-sectional area of ​​the ejector pin hole 211 of the clamping assembly 2 is similar to or the same as the cross-sectional area of ​​the ejector pin 22, which provides good guiding performance for the ejector pin 22. The cross-sectional area of ​​the through hole of the locking plate 231 is larger than that of the ejector pin 22, so that when the locking plate 231 is in the non-locked state, there is a gap between the outer peripheral wall of the ejector pin 22 and the wall of the through hole. That is, the wall of the through hole of the locking plate 231 and the outer peripheral wall of the ejector pin 22 do not have direct contact, thereby reducing the resistance to the axial movement of the ejector pin 22 and improving the floating performance of the ejector pin 22.

[0061] In some embodiments, the top block includes two layers of perforated plates, the perforated plates being provided with pin holes 211, and the locking perforated plate 231 being slidably disposed between the two layers of perforated plates;

[0062] The ejector pin 22 passes through both the ejector pin hole 211 of the two perforated plates and the through hole of the locking perforated plate 231. More preferably, based on the previous embodiment, when the ejector pin hole 211 and the locking perforated plate 231 are not coaxial in the vertical direction, that is, when the locking perforated plate 231 is offset relative to the ejector pin hole 211, the side wall of the ejector pin 22 can abut against the wall of the through hole of the ejector pin hole 211 for braking.

[0063] like Figure 4 and Figure 5As shown, a double-layer perforated plate is used inside the top block to guide the ejector pin 22, ensuring the stability of the ejector pin 22's movement trajectory. At the same time, the locking plate 231 is slidably set between the two layers of perforated plates. When the locking plate 231 is in the locked position, there are three contact points a, b, and c between the ejector pin hole 211 of the two layers of perforated plates and the through hole wall of the locking plate 231 and the outer peripheral wall of the ejector pin 22. Points a, b, and c are located on both sides symmetrical about the central surface of the ejector pin 22, and point c is located between points a and b. This balances the radial force on the ejector pin 22 as a whole, preventing the occurrence of overturning torque.

[0064] In addition to the universal clamping assemblies for probe housing encapsulation disclosed in the above embodiments, this utility model also provides a clamping device, including at least two sets of universal clamping assemblies for probe housing encapsulation of any one of the above embodiments, all of which are capable of moving towards or away from each other, for clamping or releasing the probe housing 1.

[0065] like Figure 5 As shown, the clamping and releasing of the probe housing 1 by the opposing or opposite movements of multiple clamping assemblies 2 are achieved.

[0066] In some embodiments, the clamp further includes a frame 3, the clamp assemblies being slidably mounted relative to the frame 3, and the frame 3 being provided with a power assembly that drives all clamp assemblies to move toward or away from each other.

[0067] like Figure 5 As shown, the clamp assembly 2 and the frame 3 are slidably installed to ensure the stability of the movement trajectory of the clamp assembly 2. At the same time, a power component is added to ensure that the clamping force of the clamp assembly 2 on the probe housing 1 is stable.

[0068] The structure of the other parts of the fixture is described in reference to existing technologies and will not be repeated here.

[0069] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
