Description

Technical Field

[0001] This application relates to the field of disassembly and assembly tooling technology, and more specifically to a lamp tube disassembly and assembly tooling. Background Technology

[0002] The heating lamp contains a large number of individual lamp tubes. The lifespan of each lamp tube is affected by the number of times it is switched on and off and the duration of illumination. When it is damaged at random times, it needs to be replaced individually in a timely manner. However, there is currently a lack of dedicated disassembly and assembly tools. Usually, simple tools such as water pipes are used to disassemble the lamp tubes, which easily leads to disassembly and assembly failure. Failure to disassemble and assemble may cause the lamp tube to break and cause extensive contamination of the chamber where the heating lamp is located.

[0003] Therefore, improvements are needed to at least partially address the aforementioned problems. Utility Model Content

[0006] A disassembly / assembly component, comprising a plug-in section and a gripping section connected to the plug-in section, the plug-in section having a lamp slot;

[0007] A pressure adjustment assembly is connected to the lamp slot. The pressure adjustment assembly is used to generate negative pressure in the lamp slot when the lamp is inserted into the lamp slot, so as to fix the lamp in the lamp slot.

[0008] For example, the disassembly component further includes a gripping section connected to the plug-in section, the gripping section having an air passage, and the pressure adjustment component communicating with the lamp slot through the air passage.

[0010] For example, the plug segment is used to at least partially insert into the lamp mounting slot;

[0011] The outer side of the assembly / disassembly component is provided with a limiting boss.

[0012] For example, the pressure adjustment component is also used to generate a normal pressure or a positive pressure in the lamp slot when the lamp is inserted into the lamp slot, so that the lamp can be separated from the lamp slot.

[0015] For example, the pressure adjustment assembly further includes a first pressure regulating device and a second pressure regulating device;

[0016] The first pressure regulating device is disposed between the negative pressure output end and the first end of the three-way valve, and is used to regulate the pressure of the negative pressure output by the negative pressure output end;

[0017] The second pressure regulating device is disposed between the positive pressure output terminal and the second end of the three-way valve, and is used to regulate the pressure of the positive pressure output by the positive pressure output terminal.

[0018] For example, the first pressure regulating device includes a pressure gauge and a pressure regulating valve; and / or,

[0020] For example, the pressure adjustment assembly includes a positive and negative pressure generator and a connecting pipe;

[0021] The positive and negative pressure output terminals of the positive and negative pressure generator are connected to the lamp slot through the connecting pipe.

[0022] For example, the pressure adjustment assembly further includes a pressure regulating device disposed between the positive and negative pressure output terminals and the lamp slot, for adjusting the pressure of the positive pressure output by the positive and negative pressure output terminals or the pressure of the negative pressure output by the positive and negative pressure output terminals.

[0023] According to the lamp installation and removal tool of this application, when removing a lamp, the lamp can be inserted into a lamp slot, and then a negative pressure is generated in the lamp slot by a pressure adjusting component to fix the lamp in the lamp slot. The connector section, along with the lamp, is then removed from the lamp mounting slot. When installing a lamp, the lamp can be inserted into a lamp slot, and then a negative pressure is generated in the lamp slot by a pressure adjusting component to fix the lamp in the lamp slot.

[0040] See attached document Figure 1-5An exemplary description is provided for a lamp tube disassembly and assembly tool according to an embodiment of this application, which includes a disassembly and assembly component 100 and a pressure adjustment assembly 200.

[0041] The disassembly / removal component 100 includes a plug-in section 110 and a gripping section 120 connected to the plug-in section 110. The plug-in section 110 has a lamp slot 111 for inserting a lamp 10 to be disassembled / removed. In this embodiment, the plug-in section 110 is used to at least partially insert into the lamp mounting slot 21, thereby allowing the lamp 10 located in the lamp mounting slot 21 to be inserted into the lamp slot 111, and allowing the lamp 10 to be inserted into the lamp mounting slot 21 while it is already inserted into the lamp slot 21. The gripping section 120 is provided with an air passage 121, the first end of which communicates with the bottom of the lamp slot 111. The gripping section 120 is used for an operator to hold, so that the operator can use the disassembly / removal component 100 to disassemble / remove the lamp 10. In some other embodiments, when the lamp tube 10 installed in the lamp tube mounting groove 21 partially protrudes outside the lamp tube mounting groove 21 (that is, the lamp tube 10 is not completely located in the lamp tube mounting groove 21), the plug section 110 may not be inserted into the lamp tube mounting groove 21 during the installation and removal of the lamp tube 10.

[0042] The pressure adjustment component 200 is connected to the second end of the air passage 121, and is also connected to the lamp slot 111 via the air passage 121. The pressure adjustment component 200 generates a negative pressure within the lamp slot 111 when the lamp 10 is inserted into it, thus securing the lamp 10 in the slot. When a negative pressure is generated within the lamp slot 111, the external air pressure is greater than the air pressure within the slot, and this pressure difference allows the lamp 10 to be firmly adhered and fixed in the slot. The pressure adjustment component 200 also generates a positive pressure within the lamp slot 111 when the lamp 10 is inserted into it, thus separating the lamp 10 from the slot. When a positive pressure is generated within the lamp slot 111, the external air pressure is less than the air pressure within the slot, and this pressure difference can push the lamp 10 out of the slot.

[0043] Therefore, when disassembling the lamp tube 10, the operator can hold the gripping section 120 and insert the plug section 110 into the lamp tube mounting slot 21, so that the lamp tube 10 in the lamp tube mounting slot 21 is inserted into the lamp tube slot 111. Then, the pressure adjusting component 200 generates negative pressure in the lamp tube slot 111 to fix the lamp tube 10 in the lamp tube slot 111. Then, the operator can hold the gripping section 120 to remove the plug section 110 along with the lamp tube 10 from the lamp tube mounting slot 21. When installing the lamp tube 10, the lamp tube 10 can be inserted into the lamp tube slot 111. 11. Then, negative pressure is generated in the lamp slot 111 by the pressure adjustment component 200 to fix the lamp 10 in the lamp slot 111. Then, the insertion section 110 along with the lamp 10 is inserted into the lamp mounting groove 21 by holding the gripping section 120, so that the lamp 10 is installed in the lamp mounting groove 21. Then, positive pressure is generated in the lamp slot 111 by the pressure adjustment component 200 to separate the lamp 10 from the lamp slot 111. At the same time, the insertion section 110 is pulled out of the lamp mounting groove 21 by holding the gripping section 120. The lamp disassembly and assembly tool according to this application can safely and conveniently disassemble and assemble lamps, significantly improving the success rate of lamp disassembly.

[0044] In some embodiments, the disassembly / removal component 100 may only include the insertion section 110 without the gripping section 120. That is, the disassembly / removal component 100 includes the insertion section 110, which has a lamp slot 111 for inserting a lamp 10 to be disassembled / removed. The insertion section 110 can be used to at least partially insert into the lamp mounting slot 21. The pressure adjustment component 200 communicates with the lamp slot 111 and is used to generate a negative pressure in the lamp slot 111 when the lamp 10 is inserted into the lamp slot 111, so as to fix the lamp 10 in the lamp slot 111. When disassembling the lamp tube, the connector 110 can be inserted into the lamp tube mounting slot 21, so that the lamp tube 10 in the lamp tube mounting slot 21 is inserted into the lamp tube slot 111. Then, the pressure adjustment component 200 generates negative pressure in the lamp tube slot 111 to fix the lamp tube 10 in the lamp tube slot 111. Then, the connector 110 together with the lamp tube 10 is removed from the lamp tube mounting slot 21. When installing the lamp tube 10, the lamp tube 10 can be inserted into the lamp tube slot 111. Then, the pressure adjustment component 200 generates negative pressure in the lamp tube slot 111 to fix the lamp tube 10 in the lamp tube slot 111. Then, the connector 110 together with the lamp tube 10 is inserted into the lamp tube mounting slot 21 to install the lamp tube 10 in the lamp tube mounting slot 21. For example, the pressure adjustment assembly 200 is also used to generate a normal or positive pressure in the lamp slot 111 when the lamp tube 10 is inserted into the lamp slot 111, so that the lamp tube 10 can be separated from the lamp slot 111. For example, after inserting the connector 110 together with the lamp tube 10 into the lamp mounting slot 21 and installing the lamp tube 10 in the lamp mounting slot 21, the pressure adjustment assembly 200 can be controlled to stop generating negative pressure and generate a normal pressure in the lamp slot 111 (e.g., by depressurization), so that the lamp tube 10 is no longer fixed in the lamp slot 111, so that the connector 110 can be removed from the lamp mounting slot 21. It should be noted that when the pressure adjustment assembly 200 generates a normal pressure in the lamp slot 111, the operator needs to manually separate the connector 110 from the lamp tube 10 and remove it from the lamp mounting slot 21. For example, after inserting the connector 110 along with the lamp tube 10 into the lamp tube mounting slot 21, and installing the lamp tube 10 in the lamp tube mounting slot 21, positive pressure can be generated in the lamp tube slot 111 by the pressure adjustment component 200, so that the lamp tube 10 is separated from the lamp tube slot 111 under pressure. In this way, the connector 110 and the lamp tube 10 can be separated more easily, and the connector 110 can be removed from the lamp tube mounting slot 21. In some other embodiments, when the lamp tube 10 installed in the lamp tube mounting slot 21 partially protrudes outside the lamp tube mounting slot 21 (that is, the lamp tube 10 is not completely located in the lamp tube mounting slot 21), the connector 110 may not be inserted into the lamp tube mounting slot 21 during the installation and removal of the lamp tube 10.

[0045] See appendix Figures 1-4In this embodiment, a flexible buffer layer 130 is provided on the inner wall of the lamp slot 111. A through hole is provided in the flexible buffer layer 130 at the position corresponding to the first end of the air passage 121. By providing the flexible buffer layer 130 on the inner wall of the lamp slot 111, a tight fit can be achieved between the lamp 10 and the lamp slot 111, enhancing the sealing performance, while also preventing the lamp 10 from breaking due to contact and compression between the insertion section 110 and the lamp 10. In this embodiment, one end of the lamp 10 has a glass head 11, and the shape of the lamp slot 111 matches the shape of the glass head 11. The lamp slot 111 is used for inserting the glass head 11 of the lamp 10. The flexible buffer layer 130 effectively prevents the glass head 11 from breaking during insertion into and removal from the lamp slot 111, ensuring safety during assembly and disassembly. In other embodiments, one end of the lamp 10 may not have a glass head 11, and the shape of the lamp slot 111 may directly match the shape of the end of the lamp 10. In some other embodiments, for high-strength lamps, the inner wall of the lamp slot 111 may not be provided with a flexible buffer layer 130.

[0046] For example, the flexible buffer layer 130 may be a rubber layer, a sponge layer, or a foam plastic layer, which may be fixed to the inner wall of the lamp slot 111 by means such as adhesive. The flexible buffer layer 130 may also be other material layers known to those skilled in the art, which have a certain deformation capability and can form a good buffer layer between the inner wall of the lamp slot 111 and the lamp 10.

[0047] For example, in this embodiment, the grip section 120 is generally cylindrical. In other embodiments, the grip section 120 may have other shapes similar to a handle. The outer surface of the grip section 120 may be provided with an anti-slip pattern, which may be regular linear protrusions or grooves, or it may be uniformly distributed granular protrusions. In this embodiment, the end of the lamp tube slot 111 away from the grip section 120 is a flared opening, that is, its inner diameter gradually increases along the direction in which the lamp tube 10 is inserted into the lamp tube slot 111. This arrangement facilitates the insertion of the lamp tube 10 into the lamp tube slot 111.

[0048] See appendix Figure 1 , Figure 2 and Figure 4In this embodiment, the plug-in segment 110 is used to at least partially insert into the lamp mounting slot 21, and a limiting boss is provided on the outer side of the disassembly / assembly component 100. The limiting boss 140 is used to abut against the outer end face of the lamp mounting slot 21 when the plug-in segment 110 is inserted into the lamp mounting slot 21 in the lamp nest 20, preventing the limiting boss 140 from entering the lamp mounting slot 21. The setting of the limiting boss 140 can ensure that the depth of the plug-in segment 110 entering the lamp mounting slot 21 is fixed each time, avoiding excessive insertion that could cause the lamp 10 to break due to excessive squeezing pressure. The limiting boss 140 can be an annular boss, circumferentially arranged on the outer peripheral surface, or the limiting boss 140 can be multiple protrusions spaced apart on the outer peripheral surface. In this embodiment, the limiting boss 140 is provided on the outer side of the connection between the plug-in segment 110 and the gripping segment 120. It should be noted that the term "outer side" at the connection between the insertion segment 110 and the gripping segment 120 can refer only to the outer side of the end of the insertion segment 110 near the gripping segment 120, or only to the outer side of the end of the gripping segment 120 near the insertion segment 110, or simultaneously to both the outer sides of the ends of the insertion segment 110 and the gripping segment 120. That is, the limiting boss 140 can be located only on the outer peripheral surface of the end of the insertion segment 110 near the gripping segment 120, or only on the outer peripheral surface of the end of the gripping segment 120 near the insertion segment 110, or simultaneously on both the outer sides of the end of the insertion segment 110 and the gripping segment 120. In some embodiments, when the disassembly / assembly component 100 does not have a gripping segment 120, the limiting boss 140 is located on the outer side of the insertion segment 110. In some embodiments, the limiting boss 140 itself can serve as a gripping part in the disassembly assembly 100.

[0049] In some other embodiments, the limiting boss 140 may not be provided. Instead, a mark (e.g., a line or arrow pattern) may be provided on the outside of the connection between the plug segment 110 and the holding segment 120. When the plug segment 110 is inserted into the lamp mounting slot 21, the insertion depth is determined by observing the position of the mark. For example, when the mark is flush with the outer end face of the lamp mounting slot 21, it is determined that the plug segment 110 has been inserted to the appropriate depth.

[0050] For example, in this embodiment, the insertion segment 110, the gripping segment 120, and the limiting boss 140 can be integrally formed, for example, by injection molding. In other embodiments, the insertion segment 110, the gripping segment 120, and the limiting boss 140 can be separate parts, which are fixedly connected to form a whole by means such as bonding or welding.

[0051] See appendix Figure 1In this embodiment, the pressure adjustment assembly 200 includes a positive and negative pressure generator 210, a three-way valve 220, a first connecting pipe 230, a second connecting pipe 240, a third connecting pipe 250, a first pressure regulating device 260, and a second pressure regulating device 270.

[0052] The positive and negative pressure generator 210 has a negative pressure output terminal and a positive pressure output terminal, and can output negative pressure and positive pressure respectively through the negative pressure output terminal and the positive pressure output terminal. For example, the positive and negative pressure generator 210 may include a vacuum pump and a booster pump, with the vacuum pump connected to the negative pressure output terminal and the booster pump connected to the positive pressure output terminal. It should be noted that outputting negative pressure through the negative pressure output terminal means evacuating the object connected to it through the negative pressure output terminal to generate negative pressure inside the connected object. For example, the negative pressure output terminal and the positive pressure output terminal can be the air inlet and air outlet of the positive and negative pressure generator 210, respectively.

[0053] The negative pressure output end of the positive and negative pressure generator 210 is connected to the first end of the three-way valve 220 through the first pressure regulating device 260 and the first connecting pipe 230. The positive pressure output end of the positive and negative pressure generator 210 is connected to the second end of the three-way valve 220 through the second pressure regulating device 270 and the second connecting pipe 240. The third end of the three-way valve 220 is connected to the lamp slot 111 through the third connecting pipe 250. Specifically, in this embodiment, the third connecting pipe 250 is connected to the second end of the air passage 121, and the third end of the three-way valve 220 is connected to the lamp slot 111 through the third connecting pipe 250 and the air passage 121. In some other embodiments, when the disassembly and assembly part 100 does not have a grip section 120, the third connecting pipe 250 can be connected to the bottom of the lamp slot 111, and the third end of the three-way valve 220 is directly connected to the lamp slot 111 through the third connecting pipe 250.

[0054] In this embodiment, the first pressure regulating device 260 is disposed between the negative pressure output end of the positive and negative pressure generator 210 and the first connecting pipe 230. In some other embodiments, the first pressure regulating device 260 may also be disposed between the first connecting pipe 230 and the first end of the three-way valve 220. The first pressure regulating device 260 is used to regulate the pressure of the negative pressure output from the negative pressure output end. The positive and negative pressure generator 210 can usually only output fixed negative and positive pressures, which may be too high or too low, making it difficult to meet the disassembly and assembly requirements of the lamp tube 10 (for example, if the negative pressure is too high, it may damage the lamp tube 10; if the negative pressure is too low, the lamp tube 10 may fall off during disassembly and assembly due to insecure fixing). This application can adjust the negative pressure output by the positive and negative pressure generator 210 (that is, the negative pressure value in the lamp tube slot 111) to a suitable range by setting the first pressure regulating device 260, so as to fully meet the installation requirements. For example, the first pressure regulating device 260 may include a pressure gauge and a pressure regulating valve. The pressure regulating valve is used to regulate the negative pressure output from the negative pressure output terminal, and the pressure gauge is used to display the adjusted negative pressure (i.e., the negative pressure value within the lamp slot 111). By using the pressure gauge and pressure regulating valve, the negative pressure can be adjusted to a suitable value (e.g., a fixed parameter) each time the lamp 10 is disassembled or assembled, facilitating the standardization and normalization of disassembly and assembly operations and avoiding disassembly / assembly failures due to differences in operator technique or experience. In some embodiments, the first pressure regulating device 260 may only include a pressure regulating valve, which, by adjusting the opening degree, adjusts the negative pressure value to a suitable range.

[0055] Similarly, in this embodiment, the second pressure regulating device 270 is disposed between the positive pressure output terminal of the positive and negative pressure generator 210 and the second connecting pipe 240. In some other embodiments, the second pressure regulating device 270 may also be disposed between the second connecting pipe 240 and the second end of the three-way valve 220. The second pressure regulating device 270 is used to regulate the pressure of the positive pressure output from the positive pressure output terminal. Exemplarily, the second pressure regulating device 270 may include a pressure gauge and a pressure regulating valve. In some embodiments, the second pressure regulating device 270 may only include a pressure regulating valve.

[0056] For example, the first connecting pipe 230, the second connecting pipe 240 and the third connecting pipe 250 can be flexible hoses, which can effectively facilitate the operation of the operator.

[0057] In some other embodiments, when the negative pressure output from the negative pressure output terminal and the positive pressure output from the positive pressure output terminal of the positive and negative pressure generator 210 can directly meet the disassembly and assembly requirements of the lamp tube 10, the first pressure regulating device 260 and the second pressure regulating device 270 may not be provided in the pressure adjustment assembly 200. That is, the pressure adjustment assembly 200 may include the positive and negative pressure generator 210, the three-way valve 220, the first connecting pipe 230, the second connecting pipe 240, and the third connecting pipe 250. The negative pressure output terminal of the positive and negative pressure generator 210 is connected to the first end of the three-way valve 220 through the first connecting pipe 230, the positive pressure output terminal of the positive and negative pressure generator 210 is connected to the second end of the three-way valve 220 through the second connecting pipe 240, and the third end of the three-way valve 220 is connected to the lamp tube slot 111 through the third connecting pipe 250.

[0058] In other embodiments, the pressure adjustment assembly 200 may include a positive or negative pressure generator, a connecting pipe, and a pressure regulating device.

[0059] The positive and negative pressure generator has positive and negative pressure output terminals that can switch between outputting negative pressure and outputting positive pressure. For example, the positive and negative pressure generator may include a bidirectional air pump that generates negative pressure when rotating forward and generates positive pressure when rotating in reverse. The bidirectional air pump is connected to the positive and negative pressure output terminals, through which negative pressure or positive pressure is output.

[0060] The positive and negative pressure output terminals of the positive and negative pressure generator are connected to the lamp slot 111 via connecting pipes and a pressure regulating device. The pressure regulating device is used to adjust the pressure of the negative or positive pressure output from the positive and negative pressure output terminals. The positive and negative pressure generator typically only outputs fixed negative and positive pressures, which may be too high or too low, making it difficult to meet the lamp installation and removal requirements (for example, excessive negative pressure may damage the lamp, while insufficient negative pressure may cause the lamp to fall off during installation or removal due to insecure fixing). In this embodiment, by setting a pressure regulating device, the negative pressure (i.e., the negative pressure value inside the lamp slot 111) or positive pressure (i.e., the positive pressure value inside the lamp slot 111) output by the positive and negative pressure generator can be adjusted to a suitable range to fully meet the installation requirements. For example, the pressure regulating device may include a pressure gauge and a pressure regulating valve. The pressure regulating valve is used to adjust the pressure of the negative pressure or the positive pressure output from the positive and negative pressure output terminals. The pressure gauge is used to display the adjusted negative pressure (i.e., the negative pressure value within the lamp slot 111) or the positive pressure (i.e., the positive pressure value within the lamp slot 111). By using the pressure gauge and the pressure regulating valve, the pressure can be adjusted to a suitable value (e.g., a fixed parameter) each time the lamp is disassembled or installed, facilitating the standardization and normalization of disassembly and installation operations and avoiding disassembly / installation failures due to differences in operator technique or experience. In some embodiments, the pressure regulating device may only include a pressure regulating valve, which, by adjusting the opening of the valve to a suitable degree, adjusts the pressure value to a suitable range. For example, the connecting pipe may be a flexible hose, which effectively facilitates operator operation.

[0061] In some other embodiments, when the negative and positive pressures output from the positive and negative pressure output terminals of the positive and negative pressure generator can directly meet the requirements for lamp installation and removal, a pressure regulating device may not be provided in the pressure regulating assembly 200. That is, the pressure regulating assembly 200 may include a positive and negative pressure generator and a connecting pipe, and the positive and negative pressure output terminals of the positive and negative pressure generator are connected to the lamp slot 111.

[0062] In some embodiments, when the pressure adjustment assembly 200 is used only to generate negative pressure within the lamp slot 111 to fix the lamp 10 to the lamp slot 111, the pressure adjustment assembly may include a vacuum pump and a connecting pipe, with the vacuum pump connected to the lamp slot 111 via the connecting pipe. Exemplarily, a pressure regulating device as described above may also be provided between the vacuum pump and the lamp slot 111 to adjust the negative pressure output by the vacuum pump (i.e., the negative pressure value within the lamp slot 111) to a suitable range; this will not be elaborated further here.

[0063] Although exemplary embodiments have been described herein with reference to the accompanying drawings, it should be understood that the above exemplary embodiments are merely illustrative and are not intended to limit the scope of this application. Various changes and modifications can be made therein by those skilled in the art without departing from the scope and spirit of this application. All such changes and modifications are intended to be included within the scope of this application as claimed in the appended claims.

[0064] Numerous specific details are set forth in the specification provided herein. However, it will be understood that embodiments of this application may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0065] Similarly, it should be understood that, in order to streamline this application and aid in understanding one or more of the various aspects of the invention, features of this application may sometimes be grouped together in a single embodiment, figure, or description thereof in the description of exemplary embodiments of this application. However, this approach should not be construed as reflecting an intention that the claimed application requires more features than are expressly recited in each claim. Rather, as reflected in the corresponding claims, the inventive point lies in solving the corresponding technical problem with fewer features than all of those in a single disclosed embodiment. Therefore, the claims following the detailed description are hereby expressly incorporated into that detailed description, wherein each claim itself is a separate embodiment of this application.

[0066] Those skilled in the art will understand that, apart from the mutual exclusion of features, all features disclosed in this specification (including the accompanying claims, abstract, and drawings) and all processes or elements of any method or apparatus so disclosed can be combined in any combination. Unless otherwise expressly stated, each feature disclosed in this specification (including the accompanying claims, abstract, and drawings) may be replaced by an alternative feature serving the same, equivalent, or similar purpose.

[0067] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features but not others included in other embodiments, combinations of features from different embodiments are intended to be within the scope of this application and form different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0068] It should be noted that the above embodiments are illustrative of this application and not restrictive of this application, and that those skilled in the art can devise alternative embodiments without departing from the scope of the appended claims.
