A type of mobile phone case hole printing release agent jig

Abstract

This utility model discloses a release agent printing fixture for mobile phone case holes, relating to the technical field of mobile phone case processing fixtures. It includes a base platform with a placement groove and a water-absorbing component for storing the release agent. It also includes a printing block corresponding to the edge of the hole. The water-absorbing component absorbs and stores liquid release agent. When the printing block is brought into contact with the water-absorbing component and a certain pressure is applied, the release agent inside the water-absorbing component is squeezed out, leaving the printing block coated with release agent. The printing block is then pressed onto the hole of the mobile phone case, printing the release agent onto the edge of the hole. The release agent is subsequently dried, forming an isolation layer near the hole of the mobile phone case, allowing the phone case to be transferred for secondary injection molding. After secondary injection molding, the non-stick properties of the release agent allow for quick cleaning of any overflowing adhesive, solving the problem of difficult-to-clean adhesive overflow at the hole after secondary injection molding and improving the product's aesthetics.

Description

Technical Field

[0001] This utility model relates to the field of mobile phone case processing fixtures, and in particular to a fixture for printing release agent on the holes of mobile phone cases. Background Technology

[0002] Since mobile phones are carried close to the body, they can easily slip from the hand if one is not careful or negligent. The fall often causes varying degrees of damage to the phone. Therefore, people usually wear phone cases to protect their phones.

[0003] As people's requirements for product appearance and quality increase, two-color / two-material injection molded phone cases are widely used because they combine aesthetics and functionality. These phone cases require two injection molding processes during production.

[0004] However, after the first injection molding is completed, the inside of the semi-finished phone case needs to be injection molded a second time. During the second injection molding process, it is unavoidable that glue overflow will occur in the holes of the semi-finished phone case (such as USB-C interface, speaker mesh, side key slot, etc.). The overflow is difficult to remove and seriously affects the appearance of the product.

[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content

[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixture for printing release agent in the holes of a mobile phone case, including a base platform, a placement groove provided on the base platform, and a water-absorbing component provided on the base platform for storing the release agent;

[0008] It also includes an ink block, which corresponds to the edge of the hole.

[0009] As a further embodiment of this utility model: a liquid storage tank is provided on the base platform, and the water-absorbing component is placed in the liquid storage tank.

[0010] As a further embodiment of the present invention: the liquid storage tank has a lower tank and an upper tank, and the lower tank and the upper tank form a stepped structure;

[0011] The absorbent component includes a seepage component and a wiping component, with the seepage component located in the lower tank and the wiping component located in the upper tank.

[0012] As a further embodiment of this utility model: a portion of the lower end face of the wiping component is in contact with the upper end face of the seepage component.

[0013] As a further embodiment of this utility model: the printing block includes an adhesive block and a fixing block, wherein the adhesive block is attached to the side of the fixing block.

[0014] As a further embodiment of this utility model: a mounting plate is connected to the fixing block.

[0015] As a further embodiment of this utility model: the base platform is also provided with clearance grooves located on both sides of the placement groove, one side of the clearance groove extends into the placement groove, and the bottom surface of the clearance groove is lower than the bottom surface of the placement groove.

[0016] Compared with the prior art, the beneficial effects of this technical solution are as follows: The absorbent component contains release agent liquid. When the printing block comes into contact with the absorbent component and a certain pressure is applied, the release agent inside the absorbent component is squeezed out. At this time, the printing block is covered with release agent. Then, the printing block is pressed onto the hole of the phone case. The printing block prints the release agent onto the edge of the hole. After the release agent is dried, an isolation layer is formed near the hole of the phone case. The phone case can then be transferred for secondary injection molding. After the secondary injection molding is completed, the non-stick properties of the release agent can be used to quickly clean up the overflowing glue, solving the problem of difficult cleaning of overflowing glue at the hole after secondary injection molding and improving the aesthetics of the product.

[0017] When applying release agent to the printing block, first press the printing block down into the liquid-draining part in the tank, thereby squeezing the release agent from the liquid-draining part. Then, the printing block is wiped away by the liquid-wiping part to remove excess release agent from its surface, such as water droplets formed by the release agent. This allows the surface of the printing block to be evenly covered with a layer of release agent, so that the release agent will not flow into the printing separation area during printing, thus improving the printing quality.

[0018] The lower end of the wiping component contacts the upper end of the seepage component, allowing the release agent obtained by the wiping component from the adhesive block to slowly flow downwards under its own gravity and enter the interior of the seepage component below. This increases the usage time of the seepage component after a single replenishment of release agent.

[0019] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-4 A release agent printing fixture for mobile phone case holes includes a base 1, a placement groove 11 on the base 1, and a water-absorbing element 2 on the base 1 for storing release agent.

[0029] It also includes an ink block 3, which corresponds to the edge of the hole.

[0030] Preferably, the absorbent component 2 contains release agent liquid. When the printing block 3 comes into contact with the absorbent component 2 and a certain pressure is applied, the release agent inside the absorbent component 2 is squeezed out. At this time, the printing block 3 is coated with release agent. Then, the printing block 3 is pressed onto the hole of the phone case, and the printing block 3 prints the release agent onto the edge of the hole. Subsequently, the release agent is dried, so that an isolation layer is formed near the hole of the phone case. The phone case can then be transferred for secondary injection molding. After the secondary injection molding is completed, the non-stick properties of the release agent can be used to quickly clean up the overflowing glue, solving the problem of difficult-to-clean glue overflow at the hole after secondary injection molding and improving the aesthetics of the product.

[0031] Based on the above embodiments, it is further proposed that a liquid storage tank 12 is provided on the base 1, and the water absorption component 2 is placed in the liquid storage tank 12.

[0032] Specifically, after the absorbent 2 is placed inside the liquid storage tank 12, release agent liquid is poured into the liquid storage tank 12. The absorbent 2 absorbs the release agent into the porous structure inside. When the printing block 3 contacts and is squeezed against the absorbent 2, the release agent inside the absorbent 2 will be squeezed out, thereby causing the surface of the printing block 3 to be covered with release agent.

[0033] Based on the above embodiments, it is further proposed that the printing block 3 includes an adhesive block 31 and a fixing block 32, wherein the adhesive block 31 is attached to the side of the fixing block 32.

[0034] Specifically, the adhesive block 31 is attached to the side of the fixing block 32 to facilitate the application of release agent to the adhesive block 31.

[0035] Furthermore, the liquid storage tank 12 has a lower tank 121 and an upper tank 122, with the lower tank 121 and the upper tank 122 forming a stepped structure;

[0036] The absorbent component 2 includes a seepage component 21 and a wiping component 22. The seepage component 21 is located in the lower tank 121, and the wiping component 22 is located in the upper tank 122. A portion of the lower end face of the wiping component 22 is in contact with the upper end face of the seepage component 21.

[0037] Specifically, when the printing block 3 is dipped in release agent, the printing block 31 is first pressed down into the liquid seepage part 21 in the groove 121, so that the release agent is dipped from the liquid seepage part 21 by squeezing. Then the printing block 31 is wiped away by the liquid wiping part 22 to remove the excess release agent on its surface, such as the water droplets formed by the release agent, so that the surface of the printing block 31 is evenly covered with a layer of release agent, so that the release agent will not flow into the printing area during printing, thus improving the printing quality.

[0038] The lower end face of the wiping component 22 contacts the upper end face of the seepage component 21, allowing the release agent obtained by the wiping component 22 from the adhesive block 31 to slowly flow downwards under its own gravity and enter the interior of the seepage component 21 below, which can increase the usage time of the seepage component 21 after a single replenishment of release agent.

[0039] Preferably, the absorbent 2 is a sponge. The micropores inside the sponge maintain the release agent in a stable saturated state through capillary effect, avoiding the droplet hanging or splashing caused by traditional dipping. In addition, the internal microporous structure can also limit the amount of release agent seepage, ensuring that the adhesive block 31 does not carry too much release agent.

[0040] Furthermore, a mounting plate 4 is connected to the fixing block 32.

[0041] Specifically, the fixing block 32 is connected to the mounting plate 4 by means of bolts, snap-fit, etc. The mounting plate 4 can be installed on the automatic dispensing machine. The dispensing machine controls the movement path of the mounting plate 4 and the printing block 3 through a pre-set program, thereby achieving the effect of automated dispensing, wiping and printing, so as to improve printing efficiency.

[0042] Preferably, in this embodiment, the method of setting the path of the dispensing machine to drive the mounting plate 4 and the printing block 3 is a mature existing technology in the field of automation, and will not be described in detail here.

[0043] Based on the above embodiments, it is further proposed that the base platform 1 is also provided with relief grooves 13 located on both sides of the placement groove 11. One side of the relief groove 13 extends into the placement groove 11, and the bottom surface of the relief groove 13 is lower than the bottom surface of the placement groove 11, so that when the mobile phone case is placed in the placement groove 11, a hollow is formed between it and the bottom surface of the relief groove 13, so as to facilitate the removal of the mobile phone case that needs to be printed with adhesive.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
