Description

Technical Field

[0001] The invention relates to a clamp, in particular to an adhesive-backed clamp. Background Art

[0002] SMT (surface mount technology) is currently the most popular technology and process in the electronic assembly industry. In the process of making LED light strips, in order to improve work efficiency, the SMT technology is used to perform patch operations on the PCB board, which can effectively improve work efficiency. Specifically, the production process mainly includes tinning, correction, furnace passing and aging processes. After the chip is mounted on the PCB board, it is sent to the reflow furnace for passing through the furnace. It is necessary to ensure that the furnace temperature reaches the melting point of tin to ensure that the soldering position on the PCB board is stable. After the preparation of the light bar is completed, in order to facilitate the fixing of the light bar, it is necessary to perform a gluing operation on the light bar, that is, it is necessary to set an adhesive layer on the outer wall of the light bar, thereby installing the light bar to the product housing through the adhesive layer or facilitating the bonding of other lighting components to the surface of the light bar.

[0003] Since the surface of the light strip has electronic components such as LED lamp beads, resistors and terminals, these electronic components need to be avoided during the gluing process, that is, the gluing on the light strip is discontinuous, and there are many parts that need to be glued. In addition, the distribution positions of various components on light strips of different specifications are different, and their positioning positions are also different. It is difficult to perform batch gluing operations using fixtures, and the efficiency of manual gluing operations is slow and it is easy to miss glue. Especially in the case of mass production, the rate of defective products is high.

[0004] Therefore, how to solve the problem of product positioning during the gluing process with the existing fixture, avoid missing glue during the gluing process, and reduce the probability of product rework is a problem that technical personnel in this field need to solve.

[0028] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] See also Figure 1 and Figure 2 A back glue fixture 10 includes: a base 100, a positioning plate 200, a flap 300 and a positioning module 400. The fixture 100 is used for gluing on the surface of a light bar. The positioning plate 200 is arranged on the base 100, and the positioning module 400 is located between the base 100 and the positioning plate 200. The light bar to be glued is placed in the positioning plate 200, and the positioning module 400 positions the light bar to be glued to ensure that the light bar is set at the gluing position. The adhesive tape is placed on the flap 300, and the flap 300 is rotated to make the flap fit the positioning plate 200 so that the adhesive tape is attached to the surface of the light bar, so as to improve the gluing efficiency. The operator does not need to determine the sticking angle and position of each tape one by one, which reduces the phenomenon of glue failure and missing caused by human factors. By changing the relative position of each positioning column 420 on the positioning module 400 in the positioning plate 200, different types of light bars can be positioned, and the universality of the back glue fixture 10 is improved.

[0032] See also Figure 2 and Figure 4The positioning disk 200 includes a workbench 210, a hole mesh 220 and an origin limit bar 230. The workbench 210 is arranged on the base 100. A hollow cavity is opened at the center of the workbench 210, and the hollow cavity is the installation position on the workbench 210. The hole mesh 220 is embedded in the hollow cavity. The origin limit bar 230 is installed on the workbench 210, and the origin limit bar 230 is located at the edge of the hole mesh 220. The origin limit bar 230 is used to fit with the edge of the PCB board. The position of the origin limit bar 230 is the reference for positioning the positioning disk 200, that is, when placing the light bar, the outer wall of the light bar is fitted with the outer wall of the origin limit bar 230. After the positioning is completed in cooperation with the positioning module 400 and the light bar model is changed, the positioning module 400 adjusts the installation position with the position of the origin limit bar 230 as the origin to adapt to the positioning position on the light bar.

[0033] Furthermore, in order to improve the positioning effect of the origin limit bar 230, multiple origin limit bars 230 are provided. When placing the light bar, the side of the light bar is first made to fit with the outer wall of each limit bar 230, and the side of the light bar is preliminarily positioned by multiple origin limit bars 230. After the light bar is released, the positioning module 400 performs the next positioning operation to fix the light bar on the positioning plate 200.

[0034] It is understandable that since each operator has different operating habits, and personal operating habits will directly affect the efficiency of clamping the light strip, in order to cater to the usage habits of each operator, a plurality of spare installation positions are provided on the workbench 210, and the workbench 210 and the origin limit bar 230 are detachably connected. According to the operator's operating habits, the origin limit bar 230 can be adjusted to the corresponding installation position, and the origin limit bar 230 can be fixed to the surface of the workbench 210 by tightening screws or other connection methods. For example, the center lines of the plurality of origin limit bars 230 are on the same straight line, and the plurality of origin limit bars 230 are all located on the side of the hole network 220 away from the operator; for another example, the center lines of the plurality of origin limit bars 230 are on the same straight line, and the plurality of origin limit bars 230 are all located on the side of the hole network 220 close to the operator; for another example, the plurality of origin limit bars 230 are all located on the left side of the operator; for another example, the plurality of origin limit bars 230 are all located on the right side of the operator;

[0035] In one embodiment, in order to improve the auxiliary positioning effect of the origin limit bar 230, the origin limit bar 230 is set at the corner position of the hole mesh 220, and the origin limit bar 230 is provided with a first positioning edge 231 and a second positioning edge 232. When the light bar is pushed to fit with the outer wall of the origin limit bar 230, the first positioning edge 231 and the second positioning edge 232 are respectively fitted with the two adjacent sides of the light bar, thereby, the initial positioning operation of the light bar in the horizontal direction can be completed using a single origin limit bar 230. In order to prevent the edge of the light bar from getting stuck during the equal positioning process, a avoiding portion 233 is provided at the connecting position of the first positioning edge 231 and the second positioning edge 232. The avoiding portion 233 avoids the corners of the light bar, which can avoid the light bar from getting stuck, and can also prevent the outer wall of the origin limit bar 230 from being worn during the clamping process, thereby reducing the probability of defective products.

[0036] See also Figure 1 The flip cover 300 is hinged to the workbench 210, and a film pressing part 310 is provided on the side of the flip cover 300 close to the workbench 210. The flip cover 300 is rotated to drive the film pressing part 310 to fit with the mesh 220. The flip cover 300 is used to accommodate the tape. When performing the gluing operation, the tape is first laid on the film pressing part 310, and the release film of the tape is removed. When the flip cover 300 is rotated to drive the film pressing part 310 to fit with the mesh 220, the tape on the film pressing part 310 will contact and adhere to the outer wall of the light bar on the mesh 220, completing the gluing operation.

[0037] In order to improve the success rate of gluing, the material of the flip cover 300 is transparent acrylic. Thus, when performing the gluing operation, the matching state of the tape and the light strip can be directly observed through the cover 300 to determine whether the tape is completely attached to the light strip. Furthermore, in order to improve the efficiency of glue application, a plurality of guide grooves are provided on the film pressing portion 310. The operator lays the tape according to the instructions of the guide grooves. If there is any omission or the tape is placed incorrectly, it can be directly discovered through the flap 300. Since the flap 300 is made of a transparent material and the tape is made of a non-transparent material, that is, when there is a guide groove on which no tape is laid, the color displayed at the location of the guide groove is obviously different from the surrounding guide grooves on which tape has been laid, thereby prompting the operator that no tape has been added to the guide groove. The probability of missing glue is further reduced by providing the guide grooves, and the guide grooves can also assist the operator in laying the tape. When there is an error in the laying direction of the tape, the tape will extend beyond the guide groove. Due to the height difference between the inside and outside of the guide groove, the tape will have obvious folds at the edge of the guide groove, thereby prompting the operator that there is an error in laying the tape, thereby preventing incorrect or reverse application.

[0038] It should be noted that electronic components are distributed on the outer wall of the light bar, that is, the light bar has parts that need to be glued and parts that are not glued. In the actual production process, the operator is required to identify the parts that need to be glued and the parts that are not glued on the light bar, and attach the corresponding tape to its outer wall. As the light bar becomes larger, the number of components on it increases, and the number of places that need to be glued also increases. It is often the case that glue is applied to the wrong position, or the parts that need to be glued are not glued, resulting in the need for rework. By providing a film pressing portion 310 on the flap, the positions where the tape needs to be laid are indicated, and the operator does not need to identify them one by one, thereby reducing the probability of defective products. In addition, the gluing process does not require one-to-one alignment. It is only necessary to lay the tape on the film pressing portion 310 and flip the flap 300, thereby improving the gluing efficiency.

[0039] See also Figure 2 and Figure 3 The positioning module 400 includes an adsorption frame 410 and a plurality of positioning columns 420 . The adsorption frame 410 is installed on the base 100 , and the adsorption frame 410 is located directly below the workbench 210 . The plurality of positioning columns 420 penetrate the hole net 220 , and the adsorption frame 410 is used to adsorb the plurality of positioning columns 420 . That is, the adsorption frame 410 and the positioning posts 420 are separated. Specifically, the adsorption frame 410 is arranged in the base 100. When glue is needed, each positioning post 420 is inserted into the corresponding position of the hole mesh 220 according to the position of the positioning hole on the light strip. The adsorption frame 410 is magnetic. When the positioning posts 420 are inserted into the hole mesh 220, they will contact the adsorption frame 410. Each positioning post 420 is fixed on the hole mesh 220 through the magnetic field force generated by the adsorption frame 410 itself, thereby providing effective positioning for the light strip. When replacing the product, the positioning posts 420 can be directly pulled out from the hole mesh 220, and then each positioning post 420 can be inserted into the hole mesh 220 according to the positioning position on the new product. Through the cooperation between the hole mesh 220 and the adsorption frame 410, the installation position of the positioning posts 420 on the positioning plate 200 can be flexibly adjusted to adapt to products of different models and improve the application range of the adhesive clamp.

[0040] The working principle of the adhesive backing fixture 10 is introduced below:

[0041] Before the gluing operation is performed, a debugging operation needs to be performed, in which the positioning plate 200 is placed on the base 100 , and the flip cover 300 is rotated to move the flip cover 300 away from the positioning plate 200 .

[0042] Place the sample of the light bar that needs to be glued into the positioning plate 200, place the sample light bar on the outer wall of the mesh 220, and push the sample light bar so that the side of the sample light bar fits with the outer wall of the origin limit bar 230 on the workbench 210 to complete the initial positioning of the sample light bar;

[0043] Take out the positioning column 420, fit the outer wall of the positioning column 420 with the positioning part of the sample light bar, insert the positioning column 420 into the hole mesh 220 along the outer wall of the positioning part of the sample light bar, make the positioning column 420 contact with the adsorption frame 410 on the base 100, and fix the positioning column 420 by the magnetic field force generated by the adsorption frame 410.

[0044] Then proceed with the gluing operation;

[0045] Take out the sample light strip on the mesh 220;

[0046] The outer wall of the light strip to be glued is fitted with the outer wall of the origin limit strip 230, and the light strip is pressed toward the hole mesh 220 to make the light strip descend and fit with the hole mesh 220. At this time, the limit strip 230 is restricted by the origin limit strip 230 and the positioning column 420 so that it cannot translate in the horizontal direction.

[0047] Next, tape is laid on the film pressing portion 310 of the flip cover 300 , and the flip cover 300 is rotated to fit the hole mesh 220 , at which time the tape on the film pressing portion 310 contacts and adheres to the light bar on the hole mesh 220 .

[0048] Finally, open the flip cover 300 again, take out the light strip, put the next light strip to be glued back into the positioning plate 200, and repeat the above operation.

[0049] In one embodiment, please refer to Figure 2 In order to improve the structural stability of the base, the base 100 includes a carrier plate 110 and a plurality of supporting feet 120, and the plurality of supporting feet 120 are installed on the carrier plate 110 at intervals. A mounting cavity 111 is provided at the center of the carrier plate 110, and the adsorption frame 410 is accommodated in the mounting cavity 111. That is, a hollow structure is provided at the center of the carrier plate 110, and the adsorption frame 410 for fixing the positioning column 420 is accommodated in the mounting cavity 111, and the positioning plate 200 for carrying the light bar is provided on the outer wall of the carrier plate 110, so that the adsorption frame 410 is located directly below the hole net 220, saving installation space, and the mounting cavity 111 can provide a movable space for the adsorption frame 410. In the case where the positioning position of the adhesive product is greatly different, the position of the adsorption frame 410 in the mounting cavity 111 can be adjusted to cope with it, without making the adsorption frame 410 into the same area as the hole net 220, saving materials, and reducing the total mass of the adhesive clamp 10, which is convenient for storing and retrieving the clamp.

[0050] See also Figure 2 and Figure 3Specifically, the positioning post 420 is fixed by the magnetic field force provided by the adsorption frame 410, and the range of action of the magnetic field force is small, that is, the distance between the positioning post 420 and the adsorption frame 410 needs to be small enough to play a fixing role. When the distance between the positioning post 420 and the adsorption frame 410 exceeds the range of action of the magnetic field force, the positioning post 420 will become loose. In actual use, external impurities such as small particles and dust will pass through the hole mesh 220 and fall onto the surface of the adsorption frame 410, forming a barrier layer between the adsorption frame 410 and the positioning post 420. If it is not cleaned in time, the thickness of the barrier layer will accumulate, so that the distance between the positioning post 420 and the adsorption frame 410 is greater than the range of action of the magnetic field force of the adsorption frame 410, resulting in the positioning post 420. 420 cannot be effectively fixed. In order to avoid the above phenomenon, the adsorption frame 410 needs to be cleaned regularly. In order to facilitate the cleaning and maintenance of the adhesive clamp 10, the base 100 also includes a telescopic member 130. The telescopic member 130 is installed on the outer wall of the carrier plate 110. The output end of the telescopic member 130 passes through the installation cavity 111, and the output end of the telescopic member 130 is abutted against the outer wall of the adsorption frame 410. The telescopic member 130 is used to push the adsorption frame 410 to move back and forth in the direction close to or away from the installation cavity 111. When the adsorption frame 410 needs to be cleaned, the telescopic member 130 is started to push the adsorption frame 410 out of the installation cavity 111, which is convenient for the operator to clean it and also provides convenience for replacing the adsorption frame 410.

[0051] For further information, see Figure 3 When the cover 300 is opened, the flap 300 is turned in a direction away from the mesh 220 until it abuts against the back support 140. At this time, the flap 300 is just facing the operator. Specifically, at this time, the angle between the flap 300 and the mesh 220 is an obtuse angle. The degree of the obtuse angle can be changed by adjusting the installation position of the supported support 140. The farther the support support 140 is from the operator, the greater the degree of the angle between the flap 300 and the mesh 220. Conversely, the closer the support support 140 is to the operator, the smaller the degree of the angle between the flap 300 and the mesh 220 is. The adjustment is made according to the height of the operator to provide a comfortable working environment for the operator.

[0052] Furthermore, in order to save equipment manufacturing costs and increase the adsorption range of the adsorption frame 410, the telescopic member 130 includes a lifting cylinder 131 and a lateral translation cylinder 132. The lateral translation cylinder 132 is installed on the outer wall of the carrier plate 110, and the lifting cylinder 131 is installed on the output end of the lateral translation cylinder 132. The output end of the lifting cylinder 131 abuts against the adsorption frame 410. The lifting cylinder 131 is used to push the adsorption frame 410 to move back and forth in a direction close to or away from the installation cavity 111, so as to facilitate the cleaning of the adsorption frame 410. The lateral translation cylinder 132 is used to push the adsorption frame 410 to move back and forth in a direction close to or away from the installation cavity 111. 0 is laterally translated along the inner wall of the installation cavity 111, so that the volume of the adsorption frame 410 can be reduced, and the positioning requirements of products of different specifications can be met by pushing the attachment frame 410 to translate in the installation cavity 111 through the lateral translation cylinder 132. Specifically, when it is necessary to replace the light bar to be glued with other models, and the positioning position of the light bar is greatly different from the positioning position of the light bar of the previous model, the lateral translation cylinder 132 can be started to move the adsorption frame 410 to the bottom of the positioning position of the light bar, without making the adsorption frame 410 into the same size as the hole net 220, thereby saving the production cost of the adsorption frame 410.

[0053] The specific maintenance operations are as follows:

[0054] First, close the flip cover 300 and lift the positioning plate 200 off the base 100. At this time, the state of the base 100 is as follows: Figure 3 As shown, the opening of the mounting cavity 111 faces the operator;

[0055] At this time, the lifting cylinder 131 is started to lift the adsorption frame 410 so that the adsorption frame 410 is exposed outside the installation cavity 111. At this time, the operator does not need to remove the surrounding parts and can directly disassemble the adsorption frame 410, thereby reducing the loading and unloading steps of the adsorption frame 410. Moreover, since the adsorption frame 410 is exposed outside the installation cavity 111 at this time, the outer wall of the adsorption frame 410 can be directly wiped, and the cleaning process does not require disassembly, thereby reducing the difficulty of cleaning.

[0056] In one embodiment, in order to facilitate later maintenance, the adsorption frame 410 includes an outer frame 411 and a magnetic plate 412. The magnetic plate 412 is embedded in the outer frame 411, and the outer frame 411 is accommodated in the installation cavity 111. The outer frame 411 fits the inner wall of the installation cavity 111, and a wear-resistant layer is provided on the outer wall of the outer frame 411. The magnetic plate 412 is the main component for providing magnetic field force, that is, the magnetic plate 412 is a consumable item. After long-term use, the magnetic plate 412 will be damaged. When it cannot generate enough magnetic field force to fix the positioning column 420, the magnetic plate 412 can be replaced separately. The outer frame 411 is a supporting component, and a new magnetic plate 412 can be installed in the outer frame 411, which reduces the difficulty of maintenance.

[0057] For further information, see Figure 5In order to reduce the probability of external debris falling into the positioning plate 200, a plurality of through holes 221 are provided on the mesh 220, and each positioning column 420 is correspondingly provided with a through hole 221. An elastic seal is provided on the inner wall of each through hole 221. The elastic seal includes a plurality of resin springs 222, and the plurality of resin springs 222 abut against each other to seal the through hole 221. The thickness of the elastic seal is less than the thickness of the mesh 220. The plurality of resin springs 222 are distributed in a circular array with the axis of the through hole 221 as the center. When the positioning column 420 is inserted into the mesh 220, the resin springs 222 are bent by force. When the positioning column 420 is withdrawn, the resin springs 222 are reset under the action of their own elasticity and return to the initial state to seal the through hole 221 again.

[0058] For further information, see Figure 5 In order to facilitate the disassembly and assembly of the positioning column 420, the positioning plate 200 also includes a guide plate 240, which is embedded in the hollow cavity and located directly below the hole mesh 220. A plurality of guide holes 241 are opened on the guide plate 240, and the plurality of guide holes 241 are connected to the plurality of through holes 221 in a one-to-one correspondence.

[0059] Compared with the prior art, the present invention has at least the following advantages:

[0060] The above-mentioned adhesive backing clamp 10 is provided with a base 100, a positioning plate 200, a flap 300 and a positioning module 400. The positioning plate 200 is placed on the base 100, and the positioning plate 200 and the base 100 are separated, which is convenient for taking, placing and maintaining. The positioning module is arranged on the base 100, and positions the light bar in the positioning plate 200, and the installation position of the positioning module can be flexibly adjusted according to the locatable part of the light bar, so as to improve the universality of the adhesive clamp. The adhesive tape is accommodated on the flap 300, and the adhesive tape is attached to the outer wall of the light bar by rotating the flap 300. There is no need to manually adjust the adhesive position during the adhesive process, so as to reduce the phenomenon of wrong position and missing adhesive, and improve the accuracy of adhesive application.
