Description

Technical Field

[0001] The present invention relates to the technical field of LED lamp assembly, and in particular to an assembly workbench for combining upper and lower shells of an LED lamp. Background Art

[0002] LED lamps refer to devices that can transmit light, distribute and change the light distribution of LED light sources. In addition to the LED light source, they include all parts, components, upper and lower shells required to fix and protect the LED light source, as well as the circuit accessories necessary for connecting to the power supply. The upper and lower shells of LED lamps are the shells that protect the LED light source. After the LED light source is assembled, the upper and lower shells on the light source are assembled together.

[0003] At present, when the upper and lower shells of LED lamps are assembled together, the assembly workbench used is mostly fixed with a clamping structure. When the upper and lower shells of the LED lamps are clamped and fixed on the workbench, the shells are often broken due to the large clamping force of the clamping structure, resulting in waste of the upper and lower shells of the LED lamp. In addition, after the upper and lower shells are assembled, the clamping structure needs to be adjusted before the upper and lower shells can be taken out. When assembling the next set of upper and lower shells, the clamping structure needs to be adjusted repeatedly. The operation steps are cumbersome and affect the overall continuity of the assembly work. Summary of the Invention

[0011] As a preferred technical solution of the present invention, a buffer rubber pad is installed at the lower edge of the mold base groove of the lower mold base. The buffer rubber pad is an arc-shaped structure. The buffer rubber pad prevents the upper and lower shells from breaking due to lack of buffering force during assembly.

[0012] As a preferred technical solution of the present invention, buffer springs are installed on the inner wall of the lower end of the rectangular box at equal distances from left to right. The buffer springs are symmetrically arranged front to back, and a connecting plate is installed between the two buffer springs in the front and rear.

[0015] 2. The lower pressure plate in the present invention drives the assembled upper and lower shells to move upward, thereby removing the assembled shells from the lower mold base, making it easier to remove the upper and lower shells of the assembled LED lamp, and avoiding the problem of deformation of the side walls caused by a large external force when removing the upper and lower shells of the LED lamp.

DETAILED DESCRIPTION

[0029] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0030] See Figure 1 A workbench for assembling the upper and lower shells of LED lamps includes an assembly table 1, an L-shaped bracket 2, an upper fixing mechanism 3 and a lower fixing mechanism 4. The assembly table 1 consists of a rectangular box with an upward opening and two supporting legs. The two supporting legs are fixedly installed at the lower ends of the rectangular box. The lower fixing mechanism 4 is installed in the rectangular box. The rear end surface of the rectangular box is installed with the L-shaped bracket 2, and the front end surface of the L-shaped bracket 2 is installed with the upper fixing mechanism 3.

[0031] See Figure 1 、 Figure 3 、 Figure 4 、 Figure 8The lower end fixing mechanism 4 includes a rectangular tube 40, a supporting spring 41, a supporting tube 42, a lower mold base 43, a No. 1 wind gathering groove 44, a No. 1 air pump 45, a telescopic tube 46, a rectangular cavity plate 47, a rectangular card slot 48 and a No. 1 adsorption hole 49. A plurality of groups of rectangular tubes 40 are installed at equal distances from left to right in the rectangular box, and every five rectangular tubes 40 form a group. Each group of rectangular tubes 40 is arranged in a pentagonal shape. A supporting tube 42 is installed in the rectangular tube 40 through a supporting spring 41. A lower mold base 43 is installed between each group of supporting tubes 42. The lower mold base 43 and the supporting tube 42 are detachably connected. A No. 1 wind gathering groove 44 is provided on the rectangular box, and a No. 1 air pump is installed on the lower end surface of the rectangular box. Pump 45, the air intake of the No. 1 air pump 45 is connected to the No. 1 wind collecting groove 44 through a connecting pipe, and the inner wall of the lower end face of the rectangular box is equidistantly installed with a telescopic tube 46 connected to the No. 1 wind collecting groove 44 from left to right, and the upper end of the telescopic tube 46 is installed with a rectangular cavity plate 47, and the lower end face of the lower mold base 43 is provided with a rectangular card slot 48, and the model groove of the lower mold base 43 is provided with a plurality of No. 1 adsorption holes 49, and the rectangular cavity plate 47 and the rectangular card slot 48 are detachably connected, and the upper end face of the rectangular cavity plate 47 is provided with intake holes corresponding to the No. 1 adsorption holes 49, and the intake holes are connected to the inner cavity of the rectangular cavity plate 47, and the model groove of the lower mold base 43 is adsorbed with the lower shell 101.

[0032] See Figure 1 、 Figure 2 and Figure 8 The upper end fixing mechanism 3 includes a downward moving groove 30, an electric slider 31, an F-shaped plate 32, a lower pressure plate 33, a second air collecting groove 34, a second air pump 35, a mounting groove 36, an upper mold base 37 and a second adsorption hole 38. The front end surface of the L-shaped bracket 2 is provided with a downward moving groove 30, in which an electric slider 31 is installed, and the front end surface of the electric slider 31 is provided with a left-right symmetrically arranged F-shaped plate 32, and the lower end surfaces of the two F-shaped plates 32 are jointly provided with a lower pressure plate 33, and the lower pressure plate 33 is provided with a second air collecting groove 34. A No. 2 air pump 35 is installed on the upper end surface through the base. The air intake of the No. 2 air pump 35 is connected to the No. 2 wind gathering groove 34 through a connecting pipe. A plurality of mounting grooves 36 are arranged equidistantly from left to right on the lower end surface of the lower pressure plate 33. An upper mold base 37 is detachably installed in the mounting groove 36. The upper mold base 37 corresponds one-to-one to the lower mold base 43. A plurality of No. 2 adsorption holes 38 are provided in the model groove of the upper mold base 37. The No. 2 adsorption holes 38 pass through the lower pressure plate 33 and are connected to the No. 2 wind gathering groove 34. The upper shell 102 is adsorbed in the model groove of the upper mold base 37.

[0033] During operation, air pump No. 1 45 and air pump No. 2 35 are started at the same time, and air pump No. 1 45 and air pump No. 2 35 respectively suck out the air in wind collecting groove No. 1 44 and wind collecting groove No. 2 34 through the connecting pipes connected thereto, and then the lower shell 101 is first placed in the mold groove of the lower mold base 43, so that air pump No. 1 45 adsorbs the lower shell 101 in the mold groove of the lower mold base 43 through the wind collecting groove No. 1 44, telescopic tube 46, rectangular cavity plate 47, and adsorption hole No. 1 to prevent the lower shell 101 from being displaced during assembly, and the elastic force of the support spring 41 is sufficient to support the weight of the lower shell 101, so that after the lower shell 101 is adsorbed and fixed, the support spring 41 does not shrink. After the lower shell 101 is fixed, the upper shell 102 is placed in the mold groove of the upper mold base 37, so that air pump No. 2 35 adsorbs the lower shell 101 through the wind collecting groove No. 2 34 and adsorption hole No. 2 The upper shell 102 is adsorbed in the mold groove of the upper mold base 37, so that the upper shell 102 is adsorbed and fixed. After the upper shell 102 and the lower shell 101 are all fixed, the F-type plate 32 is driven downward by the electric slider 31, and the F-type plate 32 drives the upper shell 102 to move downward through the lower pressure plate 33 and the upper mold base 37. When the upper shell 102 contacts the lower shell 101, the upper shell 102 pushes the lower shell 101 to move downward. At this time, the support spring 41 contracts downward. When the support spring 41 contracts to a certain extent and no longer contracts, the lower shell 101 is stuck in the upper shell 102, thereby realizing the assembly function of the upper and lower shells. The contraction of the support spring 41 avoids the problem of the lower shell 101 breaking due to the large impact force when the upper shell 102 moves upward. At the same time, multiple upper and lower shells are assembled, which improves the efficiency of assembling the upper and lower shells of LED lamps.

[0034] See Figure 7 、 Figure 8 and Figure 11 The lower end surface of the inner wall of the rectangular box is provided with a plurality of air outlet slots 10 connected to the No. 1 air gathering slot 44 at equal distances from left to right. Every two air outlet slots 10 form a group. The two air outlet slots 10 of each group are respectively located on the left and right sides of the telescopic tube 46. A T-shaped plate 11 is slidably connected in the air outlet slot 10. The lower end surface of the T-shaped plate 11 and the left and right inner walls of the air outlet slot 10 are both installed with electromagnets 12. The electromagnets 12 installed on the T-shaped plate 11 have opposite magnetic properties to the electromagnets 12 installed on the air outlet slot 10. The outer side of the air outlet slot 10 is symmetrically provided with retractable slots. 13. The receiving and releasing groove 13 is opened on the lower end surface of the rectangular box. The receiving and releasing groove 13 is connected to the lower end surface of the horizontal section of the T-shaped plate 11 by pushing the spring rod 14. The lower end surface of the rectangular cavity plate 47 is installed with a frame plate 15 arranged symmetrically on the left and right. The lower end of the frame plate 15 and the upper end of the T-shaped plate 11 are both installed with an adsorption magnet 16. The adsorption magnet 16 installed on the upper end of the T-shaped plate 11 has opposite magnetic properties to the adsorption magnet 16 installed on the lower end of the frame plate 15. A pressure sensor is provided above the T-shaped plate 11, and the pressure sensor is installed on the lower end surface of the rectangular box through a bracket.

[0035] During operation, the electromagnet 12 is energized to suck the T-shaped plate 11 into the air outlet slot 10, so that the air outlet slot 10 is closed. When the upper shell 102 moves downward and the lower shell 101 moves downward, when the upper and lower shells are snap-fitted and assembled, the position of the frame plate 15 at the lower end of the rectangular cavity plate 47 is sufficient for the upper and lower adsorption magnets 16 to attract each other. The magnetic adsorption force of the adsorption magnet 16 is greater than the magnetic adsorption force of the electromagnet 12, so that the adsorption magnet 16 brings the T-shaped plate 11 out of the air outlet slot 10. After the T-shaped plate 11 moves out of the air outlet slot 10, it will contact the pressure sensor under the suction force of the two adsorption magnets 16, and the pressure sensor is subjected to pressure. After that, a signal is sent out to control the electromagnet 12 to cut off the power. After the air outlet slot 10 is opened, the No. 1 adsorption hole 49 no longer adsorbs the lower shell 101. After the upper and lower shells are assembled, the lower pressure plate 33 moves upward. Since the suction force generated by the No. 2 air pump 35 is not enough to drive the upper and lower shells to move upward, the upper mold base 37 is separated from the upper shell 102. When the upper mold base 37 moves to an appropriate height, the assembled upper and lower shells can be taken out from the lower mold base 43, making it more convenient to take out the upper and lower shells of the assembled LED lamp, avoiding the problem of deformation of the side walls of the upper and lower shells of the LED lamp caused by a large external force.

[0036] See Figure 10 A buffer rubber pad 430 is installed at the lower edge of the mold base groove of the lower mold base 43. The buffer rubber pad 430 is an arc-shaped structure. The buffer rubber pad 430 prevents the upper and lower shells from breaking due to lack of buffering force during assembly.

[0037] See Figure 8 and Figure 10 Buffer springs 17 are installed on the inner wall of the lower end of the rectangular box at equal distances from left to right. The buffer springs 17 are arranged symmetrically front to back. A connecting plate 18 is installed between the two buffer springs 17 in the front and rear. Every two connecting plates 18 form a group. The upper ends of each group of connecting plates 18 are tightly attached to the lower end of the lower mold base 43. The buffer springs 17 play a buffering role in the assembly of the upper and lower shells, and at the same time play a supporting role for the lower mold base 43 before assembly.

[0038] See Figure 9 A sealing rubber pad 370 is installed near the edge of the upper end surface of the upper mold base 37. The sealing rubber pad 370 is tightly attached to the upper end of the mounting groove 36. The sealing rubber pad 370 seals the upper mold base 37 and the mounting groove 36, so that the upper mold base 37 adsorbs the upper shell 102 more tightly.

[0039] See Figure 5 and Figure 10The four corners of the rectangular slot 48 are all provided with arc-shaped grooves 480 near the lower end. A rotating rod 481 is rotatably connected in the arc-shaped groove 480. The rotating rod 481 passes through the lower end of the lower die base 43 and is equipped with a symmetrically arranged rotating handle. A fan-shaped baffle 482 is fixed on the rotating rod 481. The fan-shaped baffle 482 is slidably connected with the arc-shaped groove 480. The fan-shaped baffle 482 is tightly attached to the lower end surface of the rectangular cavity plate 47. The side walls of the lower die base 43 are evenly equipped with L-shaped The base 483, the lower end of the L-shaped base 483 penetrates into the inner wall of the upper end of the support tube 42, and the inner wall of the upper end of the support tube 42 is installed with a support plate 484 through a telescopic rod 485 symmetrically arranged above and below. The support plate 484 is tightly attached to the L-shaped base 483, and the support plate 484 is rotated away from the end face of the L-shaped base 483 and is connected to a tightening rod 486. After the tightening rod 486 passes through the support tube 42, a rotating frame is installed, and the tightening rod 486 and the support tube 42 are connected by threaded fitting.

[0040] During operation, when assembling the upper and lower shells of LED lamps with different structures, the upper and lower mold bases can be disassembled and replaced with the corresponding mold bases for use. First, the tightening rod 486 is rotated through the rotating frame so that the tightening rod 486 drives the pressing plate 484 to no longer tighten against the L-shaped holder 483. Then, the L-shaped holder 483 on the lower mold base 43 is taken out from the support tube 42. Then, the lower mold base 43 is turned over and the turning handle at the lower end of the lower mold base 43 is turned so that the turning handle drives the fan-shaped baffle 482 to be retracted into the arc-shaped groove 480 through the turning rod 481, so that the fan-shaped baffle 482 no longer presses against the rectangular cavity plate 47. Then, the rectangular cavity plate 47 is taken out of the rectangular slot 48, and then the corresponding mold base is replaced, so that the installation efficiency of the mold base is improved, and at the same time, the assembly table 1 can assemble the upper and lower shells of LED lamps with various shapes and structures.

[0041] See Figure 9 The left and right end surfaces of the mounting groove 36 are both provided with clamping grooves 360, and the lower end surface of the lower pressure plate 33 is provided with a plurality of sliding grooves 361 connected to the clamping grooves 360. A shift plate 365 is installed in the sliding groove 361 through a thrust spring 364. The shift plate 365 is installed on the end surface close to the clamping groove 360 with a push plate 366 slidingly connected to the clamping groove 360. The left and right side walls of the upper mold base 37 are both provided with spring grooves, and a T-shaped clamping plate 362 is installed in the spring groove through an extrusion spring 363. The T-shaped clamping plate 362 is in sliding contact with the clamping groove 360.

[0042] During operation, when the upper die base 37 is disassembled, the shift plates 365 on the left and right sides of the upper die base 37 are pushed to move toward the upper die base 37. The shift plates 365 drive the push plates 366 to squeeze the T-shaped clamping plate 362, so that the T-shaped clamping plate 362 squeezes the extrusion spring 363 and enters the spring groove. When the T-shaped clamping plate 362 is received in the spring groove, the upper die base 37 has no clamping force, which makes it convenient to remove the upper die base 37 and make the replacement of the upper die base 37 more convenient.

[0043] See Figure 9 The lower end surface of the shift plate 365 is located above the lower end surface of the upper mold base 37, thereby avoiding the problem that the shift plate 365 affects the assembly of the upper and lower shells.

[0044] During the specific work, the first step is to respectively adsorb the lower shell 101 and the upper shell 102 into the upper mold base 37 and the lower mold base 43 through the No. 1 air pump 45 and the No. 2 air pump 35, and then clamp the upper shell 102 on the lower shell 101 through the electric slider 31, thereby realizing the assembly function of the upper and lower shells.

[0045] In the second step, when the upper shell 102 moves downward and the lower shell 101 moves downward, the adsorption magnet 16 brings the T-shaped plate 11 out of the air outlet slot 10. After the T-shaped plate 11 moves out of the air outlet slot 10, it will contact the pressure sensor. After the pressure sensor is under pressure, it sends a signal to the outside, thereby controlling the electromagnet 12 to cut off the power. After the air outlet slot 10 is opened, the No. 1 adsorption hole 49 no longer adsorbs the lower shell 101. After the upper and lower shells are assembled, the lower pressure plate 33 moves upward. Since the suction force generated by the No. 2 air pump 35 is not enough to drive the upper and lower shells to move upward, the upper mold base 37 is separated from the upper shell 102. When the upper mold base 37 moves to an appropriate height, the assembled upper and lower shells can be taken out from the lower mold base 43.

[0046] In the third step, when assembling the upper and lower shells of LED lamps with different structures, the upper mold base 37 and the lower mold base 43 can be disassembled and replaced with corresponding mold bases for use.

[0047] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
