Description

Technical Field

[0001] The utility model relates to the technical field of pressure sensor processing equipment, in particular to a glue coating tool for processing a pressure sensor. Background Art

[0002] The pressure sensor is a device used to measure pressure. It can convert pressure into electrical signal output. During the processing of the pressure sensor, it needs to be coated with glue through the glue coating tooling. According to the specific design and processing requirements of the pressure sensor, it is replaced to ensure the efficiency, accuracy and reliability of the coating process.

[0003] In the prior art, the gluing tooling for pressure sensor processing is often difficult to ensure the uniformity of gluing during the gluing process because the gluing device is in too close contact with the pressure sensor, and it is easy to scratch the surface of the pressure sensor. In addition, it is difficult to control the clamping force of the clamping block on the pressure sensor during the clamping process of the pressure sensor, which may cause damage due to excessive clamping force.

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides a gluing tool for processing a pressure sensor, which utilizes a supporting buffer mechanism to buffer the pressure caused by the glue applicator, thereby ensuring the uniformity of the glue coating and avoiding scratches on the surface of the pressure sensor. The pressure sensor can be tightly clamped by relying on the clamping assembly without causing excessive extrusion to it, thereby solving the problems raised in the above-mentioned background technology.

[0007] The bottom of the sliding sleeve passes through and extends to the inside of the base plate, and the inside of the sliding sleeve passes through and is connected with a limiting rod, the bottom end of the screw sleeve passes through and extends to the inside of the base plate, and the inside of the screw sleeve passes through and is connected with a first screw rod, and the upper surface of the base plate is provided with a first through groove at the position corresponding to the first through groove and the first screw rod, a support frame is fixed to the upper surface of the base plate, and a lifting plate is arranged inside the support frame.

[0008] Furthermore, the support buffer mechanism includes a guide slide bar fixed to the bottom layer inside the support block, and two guide slide bars are symmetrically sleeved on both sides of the outer layer of the guide slide bar. A first spring sleeved on the outer layer of the guide slide bar is fixed on one side of the guide slide bar, and a connecting rod is rotatably connected to the outer side of the guide slide bar, and the top ends of the two connecting rods are rotatably connected to the bottom of the placement plate.

[0009] Furthermore, two connecting blocks are symmetrically fixed on both sides of the placement plate, slots are opened on both sides of the upper surface of the support block at positions corresponding to the connecting blocks, touch blocks are fixed inside the slots, and a touch slot is opened at the bottom of the connecting block at the position corresponding to the touch block.

[0010] Furthermore, two fifth through slots are symmetrically opened on both sides of the interior of the placement plate, a fourth screw rod is rotatably connected inside the fifth through slot, and an outer layer of the fourth screw rod is sleeved with a clamping block that penetrates through and extends to the outside of the fifth through slot.

[0011] Furthermore, a second bevel gear is fixed to one side of the fourth screw rod, and the front ends of the two second bevel gears are jointly meshed with a first bevel gear rotatably connected to the inside of the placement plate.

[0014] Furthermore, a third through slot is provided inside the front end of the lifting plate, a third screw rod is rotatably connected inside the third through slot, one side of the third screw rod passes through and extends to the outside of the third through slot, a second motor is fixed thereto, and a moving block is sleeved on the outer layer of the third screw rod, a front end of the moving block passes through and extends to the outside of the lifting plate, a glue applicator is fixed thereto, and a fourth through slot is provided at the front end of the lifting plate at a position corresponding to the glue applicator.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0016] 1. A supporting buffer mechanism is provided in the utility model. When the pressure sensor is glued, the glue applicator is pressed down to fit with the pressure sensor. As the glue applicator is pressed down continuously, the placement plate is continuously lowered, thereby driving the two connecting rods to be pressed down. As the two connecting rods are pressed down, the guide slider is driven to move along the guide slider. During the movement of the guide slider, the guide slider is subject to the rebound force of the first spring, thereby forming a buffer. When the touch grooves of the connecting blocks on both sides of the placement plate are combined with the touch blocks, the first motor is turned off at this time, and the distance between the glue applicator and the pressure sensor is just in fit and not too close, thereby avoiding excessive wear during the gluing process.

[0017] 2. The utility model is provided with a clamping assembly, which drives the two fourth screws to rotate through the knob in cooperation with the first bevel gear and the second bevel gear, and the rotation of the fourth screw drives the clamping block to move, and the pressure sensor is clamped and fixed by the clamping block. At the same time, when the clamping is completed, the clamping block cannot move, which causes the fourth screw to be unable to rotate, that is, motion interference is formed between the first bevel gear and the second bevel gear. At this time, the knob is continuously rotated to drive the second tooth block to continue to rotate the knob. Because the first bevel gear cannot rotate, the second tooth block cooperates with the second spring to form repeated and continuous useless work, thereby maintaining a stable clamping of the pressure sensor and preventing it from being damaged due to excessive clamping force.

[0018] To summarize, when the glue applicator is continuously pressed down to the surface of the pressure sensor, the support buffer mechanism is used to prevent damage to the sensor caused by excessive pressure. At the same time, it prevents the glue applicator and the pressure sensor from being too close, which may lead to uneven glue coating and product damage. At the same time, when the pressure sensor is clamped with the clamping component, the surface of the pressure sensor will not be damaged due to excessive clamping pressure on both sides.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] This embodiment aims to address the problem that during the gluing process of the gluing tooling for processing the pressure sensor in the prior art, it is often difficult to ensure the uniformity of the gluing because the gluing device is in too close contact with the pressure sensor, and it is easy to cause scratches on the surface of the pressure sensor.

[0028] like Figure 1-3 As shown, a glue coating tool for processing a pressure sensor includes a bottom plate 1, a support block 24 is arranged on the upper surface of the bottom plate 1, a placement plate 22 is arranged inside the support block 24, a support buffer mechanism 5 is installed between the placement plate 22 and the support block 24, and the support buffer mechanism 5 includes a guide slide 26 fixed to the bottom layer inside the support block 24, two guide slide blocks 28 are symmetrically sleeved on both sides of the outer layer of the guide slide 26, and a first spring 25 sleeved on the outer layer of the guide slide 26 is fixed on one side of the guide slide 28. During the movement of the guide slide 28, the first spring 25 is applied to the reverse thrust of the first spring 25, thereby forming a certain buffer, and the outer side of the guide slide 28 is rotatably connected to a connecting rod 27, and the top ends of the two connecting rods 27 are rotatably connected to the bottom of the placement plate 22;

[0029] Two sliding sleeves 18 are symmetrically fixed on both sides of the bottom of the support block 24, and a screw sleeve 2 is fixed at the middle position of the bottom of the support block 24. Two connecting blocks 23 are symmetrically fixed on both sides of the placement plate 22. Notches are opened at the positions of the connecting blocks 23 on both sides of the upper surface of the support block 24, and touch blocks 17 are fixed inside the notches. A touch groove is opened at the position of the touch block 17 at the bottom of the connecting block 23. When the touch groove contacts the touch block 17, the first motor 13 is controlled to be turned off;

[0030] The bottom of the sliding sleeve 18 penetrates and extends to the inside of the bottom plate 1, and the inside of the sliding sleeve 18 penetrates and connects the limit rod 19, the bottom end of the screw sleeve 2 penetrates and extends to the inside of the bottom plate 1, and the inside of the screw sleeve 2 penetrates and connects the first screw rod 3, the upper surface of the bottom plate 1 is provided with a first through groove 4 at the position corresponding to the first through groove 4 and the first screw rod 3, the upper surface of the bottom plate 1 is fixed with a support frame 7, and the inside of the support frame 7 is provided with a lifting plate 12;

[0031] The two sides of the lifting plate 12 penetrate and extend to the inside of the two sides of the support frame 7, and the two sides of the lifting plate 12 are penetrated and connected with the second screw rods 9. The two sides of the support frame 7 are provided with second through grooves 8 at the positions corresponding to the second screw rods 9. The top of the second screw rod 9 is fixed with a synchronous wheel 21, and a synchronous belt 20 is rotatably connected between the two synchronous wheels 21. One of the synchronous wheels 21 penetrates and extends to the bottom of the support frame 7 where the first motor 13 is fixed. The first motor 13 is started to cooperate with the synchronous belt 20 and the synchronous wheel 21 to drive the two second screw rods 9 to rotate, and the lifting plate 12 is lifted and lowered by the rotation of the second screw rod 9.

[0032] A third through slot 10 is provided inside the front end of the lifting plate 12, and a third screw rod 15 is rotatably connected inside the third through slot 10. One side of the third screw rod 15 passes through and extends to the outside of the third through slot 10, where a second motor 14 is fixed. A moving block is sleeved on the outer layer of the third screw rod 15, and the front end of the moving block passes through and extends to the outside of the lifting plate 12, where a glue applicator 11 is fixed. A fourth through slot 16 is provided at the front end of the lifting plate 12 at a position corresponding to the glue applicator 11.

[0033] When the pressure sensor is glued, the first motor 13 is started to cooperate with the synchronous belt 20 and the synchronous wheel 21 to drive the two second screws 9 to rotate, and the lifting plate 12 is lifted and lowered by the rotation of the second screws 9. At the same time, the second motor 14 is started to drive the third screw 15 to rotate, and the glue applicator 11 is moved to a suitable position by the rotation of the third screw 15.

[0034] As the lifting plate 12 continues to rise and fall, the glue applicator 11 contacts the pressure sensor and applies continuous pressure to it. As the glue applicator 11 continues to descend, the placement plate 22 is driven to continue to descend. The placement plate 22 continues to descend and drives the connecting rod 27 to descend. As the connecting rod 27 moves, the bottom end of the connecting rod 27 drives the guide slider 28 to move along the guide slider 26. During the movement of the guide slider 28, it is subjected to the reverse thrust of the first spring 25, thereby forming a certain buffer. When the touch slot inside the connecting block 23 descends to the touch block 17, the first motor 13 is turned off at this time. At the same time, the contact surface between the glue applicator 11 and the pressure sensor is just right.

[0035] Embodiment 2:

[0036] This embodiment aims to solve the problem that in the process of clamping the pressure sensor by the glue coating tooling in the prior art, it is difficult to control the clamping force of the clamping block on the pressure sensor, which may cause damage due to excessive clamping force.

[0037] like Figure 4-5 As shown, the embodiment is a glue coating tool for processing a pressure sensor, and two fifth through grooves 33 are symmetrically opened on both sides of the inner side of the placement plate 22, and the inner side of the fifth through groove 33 is rotatably connected with a fourth screw rod 30, and the outer layer of the fourth screw rod 30 is sleeved with a clamping block 29 that penetrates and extends to the outer side of the fifth through groove 33, and a second bevel gear 34 is fixed to one side of the fourth screw rod 30, and the front ends of the two second bevel gears 34 are jointly meshed with a first bevel gear 31 that is rotatably connected to the inner side of the placement plate 22;

[0038] The front end of the first bevel gear 31 passes through and extends to the outside of the placement plate 22, where a knob 32 is fixed. A clamping assembly 6 is installed between the first bevel gear 31 and the knob 32. The clamping assembly 6 includes a plurality of first tooth blocks 35 equidistantly fixed inside the first bevel gear 31. Two second tooth blocks 38 are symmetrically fixed at the outer side of the knob 32 corresponding to the position of the first tooth block 35. One end of the second tooth block 38 passes through and extends to the inside of the knob 32 where a second spring 37 is fixed. A guide groove 36 is provided inside the knob 32 at the position corresponding to the second tooth block 38.

[0039] The pressure sensor is placed on the upper surface of the placement plate 22, and the knob 32 is rotated to drive the first bevel gear 31 to rotate. The rotation of the first bevel gear 31 drives the two second bevel gears 34 to rotate, and then drives the fourth screw rod 30. The rotation of the fourth screw rod 30 drives the clamping block 29 to move, so as to clamp the pressure sensor;

[0040] When the clamping block 29 completes clamping the pressure sensor, the clamping block 29 cannot move, and thus the fourth screw rod 30 cannot rotate. The fourth screw rod 30 cannot rotate, resulting in motion interference between the first bevel gear 31 and the second bevel gear 34. At this time, the knob 32 is continuously rotated. Since the first bevel gear 31 cannot rotate, the second tooth block 38 is squeezed by the first tooth block 35 and moves toward the inside of the guide groove 36, and cooperates with the second spring 37 to form a reset cycle effect, thereby avoiding damage to the pressure sensor caused by excessive clamping force.

[0041] Working process and principle of this utility model:

[0042] Step 1: When the pressure sensor is glued, the first motor 13 is started to cooperate with the synchronous belt 20 and the synchronous wheel 21 to drive the two second screws 9 to rotate, and the lifting plate 12 is lifted and lowered by the rotation of the second screws 9. At the same time, the second motor 14 is started to drive the third screw 15 to rotate, and the glue applicator 11 is moved to a suitable position by the rotation of the third screw 15.

[0043] As the lifting plate 12 continues to rise and fall, the glue applicator 11 contacts the pressure sensor and applies continuous pressure to it. As the glue applicator 11 continues to descend, the placement plate 22 is driven to continue to descend. The placement plate 22 continues to descend and drives the connecting rod 27 to descend. As the connecting rod 27 moves, the bottom end of the connecting rod 27 drives the guide slider 28 to move along the guide slider 26. During the movement of the guide slider 28, the reverse thrust of the first spring 25 is applied to form a certain buffer. When the touch slot inside the connecting block 23 descends to the touch block 17, the first motor 13 is turned off. At the same time, the contact surface between the glue applicator 11 and the pressure sensor is just right.

[0044] Step 2: Place the pressure sensor on the upper surface of the placement plate 22, rotate the knob 32 to drive the first bevel gear 31 to rotate, the first bevel gear 31 rotates to drive the two second bevel gears 34 to rotate, and then drive the fourth screw rod 30, and the fourth screw rod 30 rotates to drive the clamping block 29 to move, so as to clamp the pressure sensor;

[0045] When the clamping block 29 completes clamping the pressure sensor, the clamping block 29 cannot move, and thus the fourth screw rod 30 cannot rotate. The fourth screw rod 30 cannot rotate, resulting in motion interference between the first bevel gear 31 and the second bevel gear 34. At this time, the knob 32 is continuously rotated. Since the first bevel gear 31 cannot rotate, the second tooth block 38 is squeezed by the first tooth block 35 and moves toward the inside of the guide groove 36, and cooperates with the second spring 37 to form a reset cycle effect, thereby avoiding damage to the pressure sensor caused by excessive clamping force.

[0046] In summary, the support buffer mechanism 5 is used to prevent the glue applicator 11 from being too close to the pressure sensor, resulting in uneven glue liquid. At the same time, when the pressure sensor is clamped, the clamping component 6 will not be damaged due to excessive clamping force.

[0047] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
