[0023] The present patent can be further clearly understood through the following specific embodiments, but they do not limit the present patent.

[0024] Embodiment 1: An automatic replacement mechanism for a glue valve, comprising: a glue valve seat 10 and a three-axis drive mechanism respectively installed on a machine table. At least two accommodating grooves 101 for placing the glue valve 1 are formed on the glue valve seat 10. A substrate 2 is installed on the three-axis drive mechanism. A claw cylinder 3 is arranged on one side of the vertically arranged substrate 2 facing the glue valve seat 10. The base 4 of the claw cylinder 3 is installed on the substrate 2. The first moving part 51 and the second moving part 52 of the claw cylinder 3 are arranged at intervals in the horizontal direction and can approach or move away from each other in the horizontal direction.

[0025] In the normal glue dispensing state, the valve body connected to the glue supply cylinder is driven by the three-axis drive mechanism to move above the product to be glue dispensed. At the same time, the glue supply cylinder supplies glue to the valve body, and the valve body precisely dispenses glue quantitatively, so as to realize continuous glue dispensing operation on the product.

[0026] On one side of each of the first movable part 51 and the second movable part 52 facing away from the substrate 2, a clamping block 6 is installed. On the surface of the clamping block 6 facing away from the first movable part 51, a convex block 61 is provided. On one side of each glue valve 1 placed in the glue valve seat 10 close to the substrate 2, a support bar 7 is installed. On two side surfaces of the support bar 7, a clamping groove 71 is respectively formed. The bottom surface of the clamping groove 71 is a vertical surface, and the inner side wall of the clamping groove 71 close to the clamping block 6 is an inclined surface. On one side of each convex block 61 facing another convex block 61, a vertical clamping surface matching the vertical bottom surface of the clamping groove 71 and an inclined clamping surface matching the inclined inner side wall of the clamping groove 71 are provided. When the jaw cylinder 3 is in the clamping state, the inclined clamping surface of the convex block 61 is in pressing contact with the inclined inner side wall of the clamping groove 71 on the support bar 7, and the vertical clamping surface of the convex block 61 is in pressing contact with the vertical bottom surface of the clamping groove 71 on the support bar 7;

[0027] When the glue valve needs to be replaced after being used for a period of time, then the first movable part and the second movable part on the jaw cylinder move away from each other, driving the convex blocks on the two movable parts away from the clamping grooves on the support bar, so that the old glue cartridge is placed in the empty accommodation groove in the glue valve seat by the drive of the three-axis mechanism. Then, the glue valve to be replaced is loosened. In the above process, the first movable part and the second movable part can effectively avoid damaging the glue valve due to excessive instantaneous clamping force through the spring, and prolong the service life of the glue valve.

[0028] A positioning pin 81 is installed on the substrate 2 between the first movable part 51 and the second movable part 52 of the jaw cylinder 3. On the surface of the support bar 7 of each glue valve 1 facing the substrate 2, a positioning hole 82 is formed. The other end of the positioning pin 81 connected to the substrate 2 at one end can be inserted into the positioning hole 82;

[0029] Through the drive of the three-axis mechanism, the substrate installed with the jaw cylinder is moved to near a new glue valve installed in the accommodation groove on the glue valve seat and the positioning pin installed on the substrate is made to be at the same height as the positioning hole on the new glue valve. The substrate is driven by the three-axis mechanism to move towards the new glue valve until the positioning pin is inserted into the positioning hole. At this time, the positioning of the glue valve in one direction is realized. Through the cooperation between the positioning pin and the positioning hole, the calibration of the position of the glue valve can be further realized before the glue valve is clamped and loaded, so as to improve the position accuracy of the glue valve after the clamping is completed, and further ensure the dispensing accuracy.

[0030] At least one horizontally arranged spring 11 is connected between the two clamping blocks 6.

[0031] The number of glue valves 1 in the glue valve seat 10 is less than the number of accommodation grooves 101 formed on the glue valve seat 10.

[0032] The lower end of the vertically extending clamping block 6 is connected to the second moving part of the first moving part 51.

[0033] Between the upper end of the clamping block 6 and the substrate 2, there is a mating connection through at least one set of slide rails 91 and sliders 92.

[0034] Embodiment 2: An automatic replacement mechanism for a glue valve, comprising: a glue valve seat 10 and a three-axis drive mechanism respectively installed on a machine table.

On one side of the vertically arranged substrate 2 facing the glue valve seat 10, there is a jaw cylinder 3. The base 4 of the jaw cylinder 3 is installed on the substrate 2. The first moving part 51 and the second moving part 52 of the jaw cylinder 3 are arranged at intervals in the horizontal direction and can approach each other or move away from each other in the horizontal direction.

[0035] On each side of the first moving part 51 and the second moving part 52 facing away from the substrate 2, there is a clamping block 6 installed. On the surface of the clamping block 6 facing away from the second moving part 52, there is a convex block 61. On one side of each glue valve 1 placed in the glue valve seat 10 close to the substrate 2, there is a support bar 7 installed. On two side surfaces of the support bar 7, there are respectively provided a clamping groove 71. The bottom surface of the clamping groove 71 is a vertical surface, and the inner side wall of the clamping groove 71 close to the clamping block 6 is an inclined surface. On one side of each convex block 61 facing another convex block 61, there is a vertical clamping surface matching with the vertical bottom surface of the clamping groove 71 and an inclined clamping surface matching with the inclined inner side wall of the clamping groove 71. When the jaw cylinder 3 is in the clamping state, the inclined clamping surface of the convex block 61 is in pressing contact with the inclined inner side wall of the clamping groove 71 on the support bar 7, and the vertical clamping surface of the convex block 61 is in pressing contact with the vertical bottom surface of the clamping groove 71 on the support bar 7.

[0036] By driving two clamping blocks to approach each other until they are in pressing contact with the support plate on the glue valve, the clamping and installation of a new glue valve can be realized. At the same time, through the centering clamping of the two moving-towards clamping blocks, the positioning of the glue valve in another direction can be realized, the automatic replacement of the glue valve can be automatically realized, manpower and operation time can be saved, the production efficiency can be improved, and the consistency of the position of the glue valve after replacement can also be ensured.

[0044] The working principle of the present utility model is as follows:

[0045] Under the normal glue dispensing state, the valve body connected with the glue supply cylinder is driven by the three-axis drive mechanism to move above the product to be glue dispensed. At the same time, the glue supply cylinder supplies glue to the valve body, and the valve body precisely dispenses glue quantitatively, realizing continuous glue dispensing operation on the product;

[0046] When the glue valve needs to be replaced after being used for a period of time, the first movable part and the second movable part on the clamping jaw cylinder move away from each other, driving the bumps on the two movable parts away from the clamping grooves on the support bar. Thus, the old glue cartridge is placed in the empty accommodating groove on the glue valve seat by the drive of the three-axis mechanism. Then, the glue valve to be replaced is loosened. During the above process, the first movable part and the second movable part can effectively avoid damaging the glue valve due to excessive instantaneous clamping force through the spring, extending the service life of the glue valve;

[0047] Then, through the drive of the three-axis mechanism, the substrate equipped with the clamping jaw cylinder is moved to near a new glue valve installed in the accommodating groove on the glue valve seat and the positioning pin installed on the substrate is made to be at the same height as the positioning hole on the new glue valve. The substrate is driven by the three-axis mechanism to move towards the new glue valve until the positioning pin is inserted into the positioning hole. At this time, the positioning of the glue valve in one direction is achieved. Through the cooperation between the positioning pin and the positioning hole, the calibration of the position of the glue valve can be further realized before the glue valve is clamped and loaded, thus the position accuracy of the glue valve after the clamping is completed, and further ensuring the accuracy of dispensing;

[0048] Then, the clamping jaw cylinder drives the two clamping blocks to move towards each other until they are in pressing contact with the support plate on the glue valve, thus realizing the clamping and installation of the new glue valve. At the same time, through the centering clamping of the two clamping blocks moving towards each other, the positioning of the glue valve in another direction is achieved, which can automatically realize the automatic replacement of the glue valve, saving manpower and operation time, improving production efficiency, and also ensuring the consistency of the position of the glue valve after replacement.

[0049] When the above automatic replacement mechanism for the glue valve is adopted, it can automatically realize the automatic replacement of the glue valve, saving manpower and operation time, improving production efficiency, and also ensuring the consistency of the position of the glue valve after replacement. Furthermore, it can ensure the accuracy of dispensing through the glue valve subsequently. Also, through the cooperation between the positioning pin and the positioning hole, the calibration of the position of the glue valve can be further realized before the glue valve is clamped and loaded, thus the position accuracy of the glue valve after the clamping is completed, and further ensuring the accuracy of dispensing; Moreover, at least one horizontally arranged spring is connected between the two clamping blocks, which can effectively avoid damaging the glue valve due to excessive instantaneous clamping force, extending the service life of the glue valve.
