A production line and its positioning device

Abstract

This utility model discloses an assembly line and its positioning device. The positioning device is used to position a first fixture on the assembly line and includes: a blocking mechanism, a lifting mechanism, and a side-push clamping mechanism. The blocking mechanism blocks the first fixture on the assembly line conveyor at a first station, so that the first fixture is above the lifting assembly of the assembly line. The lifting mechanism lifts the first fixture at the first station to a second station, so that the first fixture is detached from the conveyor. The side-push clamping mechanism pushes the first fixture at the second station to a third station and clamps the first fixture, so that the rod of the first fixture is located in the middle position of the conveyor and fixed. In other words, by using the blocking mechanism, the lifting mechanism, and the side-push clamping mechanism in sequence, this positioning device can position and fix the rod of the first fixture in the middle position of the assembly line conveyor, thereby facilitating the lifting assembly of the assembly line to lift and remove the second fixture.

Description

Technical Field

[0001] This utility model relates to the field of assembly line technology, and in particular to an assembly line and its positioning device. Background Technology

[0002] Currently, in order to perform specific actions on fixtures on an assembly line (such as removing other fixtures from a fixture), a positioning device is needed to position the fixture at a specific location on the assembly line so that specific actions can be performed on the fixture subsequently. For example, the assembly line's synchronous belt conveys the first fixture. First, the positioning device blocks the first fixture's forward movement and positions the first fixture in the flow direction. Then, the positioning device positions the first fixture on the side. Next, the positioning device presses the first fixture tightly. Subsequently, the assembly line's lifting component lifts the second fixture in the first fixture (the second fixture is mounted in the first fixture via a connecting rod). After the second fixture is removed, the positioning device releases the first fixture and removes the obstruction, allowing the first fixture to be conveyed to the next station on the assembly line.

[0003] In this process, when the first fixture is conveyed on the assembly line, its connecting rod is located in the middle of the two synchronous belts, which facilitates the lifting assembly to remove the second fixture from the first fixture. However, the lifting assembly of the existing assembly line cannot adapt to changes in the position of the connecting rod of the first fixture. When the connecting rod of the first fixture is offset (e.g., offset to the right, as...), Figure 4 As shown), the lifting assembly cannot lift the second fixture, causing the second fixture in the first fixture to be unable to be removed.

[0065] 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.

[0066] The positioning device provided in this embodiment of the utility model, such as Figure 1 As shown, the first fixture 2 used for positioning on the assembly line 1, such as Figure 2 As shown, the positioning device includes: a blocking mechanism 4, a lifting mechanism, and a side-pushing and pressing mechanism;

[0067] The blocking mechanism 4 is used to block the first fixture 2 on the conveyor mechanism of the production line 1 at the first station, so that the first fixture 2 is located above the lifting assembly 11 of the production line 1 (e.g., Figure 1 (as shown)

[0068] The lifting mechanism is used to lift the first fixture 2 located at the first station to the second station, so that the first fixture 2 is removed from the conveying mechanism;

[0069] The side-push clamping mechanism is used to push the first fixture 2 located at the second station to the third station and clamp the first fixture 2, so that the connecting rod 21 of the first fixture 2 is located in the middle position of the conveying mechanism and fixed.

[0070] It should be noted that, as Figure 2 As shown, the conveying mechanism of production line 1 can be a double synchronous belt conveyor mechanism; the first fixture 2 can be placed on the double synchronous belt conveyor mechanism and conveyed along with it; wherein, as Figure 4 As shown, the second fixture 3 is installed on the connecting rod 21 of the first fixture 2; of course, there are multiple second fixtures 3, and multiple second fixtures 3 are installed one by one on multiple connecting rods 21 of the first fixture 2.

[0071] like Figure 2 As shown, the blocking mechanism 4 can be installed on the machine base 12 of the production line 1 and is located in front of the lifting assembly 11 of the production line 1. The blocking mechanism 4 is used to block the first fixture 2 on the conveying mechanism of the production line 1 at the first station so that the first fixture 2 is located above the lifting assembly 11 of the production line 1.

[0072] like Figure 2As shown, the lifting mechanism can be installed on the machine 12 of the production line 1, and can be located on the left and right sides or the front and rear sides of the lifting assembly 11 respectively. The lifting mechanism is used to lift the first fixture 2 located at the first station to the second station so that the first fixture 2 is separated from the conveying mechanism. In this way, when the first fixture 2 is pushed to the third station laterally, interference between the first fixture 2 and the conveying mechanism of the production line 1 can be avoided, and the stability of the side-push positioning of the first fixture 2 can be improved.

[0073] The side-push clamping mechanism can be installed on the machine base 12 of the production line 1, and can be located on the left and right sides of the lifting assembly 11 respectively. The side-push clamping mechanism is used to push the first fixture 2 located at the second station to the third station and clamp the first fixture 2, so that the connecting rod 21 of the first fixture 2 is located in the middle position of the conveying mechanism and fixed. In this way, the connecting rod 21 of the first fixture 2, which was originally off-center, is positioned in the middle position of the conveying mechanism and fixed, so that the lifting assembly 11 of the production line 1 can lift and remove the second fixture 3 on the connecting rod 21. This solves the problem that the existing lifting assembly of the production line cannot lift and remove the second fixture 3 when the connecting rod 21 of the first fixture 2 is off-center.

[0074] Of course, after the lifting assembly 11 of the production line lifts and removes the second fixture 3, the side-push clamping mechanism can also release the first fixture 2 and push the first fixture 2 from the third station back to the second station. Then, the lifting mechanism can also lower the first fixture 2 from the second station back to the first station. Subsequently, the blocking mechanism 4 can also release the first fixture 2 located at the first station, so that the first fixture 2 can be transported to the next station by the conveying mechanism of the production line 1. That is, the blocking mechanism 4, the lifting mechanism and the side-push clamping mechanism all have the function of resetting the first fixture 2 to the corresponding station.

[0075] In response to the situation where the connecting rod of the first fixture is misaligned and the lifting assembly 11 of the production line 1 cannot lift and remove the second fixture 3, this solution improves the positioning device for positioning the first fixture 2 on the production line 1. This improves the positioning device to have blocking, lifting, and side-pushing / pressing functions, thus avoiding the need to modify the production line 1, which is relatively complex and difficult to implement. Specifically, the first fixture 2 on the conveying mechanism of the production line 1 is first blocked above the blocking mechanism 4 (i.e., the first station) by the blocking mechanism 4. Then, the lifting mechanism lifts the first fixture 2 to the conveying mechanism detached from the production line 1 (i.e., the second station), thus placing the first fixture 2 on the conveying mechanism of the production line 1. Above, when the first fixture 2 is pushed from the second station to the third station, the side-pushing friction between the first fixture 2 and the conveying mechanism can be avoided, thus avoiding interference between the first fixture 2 and the dual synchronous belt conveying mechanism of the production line 1 during the side-pushing, improving the reliability of this positioning device. Then, the side-pushing and pressing mechanism pushes the first fixture 2 located at the second station to the third station and presses the first fixture 2, so that the connecting rod 21 of the first fixture 2 is located in the middle position of the conveying mechanism and fixed, thus achieving the positioning and fixing of the first fixture 2. This corrects the position of the connecting rod 21 of the first fixture 2 to the middle position of the conveying mechanism and fixes it, so that the lifting assembly 11 of the production line 1 can lift and remove the second fixture 3.

[0076] Of course, this solution provides a special positioning method for the fixture on the synchronous belt of the production line, which can realize the correct positioning of the fixture without considering the relationship between the fixture structure and the synchronous belt structure of the production line. This positioning method can be applied to automated production lines with similar needs (such as electronic consumer product manufacturing production lines).

[0077] In other words, the positioning device provided in this solution is applicable to situations where the position of the connecting rod 21 of the first fixture 2 is offset; when the position of the connecting rod 21 of the first fixture 2 is offset (such as... Figure 4 As shown, by using the blocking mechanism, lifting mechanism and side-pushing clamping mechanism in sequence, the connecting rod 21 of the first fixture 2 is positioned and fixed in the middle position of the conveying mechanism of the assembly line. This makes the offset connecting rod 21 centrally positioned between the conveying mechanisms of the assembly line, which facilitates the lifting assembly of the assembly line to lift and remove the second fixture 3. Of course, the lifting assembly of the assembly line can only lift and remove the second fixture 3 when the offset connecting rod 21 is pushed to the center position of the conveying mechanism of the assembly line.

[0078] In this plan, such as Figure 2 As shown, the lifting mechanism includes: a first lifting mechanism 5 and a second lifting mechanism 6;

[0079] The first lifting mechanism 5 is located on the front side of the lifting assembly 11;

[0080] The second lifting mechanism 6 is located at the rear of the lifting assembly 11. The first lifting mechanism 5 and the second lifting mechanism 6 are used to simultaneously lift the front end and rear end of the first fixture 2 located at the first work station to the second work station.

[0081] As described above, the lifting mechanisms can be respectively installed on the front and rear sides of the lifting assembly 11 of the production line 1; more specifically, the first lifting mechanism 5 can be installed on the machine base 12 of the production line 1, and is located on the front side of the lifting assembly 11, and the first lifting mechanism 5 is also equivalent to the front lifting mechanism; Figure 3 As shown, the second lifting mechanism 6 can be installed on the machine base 12 of the production line 1 and is located behind the lifting assembly 11. The second lifting mechanism 6 is also equivalent to the rear lifting mechanism. That is to say, the lifting mechanism of this positioning device includes a front lifting mechanism and a rear lifting mechanism. The front and rear lifting mechanisms simultaneously lift the front and rear ends of the bottom of the first fixture 2 located at the first station to the second station. This allows the first fixture 2 to be lifted smoothly to the second station, ensuring the reliability of the lifting action of this positioning device. Of course, when the first fixture 2 is located at the second station, it is actually located on the first lifting mechanism 5 and the second lifting mechanism 6 respectively.

[0082] Specifically, such as Figure 6 As shown, the first lifting mechanism 5 includes: a support plate 51, a lifting block 52, a first lifting cylinder 53, and an adjustment assembly 54;

[0083] The support plate 51 is used to be vertically installed on the machine base 12 of the production line 1 and is located in front of the lifting assembly 11;

[0084] The first lifting cylinder 53 is located on the rear side of the support plate 51;

[0085] The lifting block 52 is set at the movable end of the first lifting cylinder 53 via the adjusting component 54. The first lifting cylinder 53 is used to drive the lifting block 52 to lift the front end of the first fixture 2 located at the first work station to the second work station. The adjusting component 54 can adjust the height of the lifting block 52.

[0086] It should be noted that, as Figure 5 or Figure 6 As shown, the support plate 51 can be vertically arranged on the machine base 12 of the production line 1, and is located in front of the lifting assembly 11. The support plate 51 is also equivalent to a vertical support plate; as Figure 6As shown, the first lifting cylinder 53 can be vertically arranged at the lower or lower-middle part of the rear plate of the support plate 51, and its movable end is vertically upward; the lower end of the adjusting component 54 is arranged at the movable end of the first lifting cylinder 53, and the lifting block 52 is arranged at the upper end of the adjusting component 54. The movable end of the first lifting cylinder 53 is used to drive the lifting block 52 to lift the front end of the bottom of the first fixture 2 located at the first workstation to the second workstation. The adjusting component 54 is used to adjust the height of the lifting block 52, that is, to adjust the lifting height of the first lifting mechanism; wherein, as Figure 6 As shown, the adjusting component 54 includes two adjusting blocks, and the first lifting mechanism 5 also includes a connecting seat 55. The lower end of the connecting seat 55 is located at the movable end of the first lifting cylinder 53. Two vertical sliding grooves are provided at the rear of the connecting seat 55, and these grooves extend through the top and bottom of the connecting seat 55. Two vertical mounting grooves are provided at the rear of the lifting block 52, and these grooves extend through the bottom of the lifting block 52. The upper ends of the two adjusting blocks are fixedly mounted to the two mounting grooves at the rear of the lifting block 52, and the lower ends are slidably mounted to the two sliding grooves at the rear of the connecting seat 55. The lower ends of the two adjusting blocks can simultaneously slide to different upper and lower positions of the two sliding grooves of the connecting seat 55, and the lower ends of the two adjusting blocks can be locked one by one by two locking parts (such as locking bolts), thereby realizing the adjustment of the height of the lifting block 52. Of course, the first lifting mechanism 5 is designed in this way, resulting in a simple structure, convenient lifting, and adjustable lifting height.

[0087] Furthermore, such as Figure 5 As shown, the blocking mechanism 4 includes: a blocking cylinder 41 and a blocking block 42;

[0088] The blocking cylinder 41 is located on the front side of the support plate 51;

[0089] The blocking block 42 is located at the movable end of the blocking cylinder 41. The blocking cylinder 41 is used to drive the blocking block 42 to block the first fixture 2 on the conveying mechanism at the first work station.

[0090] It should be noted that, as Figure 5 As shown, the blocking mechanism 4 also includes a mounting base 43; wherein, the blocking cylinder 41 can be vertically arranged on the lower part of the front plate surface of the support plate 51, and its movable end is vertically upward; the mounting base 43 can be arranged on the upper part of the front plate surface of the support plate 51, and has a U-shaped structure; the blocking block 42 can slide up and down along the cavity formed by the mounting base 43 and the front plate surface of the support plate 51, and its bottom is arranged on the movable end of the blocking cylinder 41. The movable end of the blocking cylinder 41 is used to drive the blocking block 42 to block the first fixture 2 on the conveying mechanism at the first work position, and the mounting base 43 can guide the up and down sliding of the blocking block 42; of course, the blocking mechanism 4 is designed in this way, which makes the structure simple and convenient for blocking, and the blocking mechanism 4 is integrated in the front part of the first lifting mechanism 5, which makes the structure of the blocking mechanism 4 and the first lifting mechanism 5 compact.

[0091] Furthermore, such as Figure 7 and Figure 8 As shown, the second lifting mechanism 6 includes: a lifting support, a second lifting cylinder 61, and a lifting plate 62;

[0092] The second lifting cylinder 61 is mounted on the machine base 12 of the production line 1 via a lifting support and is located on the rear side of the lifting assembly 11.

[0093] The lifting plate 62 is located at the movable end of the second lifting cylinder 61. The second lifting cylinder 61 is used to drive the lifting plate 62 to lift the rear end of the first fixture 2 located at the first station to the second station.

[0094] It should be noted that, as Figure 7 As shown, the lifting support includes: a mounting plate 63, a support base 64, and a support pad; the support pad can be mounted on the machine base 12 of the production line 1 and can be located on the rear side of the lifting assembly 11; the support base 64 is mounted on the support pad; the mounting plate 63 can be mounted at the front end of the top of the support base 64; the second lifting cylinder 61 can be vertically mounted on the front surface of the mounting plate 63, and its movable end is vertically upward; the bottom of the lifting plate 62 is located at the movable end of the second lifting cylinder 61, and the second lifting cylinder 61... The movable end is used to drive the lifting plate 62 to lift the rear end of the bottom of the first fixture 2 located at the first station to the second station; in addition, the front-to-back length of the lifting plate 62 is greater than its left-to-right width, making the lifting plate 62 a horizontal long plate along the front-to-back direction. In this way, when the first fixture 2 is transferred from the vertical direction to the production line 1, the rear part of the lifting plate 62 can be used to support the bottom of the first fixture 2, so that the first fixture 2 can be smoothly transferred to the production line 1; of course, the second lifting mechanism 6 is designed in this way, which makes the structure simple and the lifting convenient.

[0095] In this plan, such as Figure 2 As shown, the side-push clamping mechanism includes: a first side-push mechanism 7, a second side-push mechanism 8, and a clamping mechanism 9;

[0096] The first side-pushing mechanism 7 is disposed on the first side of the production line 1 and is used to push the first fixture 2 located at the second station to the third station.

[0097] The clamping mechanism 9 is disposed on the first and second sides of the production line 1 and is used to clamp the first fixture 2 located at the third station.

[0098] The second side-pushing mechanism 8 is located on the second side of the production line 1 and is used to push the first fixture 2, which is located in the third station, to the second station after the clamping mechanism releases the first fixture 2.

[0099] It should be noted that, as Figure 2As shown, the first side pushing mechanism 7 can be set on the machine base 12 of the production line 1 and can be located on the right side of the production line 1, that is, the first side of the production line 1 can be the right side. The first side pushing mechanism 7 can be used to push the first fixture 2 located at the second station to the left to the third station.

[0100] The clamping mechanism 9 may include: a first-side clamping mechanism and a second-side clamping mechanism; wherein, the first-side clamping mechanism may be disposed on the first-side pushing mechanism 7 and may be located on the right side of the assembly line 1, and the second-side clamping mechanism may be disposed on the second-side pushing mechanism 8 and may be located on the left side of the assembly line 1, that is, the second side of the assembly line 1 may be the left side, and the first-side clamping mechanism and the second-side clamping mechanism are used to clamp the first fixture 2 located at the third station towards each other; of course, the first-side clamping mechanism and the second-side clamping mechanism can also release the first fixture 2;

[0101] The second side-pushing mechanism 8 can be installed on the machine tool 12 of the production line 1 and can be located on the left side of the production line 1. The second side-pushing mechanism 8 can be used to push the first fixture 2 located at the third station to the right to the second station after the above-mentioned clamping mechanism releases the first fixture 2, so that the first fixture 2 is reset to the second station. Of course, the side-pushing clamping mechanism is designed in this way, which not only allows the first fixture 2 to switch between the second station and the third station, but also makes it easy to fix the first fixture 2 located at the third station stably, and also has the characteristics of distinct structural layers.

[0102] Specifically, such as Figure 9 As shown, the first side push mechanism 7 includes: a first side push support 71, a first side push cylinder 72, and a side push rod 73;

[0103] The first side push cylinder 72 is mounted on the machine base 12 of the production line 1 via the first side push support 71 and is located on the first side of the production line 1.

[0104] The side push rod 73 is located at the movable end of the first side push cylinder 72. The first side push cylinder 72 is used to drive the side push rod 73 to push the first fixture 2 located at the second station to the third station.

[0105] It should be noted that, as Figure 9As shown, the first side-pushing mechanism 7 also includes a side-pushing connecting plate 74; wherein, the first side-pushing support 71 can be set on the machine base 12 of the production line 1 and can be located on the right side of the production line 1; the first side-pushing cylinder 72 can be set horizontally at the top of the first side-pushing support 71, and its movable end is horizontally distributed to the left; the side-pushing connecting plate 74 is vertically set at the movable end of the first side-pushing cylinder 72; two side-pushing rods 73 are respectively set at the front end and rear end of the left plate surface of the side-pushing connecting plate 74; the movable end of the first side-pushing cylinder 72 can be used to simultaneously drive the two side-pushing rods 73 to push the first fixture 2 located at the second station to the left to the third station; the two side-pushing rods 73 can be used to push the right edge of the bottom of the first fixture 2 to the left, and are distributed at intervals along the front and rear direction of the production line 1, so as to facilitate the smooth side-pushing of the first fixture 2 located at the second station to the left to the third station; of course, the first side-pushing mechanism 7 is designed in this way, with a simple structure and convenient side-pushing.

[0106] Furthermore, such as Figure 11 As shown, the second side push mechanism 8 includes: a second side push support 81, a second side push cylinder 82, and a side push block 83;

[0107] like Figure 2 As shown, the second side push cylinder 82 is mounted on the machine base 12 via the second side push support 81;

[0108] The side push block 83 is located at the movable end of the second side push cylinder 82 and is located on the second side of the production line 1. The second side push cylinder 82 is used to drive the side push block 83 to push the first fixture 2 located at the third station to the second station after the clamping mechanism 9 releases the first fixture 2.

[0109] It should be noted that, as Figure 11 As shown, the second side-pushing mechanism 8 also includes two guide rods 84; wherein, the second side-pushing support 81 can be set on the machine base 12 of the production line 1, and can be located below the left synchronous belt of the double synchronous belt conveyor mechanism of the production line 1; the second side-pushing cylinder 82 is set on the second side-pushing support 81 in a horizontal direction, and its movable end is distributed horizontally to the left; the connecting plate 95 is set vertically on the movable end of the second side-pushing cylinder 82; the side-pushing block 83 can be set on the right side of the top of the connecting plate 95, and can also be located on the left side of the production line 1; the second side-pushing cylinder 82 can be used to release the first fixture 2 in the clamping mechanism 9. Then, the side push block 83 drives the first fixture 2 located at the third station to the right to the second station. The right end of the side push block 83 is used to push the left part of the first fixture 2 to the right. The two guide rods 84 can be set at the front end and rear end of the right plate of the connecting plate 95 in the horizontal direction, and their free ends can be inserted into the left support plate of the left synchronous belt of the double synchronous belt conveyor mechanism, and can slide horizontally along the left support plate to guide the left and right movement of the connecting plate 95, so that the side push of the side push block 83 is more stable. Of course, the second side push mechanism 8 is designed in this way, which makes the structure simple and the side push convenient.

[0110] Furthermore, such as Figure 10 and Figure 12 As shown, the clamping mechanism 9 includes: a first clamping cylinder 91, a first clamping rod 92, a second clamping cylinder 93, a second clamping rod 94, a connecting plate 95, and a mounting plate 96;

[0111] like Figure 10 As shown, the first pressing cylinder 91 is mounted on the first side-push cylinder 72 via the mounting plate 96;

[0112] The first clamping rod 92 is disposed at the movable end of the first clamping cylinder 91;

[0113] like Figure 11 As shown, the connecting plate 95 is vertically arranged at the movable end of the second side push cylinder 82, and the side push block 83 is arranged on the first side of the top of the connecting plate 95.

[0114] like Figure 12 As shown, the second pressing cylinder 93 is located on the second side of the top of the connecting plate 95, and its movable end passes through the connecting plate 95 and is located at the bottom of the side push block 83;

[0115] like Figure 12 As shown, the second clamping rod 94 is located at the movable end of the second clamping cylinder 93;

[0116] The first clamping cylinder 91 and the second clamping cylinder 93 are used to drive the first clamping rod 92 and the second clamping rod 94 to simultaneously clamp the first fixture 2 located at the second work station.

[0117] It should be noted that, as described above, the clamping mechanism 9 includes: a first side clamping mechanism and a second side clamping mechanism. The first side clamping mechanism is equivalent to the right side clamping mechanism and includes the first clamping cylinder 91, the first clamping rod 92, and the mounting plate 96, as well as the clamping connecting plate 97. The second side clamping mechanism is equivalent to the left side clamping mechanism and includes the second clamping cylinder 93, the second clamping rod 94, and the connecting plate 95.

[0118] Among them, such as Figure 10 As shown, the mounting plate 96 is horizontally mounted on the first side-push cylinder 72; the first clamping cylinder 91 is horizontally mounted on the mounting plate 96, with its movable end facing horizontally to the left; the clamping connecting plate 97 is vertically mounted on the movable end of the first clamping cylinder 91 and has an inverted U-shaped structure. The clamping connecting plate 97 is located to the left of the side-push connecting plate 74, and there is a gap between the two. In this way, when the first side-push mechanism 7 pushes the first fixture 2 to the left to the third station, it can prevent the side-push connecting plate 74 from touching the clamping connecting plate 97 during its leftward movement, thus avoiding interference between the side-push connecting plate 74 and the clamping connecting plate 97. Figure 9As shown, the two first clamping rods 92 are respectively located at the front end and rear end of the left plate of the clamping connecting plate 97, and their ends are provided with inclined surfaces for clamping the right side of the first fixture 2; of course, the two first clamping rods 92 are located between the two side push rods 73.

[0119] like Figure 11 As shown and as mentioned above, the connecting plate 95 is vertically positioned at the movable end of the second side push cylinder 82, as... Figure 12 As shown, the side push block 83 can be located on the right side of the top of the connecting plate 95, or it can be located on the left side of the production line 1, as shown. Figure 13 As shown, two second clamping cylinders 93 can be disposed on the top left side of the connecting plate 95, and their movable ends respectively penetrate the connecting plate 95 and are located at the bottom of the side push block 83 (e.g. Figure 12 As shown); Figure 12 As shown, two second clamping rods 94 (which can be clamping bars) are respectively disposed at the movable ends of two second clamping cylinders 93; wherein, the bottom of the side push block 83 is provided with two sliding grooves, both of which pass through the left and right ends of the side push block 83, and the two second clamping rods 94 are slidably installed in the two sliding grooves at the bottom of the side push block 83, and are respectively connected to the movable ends of the two second clamping cylinders 93, so that the two second clamping rods 94 are embedded in the bottom of the side push block 83, as shown. Figure 12 As shown, the ends of the second clamping rods 94 are all provided with inclined surfaces for clamping the left side of the first fixture 2, and the bottom of the side push block 83 is also provided with two support bars. The two support bars are used to support the sliding of the two second clamping rods 94 and improve the smoothness of the sliding of the two second clamping rods 94.

[0120] When the first fixture 2 is located at the third station, the first clamping cylinder 91 is used to drive the two first clamping rods 92 to move toward the first fixture 2, and the second clamping cylinder 93 is used to drive the two second clamping rods 94 to move toward the first fixture 2, so as to simultaneously clamp the first fixture 2 located at the third station toward each other, so that the first fixture 2 is fixed after positioning; wherein, in order to ensure that the second side clamping mechanism and the second side pushing mechanism 8 do not affect each other when they work, when the second side pushing mechanism 8 pushes the first fixture 2 to the right to the second station, the second clamping cylinder 93 can drive the two second clamping rods 94 to retract to the left until they are completely located at the bottom of the side pushing block 83, so as to prevent the two second clamping rods 94 from protruding from the bottom of the side pushing block 83 and thus preventing them from affecting the side pushing of the second side pushing mechanism 8;

[0121] In other words, such as Figure 10 As shown, the first clamping mechanism of the clamping mechanism can be integrated onto the first side pushing mechanism 7, such as... Figure 12 As shown, the second clamping mechanism can be integrated into the second side push mechanism 8, thereby making the positioning device compact, reliable and efficient.

[0122] Therefore, this solution provides a special positioning method for a fixture on a synchronous belt in an assembly line. First, the synchronous belt conveyor of the assembly line transports the first fixture. Then, the blocking block of the front blocking mechanism rises, blocking the first fixture at the first station in the flow direction. Next, the lifting block of the front lifting mechanism and the lifting plate of the rear lifting mechanism rise simultaneously, lifting the first fixture to the second station, causing the first fixture to leave the synchronous belt conveyor of the assembly line. Then, the side-push pressing mechanism pushes the first fixture to the left to the third station and presses it again, thus completing the positioning and fixing of the first fixture. After that, the lifting assembly of the assembly line lifts the second fixture. After the second fixture is removed, the side-push pressing mechanism pushes the first fixture to the right to the second station. Then, both the front and rear lifting mechanisms descend, causing the first fixture to fall onto the first station of the synchronous belt conveyor of the assembly line. Finally, the front blocking mechanism removes its obstruction, and the first fixture is transported to the next station along with the synchronous belt conveyor.

[0123] Furthermore, the positioning device provided in this solution operates as follows:

[0124] The first fixture moves with the synchronous belt of the production line. A front-end blocking mechanism prevents the first fixture from moving to the first station. Simultaneously, the front and rear lifting mechanisms lift the first fixture to the second station. A right-side pushing mechanism pushes the first fixture to the left to the third station. A clamping mechanism clamps the first fixture. The production line's lifting assembly lifts the second fixture. Once the second fixture is removed, the clamping mechanism releases the first fixture. The left-side pushing mechanism pushes the first fixture to the right to the second station. Simultaneously, the front and rear lifting mechanisms lower the first fixture back to the first station of the production line. The front-end blocking mechanism releases the first fixture. The synchronous belt of the production line delivers the first fixture to the next station.

[0125] In addition, the positioning device is designed in this way, which has the following beneficial effects:

[0126] 1. This case achieves the positioning of the offset fixture, avoids the use of complex fixture conveying structures, and adopts a relatively simple and reliable assembly line synchronous belt, ensuring the stability and reliability of the equipment structure.

[0127] 2. The design of the lifting mechanism and lifting fixture is adopted, which avoids interference with the synchronous belt when the fixture moves left and right, reduces the failure rate by about 5%, and greatly improves the operational stability;

[0128] 3. The side-push clamping mechanism can achieve positioning and clamping functions. The mechanism is compact and can be arranged in small spaces.
