Description

Technical Field

[0001] The utility model relates to the technical field of clamping tools, in particular to a non-marking clamping tool for a cleaning machine. Background Art

[0002] In the surface mounting process of the electronics manufacturing industry, reflow soldering and wave soldering are commonly used processes, and are even the processes that high-precision and complex PCBAs must go through. The use of various fixtures is indispensable in these processes. However, in the production process, these fixtures, jigs, carriers, and accessories that must be removed for reflow soldering and wave soldering will inevitably come into contact with flux residue, rosin, grease, oil, and even be directly sprayed with flux. For example, in the process of jigs passing through wave soldering, the use of clean fixtures, jigs, and production accessories can not only reduce costs, but also improve processing efficiency and enhance market competitiveness. Therefore, it is necessary to clean fixtures, jigs, carriers, and accessories that must be removed for reflow soldering and wave soldering. However, manual cleaning of PCBAs has problems such as inconsistency in manual operation, low operator affinity for chemicals, emotional operation, continuity of employee attendance, and high production costs. These problems make it an inevitable trend to replace manual labor with cleaning equipment.

[0003] After the cleaning machine cleans the mask, when the plate is transported to the cleaning machine loader grip fixture, marks are easily generated on the four corners of the plate, and a manual wiping process must be added to eliminate the marks, which brings a lot of instability to the product. For this reason, the existing grip fixture must be modified to eliminate the manual wiping process and improve product quality. Therefore, it is necessary to invent a non-marking clamping tool for the cleaning machine to solve the above problem. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a non-marking clamping tool for a cleaning machine, comprising a first connecting plate, a grip plate and a second connecting plate, wherein the first connecting plate is located between the grip plate and the second connecting plate.

[0005] Furthermore, a first wedge block is fixedly installed at the middle position of each of the four sides of the first connecting plate.

[0006] Furthermore, the grip plate is provided with hemispherical contact masks that are evenly distributed.

[0007] Furthermore, the second connecting plate is provided with support blocks and a first limiting plate which are centrally symmetrically distributed.

[0008] Furthermore, a first connecting block is fixedly installed at each of the four corners of the first connecting plate, and the first connecting block is movably connected to the supporting block via a slot.

[0009] Furthermore, a first connecting rod is fixedly mounted on the Grip plate.

[0010] Furthermore, the first connecting plate is provided with a first connecting hole movably connected to the first connecting rod.

[0011] Furthermore, a first spring sleeved on the outside of the first connecting rod is provided between the Grip plate and the first connecting plate.

[0012] Furthermore, the first limiting plate is fixedly installed at the center of the side line of the second connecting plate, and the support blocks are fixedly installed at the four corners of the second connecting plate.

[0013] Furthermore, a second connection hole is provided in the middle of the first limiting plate, and third connection holes that are mirror-symmetrical are provided on both sides of the second connection hole.

[0014] Furthermore, a second connecting rod is movably installed in the second connecting hole.

[0015] Furthermore, the second connecting rod is fixedly connected to a second wedge block, and a second spring is provided between the second wedge block and the second connecting hole and is sleeved on the outside of the second connecting rod.

[0016] Furthermore, one side of the second wedge block contacts and fits with the first wedge block, and a second limiting plate is fixedly installed on both sides of the other side of the second wedge block, and the second limiting plate is movably installed in the third connecting hole.

[0017] Beneficial effects of the utility model:

[0018] 1. The hemispherical contact mask provided on the grip plate proposed by the present invention prevents particles in the environment from being trapped between the product and the grip plate when the grip plate clamps the product, thereby preventing particles in the environment from being adsorbed on the grip plate when the grip plate holds the product, thereby preventing contact marks from being left on the product. This eliminates the need for manual wiping of the contact surface between the product and the grip plate, eliminating the manual wiping process, shortening production time, and improving production efficiency.

[0019] 2. When the Grip plate proposed by the present invention compresses the first spring between the Grip plate and the first connecting plate, the second wedge block is facilitated to buffer the force exerted on the first connecting plate, so that the force exerted on the first connecting plate is evenly distributed to the second wedge block through the first wedge block, thereby facilitating a better fit between the Grip plate and the product when in contact and less likely to leave marks, thereby improving product quality.

[0027] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0028] Please refer to Figures 1 to 4 The utility model proposes a non-marking clamping tool for a cleaning machine. First, the product is clamped with a Grip plate 2. The Grip plate 2 is provided with a notch. The Grip plate 2 is provided with equidistantly distributed hemispherical contact masks 21 at the contact position with the product. The hemispherical contact masks 21 provided on the Grip plate 2 make it difficult for particles in the environment to be stored between the product and the Grip plate 2 when the Grip plate 2 clamps the product, thereby preventing particles in the environment from being adsorbed on the Grip plate 2 when the Grip plate 2 holds the product, thereby preventing contact marks from being left on the product, making it unnecessary to manually wipe the contact surface between the product and the Grip plate 2, eliminating the manual wiping process, shortening production time, and improving production efficiency.

[0029] When the Grip plate 2 is used to support the product, a first connecting rod 22 is fixedly installed on the Grip plate 2, and a first connecting hole 12 is opened on the first connecting plate 1 to adapt to the first connecting rod 22. The first connecting rod 22 is movably installed in the first connecting hole 12. The first connecting rod 22 is movably installed in the first connecting hole 12. A first spring 23 is provided between the Grip plate 2 and the first connecting plate 1 and is sleeved on the outside of the first connecting rod 22. The product will provide a force to the Grip plate 2, so that when the Grip plate 2 moves toward the first connecting plate 1, the Grip plate 2 will drive the first connecting rod 22 on the Grip plate 2 to move in the first connecting hole 12 on the first connecting plate 1, so that the Grip plate 2 will compress the first spring 23 between the Grip plate 2 and the first connecting plate 1. At this time, the first spring 23 provides a buffer for the Grip plate 2, which can prevent the Grip plate 2 from leaving marks when it contacts the product, and at the same time facilitates the Grip plate 2 to fit better with the product, thereby improving the stability of the support.

[0030] Please refer to Figure 5When the grip plate 2 compresses the first spring 23 between the grip plate 2 and the first connecting plate 1, the first spring 23 will provide a force to the first connecting plate 1, so that the first connecting plate 1 will move toward the second connecting plate 3. During this process, a first wedge block 13 is fixedly installed on each of the four sides of the first connecting plate 1 near the middle position of the second connecting plate 3. The first wedge blocks 13 on the opposite sides of the first connecting plate 1 are symmetrically arranged. A first connecting block 11 is fixedly installed at the four corners of the first connecting plate 1. The second connecting plate 3 is respectively provided with a support block 31 and a first limiting plate 32 which are symmetrically distributed in the center. The first limiting plate 32 is fixedly installed at the center of the edge line of the second connecting plate 3. The support block 31 is fixedly installed at the four corners of the second connecting plate 3. The first connecting block 11 is movably connected to the support block 31 through a slot. A second connecting hole 33 is opened in the middle position of the first limiting plate 32, and a mirror-symmetrical third connecting hole 34 is opened on both sides of the second connecting hole 33. The second wedge block 36 is fixedly connected to the second connecting rod 35, and one side of the second wedge block 36 contacts and fits with the first wedge block 13. A second limit plate 37 is fixedly installed on both sides of the other side of the second wedge block 36. The second limit plate 37 is movably installed in the third connecting hole 34. When the first connecting block 11 moves, the first wedge block 13 on the first connecting plate 1 will contact the second wedge block 36 and push the second wedge block 36, so that the second wedge block 36 will move toward the first limit plate 32. A second spring 38 is provided between the second wedge block 36 and the second connecting hole 33 and is sleeved on the outside of the second connecting rod 35. The second wedge block 36 will compress the second spring 38 between the second wedge block 36 and the first limit plate 32, thereby facilitating the buffering of the second wedge block 36, so that the force applied to the first connecting plate 1 is evenly distributed to the second wedge block 36 through the first wedge block 13, so that the grip plate 2 can fit better when in contact with the product and is not prone to leaving marks, thereby improving product quality.

[0031] When the second wedge block 36 moves toward the first limiting plate 32, it will drive the second connecting rod 35 to move in the second connecting hole 33. At the same time, the second wedge block 36 will drive the second limiting plate 37 to move in the third connecting hole 34, thereby maintaining the stability of the second wedge block 36 when moving. The second connecting plate 3 facilitates dynamic adjustment of the Grip plate 2 when holding the product, thereby facilitating the Grip plate 2 to protect the product when holding the product, and is less likely to leave marks, thereby improving product quality.

[0032] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
