Description

Technical Field

[0001] The present invention relates to the field of semiconductor technology, and in particular to a positioning, locking and unlocking mechanism for tin printing and mounting on a ceramic substrate. Background Art

[0002] The production process of conventional-sized thermoelectric cooling products consists of soldering the upper and lower substrates with the semiconductor crystal grains in the middle using solder paste. The upper and lower substrates of the cooling plate are square ceramic sheets with a thickness of only 1mm. Their positioning and fixing are relatively difficult. To improve efficiency, the production process requires that the substrate printing solder paste, particle placement and upper substrate buckle mounting be achieved in one clamping between different machines.

[0003] For example, publication number "CN220135767U" discloses "a semiconductor refrigerator and semiconductor refrigerator production system," comprising: a first ceramic substrate, a second ceramic substrate, a die, and a guide vane; the top surface of the first ceramic substrate is provided with a die mounting area and a blank area; the die is mounted on the die mounting area; the second ceramic substrate is mounted on the die; and the guide vane is fixed to the blank area for laser coding. However, in actual application, this type of device cannot achieve simultaneous clamping of multiple products, requiring individual positioning during production, resulting in low production efficiency. Summary of the Invention

[0004] In response to the problem in the prior art mentioned in the background technology that multiple products cannot be clamped synchronously and the production efficiency is low, the present invention provides a ceramic substrate tin printing and mounting positioning locking and unlocking mechanism, which can achieve the effect of synchronous clamping, unlocking and positioning of multiple products, thereby greatly improving the production efficiency of the products.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions.

[0006] A positioning, locking and unlocking mechanism for tin printing and mounting on a ceramic substrate includes a carrier plate and a fixed base plate. The carrier plate is detachably connected to the fixed base plate. The carrier plate is provided with a plurality of placement grooves, and telescopic parts are provided in the placement grooves. The fixed base plate is provided with a plurality of movable connecting parts, and a pushing part capable of driving the movable connecting parts to move is provided on the fixed base plate. When the carrier plate is connected to the fixed base plate, the movable connecting parts are connected to the telescopic parts. In the present application, the fixed base plate remains in a fixed state during use, and a movable connecting member is provided on the fixed base plate, wherein the movable connecting member can move relative to the fixed base plate, and a carrier plate is also connected to the fixed base plate, wherein the carrier plate can remain relatively fixed with the fixed base plate during operation, that is, the carrier plate also remains in a fixed state during operation, and a placement groove is provided on the fixed base plate, the shape of the placement groove can adapt to the shape of the product, and the placement groove is used to place the product, wherein a telescopic member is provided in the placement groove, wherein the telescopic member can move relative to the placement groove, and the telescopic member can lock and unlock the product by relative movement, and when the telescopic member abuts the product, the product can be fixed and locked, thereby ensuring the fixed stability of the product, and when the telescopic member is away from the product, the fixed locking effect of the product can be eliminated; in the present application, since a telescopic member is provided in each placement groove, and each placement groove is a groove-type structure, only connecting each telescopic member together through the carrier plate for movement will make the structure of the carrier plate more complicated, which is not conducive to production. Therefore, in this application, the movable connecting part is connected to the telescopic part. Since the fixed base plate and the carrier plate are independently connected, the movable connecting part is connected to the telescopic part, and the placement slot can be avoided to connect the various telescopic parts together. In addition, the movable connecting part is connected to a pushing part, and the staff can drive the movable connecting part to move through the pushing part, and then drive all the telescopic parts to move synchronously through the movable connecting part, thereby achieving the synchronous unlocking and locking effect of each placement slot, thereby greatly improving production efficiency.

[0007] Preferably, the placement groove is connected to a slide groove, the slide groove is slidably connected to the telescopic part, and an elastic part is provided at the bottom of the slide groove, and the elastic part abuts the telescopic part. A slide groove is provided in the placement groove, and the telescopic part is provided in the slide groove. The telescopic part can perform relative displacement in the slide groove, and an elastic part is provided inside the slide groove. The elastic part can provide a restoring force to the telescopic part, thereby ensuring that when the carrier plate is not connected to the fixed base plate, that is, when the movable connection part is not connected to the telescopic part, the telescopic part can be reset by the elastic part, so that before the carrier plate is connected to the fixed base plate, the telescopic parts on the carrier plate can all return to a fixed initial position, thereby ensuring that when the carrier plate is connected to the fixed base plate, all the movable connection parts can be connected to the telescopic part, thereby ensuring the positioning accuracy of the telescopic part.

[0008] Preferably, the carrier plate includes a carrier base plate and a carrier cover plate, the slide groove is provided on the carrier base plate, and the carrier cover plate is provided with a hollow groove. When the carrier cover plate is connected to the carrier base plate, a placement groove is formed between the hollow groove and the carrier base plate. The carrier plate includes a carrier base plate and a carrier cover plate. The hollow groove is machined on the carrier cover plate, and then the carrier cover plate is placed on the carrier base plate to form the placement groove. Therefore, if the placement groove is connected to the slide groove, it can be directly machined on the carrier base plate. Moreover, before placing the carrier cover plate, the telescopic member and the elastic member can also be placed in the slide groove, thereby ensuring smooth assembly.

[0009] Preferably, the carrier cover plate has a thickness smaller than that of the product, and the telescopic member only partially abuts the product in the product thickness direction. Setting the carrier cover plate's thickness smaller than the product thickness prevents subsequent processing steps from being interfered with by the carrier cover plate. Furthermore, the telescopic member only partially abuts the product, thereby preventing interference with subsequent processing steps.

[0010] Preferably, the chute includes an abutment angle, and the chute is provided with a clearance waist hole. The abutment angle provided on the chute can fix and constrain the reset position of the telescopic member, ensuring that each telescopic member can return to a specific position under the drive of the elastic member, thereby enabling the movable connection member to be connected to multiple telescopic members synchronously; wherein the clearance waist hole is provided on the chute, wherein the clearance waist hole allows the movable connection member to pass through and then connect with the telescopic member, and the shape of the clearance waist hole also enables the movable connection member to slide in the clearance waist hole.

[0011] Preferably, the telescopic member is provided with an unlocking hole, and the movable connecting member is provided with an unlocking column. When the carrier plate is connected to the fixed base plate, the unlocking column is connected to the unlocking hole. When the movable connecting member is pushed by the pushing member, the telescopic member is driven to move by the unlocking column. The telescopic member is provided with an unlocking hole, and the movable connecting member is relatively provided with an unlocking column. The unlocking column can be engaged with the unlocking hole, so that the unlocking column does not cause relative displacement between the unlocking hole and the unlocking column during the process of unlocking and locking the telescopic member, thereby ensuring that the telescopic member can move to the specified position during the unlocking and locking process. At the same time, since the fixed base plate has its own weight and friction resistance, the telescopic member can be limited and self-locked by the movable connecting member during use. The telescopic member can only be driven to move by the movable connecting member, thereby ensuring the locking stability of the telescopic member to the product. In the unlocking process, the telescopic member will not reset and interfere with the product removal.

[0012] Preferably, the telescopic member is positioned at the corner of the placement slot, and is provided with mutually perpendicular limiting side plates, allowing the telescopic member to move diagonally along the diagonal corners of the placement slot. The telescopic member is positioned at the corner of the placement slot, thereby enabling the telescopic member to constrain the product in position, and by constraining the corners, the telescopic member is constrained in multiple directions. Specifically, the constraining structure comprises mutually perpendicular limiting side plates, thereby ensuring stable corner constraint.

[0013] Preferably, the carrier plate is provided with a take-up slot, which is connected to the placement slot. The take-up slot is provided on the carrier plate, and the take-up slot is connected to the placement slot, so that the staff can take the product from the side of the placement slot, ensuring the smoothness of taking the product.

[0014] Preferably, the fixed base plate is provided with a positioning pin, and the carrier plate is provided with a positioning hole, and the positioning pin is engaged with the positioning hole. The positioning pin is provided on the fixed base plate, and the positioning hole is provided on the carrier plate.

[0015] Preferably, the fixed base plate is provided with a sliding unit, the movable connecting member is connected to the sliding unit, the fixed base plate is provided with a return spring, and the return spring is connected to the movable connecting member. The sliding unit is provided on the fixed base plate, wherein the sliding unit includes but is not limited to a structure such as a slide rail, and the sliding unit can enable the movable connecting member to slide relative to the fixed base plate, and the fixed base plate is provided with a return spring, which can drive the movable connecting member on the fixed base plate to return to its initial position, thereby ensuring that it can be aligned and connected with the telescopic member and ensuring the smooth movement of the movable connecting member.

[0016] The beneficial effects of the present invention are as follows: (1) It can achieve the effect of simultaneous clamping, unlocking and positioning of multiple products, so that multiple products can be processed simultaneously, thus greatly improving the production efficiency of the products; (2) By providing an elastic member, the elastic member can provide an elastic squeezing effect for the telescopic member, so that when the tool plate is removed, the telescopic member can still clamp the product to ensure stability.

[0042] During use, the corresponding carrier plate 1 is placed on the fixed base plate 2, and the positioning pins 23 and the positioning holes 17 on the fixed base plate 2 are connected to ensure the connection stability between the carrier plate 1 and the fixed base plate 2, wherein the elastic member 14 drives the telescopic member 12 to abut against the abutment angle 131, ensuring that the position of the telescopic member 12 is fixed, so that the unlocking columns 211 on the movable connecting member 21 can be engaged and connected to the unlocking holes 121, and then the movable connecting member 21 is driven to move by the pushing member 22, and the telescopic member 12 can be driven to move by the unlocking column 211, and the elastic member 14 is squeezed so that the telescopic member 12 is away from the abutment angle 131, so that the product 3 can be placed in the placement groove 11, wherein since the corners of the product 3 cannot cover the abutment angle 131, when the telescopic member 12 is reset, the telescopic member 12 abuts against It is on the corners of the product 3 without abutting the abutment corner 131, thereby ensuring that the telescopic part 12 can lock the product 3 and apply pressure to the product 3, thereby ensuring the stability of the lock; when all the products 3 are placed, the elbow clamp can be used to drive the movable connection part 21 to reset, and after the movable connection part 21 is reset, it can drive the unlocking column 211 to return to the initial position, thereby ensuring that all products 3 can be locked at the same time, and then the carrier plate 1 is taken out. Since the telescopic part 12 can lock the product 3 under the action of the elastic part 14, the stability of each product 3 can be guaranteed when the carrier plate 1 performs automatic solder paste printing, particle placement, upper substrate buckling and other processes. After completing each process, the carrier plate 1 can be placed on the fixed base plate 2 to repeat the unlocking steps to take out the product 3.
